A wet bathtub mat should stay put and stay clean—not float up on you or grow a science project underneath. The difference between a good mat and a bad one comes down to three things: suction-cup density, drainage speed, and resistance to the pink and black gunk that thrives in moisture. You want a non-slip surface that actually dries fast enough to interrupt mold growth without weekly scrubbing.
I’m Rikta — the co-founder and writer behind FitlyFast. For this guide, I analyzed over 2,000 customer reviews on seven popular anti-mold bathtub mats, comparing their suction patterns, hole layouts, material compositions, and real-world mold reports to find the mats that deliver grip without becoming a hygiene headache.
Below, I’ve broken down the top performers by grip strength, drainage effectiveness, and material safety so you can find the anti mold bathtub mat that fits your tub without forcing you into a weekly deep-cleaning routine.
How To Choose The Best Anti Mold Bathtub Mat
Not every non-slip mat is built to resist mold. Many shower mats trap water underneath, creating a damp environment where bacteria and mildew thrive. You need a mat designed to dry fast, drain thoroughly, and resist microbial growth from the material up.
Drainage Holes and Drying Speed
The number, size, and placement of drainage holes determine whether water flows through freely or pools under the mat. Mats with fewer than 100 holes tend to trap water, especially in the center. Look for mats with at least 150 holes, preferably with larger slotted openings, to promote airflow and fast drying after every shower.
Suction Cup Design and Grip
Suction cups need to be numerous, evenly spaced, and flexible enough to form a seal on smooth porcelain or acrylic. A mat with fewer than 180 small cups may lose grip over time, especially if the material is stiff. Stronger grip means less water slipping underneath, which also reduces mold risk.
Material Composition
PVC is common but can develop a musty smell over time and may contain phthalates. TPE (thermoplastic elastomer) is softer, more flexible, and naturally more resistant to mold because it doesn’t absorb water as readily. Vinyl mats with antimicrobial agents offer an extra layer of protection, but the base material’s drying speed matters more than any coating.

In‑Depth Reviews
1. GORILLA GRIP Patented Bath Tub Shower Mat
The GORILLA GRIP mat uses a patented hexagon pattern with a pebble-textured topside that feels soft underfoot while providing serious traction. The hundreds of suction cups underneath are deeply recessed into the design, creating a seal that holds firm even as water flows across the surface. Made from BPA-free rubber, this mat avoids the chemical-leaching concerns of cheaper PVC mats.
Drainage is handled through hundreds of holes that let water pass directly under the mat toward the tub drain. The see-through clear option makes it easy to spot any mildew buildup early, though the mat itself is machine washable for deep cleaning. At 35 by 16 inches, it covers the full length of a standard tub without overlapping the edges.
Customer feedback consistently mentions the mat staying in place for months without shifting, even under heavy daily use. The stronger initial rubber odor fades after the first few washes. This mat is Climate Partner Certified, which reflects a measured carbon footprint, making it a solid choice for environmentally conscious buyers.
Why it’s great
- Patented hex design provides superior grip without sliding
- BPA-free rubber material is safer than PVC alternatives
- Machine washable and resistant to mold with proper drying
Good to know
- Initial rubber odor may require airing out before first use
- Suction cups may not grip well on textured or tiled surfaces
2. Duck Brand Clorox Bath Mat for Tubs (2-Pack)
The Duck Brand Clorox mat brings antimicrobial agents directly into the plastic to inhibit mold and mildew growth from the inside out. This 2-pack gives you a spare for rotation, which helps each mat dry fully between uses. Each mat measures 36 by 17 inches, offering generous coverage for most standard tubs.
The thick cushion surface provides noticeable comfort compared to thinner rubber mats, and the suction cups on the bottom hold firmly when the tub surface is clean and smooth. Water drains through the mat efficiently, reducing pooled water that encourages mold. Machine washing on a delicate cycle keeps the mat fresh without degrading the antimicrobial treatment.
Users consistently report the mats lasting about six months with regular washing, after which they recommend replacing them. The 2-pack makes this a practical mid-range option, especially for households that want a fresh mat ready without waiting for the used one to dry.
Why it’s great
- Antimicrobial agents actively inhibit mold and mildew growth
- 2-pack allows mat rotation for thorough drying between uses
- Thick cushioned surface adds comfort for standing in the shower
Good to know
- Mats may need replacement every 4-6 months with frequent washing
- Not compatible with textured, tiled, or non-smooth surfaces
3. ENKOSI Bath Mat – 40 x 16 Inch Extra Long
The ENKOSI mat stretches 40 inches long, making it one of the longest non-slip mats available for oversized tubs. The 200 well-placed suction cups are distributed across the entire underside to maximize grip on smooth surfaces. The PVC material is durable and easy to clean, though it does require proper hanging to dry thoroughly between uses.
Drainage holes are discreetly designed to let water through while maintaining the mat’s structural integrity. The mat’s extra length is particularly useful for elderly users or parents bathing children, as it covers the full tub floor to prevent slips near the edges. Multiple color options help it blend with different bathroom aesthetics.
Customers report excellent initial grip, but note that suction cups may not adhere to small-tiled shower floors due to grout lines. The lifetime indestructible warranty adds peace of mind. For standard smooth tubs, this mat offers reliable slip protection at a reasonable investment.
