Looking for some help, feeling like this project is growing rapidly!

100 year old house, doing a partial bathroom remodel. The shower and walls are in good condition. The floor was a cheap glue down laminate tile that I pulled up. Underneath is a 3/4"+ (maybe 1"?) plywood subfloor over the top of the original subfloor. In spots the last install used leveling compound, some of this broke and pulled up with the tiles. The floor slopes down to one corner by 3/4" over 3 feet, you can see this in the shower picture. My question is this- what do I use between my Ditra and the current floor?

Looking underneath it, the shower is supported on the one end by another sub-base, under that is the 3/4" subfloor.
I don't know if leveling compound will hold to the plywood, the previous layer came up with the tile in some spots, including in the low corner
The subfloor continues into a neighboring room and is tiled over in there, so removing it will be quite complicated.

Please help with some way of getting tile on this floor!

You could put a 1/2" piece plywood over existing subfloor, then leveling compound, then ditra.

I'm in the process of remodeling my bathroom as well in my 100+ year old house and the floors sagged quite a bit as well. My bathroom is longer than it is wide so I ended up cutting tapered "sleepers" to bring it back up to level and put T&G subfloor over that. In your case SLC will probably be the best repair. That was my first choice but the amount I would have had to use to bring the whole floor up to level would have been a crazy amount of weight localized on only a handful of floor joists.

With the 3/4" plywood plus the "sleepers" it brought my whole floor up a little over an inch. Crazy amount of work but walking on it now there is no way I could have left it alone. Night and day difference!

Good luck! Working with old homes is always a project in itself no matter how easy your initial project is:biggrin2:

Apguy, can you expand on "sleepers"? I need to do some leveling of my subfloor for a laminate install and am trying to get ideas on how to approach it. Sorry, don't mean to highjack the thread
