Our verdict

Yes, if you hate damp, smelly fabric bath mats and like the idea of a stone mat that dries itself, and you will treat it gently. MatMend absorbs water from wet feet quickly, dries in about a minute and needs only a wipe, with a 1-year warranty. But diatomaceous earth mats lose absorbency as pores clog, can crack, and similar mats have been recalled abroad over asbestos contamination, while the page shows no test results. MatMend scores 5.1 out of 10, held back by price, durability and missing safety evidence.

The short version

  • A rigid bath mat made from compressed diatomaceous earth.
  • Absorbs water from feet quickly; dries in under a minute, the page says.
  • 15.4 x 23.6 inches, about 0.4 inches thick, with a non-slip backing.
  • Wipe clean; no laundry.
  • $49.99 plus shipping on 4 October 2026; three for $119.99 and five for $179.99.
  • 1-year warranty and 30-day guarantee.
  • Absorbency can fade over time; the stone can crack.
  • Some diatomaceous earth mats sold in Japan and Taiwan were recalled in 2020 over asbestos.
  • Best trait: quick-drying and laundry-free.
  • Biggest drawback: no published safety testing and a high price.
  • Our score: 5.1 out of 10.

Pros & cons

Stone bath mats are a clever, popular product. The cons are about how long they work, how fragile they are, and safety evidence.

What we like

  • Absorbs water from wet feet quickly and the surface dries in about a minute, according to the page
  • No laundry: wipe with a damp cloth instead of washing a fabric mat
  • Smooth, cool, spa-like feel that many owners like
  • Non-slip backing, 15.4 x 23.6 inches and about 0.4 inches thick
  • 1-year warranty and 30-day money-back guarantee

What we don't

  • Diatomaceous earth mats lose absorbency over time as pores clog with soap and skin oils
  • Rigid and brittle: can crack if dropped or stood on unevenly
  • Similar diatomaceous earth mats were recalled in Japan and Taiwan in 2020 after asbestos was found; the page does not show test results
  • "Eliminates mold and bacteria", "prevents hidden floor damage" and "100% safe" are overstated
  • $49.99 plus shipping for one is high; similar stone mats are widely sold for less

How it works

Diatomaceous earth, also called diatomite, is a soft, chalk-like rock made from the fossilised shells of tiny algae called diatoms. Their shells are full of microscopic pores, so the rock is light and highly absorbent. Pressed into a board, it soaks up water and lets it evaporate from the large surface area of its pores.

Where diatomaceous earth is used

Diatomaceous earth has many everyday uses: as a filter material for swimming pools, beer and wine, as a mild abrasive in some polishes and toothpastes, as a natural insecticide powder, and in building materials. In Japan, diatomaceous earth plaster and household goods became popular for their moisture control, which is where the stone bath mat trend took off before spreading worldwide.

Natural vs calcined diatomaceous earth

Raw, or "natural", diatomaceous earth is mostly amorphous silica. Heating it at high temperatures, called calcining, makes it harder and whiter but can convert some silica into crystalline forms. Fine crystalline silica dust is harmful to breathe over long periods. Most bath mats are made by binding diatomaceous earth with other materials and pressing it into boards; the page does not say how MatMend is made.

Why bathrooms get damp

Showers release a lot of warm water vapour, which condenses on cooler surfaces such as tiles, mirrors and fabric. If a bathroom is poorly ventilated, damp lingers, and fabric mats on the floor stay wet for hours. That combination of warmth and moisture is ideal for mould and mildew. A mat that dries quickly removes one damp surface, but ventilation, such as an extractor fan or open window, matters more for the room as a whole.

  1. Place it on a dry, flat floor

    Step 1: Lay MatMend flat outside the shower or bath on a clean, level floor, with the non-slip backing down. Make sure it sits evenly so it does not rock when stepped on.

  2. Step on with wet feet

    Step 2: The porous stone draws water from your feet into millions of tiny pores, so footprints fade within seconds and your feet feel drier.

