What this thinset calculator calculates
A 120 ft² bathroom at 10% waste requires 132 ft² of planned coverage before the product bag is selected.
Formula
Tiled area × coverage allowance ÷ product bag coverage = bags, rounded up.
Worked example
For a 120 ft² floor and 10% waste, plan on 132 ft². Divide by the current bag's coverage for the chosen trowel, then round up.
Ordering decision
Large-format tile, membranes, back-buttering, and substrate flatness can increase mortar use.

Thinset mortar for tiled area
This thinset calculator estimates mortar from tiled area, trowel coverage, substrate, and waste. The trowel notch and tile back determine the applied bed.
Limits and professional review
Measurements, product yield, waste, moisture, and site conditions can change the order quantity. Local code and a licensed professional govern structural and electrical work.
