Expert Insights
Smart analysis for your Kitchen & Bath project
Full Surface Coverage
AI sums three walls (perimeter x height) plus the floor (width x depth) so you order tile for every shower surface.
Waste-Aware Box Count
Tile is sold in 10 sq ft boxes. AI adds 10% for cuts and breakage before dividing, so you do not run short mid-install.
Budget Benchmarking
Installed shower tile averages $12 per sq ft. AI multiplies area by the benchmark so you can spot overpriced quotes.
Calculation Formula
Tile Area = 2 x (Width + Depth) x Height + (Width x Depth)
Boxes = ceil(Area x 1.1 / 10) (10 sq ft per box, 10% waste)
Estimated Cost = ceil(Area x $12)

Frequently Asked Questions
How do I calculate tile for a shower?
Measure each wall (width x height) and the floor (width x depth), then add them together. Include 10% extra for cuts and waste. Divide total sq ft by the sq ft per box to find box count.
How much tile do I need for a standard shower?
A typical 4x4 ft shower with 8 ft walls needs about 80-90 sq ft of tile, including the floor. Add 10% waste for a total of roughly 90-100 sq ft.
How much does shower tile cost per square foot?
Ceramic shower tile runs $2-15 per sq ft, porcelain $3-20, and natural stone $7-30. Installation adds $8-15 per sq ft, bringing the average installed cost to about $12 per sq ft.
