Wife and I are redoing our master bathroom and she wants a tile shower with a concrete floor. We plan on using the Kerdi schluter membrane for the walls, but I'm just not 100% sure on the floor since she just wants concrete instead of tile. We will be making our own shower base as the shower is a unique size. I'm thinking that I need to use the membrane on the walls and floor and get everything properly seal. Once that is done than pour the floor and let the concrete properly cure before sealing that with some type of sealer before moving on to tiling the walls. Is my process correct or how should it be done?

We had our bathroom remodeled last year including a new shower. I wanted the Schluter system but was told there are better, less expensive systems and we're very happy with the results. So they installed a concrete floor- properly sloped and a special drywall on the walls which gets taped as usual. Then the whole shower is painted with two or three coats of membrane. So the end result is a continuous membrane, not a "sheet membrane" with joints.

We also had a heated floor installed in the rest of the bathroom so no cold feet - ever !!

So I just re-read your post ... you do not want the membrane "below" the concrete - you want the membrane on top of the concrete. Would build a pool with the pool liner on the outside of the walls ?!?!

That's what has me a little confused is the floor. I need some type of waterproofing under the concrete to the subfloor, but not sure how exactly that should be done. I can't put the membrane on top of the concrete if she wants the floor to be finished concrete.

Best to locate drain, tar paper floor and walls, grout shaped to drain, manufactured liner system of choice up walls and over curb and a wire reinforced conc floor with proper curbed pan. I'd recommend getting the wire reinforcement epoxy coated. The walls can be mortar or pre-manufactured with tile and grout.I'd recommend caulking all the corners where wall meets wall or wall meets floor rather than grouting. Appropriate grout matching sealants should be available where you buy the grout.
Use tar paper on floors and walls to create a "cleavage" layer that allows the shower components to "move".

If you do a traditional concrete shower pan, it will be poured in two stages. The initial concrete pour on top of the sub-floor will have a slight pitch toward the drain Then the thick heavy rubber pan liner gets laid down on top of the first layer of concrete, and gets sandwiched into the floor strainer. Finally the second layer of concrete on top of the liner has a slightly steeper slope to the drain.

Then the wall membrane comes down and overlaps the top edge of the rubber pan liner, so any water that runs down the wall ends up inside the pan liner.

IMO, you are asking for trouble down the road, find a good shower floor tile that she can live with and use the money saved on upgrades to something somewhere else in the house.

I have used the Kerdi system a couple of times with very good results.

I lined a shower and an entire bathroom floor and 4 inches up the wall all the way around. I used the Schluter shower pan and curb as well as the Ditra on the floor as well. I was very happy with the results.

The system worked great with no leaks.

Just, whatever you do, make sure you follow the instruction TO THE LETTER! And, I didn't specify this last time I told someone to use this stuff, make sure that you put it on over a moisture resistant surface (green board, cement board, moisture resistant sheetrock, etc.). If you apply it over regular sheetrock, it''ll peel off and take the paper backing with it.

We just used one of these in ours so that we could get to a level entry without a curb. Grout should be going in today. We used a 48 x 48 cut down to our size of about 46 x 46. Dang shower pan was about $750 though. Reviews are good - hope it works!

Y'all need to go reread what he's asking.

He want the Concrete to be the floor. As in that's what you will be standing on when showering. Can't put a membrane atop that.

I read it. Also, This is what I did for 32 years.
A membrane under it going up will but the Cement will take time to dry always.
If he does this his Cement Floor will aways be wet to some extent.
In would also run as I did in my own home run a Membrane Behind the cement board walls I used USG 1/2. screwed with Epoxy Deck.
Floated all seams and taped floated them and used a commercial flexible mortar that was also used to set the tile.
100% of all 4 walls even in my guest bats are done this way even with tubs.

Nice work, 340. DO you use some kind of tile spacing/leveling system, or do you just eyeball it?

I used to eyeball it, but I've been looking at the Raimondi (or similar) tile leveling system (like THIS) for my next job (I don't do this for a living). Do you have any experience with it?

Those will be fine but keep in mind that no material is 100% Stone as well as Porcelain and Ceramic so some synthetic or wood wedges will be needed as well.
When It comes down to it a Tape Measure and Level Pencils are ya best friend. Along with String.

I found that if installing an accent band or feature in a design it worked best to install that item from a stringer...wood/metal...whatever...and then cut the corresponding tile as an infill to

complete the wall...

It worked well for this...everything stays laser straight...

Sorry Doc...

We'll try again in 2 years...up

Edited...Looks like it will be 6 years...biggrin

I get that. I've put down a lot of ceramic and porcelain, but when it comes to stone (or hand-cut tile), I hand it over to my wife, who can lay tile much better than I can and can eyeball grout joints and tile level like a pro. All the stuff I've done has been learned through experience (i.e. stupid mistakes) like my first tile job...a 12 x 15 kitchen in an old house. I decided the best idea was lay the tile against the wall first and work my way in! I'm figuring you can guess how THAT worked out.
