Bathroom steps for completion

So we have a clean slate on a small master bath that will end up with a toilet, 48 x 48 shower and vanity. The 2 corner walls of the shower have been walled with hardibacker. This is a 60's home and the old floor has been removed with its built up mud and we are now on slab, not a builtup base.


We want to do the shower in kerdi so to proceed, do these steps sound correct:

1.) break out slab around old drain to connect fernco and new pvc extension for kerdi drain;

2.) cement in hole around fernco and new PVC extension;

3.) build sub floor up on slab including shower? or do we ignore the shower area and just build to include the curb? or dont include curb?
(what to build this up with?)

4.) build curbs on top of new sub floor or what is decided in 3 above.(suggestions for materials to build the curbs?)

5.) build shower floor, install kerdi drain (kerdi kit or suggestions)

6.) apply kerdi fabric to all walls, floor and curbs

7.) apply ditra to new sub floor outside of curb (thermal break for floor heating and flex for foundation movement?)

9.) install heating wire on top of ditra embedding in thinset for porcelain tile

10.) tile shower walls

11.) tile shower floor

12.) grout

13.) install toilet with flange being mounted on top of new tile, with holes drilled through tile, sub floor and foundation for support?


How does this sound?

OK, let me see if i can answer a few of your questions. But first. Have you ever built a tiled shower? Have you read the kerdi installation manual? Any previous experience? Do you have lots of time to complete this?

1. Of course.

2. NO. Depending on method, the Kerdi drain does partially into the hole.

3. I have no idea what you mean. How will the shower floor be built? Deck mud or Kerdi foam pan?

4. See #3.

5. See #3, Deck mud or Kerdi pan, witch one?

6. Good idea.

7. Subfloor, what subfloor? I thought your floor is a slab?

8. There is no eight.

9. No, Warming wires go under Ditra.

No, have the kerdi manual and no experience other than a foyer that was about 8x8. Yes, lots of time.


3.) to be level with the adjoining bedroom, the bath is about 3/4 of an inch lower. My question here was meant to mean do I build up this 1 inch, including the shower or just the floor and ignore the shower area? I am thinking with the porcelain tile, ditra and heating wire, along with thinset, the 3/4th of an inch is irrelevant.

4.) I think I should put in temp curbs, do the floor of the room and toilet and the cirbs will rest on the original slab, correct?

5.) Kerdi kit


I think you have given me some answers to get me going.

well just determined that my 2 shower walls are not totally square to each other. Is there any acceptable variance in this?

Using the triangle method 3 x 4 x 5, looks like maybe a 1/2 inch??????

Makes no difference for the walls, but remember that when you do the floor.

Ok, that is very good news. Regarding the floor especially the shower floor, is there a tip for this? or just remember to cut the tile accordingly?


In this case, will it matter (appearance) if the floor is down then walls overlap versus walls down and floor to it?

Thanks

Floor down, walls over for most finished look. Have you outlined your intended procedures on the build of the shower floor, drain, membrane, etc. ?

Thanks, yes I am either going to use a Schluter kit or USG kit, have not decided yet which one. Going to stack bricks for the curb.

Kerdi on the walls, with lots of questions here I am sure.
