Bathroom Floor Backerboard

Finally, something went smoothly!

Going through the trouble of laying two sheets of plywood for the subfloor made us comfortable laying 1/4" backerboard. Despite my hatred of the 1/2" Hardibacker, I decided to give the 1/4" stuff a try. It was sooooo much easier to work with. Lightweight and easy to score and break on a straight edge. After getting the toilet discharge and water intake holes cut in the proper place, the rest was easy.

Melissa mixed up the dryset thinset (I think that's what it's called), spread it on the subfloor, and I layed each cut backerboard in place, leaving 1/8" gaps around edges. The Hardibacker screws were available with square head drivers and they went in like dreams. No stripping like the Philips head wall screws Lowes carried. Now it's ready for some tile!

Then we can finally tile the shower curb. Despite the fact that every DIY site fails to say so, logically, it seems better to do the bathroom floor before the shower curb so water running down the curb will land of the floor tile rather than a grout line or silicone bead.