  3. Let it dry and wipe occasionally

    Step 3: Water spreads through the stone and evaporates into the air. The page says the surface dries in under a minute. Wipe it with a damp cloth when dusty.

Why it dries so quickly

When you step on with wet feet, water is pulled into the pores by capillary action, so the surface looks dry within seconds. The water then evaporates from inside the stone into the room. The page's graphic shows wet footprints fading over 60 seconds.

Why fabric mats stay damp

Fabric mats hold water in their fibres and dry slowly, especially in humid bathrooms. Damp fabric can smell and grow mildew, which is why they need regular washing.

What the backing does

The page says MatMend has a non-slip bottom layer that keeps it stable on smooth bathroom floors.

How absorbency changes over time

Over months, soap residue, skin oils and minerals from hard water can clog the stone's pores, so it absorbs more slowly. Many stone mat makers recommend light sanding to open the pores again. MatMend's FAQ only mentions wiping, which avoids the dust issues sanding can create.

Who it's for

MatMend suits people who find fabric mats damp, smelly and annoying to wash, households with small bathrooms where a wet mat makes the room feel damp, and people who like a clean, modern look.

It suits people less well if they want softness underfoot, have small children who might drop it, or are uneasy about diatomaceous earth safety without test results.

Why MatMend appeals

The drying effect is genuinely satisfying, and videos of footprints vanishing are why stone mats became popular. No laundry, no musty smell, and a sleek grey slab that looks more spa than student flat. Testimonials describe a high-end feel and no more wet floors.

The appeal of less laundry

Bath mats are one of those household items that need washing more often than people realise, ideally weekly in a busy bathroom. Removing them from the laundry pile saves water, energy and time, which is part of the appeal of stone mats beyond the drying trick.

A typical shower

You step out of the shower onto the cool stone. Your footprints darken the surface, then fade within seconds. Your feet feel drier than on a soaked towel mat. By the time you have dried off, the mat looks dry again. Once a week, you wipe off dust and hair with a damp cloth.

A typical household morning

In a family bathroom, several people may shower within an hour. A fabric mat would be soaked by the third shower; a stone mat dries between each one if there are a few minutes in between. Back-to-back showers can leave it damper, but it recovers once the bathroom airs.

Who gets the most value

People who shower daily and dislike washing bath mats, and those in humid bathrooms where fabric never quite dries, get the most value.

Who gets the least

People who like a soft, warm mat, and those whose bathrooms have uneven floors where a rigid slab might rock and crack, get the least.

What it will not do

It will not stay as absorbent forever without care, soften a cold floor, or replace a towel for drying your whole body. It is not a non-slip surface in the bath or shower itself.

What happens in a humid bathroom

In a small bathroom with no extractor fan, the air after a shower is close to saturated with moisture. Water in the mat evaporates more slowly when the air is already damp. Stone mats still feel drier than fabric, but in very humid rooms the drying time stretches. Opening a window or running a fan speeds it up.

As a gift

Stone mats are a popular housewarming gift. Because they can crack and absorbency fades, pair it with a note on care.

Families with young children

Children splash water everywhere at bath time, and one owner on the page says the mat absorbs it all instantly. A quick-drying mat keeps floors drier. On the other hand, children may stand on edges or drop it while moving it, so supervise and keep it flat.

Older adults

Wet bathroom floors are a common place for falls, and older adults are most at risk. A mat that dries the soles of your feet quickly may help, and the page says the backing keeps it from sliding. But a rigid mat with a raised edge could also be a trip hazard for people with shuffling gaits. Grab bars and a non-slip mat inside the shower or bath do more to prevent falls.

Renters and small flats

In small bathrooms without good ventilation, a damp fabric mat can make the whole room smell musty. A stone mat that dries quickly helps keep things fresher. It is also easy to move when you change homes, as long as it is wrapped well to avoid cracking.

People with sensitive skin or allergies

Damp fabric mats can harbour dust mites and mould, which can bother people with allergies. A quick-drying stone surface avoids some of that. Wipe it regularly so dust and skin flakes do not build up.

