Bathroom Floor Tiles: Slip Ratings, Sizes and What to Choose
A bathroom floor needs grip when wet. Choose a matt or textured porcelain, check the slip rating on the product page, and use a smaller tile or more grout joints in shower areas.
Understanding slip ratings
Slip ratings such as R9, R10 and R11 describe grip, and a higher number means more grip. R10 is a common choice for bathroom floors. Check each product page for its listed slip rating before you buy.
Finish and size
Matt and textured finishes grip better than polished ones. Larger tiles mean fewer grout lines, but a shower floor needs a slope to the drain, so smaller tiles follow the slope more easily.
Grout and sealing
Use a water-resistant grout and choose a colour close to the tile to keep joints looking clean. See our grout guide for colour and joint-width advice.
Common questions
- What slip rating do I need for a bathroom floor?
- R10 is a common choice for domestic bathrooms. Check the slip rating listed on each product page.
- Are large tiles suitable for a bathroom floor?
- Yes on flat areas. Use smaller tiles or mosaics where the floor slopes to a shower drain.
- Can I use wall tiles on a bathroom floor?
- No. Wall tiles are not rated for foot traffic. Use floor-rated porcelain.
