Frequently Asked Questions
What size tile is best for shower walls?
Subway tile (3"×6") is the most popular. Larger tiles (12"×24") create a modern look with fewer grout lines. For shower floors, use small tiles (2"×2" or smaller) that can follow the drain slope. Avoid large floor tiles in showers.
How much extra tile should I buy for a shower?
Buy 15% extra tile for showers. The many cuts around fixtures (showerhead, valve, niche, corners) create more waste than flat wall tiling. Keep leftover tiles for future repairs.