Holiday homes and guest bathrooms

In bathrooms used occasionally, fabric mats can sit damp after guests leave. A stone mat dries itself and needs no washing between visits, which suits holiday lets and guest rooms.

  • People tired of damp, smelly fabric bath mats and frequent mat washing
  • Small bathrooms where a quick-drying mat helps keep floors tidier
  • Anyone who likes a modern, minimal stone look

Who should skip it

  • Households where the mat might be dropped, kicked or stepped on hard by children; stone can crack
  • Anyone wanting a soft, warm surface underfoot
  • People who will not check product testing given asbestos concerns with some diatomaceous products
  • Budget buyers; similar mats cost less

How much does MatMend cost, and what do you get?

MatMend costs $49.99 plus shipping for one mat on the offer page on 4 October 2026, with three for $119.99 and five for $179.99, including free shipping on bundles. You get one rigid grey bath mat made from compressed diatomaceous earth, about 15.4 by 23.6 inches and 0.4 inches thick, with a non-slip backing.

Is it good value?

Diatomaceous earth bath mats are widely sold online and in shops, often at lower prices than $49.99. MatMend's design and warranty are pleasant, but a similar mat from a retailer that publishes asbestos testing may offer better value and more peace of mind.

Cost over time

A fabric bath mat might cost $10 to $20 and last a year or two with regular washing, plus the cost of laundry. A stone mat at $49.99 needs no washing but may need replacing if it cracks or loses absorbency. Over two or three years, costs can end up similar; the stone mat's advantage is convenience and the quick-drying feel rather than savings.

What the bundles suit

Three mats suit a home with several bathrooms or a kitchen sink drying spot. Five suit gifting. One is enough to see whether you like the feel.

How well does MatMend work?

MatMend should absorb water from wet feet quickly when new, with the surface drying in about a minute, so you avoid damp, smelly fabric mats and laundry. Owners on the page describe instant absorption and dry floors. Over months, diatomaceous earth mats tend to lose absorbency as pores clog with soap and oils, and the rigid stone can crack if dropped or stood on unevenly.

The brand's material and testing claims. Image: MatMend

Nobody on our team has used MatMend, so this section is based on the page, how diatomaceous earth mats generally perform, and owner reports.

Drying performance

Diatomaceous earth mats do absorb water quickly when new, and the vanishing-footprint effect is real. Owners on the page describe instant absorption and dry floors.

Absorbency over time

Owners of stone mats in general often report that absorbency slows after months of use as pores clog. Keeping the mat dry between uses, avoiding soapy water dripping onto it and wiping it regularly help. Some brands supply sandpaper to restore the surface; see the safety section below before doing that.

Mould and bacteria

Because the surface dries quickly, mould is less likely to grow than on a damp fabric mat. That is a real benefit. "Eliminates" mould and bacteria goes too far: dirt and skin cells on the surface still need wiping, and the underside can trap moisture on a wet floor.

Durability and cracking

Compressed diatomaceous earth is rigid and fairly brittle. Dropping it, standing heavily on an edge, or placing it on an uneven floor can crack it. The FAQ compares it to ceramic and advises care.

How it compares when new and after a year

When new, the mat drinks up water almost instantly. After many months of daily showers, owners of stone mats commonly notice footprints lingering longer. Keeping it clean slows the decline. If absorbency drops a lot within the 1-year warranty, contact support; the page does not say whether reduced absorbency counts as a defect.

Feel under bare feet

Stone mats are hard, so they do not give underfoot like fabric or foam. For people standing for a minute or two to dry off, that is usually fine. For people with sore feet or joint pain who stand longer at the sink, a cushioned mat may be more comfortable.

Noise and weight

Stone mats are heavy for their size and can clunk if set down on tiles. That weight also helps them stay in place.

Comfort

The surface is firm and cool. Owners describe it as spa-like. People who like a soft, warm mat may not enjoy it in winter.

What owners say about using it

The page shows 48 reviews and six testimonials praising the look, quick absorption, dry floors and the feel underfoot, including one family with splashing children.

