Grout Calculator

Estimate how much grout you need for a tiled area based on tile dimensions, joint width, and tile thickness, then compare costs across four grout types.

Cheapest option: Sanded at $4.50Sanded grout is best for joints wider than 1/8 inch and provides strong, durable fills. Unsanded grout is ideal for narrow joints (1/8 inch or less) and polished tiles that scratch easily. Epoxy grout is the most stain- and water-resistant but costs more and is harder to apply. Premixed grout saves time with no mixing required but is best for small to medium jobs.

This is a material estimate only. Actual grout needs vary by tile size consistency, joint depth, application method, and waste — always buy 10-15% extra and confirm measurements on site.
