Shower Waterproofing

Hello,

I'm doing my very first shower DIY. I've looked at a lot of video on Youtube and after watching the ones from Isaac O. he earned my trust. I learnt alot and I especially learnt not to rely on what the tiles shop tells you.

The tile shop proposed to use the full Schluter kit with unmodified thin-set. After watching the video from Isaac that "test" the Schluter system with unmodified thin-set.. I changed my mind.

So I made my own plan and I would like to know if this make sense or if there is anything I could improve.

I'm planning on using:

1) Schluter baseboard (for the slop in the shower)

2) Schluter all-set (for tiles and membranes)

3) Normal Drywall mud with the Cement boards.

4) Schluter membrane on wall and floor (even though I will be using Schluter DITRA-HEAT even in the shower)

5) Mapelastic AquaDefense on wall and floor (on top of Schluter membrane.)

Additional note:

- My walls will be cement boards.

- I will have Schluter DITRA-HEAT all over, even in the shower.

I don't really mind paying more to avoid bad surprises. Especially that I will be saving 2/3 of the cost doing it myself.

Thank you!
