Square footage calculation for shower tile involves measuring all wall surfaces to be tiled and adding a waste factor to account for cuts, breakage, and future repairs. This ensures you purchase enough tile for your project.
The calculator uses the formula:
Where:
Explanation: The calculation sums all wall areas and adds a percentage buffer to ensure you have enough tile to complete the project.
Details: Accurate square footage calculation prevents purchasing too much or too little tile, saves money, and ensures you have matching tiles for future repairs.
Tips: Measure each wall's height and width, calculate area (height × width), and enter all values in square feet. Include a waste factor of 10-15% for typical projects.
Q1: How do I measure irregularly shaped showers?
A: Break down irregular shapes into rectangles, calculate each area separately, then sum them together.
Q2: What waste percentage should I use?
A: For simple layouts use 10%, for complex patterns or many cuts use 15-20%.
Q3: Should I include the shower floor?
A: This calculator is for wall tiles only. Floor area should be calculated separately.
Q4: How do I account for windows or niches?
A: Calculate their area and subtract from the total, but still include them in your waste factor.
Q5: Should I buy extra tile for future repairs?
A: Yes, it's recommended to keep 5-10% of your tiles for future repairs as tile colors may vary between production runs.
