How to Estimate Tile for a Bathroom Floor
Calculate exact tile counts and waste percentages for a bathroom floor with cent-line layout techniques.
Bathrooms have unique layout challenges (toilets, vanities, drains) that require precise tile estimation to ensure a balanced border.
The Tile Calculation Model
Multiply the floor's square footage by the size of the tiles (e.g., 12x12). Because there are many cuts around fixtures, a 15% waste factor is recommended.
Layout Strategy
Instead of starting at a wall, snap a center chalk line and work outward. This ensures any cut tiles along the edges are of equal size, giving you a professional, symmetrical vanity-center finish.
