Layers of a Bathroom Floor


Would you please confirm this to be the proper series / sequence of bathroom layers going from joist to tiled flooring:

- 3/4" plywood (construction-adhesive taped to joist)

- 1/2" plywood (type BC, staggered, screwed to 3/4" plywood: 4" perimeter, 6-8" field using 2.5" galvanized)

- mortar bed

- 1/2" sheetrock (screwed to plywood: 4" perimeter, 6-8" field using 2.5" galvanized)

- (electric floor heating, if applicable)

- mortar bed

- tile

Thank you.

Something ain't right about this.
I'm no tile person and know this is wrong.

It's not tape, it's adhesive in a tube. I'd suggest using 3/4" T & G Advantec subflooring instead

- 1/2" plywood (type BC, staggered, screwed to 3/4" plywood: 4" perimeter, 6-8" field using 2.5" galvanized)

Use 1/2 Subfloor rated plywood. it will say right on the panels.
Use ceramic coated decking screws instead, there not going to rust off and almost never snap off or round off while installing.
- mortar bed

- 1/2" sheetrock (screwed to plywood: 4" perimeter, 6-8" field using 2.5" galvanized)

Sheetrock in any form is never used on a floor.
- (electric floor heating, if applicable)

- mortar bed

- tile

Thanks.
Are you sure you do not want to hire this one out?
