Shower build question not sure wher to ask
 
Total gut and bath remodel. In the shower, is it ok and acceptable to just use 1/2 inch hardie backer? Over studs?

Going to use the Kerdie process for completion.

Re: Shower Build
 
Hi DP

On the shower walls yes. On the shower floor, NO!

I am in the final stretch of doing a total demo and rebuild and used HB 500 as my substrate. As long as your framing is sound, straight and level 2x4's with a maximum 16" space from center on your studs, you'll be fine. Make sure your framing has adequate corners to attach the HB too. Leave a 1/4" seam at the base and a min 1/8" on the seams.

Also since you are using Kerdie, don't put a vapor barrier behind the HB as you will just trap moisture in your wall. The Kerdie is waterproof and considered a topical Vapor Barrier.

HB is a pain to cut. You have to score the hell out of it with a carbide tip cutter and snap it towards you. The snapped surface looks like a topographical map of the Sierra's and will require sanding for a flush fit. If you take a saw to it. One it will eat up normal blades and two, the dust it creates is volcanic and dangerous (Silica)

Had I known then what I know now i'd have gone with

I'm just an avid DIYer with about 10 successful projects under my belt. So let's see if the pro's have a different opinion.

Good Luck

you can do it without kerdi...

vapor barrier + 1/2" hb on studs (walls) & fiberglass pan, or traditional mud/tile pan

Sure he could, but, he wants a higher quality shower than the old traditional ones. One that is completely waterproof, both floor and walls, with vapor barrier. Because of the surface membrane it'll dry quickly between uses therefore will look better after many years of use.
