Is Rubber Flooring Waterproof? UK Expert Answer 2026
Is Rubber Flooring Waterproof?
Yes — solid rubber flooring is waterproof. Vulcanised solid rubber is completely impermeable to water and does not absorb moisture. This makes rubber flooring one of the best flooring choices for wet rooms, changing rooms, swimming pool surrounds, commercial kitchens, and outdoor areas exposed to rain. Rubber flooring is resistant to water ingress, mould growth, and bacterial contamination that affect other flooring types.
Why Rubber Flooring Is Ideal for Wet Areas
Rubber flooring has several properties that make it uniquely suited to wet environments:
- Zero water absorption — unlike timber, carpet, or certain vinyl products, solid rubber absorbs no water and will not swell, warp, or delaminate
- Slip resistant when wet — textured rubber surfaces maintain high wet slip resistance (PTV 36+ in BS EN 13036-4 pendulum testing). Many rubber products are rated R11 or R13 under DIN 51130 for wet anti-slip performance
- Mould and mildew resistant — rubber does not support mould or mildew growth in damp conditions, unlike carpet, timber, and some vinyl products
- Chemical resistant — resistant to cleaning chemicals, chlorine (swimming pool environments), and steam cleaning, making it easy to maintain hygienically
- UV stable (EPDM grades) — EPDM rubber flooring is outdoor-weatherproof, maintaining performance and appearance in direct sun and rain
Best Rubber Flooring for Wet Areas
| Application | Best Rubber Type | Key Feature |
|---|---|---|
| Commercial kitchen | Drainage rubber matting | Open grid drains water away from feet |
| Swimming pool surround | Rubber safety tiles (R11+) | High wet slip resistance, chlorine resistant |
| Changing rooms / showers | Drainage mat or studded rubber | Prevents pooling, hygienic, easy to clean |
| Outdoor terrace / decking | EPDM rubber tiles or grass mats | UV stable, weatherproof, non-slip |
| Car wash / vehicle bay | Heavy-duty ribbed rubber roll | High durability, chemical resistant |
| Wet room / bathroom | Rubber safety flooring | Waterproof, R11 rated, mould resistant |
Limitations: Where Rubber Flooring Can Let Water Through
While the rubber itself is waterproof, standard rubber flooring installations are not fully sealed systems. Water can penetrate at:
- Tile joints — the gaps between rubber floor tiles are not sealed unless grouted or bonded with waterproof adhesive
- Edges and perimeters — where rubber flooring meets walls or drains, without proper silicone sealing, water can track underneath
- Adhesive failure — if glued rubber tiles lift at corners, water can accumulate beneath, causing issues with the substrate
For genuinely waterproof rubber flooring installations in areas like wet rooms, showers, or pool surrounds, seal all joints and edges with waterproof silicone sealant, use waterproof rubber adhesive throughout, and ensure the substrate has adequate drainage fall.
Rubber Flooring vs Vinyl in Wet Areas
Both rubber and vinyl flooring are waterproof materials, but rubber outperforms vinyl in wet areas on most practical measures:
- Slip resistance — rubber's natural texture provides better wet grip than smooth vinyl sheet
- Durability — rubber lasts 15–25 years vs 10–15 years for commercial vinyl in heavy wet use
- Impact resistance — rubber cushions dropped items better, reducing both item damage and noise
- Chemical resistance — rubber withstands stronger cleaning chemicals and disinfectants
Vinyl wins on aesthetics and lower upfront cost. For function-first wet area installations, rubber is the better choice.

Frequently Asked Questions
Can I use rubber flooring in a bathroom?
Yes — rubber flooring is an excellent choice for bathrooms and wet rooms. Use rubber safety tiles or rubber sheet flooring with R11 wet slip resistance rating. Seal all joints and edges with waterproof silicone sealant to prevent water ingress beneath the rubber. Rubber flooring is warmer underfoot than ceramic tiles and more comfortable to stand on.
Does rubber flooring get slippery when wet?
No — quality rubber flooring with a textured surface (ribbed, studded, coin, or embossed pattern) maintains excellent slip resistance when wet. Look for products with a PTV (pendulum test value) of 36 or above (classified as 'low slip risk') in wet conditions, or products rated R11 or above under DIN 51130. Avoid smooth rubber flooring surfaces in wet areas as smooth rubber can be slippery when wet.
Is rubber matting suitable for outdoor use?
Yes — EPDM and SBR rubber are both suitable for outdoor use. EPDM rubber is UV-stable and weather-resistant, making it the preferred choice for permanent outdoor rubber flooring (playground surfaces, outdoor walkways, sports surfaces). SBR rubber will gradually degrade with prolonged UV exposure, so is better suited to covered outdoor areas. Both types are fully waterproof.