Reading the testimonials

The testimonials are short and enthusiastic, focused on first impressions: the look, the instant absorption and the feel. None describes how the mat performs after several months, which is when absorbency and cracking issues usually appear. Several use stock enthusiastic phrasing and describe a "mat set", which may hint that testimonials were written for a related product.

Safety: diatomaceous earth and asbestos

What happened with recalls

Diatomaceous earth is not asbestos, and asbestos is not deliberately added to these mats. But in December 2020, Japan's authorities and retailers recalled diatomaceous earth bath mats and coasters after testing found asbestos contamination, and Nitori, a large Japanese retailer, recalled millions of products, including in Taiwan. SGS's report on the Japanese recalls summarises the issue, and Wikipedia's article on Nitori notes the recall.

Why it matters

Asbestos is a known cause of serious lung diseases. Intact products release few fibres; the risk rises when contaminated material is broken, drilled or sanded, creating dust. That is why advice following the recalls warned against breaking or sanding the mats.

Testing for asbestos

Asbestos testing on consumer products is usually done by accredited laboratories using microscopy. A credible report names the lab, the method, the product and batch, and the result. If a seller cannot provide that, treat safety claims cautiously.

What MatMend says

The page says the material is toxin-free and safe for pets and children, and a graphic mentions third-party quality control. It does not show asbestos test certificates or name the testing lab.

What this means for you: ask the seller for asbestos test results for your batch before buying, and do not sand, cut or break the mat. If a mat cracks, dispose of it carefully, without crushing or sanding, according to local guidance.

Silica dust

Some diatomaceous earth products are heat-treated (calcined), which can create crystalline silica. Breathing fine silica dust over time is harmful. Again, the risk comes from dust; avoid sanding or grinding the mat indoors.

Other stone mat sellers

Some stone mat brands now publish third-party asbestos test results for their products. That is the standard to look for. If MatMend can provide similar documentation, buyers can make an informed choice.

What to do if your mat cracks

If a stone mat cracks, stop using it to avoid cutting feet on sharp edges. Do not break it into smaller pieces or crush it. Wrap it in a bag and dispose of it according to local household waste guidance. If you have concerns about contamination, contact the seller and your local authority for advice.

Are MatMend's claims true?

MatMend's quick-drying claim holds up for a new mat, though the page itself shows about 60 seconds rather than seconds. Other claims go too far. "Eliminates mould and bacteria" overstates what quick drying does, "never wash a bath mat again" ignores the care stone mats need, and "100% safe for pets and children" is unproven, since the page shows no asbestos test results.

"Absorbs water and dries in seconds"

The surface dries quickly when new; the page itself shows about 60 seconds.

"Eliminates mould and bacteria growth" and "naturally antimicrobial"

Overstated. Quick drying discourages mould; the stone is not an antimicrobial treatment.

"Never wash a bath mat again, no cleaning required"

The FAQ says wipe when dusty. Stone mats also need care to keep pores open.

"Prevents hidden floor damage"

A quick-drying mat may reduce damp under the mat, but no bath mat protects subfloors from leaks.

"Rock-solid anti-slip protection"

The backing helps stop the mat sliding. A stone surface with soap on it can still be slippery.

"100% safe for pets and children" and "toxin-free"

No test results are shown.

"Lasts for years"

Possible with care, but cracking and clogging can shorten life.

Is MatMend better than a cotton, microfibre or teak bath mat?

MatMend dries faster than fabric mats and never needs laundering, but it is hard, can crack and costs more. Cotton and microfibre mats are cheap, soft and washable, and rotating two keeps them fresh. Teak or bamboo mats are another no-laundry option. Many identical stone mats sell for less, so if you want stone, choose a seller that publishes asbestos testing and a clear warranty.

MatMend vs other stone mats

Many stone mats look identical. Choose one from a seller that publishes asbestos testing, offers a clear warranty, and gives realistic care instructions.

