Stepping into a wet shower should never feel like a gamble. The mat you choose decides whether your feet lock onto a textured surface or skate across bare acrylic — and the difference is almost always the suction cups underneath, not the color on top. This shortlist covers nine real, currently sold mats, sorted by what they actually do well: square mats that cover a whole standing area, long rectangular mats for soaking tubs, and a couple of quick-drying picks for people who hate pulling up a soggy slab.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Straight answer up front: match the mat’s shape to your shower floor first, because a 27″ x 27″ square and a 40″ x 16″ rectangle solve two entirely different problems. Everything below is a genuine, carefully vetted selection of the best bathroom shower mats for tubs, stalls, and stand-up showers alike.
Our Picks at a Glance
How To Choose The Best Bathroom Shower Mats
Two numbers decide whether a mat works in your bathroom: its footprint and its suction cup count. Get the footprint wrong and you’ll be standing on half bare floor. Get the suction count wrong and the mat will creep and buckle under your weight. Here’s what actually matters, in plain terms.
Measure your floor before you buy anything
Shower floors split into three real shapes, and each one wants a different mat. A square stall shower — the kind with a centered drain — suits a 27″ x 27″ square mat with a cut-out in the middle. A standard soaking tub takes a long rectangle, typically 27″ to 40″ long and about 15″ wide. A walk-in stall with a drain off to one side often fits a 24″ x 24″ square best. Pull out a tape measure and check both the length and width of the floor you’re covering, because a mat that hangs over the tub lip will curl at the edges.
Suction cups are the whole ballgame
Every mat here relies on dozens of small rubber cups that press flat against the floor and create a vacuum seal. More cups means more grip points spread across the surface, so the mat resists sliding when you shift your weight. A mat with 200 or more cups tends to hold firmer than one with 146, and the cups need a smooth surface to work at all. Textured, tiled, or refinished floors stop the seal from forming, which is why nearly every manufacturer warns against them.
Material changes how a mat feels and how long it lasts
TPE (a soft, rubber-like plastic blend that stays flexible) is the material of choice on most newer mats — it tends to feel gentler underfoot than PVC and, unlike older rubber, most of these formulations arrive odor-free. PVC mats (a firmer vinyl plastic) typically cost less and feel a bit softer than rubber but hold up differently over time. Natural rubber sits between the two: grippy and durable, though a few buyers notice an initial smell on some rubber versions.
Drainage holes keep a mat from turning into a swamp
Holes punched through the mat let water escape instead of pooling on top under your feet. Mats in this group range from 50 up to 483 drain holes, and the ones with the densest perforation dry noticeably faster between showers. That matters for hygiene: standing water trapped under a mat is what feeds the mildew and black spotting you see on old mats.

In‑Depth Reviews
1. OTHWAY Square Shower Mat, 27″x 27″ Extra Large
Our pick — 4.5★ from 800+ verified ratings; the strongest balance of quality and price.
The 27-inch square that covers an entire stand-in shower floor, drain and all.
Start with the number that decides everything here: 224 suction cups (the small rubber cups that press flat to create a vacuum seal). That’s the highest count of any square mat in this group, and it’s the reason this mat holds firm instead of creeping toward the drain. The 27″ x 27″ footprint covers a whole compact stall shower, and a large cut-out in the center leaves your drain unobstructed so water keeps flowing instead of pooling around your ankles.
What wins people over is how rarely it moves. Owners describe stepping in and feeling locked in place, with enough room to stand anywhere in the stall without the mat giving way — a few mark it as a straightforward fix for a slick floor at a reasonable price. The TPE (a soft, rubber-like material that stays flexible and typically arrives odor-free) is the reason it feels gentler underfoot than the firm PVC mats further down this list. It’s also foldable for storage and safe in the washing machine, so keeping it fresh takes almost no effort.
The catch is real but narrow: getting every single cup to seat takes a moment of patience on a larger square like this. Buyers report — as one put it, “Hard to get each tab stuck to floor. I ended up just doing around the edge. Works okay this way.” That’s the honest trade-off for the bigger footprint, and the fix is simple: dampen the floor, press from the center outward, and work the corners last. Also note that this mat, like every one here, needs a smooth clean surface — skip it over grout lines, textured, or refinished floors where cups can’t seal.
