Ditra over shower pan - TilersForums.com

Aloha everyone.

I've embarked on a bathroom remodel. I opted to use the hydro block shower pan and system. When I notched my joists and set my presloped pan, I've ended up flush with the existing wood subfloor. As such, now if I put any hardi board on top of subfloor, the transition to the pre sloped shower pan will have a 1/4" step down into the pan. I want the transition to be smoother than that so I was going to use ditra over the wood subfloor and just go right over that transition and cover the pre sloped pan as well so everything was level. Does anyone have any concerns about doing it this way? I figured if I red guard the floor into the shower and over that transition, I'm just using the ditra as a leveling underlayment. I'm just trying my best here to figure out how to make it work with what I have. Pan should have been 1/4" higher to make transition smooth, but now I have what I have. Please help

How far have you gone? Like you say the best thing is to raise the pan by 1/4” , why don’t you want to just do this?

It's already in.... pan is thinset down. Walls are in. I'd have to cut out section along pan and remove pan and get a new pan. By the time I tear it out, it will be destroyed
