What type of drywall should be used in a bathroom?

Use moisture-resistant greenboard or cement backer board (like HardieBacker or Durock) in all wet areas and behind tile, and mold-resistant drywall on all remaining walls and ceiling.

How much extra tile is needed for bathroom layouts?

We recommend at least 15% extra tile for bathrooms because vanity cutouts, shower drains, and toilet flanges generate higher scrap percentages than open floors.
