How do you know which type of grout is the correct one to use? Specifically for a tile floor in a shower?
I have read on different websites conflicting ideas on which to use. The type I currently have in my shower (and is deteriorating) is non-sanded. When I re-grout this floor, should I use sanded grout? What are the pros and cons?
The tile is the two inch square tile that came pre-attached together in a square sheet.
