Tiling a bathroom requires careful planning to avoid overbuying or running short on tiles. The Bathroom Tile Calculator is a practical tool for homeowners, contractors, and DIY enthusiasts to estimate the number of tiles needed for floors, walls, or shower areas.
How the Bathroom Tile Calculator Works
The calculator uses basic area calculations:
- Enter Area Dimensions – Input the length and width of the floor or wall in feet or inches.
- Enter Tile Size – Provide the length and width of the tile.
- Include Waste Factor – Add 5–10% extra for cutting, breakage, or pattern alignment.
- Click Calculate – Receive the total number of tiles needed for your project.
Formula for Calculating Bathroom Tiles
The general formula:
Number of Tiles = (Surface Area ÷ Tile Area) × (1 + Waste Factor)
Where:
- Surface Area = Length × Width of the floor or wall
- Tile Area = Length × Width of a single tile
- Waste Factor = Extra tiles for cutting, breakage, and alignment (usually 5–10%)
Example Calculation
Suppose you have a floor area of 8 ft × 10 ft and tiles measuring 1 ft × 1 ft (12 in × 12 in):
Step 1: Calculate Floor Area
8 × 10 = 80 sq.ft
Step 2: Calculate Tile Area
1 × 1 = 1 sq.ft
Step 3: Base Tile Requirement
80 ÷ 1 = 80 tiles
Step 4: Add Waste Factor (10%)
80 × 1.10 = 88 tiles
You will need approximately 88 tiles to cover the bathroom floor.