MatMend vs fabric mats

Fabric mats are soft and washable. Washing two cotton mats in rotation keeps them fresh. If you do not mind laundry, they are cheaper and comfier.

MatMend vs teak mats

Teak or bamboo slatted mats let water drain and air dry, look spa-like and do not crack like stone. They do not absorb water from your feet.

MatMend vs microfibre mats

Microfibre bath mats are soft, absorbent and dry faster than cotton. They can be machine-washed and are cheap. For people who want softness and do not mind washing, they are an easy choice.

MatMend vs a towel on the floor

Many people simply step onto a towel. It works, but it adds to the laundry and stays damp. A stone mat removes that chore at the cost of softness.

MatMend vs a quick-dry rug

Some washable rugs and runners are designed to dry quickly and resist slipping. They offer softness and washability, with less of the vanishing-footprint effect.

MatMend vs anti-slip shower mats

Inside the shower or bath, a suction-cup anti-slip mat helps prevent slips on wet surfaces. A stone mat is for outside the shower. For older adults, both together, plus a grab bar, give the best protection.

Is MatMend legit, and what should you check before buying?

MatMend is a real product with a 1-year warranty, but we found no independent reviews or test reports, and the page claims third-party quality control without showing results. Similar diatomaceous earth mats were recalled in Japan and Taiwan in 2020 after asbestos was found. Before buying, ask the seller for third-party asbestos test reports, never sand or break the mat, and place it on a level floor.

Ask about testing

The page shows no asbestos test results.

What to do: ask the seller for third-party asbestos test reports before buying, and keep a copy.

Do not sand or break it

Dust is the main hazard with diatomaceous products.

What to do: do not sand, drill or cut the mat. If it cracks, do not crush or sand it; follow local disposal guidance.

Floors

Uneven floors can make rigid mats rock and crack.

What to do: place it on a flat, level surface and check that it does not wobble.

Children and pets

Stone mats are heavy and can break.

What to do: keep children from lifting or standing on edges of the mat, and supervise toddlers in the bathroom.

Ventilation

A quick-drying mat does not fix a damp bathroom.

What to do: run the extractor fan during and after showers, or open a window, to clear moisture and reduce mould on walls and ceilings.

Shipping damage

Stone mats can crack in transit.

What to do: inspect the mat as soon as it arrives, photograph any damage and contact support straight away.

Returns of heavy items

Returning a heavy stone mat can cost more in postage than a fabric mat.

What to do: check whether return shipping is free under the 30-day guarantee, and keep the original box and packaging.

Expectations

Stone mats are a different experience from fabric mats.

What to do: try it for a couple of weeks before deciding; some people love the cool, firm surface and others miss softness.

Underfloor heating

Diatomaceous mats on heated floors are usually fine, but check the backing material's heat tolerance.

How to buy MatMend the smart way

  1. Ask for asbestos test results, then decide whether to order from the MatMend order page (opens MatMend in a new tab).
  2. Buy one mat first; the three-pack is preselected.
  3. Check shipping on a single mat.
  4. Inspect the mat for cracks when it arrives and report damage straight away.
  5. Note the 30-day guarantee and 1-year warranty.

How to use MatMend for the best results

Place MatMend on a clean, dry, level floor so it does not flex. Rinse soap off your feet before stepping on it when you can, and let it dry fully between uses, leaning it against a wall if your floor is often wet. Wipe it weekly with a damp cloth, avoid harsh chemicals and bleach, and lift it occasionally so the underside dries.

  1. Place it on a clean, dry, level floor.
  2. Step off the shower onto it rather than dripping soapy water on it.
  3. Let it dry fully between uses; lean it against a wall if your floor is often wet.
  4. Wipe it weekly with a damp cloth.
  5. Avoid harsh chemicals and bleach.
  6. Keep it out of direct contact with puddles.
  7. Handle it with both hands when moving.

Keeping it absorbent

Rinse soap off your feet before stepping on it when you can. Wipe away oils from lotions. In hard water areas, minerals can build up; gentle wiping helps.

