Tool-first calculator

Bathroom tile calculator: sqft, grout, and thinset.

Enter floor and wall dimensions to estimate total tile area, number of tiles, grout buckets, thinset bags, and a broad material cost. The calculator uses editable assumptions because tile waste, pattern complexity, and substrate prep vary by job.

How to use this result
  • Buy tile in full boxes. Check the box for sqft coverage and round up to whole boxes.
  • Mosaics and small format tiles need more thinset coverage per sqft than large format. Add a bag if in doubt.
  • Material cost above is DIY only (tile + grout + thinset). Local installed cost below covers labor, prep, waterproofing, trim, and supplies as part of a typical bathroom remodel scope.