Where it wins the day
- 224 suction cups — the most of any square mat here, so it stays put through weight shifts
- 27″ x 27″ covers a full compact stall shower with room to stand anywhere
- Central drain cut-out keeps water running instead of pooling underfoot
- Soft TPE stays flexible, folds flat for storage, and is machine washable
Where it asks a little of you
- Seating all 224 cups takes patience the first few times — work center to edge
- Only for smooth clean floors; grout lines, tiled, or refinished surfaces break the seal
- Sold as a single mat, so larger showers need two
Choose this if: you have a square stall shower and want the grippiest, roomiest coverage with the least fuss after set-up.
Think twice if: your shower floor is textured or heavily grouted — no mat’s cups, including these, will seal on a rough surface.
2. Webos Bathtub Mat Non Slip, Extra Long Rubber
The long rubber mat that clings with 399 cups — the most suction points in this whole lineup.
If grip is the only thing you care about, this is the pick. It packs 399 suction cups under a 37.8″ x 15.4″ run — nearly double the cups of the OTHWAY square mat’s 224 — spread across a long stretch that covers most of a standard tub. More cups means more independent grip points, so the mat resists shifting even when you pivot to reach for the shampoo.
The grip is genuinely what people rave about here: users consistently describe it staying planted with no wandering, and several note the suction cups sit flat enough that you don’t feel them poking through the top. The surface is a soft matte rubber that stays comfortable underfoot across a long shower, and the large drain holes let water move through fast so the mat dries quicker between uses. It’s flexible enough to fold for storage and can go straight in the washing machine when it needs a real clean.
Here’s the honest limit: this rubber mat skips the thick cushioning some buyers expect. One owner sums it up cleanly — “Perfect size for standard tub; secures well, suction cups prevent movement, safer showering. No strong odor unlike old mat. Lacks cushioning, so 4 stars.” So if you want a pillowy, padded step, look elsewhere; if you want a broad, firmly anchored grippy surface with a smooth matte top, this delivers. It’s an easy recommendation for long tubs.
The standout: 399 suction cups on a 37.8″ x 15.4″ body — the highest cup count and longest coverage on this list, for buyers who want maximum grip spread across the tub.
The honest caveat: it’s built for grip and drainage rather than padding, so expect a firm, flat feel rather than a cushioned step.
The confident call: buy it for a long tub where staying power beats squish — the 399 cups will hold through the squirmiest showers.
Not your mat if: you specifically want a thick, cushioned surface underfoot.
3. BYTANA Shower Mat 24×24 Inch, 236 Suction Cups
A trim 24-inch square you can cut to fit — with 236 cups and 17 deep drain channels.
This one answers a question the other mats don’t: what if your shower isn’t a neat 27-inch square? The BYTANA ships at 24″ x 24″ and is designed to be cut down for compact areas, so you can trim it to the exact floor you have. Underneath sit 236 reinforced suction cups, and the maker rates its grip at three times stronger than standard mats in lab tests on ceramic and glass — a claim worth treating as a manufacturer figure rather than a promise, though the underlying cup count is genuinely high.
The drainage design is the real differentiator. Instead of a scatter of holes, it uses 17 deep drain stripes the maker rates at 1.2 liters of water per second — plain English: soap foam flushes away instead of pooling under your feet, which is what keeps the surface grippy mid-shower. The TPE is SGS-certified and BPA-free per the maker, and owners mention it stays comfortable through long showers while the ridges do their job underfoot. It’s the pick for a stall shower that needs a precise fit rather than a full-sized slab.
Two things to know before you commit. First, it wants smooth, non-porous surfaces — ceramic, glass, or acrylic — and won’t seat on rough floors. Second, grip is the one area where the feedback splits: most report great suction, but a minority find the cups don’t hold as firmly as hoped. If your floor is genuinely smooth and you press the mat down firmly before showering, this is a strong performer with the flexibility the squares above can’t match.
The fast read
- • 24″ x 24″ square you can trim to fit — rare flexibility for odd-sized stalls
- • 236 suction cups plus deep drain stripes rated at 1.2L/sec flushing
- • TPE the maker calls SGS-certified with zero BPA, designed to stay comfortable on long showers
Suits you if: your stall isn’t a standard square and you want the option to cut the mat to size with high cup coverage.
Look past it if: you need rock-solid suction every single time — this is the one pick where a few users find the grip less dependable, so a smooth floor is essential.