Drying the underside

If your bathroom floor is often wet, lift the mat occasionally to let the underside dry, so moisture does not sit underneath.

A monthly care routine

Once a month, lift the mat, wipe both sides with a damp cloth, check the edges and surface for hairline cracks, and let it air for a few hours before putting it back. Note how quickly footprints fade compared with when it was new; if it is much slower, absorbency is declining.

Using it beyond the bathroom

The FAQ suggests kitchens for drying dishes, under pet bowls and in laundry rooms. Under a dish rack, it absorbs drips; under a water bowl, it catches spills from messy drinkers. Keep it clean in kitchens, where food residues can clog the pores faster.

Positioning in the bathroom

Place it where you step out of the shower or bath, close enough that you do not drip across the floor first. Keep it away from where water pools around the shower tray, so the underside does not sit in water.

Cleaning around it

Lift the mat when you mop the bathroom floor, let the floor dry, then put the mat back. Mopping around it leaves damp edges underneath that take longer to dry.

Choosing where to buy

If you like the idea of a stone mat but want more reassurance, compare sellers. Look for published asbestos test results, a clear warranty that covers cracking from normal use, and honest care instructions. Those three things matter more than the brand name, the packaging or how many glowing reviews appear on a single sales page.

Dealing with hard water

In hard water areas, minerals left as water evaporates can build up on and in the surface, slowing absorption and leaving a faint white film. Wipe with plain water regularly, and dry your feet a little on a towel first if your water is very hard.

Watching for wear

Check the corners and edges every few weeks. Small chips can turn into cracks, and rough edges can catch toes. A mat with a crack across it should be replaced.

Storing it when not in use

If you take it out of use, for example when redecorating, store it flat, dry and supported, not leaning on an edge or stacked under heavy items, which can crack it.

First use

Unpack the mat carefully, remove any protective film, wipe it with a damp cloth and let it dry. Test absorption with a small splash of water to see how quickly it disappears, so you have a baseline for later.

Most questions are about whether stone mats work and whether they are safe. They absorb water from feet quickly and dry fast, especially when new, though absorbency can drop over time. Intact mats with no contamination are generally considered low risk, but some mats sold in Japan and Taiwan were recalled in 2020 over asbestos, so ask for testing and avoid sanding or breaking them.

Do diatomaceous earth bath mats work?

Yes, especially when new. They absorb water from feet quickly and dry fast. Absorbency can drop over time.

Are stone bath mats safe?

Intact mats with no contamination are generally considered low risk. Some mats sold in Japan and Taiwan were recalled in 2020 over asbestos. Ask for testing and avoid sanding or breaking them.

Why does my stone mat smell?

It usually should not, but if water sits underneath on a wet floor or the surface is dirty, smells can develop. Wipe it, dry the underside and improve bathroom ventilation.

Can stone mats stain?

Yes. Hair dye, coloured toiletries and oils can mark the porous surface. Wipe spills promptly.

Can I sand my stone mat?

Some brands recommend it to restore absorbency. Given contamination concerns, avoid sanding unless the seller provides testing showing the mat is asbestos-free, and then only outdoors with a mask, following their instructions. MatMend's FAQ does not recommend sanding.

How long do stone bath mats last?

Often a year or more with care. Cracks and clogging end their life sooner.

Are stone mats cold?

They feel cool, especially in winter. Some people like it; others prefer fabric.

Can I use MatMend in the kitchen?

The FAQ suggests it for drying dishes or under pet bowls. Keep food-contact items clean.

Can I put it in direct sunlight to dry?

Gentle airing is fine. There is no need for sunlight; the mat dries in room air. Avoid extreme heat, which may affect the backing.

Is MatMend heavy?

Stone mats of this size are noticeably heavier than fabric mats. The page does not give a weight.

Can I use a stone mat on carpet?

Stone mats need a hard, flat surface. On carpet they can flex and crack, and moisture can soak into the carpet underneath.

Does MatMend come in other sizes or colours?

The page shows one grey design. Other stone mat brands offer larger sizes and colours if you need a different look or fit.

