The Bath Mat Stays Wet and Smells

The mat never dries between showers, the bathroom smells of mildew, and the fix is a mat with nothing in it for water to sit in, handled like the stone it is

The short answer

A fabric bath mat is a wet sponge by design. Water soaks into the fibres, the mat stays damp between showers, and mildew moves into the damp. Washing slows it down and the smell comes back, because the mat never gets dry. The stone mat ends the cycle by removing the fabric: water pulls into the stone's pores and dries fast, and there is nothing for mildew to live in. The madesmart stone mat holds 4.3 stars from 89 reviews at Target (November 2026), and 80 percent of reviewers would recommend it. Its own record carries two warnings, and both print here: the slab can break if it is dropped or knocked while you clean around it, and one owner reports the surface stopped soaking up water in under four months. Lift it flat, stand it up to dry, and refresh the surface when the soaking slows. Handled that way, it is the mat that stays dry.

Why does this happen?

Fabric holds water, and held water is the whole problem. A cotton or microfibre mat takes the water off your feet and keeps it. In a bathroom that gets used morning and night, the mat is damp for most of the day, every day. Mildew needs damp and time, and a fabric mat gives it both.

Washing treats the smell, not the cause. A hot wash kills what is growing in the mat this week. The mat goes back on the floor, gets wet again, and stays wet again. Owners who wash on a schedule describe the same cycle: clean for a few days, sour again by the end of the week.

Stone works the other way. Diatomite is full of tiny pores that pull water off the surface on contact, so your feet dry as you stand on it, and the water spreads thin through the slab and dries in minutes. The trade is real: the mat is hard underfoot, it feels gritty at first, and it is a slab that can break, not a rug you can drop in a hamper.

The fix, in order

The steps are ordered cheapest first. Stop at the one that solves it and skip the rest; the product is there only for where the free steps run out.

  1. Free step

    Hang the mat after every shower

    The free step first. A mat draped over the tub edge or a rail dries between showers; a mat left flat on the floor does not. Two mats in rotation, one drying while one is in use, is the routine that keeps fabric mats ahead of the smell for most bathrooms.

  2. Habit step

    Wash hot and dry it fully

    Wash the mat hot, then dry it all the way through before it goes back down. A mat put back damp starts the cycle again the same day. This holds the smell off for a while on a mat that still dries well.

  3. The product step

    Move to the stone mat

    The madesmart stone mat removes the fabric, so there is nothing to stay wet. Water pulls into the stone and dries in minutes. Read the care rows under the flaws before you buy: lift it flat, never drag it across the floor, and stand it on edge now and then so both sides dry.

  4. Habit step

    Refresh the surface when soaking slows

    If the stone stops pulling water in, the pores have filled with soap and skin oils. A light rub with fine sandpaper or a scouring pad, then a rinse and a full dry, opens the surface again. One owner in the record lost absorption in under four months; this is the row that answers it.

The evidence, in tiers

Tier 1 · The method

The method is the material split: fabric mats fail by holding water, so the fix is a mat that holds none. Drying speed, not washing strength, is what ends the mildew cycle.

Tier 2 · This product

Target's product record for the madesmart stone mat reads 4.3 stars from 89 reviews, with 80 percent of reviewers recommending it. The praise in that record is absorbency and drying speed, in those words, from owners who switched after fabric mats went mouldy or smelled.

The critical rows in the same record are printed on this page as care checks, not hidden: breakage while handling and cleaning, and one report of absorption loss in under four months.

Tier 3 · What owners report

Owners describe feet dry in seconds, no more mould, and a mat that is dry for the next person. The same record carries the hard-surface complaints too: a gritty feel some feet never get used to, and a hard edge you do not want to stub a toe on.

The alternatives, conceded where they win

Threshold Loofah Bath RugA soft loofah-style bath rug at TargetWins if you want softness underfoot and accept the hang-and-rotate routine. It is still fabric, so the drying discipline is the product.
Two fabric mats in rotationYour current mat plus one spareThe free answer where it works: one mat drying while one is down. It fails in bathrooms with no rail or room to hang a mat.
A wooden bath matSlatted wood mat that lifts feet off the floorDries well and feels warm. The slats and the floor under them still need cleaning, and the wood needs oiling to last.

The honest price comparison

The honest price comparison: the stone mat costs $26.99 once. The fabric route costs a mat a year in most bathrooms, plus the washes. The stone only wins if you handle it with care; a broken slab is the most expensive outcome on this page.

Questions people ask next

How do I clean a stone bath mat?

Wipe it down, rinse it, and stand it on edge to dry. For stains, a light rub with fine sandpaper lifts them out of the surface. Never soak it, and let it dry fully before it goes back down.

What if it stops soaking up water?

The pores have filled with soap and oils. Rub the surface lightly with fine sandpaper or a scouring pad, rinse, and dry it fully. The soaking comes back in most cases.

Is it slippery?

The stone surface grips wet feet well, and the mat sits flat and heavy on the floor. The gritty texture owners mention is part of that grip.

Can it break?

Yes. It is a stone slab. The record behind this page includes slabs broken while cleaning and inside a year of use. Lift flat, carry with two hands, and keep it off the edge of the tub.
