Pro tips

15% waste minimum on floors. Tile floors require 15% waste vs. 10% for walls. More cuts around fixtures, doorways, and uneven walls. Bump to 20% for diagonal patterns.

Backer board is non-negotiable. Cement backer board (Durock, HardieBacker) under all tile floors. Tile-on-wood-subfloor without backer board flexes and cracks within 2-3 years.

Heated tile floors: do it now or never. If you ever wanted radiant heated floors, install before tile goes down. Adds $5-$8/sq ft and pays back in comfort 365 days a year. Retrofitting later means tearing up the tile.

Frequently asked questions

Tile flooring cost per square foot?
Tile itself: $2-$15/sq ft (huge range). Grout/thinset/backer: $2-$3/sq ft. Pro install: $5-$10/sq ft. Total installed: $10-$30/sq ft.
Best tile for floors?
Porcelain is harder, denser, and rated for floors (look for PEI rating 4+). Ceramic is softer — fine for walls and light-traffic floors, scratches in heavy-traffic areas. Large-format (12×24, 24×24) is trendy and modern.
How long does tile flooring last?
50+ years easily. Tile floors in 1950s-built houses are often still in service. The grout might need recoloring or replacement every 10-15 years, but the tile lasts indefinitely.
Can I install tile flooring myself?
Yes — it's a learnable skill with a steep curve. Plan on 2-3 days for a small bathroom your first time. Rent a wet saw ($50/day). For showers or complex layouts, hire a pro — waterproofing mistakes are expensive.
