Hi,
I’m about to embark on a bathroom tile job. Some years ago I tiled one bath floor over a combined one inch of plywood. It’s been about 10 years and no problems using 8 X 8″ tile.
Now I’m doing the master bath with the same sub floor and same size tile. I’m considering 1/4″ hardiboard over the plywood and would rather use it instead of cement board as it appears more user friendly, i.e., easier to cut.
In addition I intend to run about 24″ of tile above a jacuzzi tub on the walls surrounding it. The walls have green board. Am thinking it might be a good idea to use hardboard or cement board here as well. The tub is seldom used and 24″ seems about right to deflect any splashing.
Would appreciate comments from those with more experience and knowledge on the subject then this old diyer.
Chuck
