Once your shower tile is grouted and sealed, harsh bleach or gritty powders can etch stone and strip sealers. See how a targeted formula performs in our Zep Shower Tub & Tile Cleaner review.How to Use This Tile Calculator for Shower Walls & Floors
Calculating exact bathroom tile quantities requires separating vertical wall planes from the sloped mosaic shower floor pan. Our tile shower calculator and tile square footage calculator use the standard tile setter formula: measure the width and height of each shower wall in inches, multiply Width × Height ÷ 144 to convert square inches into square feet, add your recessed shampoo niche and curb faces, and apply a 10% to 20% waste factor for wet-saw perimeter cuts and layout offsets.
| Shower Enclosure Size | Wall Area (At 84" High) | Floor Pan Area | Total Tile (With 15% Waste) | Standard 12"×24" Tiles Needed |
|---|---|---|---|---|
| 36" × 36" Corner Stall | 63.0 sq ft (3 Walls) | 9.0 sq ft | 82.8 sq ft | 37 Wall Tiles + 11 Pan Sheets |

Frequently Asked Questions
How do I figure out my rise and run for stairs?
To figure out your rise and run for stairs (including sunken bath steps, raised platform tubs, or full staircases), first measure the total vertical rise from the finished lower floor to the finished upper floor in inches. Divide that total height by an ideal step riser height of 7 to 7.5 inches and round to the nearest whole number to get your total number of risers (steps). Next, divide the exact total vertical height by that whole number of risers to get your exact unit rise per step. Finally, multiply the number of treads (which is typically one less than the number of risers) by your chosen unit run (tread depth)—usually 10 to 11 inches—to find your total horizontal run.
What is the 27 rule for stair stringer dimensions?
Wait—while carpenter rules of thumb include the 24-to-25 rule (`2 × Rise + Run = 24″ to 25″`) and the 17-to-18 rule (`Rise + Run = 17″ to 18″`), the 27 rule for stair stringer dimensions refers to either the maximum 27-degree to 37-degree comfortable stair pitch angle or using a framing square where a standard 7-inch rise and 10-inch run (or 7.5-inch rise and 10.5-inch run) are laid out along the stringer while maintaining at least a minimum 3.5-inch to 5-inch throat depth on a 2×12 stringer board so the structural wood beneath the notched cutouts never splits under load.
What is the ideal rise and run ratio for stairs?
The ideal rise and run ratio for residential stairs is a 7-inch vertical rise paired with an 11-inch horizontal run (tread depth), often called the 7-11 stair rule. Under the International Residential Code (IRC), the maximum allowable riser height is 7.75 inches (7-3/4") and the minimum tread run is 10 inches (measured nose-to-nose). Keeping `Rise + Run` between 17 and 18 inches ensures a natural, ergonomic stride angle of roughly 32 degrees.
How many stairs for a 24 inch rise?
A 24-inch total vertical rise requires 3 or 4 steps (risers) depending on your preferred step height: dividing 24 inches by 3 risers gives an 8.0-inch rise per step (slightly steeper than the 7.75-inch IRC residential code max, though common on exterior decks), whereas dividing 24 inches by 4 risers produces a comfortable, code-compliant 6.0-inch rise per step (consisting of 3 lower treads plus the top landing platform).
