Bathroom Suite Tiling FAQs
How do I calculate tile for an entire bathroom renovation?
Separate your bathroom into three distinct zones: 1) Bathroom Floor, 2) Shower or Tub Surround Walls, and 3) Vanity Backsplash. Calculate the square footage of each zone independently because floor tiles typically use larger non-slip porcelain (e.g. 12"×24"), while shower walls often use subway or decorative glazed tiles. Add 15% waste buffer to each zone.
Should I tile under the bathroom vanity?
Yes, it is strongly recommended to tile the entire floor wall-to-wall before installing a freestanding or floating vanity. This makes future vanity replacements easy, ensures your floor height remains continuous, and prevents water damage to raw subfloors beneath the cabinet.
What is the best tile slip rating (COF/DCOF) for bathroom floors?
For residential bathroom floors subjected to standing water or wet bare feet, choose porcelain or ceramic tile with a Dynamic Coefficient of Friction (DCOF) rating of 0.42 or higher (matte, honed, or textured finishes). Avoid high-gloss polished marble or slick ceramic on wet floors.