4. XIYUNTE Shower Mat Non Slip, 35″ x 16″ Soft TPE
A long tub mat with a perforation count that borders on a sieve — 483 drain holes.
The 35″ x 16″ mat carries 483 drainage holes — the densest perforation in this group by a wide margin — pushing water straight through so it drains and airs out fast. 180 suction cups anchor the underside, and the top surface uses a fine anti-slip texture designed to break up the water film that makes bare acrylic slick. Its TPE body arrives odor-free and stays soft underfoot.
What owners return to is the grip, which is the trait most mentioned in reviews — people describe it staying attached to a large soaker tub without drifting, soft underfoot, and good-looking enough to leave out. The drainage does the quiet work: water clears instead of sitting in low spots, so the mat stays cleaner between washes. When you do want a deep clean, you can rinse it or run it through the washing machine, then hang it or press it to the wall to air dry — no dryer needed.
The one recurring note is that this suction is strong enough to be a little stubborn: owners say pulling the mat up off the tub floor takes real effort at the end of a shower. That’s a nuisance to plan around, not a defect, because the same holding power is exactly what keeps it safe while you’re standing on it. Match it to a long tub and treat the removal tug as the cost of a securely anchored mat.
What you get: 483 drain holes and 180 suction cups in a 35″ x 16″ TPE mat — the fastest-drying, softest-feeling long mat here.
What you’ll notice: the suction holds so firmly that lifting the mat up afterward takes a deliberate pull.
Grab this one if: you have a long or soaker tub and want the quickest-drying, easiest-to-maintain surface.
Skip the effort if: you prefer a mat you can peel up with one hand — this one holds tight on purpose.
5. YINENN Bath and Shower Safety Mats, 40×16 inch
A 40-inch run that goes practically end to end, with a pebble texture under your soles.
This is the coverage play. At 40″ x 16″, the YINENN covers the full floor of a standard tub — owners describe it reaching the entire length, leaving no bare patches where a heel can slide. 200 suction cups hold it down across that long span, and the pebble-pattern surface adds a massaging feel underfoot rather than a flat rubber plane. It’s vinyl, which feels softer than raw rubber while staying sturdy, and 176 drain holes keep water circulating so the mat doesn’t sit in a puddle.
Durability is the quiet strength here. Owners talk about long-term use — one describes four years of service with the mat still secure and looking new, and the value angle comes up repeatedly: full-length coverage for a budget-friendly price. It’s machine washable, and the smooth vinyl wipes clean easily. Set it out in a ventilated spot for the first day if it arrives with any factory scent, then it’s ready to go.
The honest wrinkle is the very ends. A few owners find the mat a bit unstable at the tips, struggling to keep the far edges flat — which usually traces back to the last cups not fully seated on a slightly curved tub floor. Press every cup down firmly and the issue tends to settle. Pair this with the BYTANA’s smaller 24″ cut-to-fit footprint if you’re torn between maximum coverage and maximum precision.
What earns it a place
- 40″ x 16″ covers the full tub floor — no exposed slip zones
- 200 suction cups plus 176 drain holes for grip and drainage together
- Pebble-texture vinyl adds a cushioned, massaging step
- Machine washable and built to hold up over years of daily use
Worth a moment’s thought
- Far edges can lift if the last cups aren’t fully pressed down
- Vinyl may carry an initial factory scent — air it out first
- Smooth clean surfaces only; it won’t seal on textured floors
Made for: anyone who wants the whole tub floor covered, end to end, without paying more for it.
Less ideal if: your tub floor curves near the ends and you’d rather not fuss with seating the corner cups.
6. AmazerBath Shower Mat Non Slip, 40 x 16 Inches
The long tub mat with the deepest buyer base — and full-length coverage to match.
Among the long rectangular mats, this is the one with the largest following behind it, and the design explains why. At 40″ x 16″ it runs the full length of a standard tub, so there’s no exposed floor at either end. It’s also the wider of the two 40-inch mats here: compared with the Webos at 15.4″ wide, the AmazerBath adds coverage across the tub’s width, which means more of the floor you actually stand on gets covered.