Is MatMend eco-friendly?

The page describes a plastic-free design. Avoiding regular laundry saves water and energy. A stone mat that cracks early and goes to landfill reduces the benefit, so careful handling matters.

Can I use it outside?

It is designed for indoor use. Outdoors, rain would saturate it and frost could crack it.

Does it absorb a lot of water at once?

It absorbs typical amounts from wet feet well. A large spill, such as an overflowing bath, will exceed what the stone can hold and needs mopping.

What if the backing peels off?

The non-slip backing is what stops the mat sliding. If it peels or wears, the mat may move on smooth floors. Contact support under the 1-year warranty, and meanwhile place a thin non-slip pad underneath.

Are stone mats good for people with mobility issues?

They dry feet quickly, which can help, but they are rigid with an edge. People who shuffle or use walking aids should check that the mat does not create a trip hazard, and may prefer a thin, flexible non-slip mat.

Does MatMend need sealing?

No. Sealing would block the pores that make it absorbent.

Can two mats be placed side by side?

Yes, for larger showers. Make sure both sit flat and close together so toes cannot catch an edge.

Can I clean it with vinegar?

The FAQ only mentions wiping with a damp cloth. Acids can react with some stone materials; stick to plain water unless the seller advises otherwise.

Will hair stick to it?

Hair sits on the surface and can be wiped or brushed off easily.

Will it work with a walk-in shower?

Yes. Place it outside the shower area where you step out. For curbless wet rooms, keep it beyond the area that gets splashed.

Do stone mats get mouldy?

Less often than fabric mats, because they dry quickly. Mould can still grow on dirty surfaces or underneath on a wet floor.

Is MatMend slippery?

The backing helps it stay put. The surface can be slippery with soap; keep it clean.

Is MatMend worth it?

If you love the idea of a quick-drying, laundry-free mat and will treat it carefully, it does the job. Ask for asbestos testing first, compare prices with similar stone mats, and do not sand or break it.

Frequently asked questions

What is MatMend?

MatMend is a rigid bath mat made from compressed diatomaceous earth, a porous natural material. It absorbs water from wet feet quickly and lets it evaporate, so the surface dries fast. Owners describe instant absorption when new; absorbency can fade over months.

How much does MatMend cost?

On 4 October 2026 the offer page listed one MatMend at $49.99 plus shipping, three for $119.99 and five for $179.99, with free shipping on bundles. Similar stone mats are widely sold for less, so compare and ask each seller for asbestos test reports.

How big is MatMend?

The page shows 15.4 x 23.6 inches and about 0.4 inches thick. It is rigid, so it needs a level floor outside the shower where it will not flex. Measure the space before ordering, because returning a breakable item can be awkward.

How do I clean MatMend?

The FAQ says wipe it with a damp cloth when dusty. Over time, stone mats can lose absorbency as pores clog; follow the brand's instructions and do not use harsh chemicals. Never sand it to restore the surface, because dust is the main hazard with diatomaceous products.

Can MatMend break?

Yes. The FAQ says to take care not to drop it, like ceramic. It should sit flat on a level floor so it does not flex. If it cracks, stop using it and do not break it up yourself. Ask the seller how to dispose of it.

Do diatomaceous earth bath mats contain asbestos?

Diatomaceous earth itself is not asbestos, but in 2020 some diatomaceous earth bath mats and coasters sold in Japan and Taiwan were recalled after asbestos contamination was found. The MatMend page mentions third-party quality control but shows no test results. Ask for testing evidence and avoid sanding or breaking the mat.

Is MatMend slippery?

The page says it has a non-slip backing and anti-slip surface. A stone surface can still be slippery with soap or oil on it, so keep it clean. Place it on a dry, level floor so it does not slide or rock.

What is the guarantee?

The page shows a 30-day money-back guarantee and a 1-year warranty. Check the mat for cracks as soon as it arrives and report shipping damage straight away. Ask the seller for asbestos test reports, and keep a copy with your order confirmation.
