What is the best tile for a shower floor that won't be slippery when wet?

Porcelain tile with a textured or matte finish is the best choice for shower floors, providing excellent slip resistance when wet while maintaining durability and water resistance.

For maximum safety, look for porcelain tiles with a COF (Coefficient of Friction) rating of 0.42 or higher when wet. Textured porcelain tiles, including those with raised patterns, grip dots, or natural stone textures, offer superior traction compared to glossy ceramic options. Smaller format tiles (2x2 inch mosaics or 4x4 inch tiles) also provide more grout lines, which act as natural slip-resistant channels for water drainage.

Natural stone options like slate or honed travertine work well but require more maintenance with regular sealing. Avoid polished marble, glossy ceramic, or large format smooth tiles in shower floors, as these become dangerously slippery when wet. The tile surface should feel slightly rough to the touch - if it's completely smooth, it's likely too slippery for safe shower use.

In Ottawa's climate, proper installation is crucial for both safety and longevity. Licensed contractors will ensure proper slope (1/4 inch per foot toward the drain), waterproof membrane installation, and appropriate grout selection. The subfloor must be structurally sound to prevent tile cracking, and vapor barriers are essential in our humid conditions.

Consider penny round mosaics or hexagon tiles for both style and function - their numerous grout lines provide excellent grip. For maintenance, use pH-neutral cleaners and avoid wax-based products that can create slippery surfaces.