200 suction cups and 176 drain holes do the working jobs — firm hold and quick water movement. Soft PVC (a firm but flexible vinyl plastic) gives it a cushioning feel, and owners describe it as sturdy and comfortable underfoot, easy to scrub, and good-looking over time without much effort. It stays clean and dry between uses, and because it’s machine washable, a full refresh is a single cycle away.
One fit-note matters for families: the non-slip surface works well for adults, but a small child standing in the tub may find it slicker than an adult’s steady weight would. It’s a weight-and-pressure quirk, not a flaw in the mat — an adult’s full foot pressure seats the surface texture where a toddler’s light step doesn’t. For a home with older kids and adults, it’s excellent; for very small children, add supervision and consider how the surface feels under their lighter step.
Why it holds the top spot for long tubs: 40″ x 16″ coverage at a full 16″ wide — wider than the Webos at 15.4″ — with 200 cups and 176 drainage holes underneath.
One thing to weigh: the surface is tuned for an adult’s weight, so a small child standing in the tub won’t get the same sure footing.
Best for: adult tubs that need every inch of floor covered, at a budget-friendly tier.
Reconsider if: you’re buying primarily for a toddler who stands in the tub — the surface responds best to adult weight.
7. HITSLAM Shower Mat Anti Slip, 27×27 Inch Square
A budget-friendly 27-inch square with a soft blue finish and 169 gripping cups.
Same footprint as the OTHWAY square at 27″ x 27″, but tuned for a lighter spend. 169 suction cups press into a smooth floor, and the dense drainage holes let water and air move through so the mat stays dry between showers. The PVC (a firm, flexible vinyl plastic) has a soft topside that people describe as comfortable underfoot, and it comes in a soft blue that reads clean and bright against a white tub.
What people like most is that it simply holds its footing: owners describe a mat that stays solidly fixed on the shower floor, easy to pull up and hang to drip dry when done, and free of mold over time. It’s also machine washable, which keeps the upkeep minimal. If you want the square format without stepping up in price, this covers the stall well.
Two small things come up. First, the grip can be hit or miss early on — a few find the cups don’t seal as readily as hoped, so dampening the floor first and pressing firmly helps. Second, the suction cups squeak against the surface, and one owner called the mat “Compact. Suction cups are squeaky. Easy to reposition if needed.” Neither is a dealbreaker: the squeak fades with use, and the easy repositioning is genuinely handy. Press it down before each shower and this square does the job.
The value read: a 27″ square that matches the OTHWAY’s footprint for less, with 169 cups and full drainage-hole coverage.
The quirk: some of the cups want a firmer press to seat, and the seal can squeak as it settles.
Your square if: you want the full 27-inch format at an entry-level tier and don’t mind a little press-to-seat.
Move on if: you’d rather not deal with any squeak or re-seating at all — the OTHWAY’s higher cup count is the smoother set-up.
8. Rubber Bathtub Mat Shower Mat Non-Slip, 31×14 Inch
A compact oval in natural rubber — the smallest footprint here, with 146 cups and 50 drain holes.
Not every tub is long. This one targets the compact and oval tubs the rectangular mats overhang, at 31″ x 14″ and shaped to sit neatly inside a narrower floor. It’s made of natural rubber, which the maker states is phthalate-free and non-toxic — with 146 suction cups underneath and a soft topside that stays comfortable across the whole family. 50 drainage holes let water flow off rather than gather, so it dries faster after use.
What it gets right is staying put: the mat’s most-praised trait is that it holds without slipping once the cups are seated, and owners note the length fits the tub well with the suctions gripping confidently. Used in a tub for daily showers, it stays where you press it, and the firm rubber resists the black algae and hard-water spotting that ages softer mats. It’s also easy to maintain — rinse or machine wash, then hang to air dry.
Be aware of two traits of the material. Natural rubber sometimes carries a funky odor for a while — one owner put it plainly: “Works great, length is a good fit for the tub. Has suctions on bottom, mat stays in place. Has a funky odor I cant seem to get rid of even after using it all week.” Airing it out well helps but doesn’t always erase it fast. Also, since it’s natural rubber, keep it out of direct sun and don’t leave it sitting in a wet area too long between uses, which protects the material.
The quick take
- • 31″ x 14″ oval fits smaller tubs that rectangles overhang
- • 146 suction cups and 50 drain holes — stable hold with fast drainage
- • Natural rubber the maker calls Phthalate-free, soft on the whole family’s feet
Right pick for: a smaller or oval tub where a full-length mat would buckle at the edges.