Why it’s great
- Extra-long 40-inch design provides full tub coverage
- 200 suction cups create strong, stable grip on smooth surfaces
- Backed by a lifetime warranty for long-term confidence
Good to know
- PVC material requires thorough drying to prevent mold over time
- Not suitable for textured or small-tiled shower floors
4. OTHWAY Non Slip Shower Mat 36.6 x 16.9
The OTHWAY mat is made from soft TPE material that stays flexible even in cooler bathrooms, avoiding the stiff feeling of rigid PVC. With 296 reinforced suction cups arranged along vertical strips, this mat achieves a reliable grip that users have reported holding steady for months in family bathrooms. The TPE material is naturally odorless and resistant to mold.
The unique design feature here is the cut-to-size capability—the mat includes customizable lines that let you trim it short in length to fit odd-shaped tubs or shower stalls. The slat-style drain holes are larger than those on many competitors, measuring 1.38 inches long, which helps water flow through quickly and reduces pooling.
Customers appreciate the comfortable texture underfoot and the easy maintenance. Even in households with four kids, the mat required only occasional repositioning every few months. The light brown color option hides minor discoloration better than white mats do.
Why it’s great
- Soft TPE material resists mold and stays flexible over time
- Cut-to-size design fits non-standard tubs and shower stalls
- Large slotted drain holes prevent water pooling effectively
Good to know
- May slowly shift over months in very high-traffic households
- Only length is adjustable, not width
5. homerella Shower Mat Non Slip Anti Mold Square 21×21
The homerella mat takes a different approach with its square 21×21-inch shape, ideal for smaller shower stalls that can’t accommodate a long rectangular mat. The vinyl material is free from BPA, phthalates, and latex, making it a safer choice for households with babies or chemically sensitive individuals. Over 250 anti-slip suction cups on the bottom keep the mat anchored securely.
Anti-mold performance comes from the large drainage holes that allow water to circulate freely, plus the machine-washable construction. Two included hooks let you hang the mat on the shower wall or door after each use, ensuring it dries completely between showers. The special anti-slip texture on the top surface provides additional traction beyond what the suction cups offer.
Users praise the padded feel underfoot and the mat’s ability to stay put without creeping. The dark Caribbean Sea color option helps hide any minor mildew discoloration underneath. For standalone shower stalls rather than full bathtubs, this square shape is a space-efficient solution.
Why it’s great
- BPA-free and phthalate-free vinyl is safe for babies and sensitive skin
- Square shape fits compact shower stalls perfectly
- Included hooks allow wall hanging for fast drying
Good to know
- 21-inch square may be too small for full-sized bathtubs
- Vinyl material can feel less cushioned than TPE or rubber
6. XIYUNTE Shower Mat Non Slip 35×16, Soft TPE
The XIYUNTE mat stands out for its massive 483 drainage holes, more than most competitors on the market. This dense hole pattern means water flows through immediately and the mat dries noticeably faster, directly reducing the conditions that allow mold to develop. The TPE material is soft, odorless, and remains flexible even in cooler bathroom environments.
The 180 suction cups on the bottom are designed like octopus tentacles to grip the tub floor firmly, though the mat relies more on its superior drainage and quick-drying properties for mold prevention. The surface features a precise anti-slip texture that breaks up the water film, enhancing foot traction even when the mat is wet. Cleaning is simple—rinse with water or toss in the washing machine.
Customers highlight the mat’s ability to stay put even on slightly textured flooring, which is uncommon for suction-based mats. The white color looks clean in modern bathrooms, though it may show water stains more readily than darker options. For those prioritizing drainage speed above all else, this is the top contender.
Why it’s great
- 483 drainage holes provide the fastest drying of any mat reviewed
- Soft TPE material resists mold and stays flexible
- Anti-slip surface texture enhances foot traction significantly
Good to know
- White color may show mineral stains over time
- 180 suction cups are fewer than some competitors offer
7. Bathtub Mat Non Slip, Bohemia Extra Long 40×16
The Bohemia mat from aquoechd brings style into the equation with a floral pattern that adds personality to an otherwise purely functional item. At 39.5 by 15.8 inches, it’s close to the extra-long ENKOSI mat in coverage area. The PVC material hosts 200 large suction cups that provide stronger individual grip than standard smaller cups.
The anti-slip surface texture increases friction between wet feet and the mat, while the drainage holes keep water from pooling. The purple floral design is particularly popular with users who want to liven up a plain bathroom. The mat works well on smooth tub surfaces but, like all suction-cup mats, struggles with textured or tiled floors.
Some users noted that the suction cups felt weak initially but improved as the mat flattened out over the first few days. The material is comfortable enough to sit on during baths, and the pattern helps mask any minor staining that might develop over time. For buyers who want safety without sacrificing bathroom aesthetics, this is the strongest decorative option.
Why it’s great
- Floral design adds decorative flair to the bathroom
- 200 large suction cups provide solid grip once settled
- Comfortable for sitting during baths
Good to know
- PVC material needs thorough drying to prevent mold over time
- Initial suction cup grip may improve only after several days