Know before buying: natural rubber can hold onto a smell for a while, and it prefers shade and a dry resting spot — so pair it with a routine.
9. Rubbermaid INSTAMAT Bath Tub Shower Mat, 27.2 x 15.2 Inch
A tub mat with a built-in hook so it dries on your showerhead instead of the floor.
The neat trick here is storage. A reinforced hook is molded right into the mat, so after your shower you hang it on the showerhead and let it drip dry — no flapping it out over the tub edge and no damp mat sitting in a puddle all day. At 27.2″ x 15.2″ it fits standard bathtubs and showers and, at 0.46 kg, it’s the lightest mat in this entire group — the Webos long rubber mat, by comparison, is far heftier — so hanging it is genuinely easy.
The material backing that convenience is worth noting. It’s made of 100% TPE, which the maker states is BPA-free and PVC-free — and its Microban-treated surface resists mildew growth. Owners describe it as good quality with no rubber smell, machine washable, and the drain holes keep water from pooling. The hanging-hook feature comes up again and again as the reason people keep it, and small details like rinsing and drying it before hanging keep it fresh longer.
One honest note about sizing and hold. The mat is a little smaller than some buyers expect for a generous tub, and the slip-resistance isn’t universal — most owners find it really sticks to the tub, but some report it shifting and buckling during use. Customers note the frustration directly, with one writing, “Does NOT stick to tub!… this mat does not stay suctioned to the tub and constantly moves while showering.” Since the mat relies on a smooth tub floor and a firm press to anchor, prepping the surface before you set it down makes the difference.
The singular feature: a reinforced built-in hook for hanging on the showerhead — the quickest-drying, easiest-to-store mat here, at just 0.46 kg.
The balancing note: suction holds dependably for most, but a minority find it shifts on some tub floors, so seat it firmly on a clean smooth surface.
The one to reach for if: you want a mat you can hang up and forget about, with mildew-resistant and BPA-free TPE underfoot.
Not the fit for: very large tubs — the 27.2″ x 15.2″ size leaves some floor uncovered.
Understanding the Specs
Suction cup count
Suction cups are the small rubber domes on the underside that press flat against the floor and create a vacuum seal. The more there are, the more separate grip points hold the mat down, so a high count resists shifting under your weight. The mats here run from 146 cups on the compact Rubber oval up to 399 on the long Webos rubber mat. Cups only seal on smooth, clean surfaces, so a rough floor wastes even a high count.
Drainage holes
Drain holes are the small perforations punched through the mat body that let water escape instead of pooling on top under your feet. They range from 50 on the compact oval mat to 483 on the XIYUNTE tub mat, and denser perforation means faster drying between showers and less water trapped underneath. That water is what feeds mildew and black spotting, which is why drainage is a hygiene feature as much as a comfort one.
Material: TPE versus PVC versus rubber
TPE is a soft, rubber-like plastic blend that stays flexible and usually arrives odor-free, which is why most newer mats use it. PVC is firmer vinyl plastic that feels soft underfoot and tends to cost less. Natural rubber is grippy and durable but can hold onto a smell for a while and prefers shade and dry storage. None of these is automatically better — match the feel you want to the upkeep you’ll actually do.
The surface rule that matters most
Every mat here — regardless of cup count or material — needs a smooth, clean, non-porous floor to seal. Textured, tiled, grouted, and refinished surfaces stop the cups from forming a vacuum, which is why the fitting instructions warn against them. Dampen the floor with a splash of water, set the mat down, and press outward from the center so each cup seats fully. Skip bath oils and additives too, since they lubricate the surface and undermine the grip.

Final Thoughts: The Verdict
For most shoppers, the bathroom shower mats winner is the OTHWAY Square Shower Mat, because its 224 suction cups and full 27″ x 27″ coverage lock a square stall shower down while the central drain cut-out keeps water moving — and it’s held up across the review pages with plenty of satisfied owners and the highest cup count of any square mat here. And if you want a tub mat you can simply hang up and forget, the Rubbermaid INSTAMAT solves cleanup with its built-in hook and lightweight 0.46 kg body. Whichever you pick, measure your floor shape first — a square mat in a long tub, or a long mat in a narrow stall, is the one mistake no suction cup can fix.
