Kerdi questions, membrane vs. board

I will be tackling my own alcove shower project in the next month or so. From what I have read the Kerdi Schluter system seems like a good choice. My question is if there is a big advantage to using the Kerdi board over hanging moisture resistant drywall and then using the membrane? If it matters the shower will be 42" x 48" and I plan on using their shower pan kit.
Thanks

Hi Nic, Welcome aboard.

Either method is good. The advantage of the board is that it saves work and time. It'll cost a little more than using membrane and drywall.

If you do use drywall, use the regular wall board, not moisture resistant.

Newb Kerdi shower pan tiling question?

I'm wanting to use the Kerdi Shower ST prefabricated pan. My question is if the pan is sloped on 4 different planes how do you tile at the transition areas from one slope to the next? Must you cut all tiles so that the intersection between the slope changes is one long grout line? I hope that question makes sense.

Nic, let's keep all questions related to this project on this thread so that the history is in one place, and questions and answers aren't duplicated.

It's been some time since I worked with the tray, so I don't specifically remember seeing any visible lines running from the drain hole to the corners.

But if there are, you wouldn't need to cut the tile at those places. The size of the tile 4x4 or smaller) will form to the "bowl-shaped" floor easy enough. It's one of the reasons for using the smaller tile. Larger tile can't cover the slope properly.

The transition isn't that noticeable (particularly on a larger shower like that). As long as you're using smallish tile, you don't need to do anything.

On the kerdi-board vs membrane, I just finished a kerdiboard + kerdi shower pan shower. The board goes up fast, but honestly I spent an awful lot of time putting up kerdi-band. The membrane is a little bit tricky---I didn't get it perfectly smooth on the shower pan. Probably would have been better if I had been doing membrane on the walls for practice.

If I had to do it again, I think I would go with a traditional shower pan with a liquid membrane. Fewer steps and issues with overlap, etc...

Nicpaige as a novice who did this at my sons home, I did kerdi over cement board. Had I known what I later learned here long after putting up the cement board, I would have used the kerdi board. While the efforts to cover the cement board were uneventful, it would be so much easier to use the kerdi board.

The next bath, tub surround, will be done with kerdi board.

Cost aside, I prefer drywall and kerdi. Once you apply kerdi band to the seams of kerdi board and four inch patches on the screw penetrations, you will find not much board is left exposed anyways.

I would suggest the 8'x4' kerdi board. I feel it's better in just about every way for a homeowner.
The kerdi board will not self destruct like drywall if it were to get wet.

Travis, that is a very good idea!

We started when kerdi fabric was the only choice

When kerdi board came out we switched immediately

When Laticrete HydroBan Board came out we switched immediately. HBB is 3 waterproof layers and is much stiffer.

And i believe that hydroban board is less expensive.

I suppose you'd have to define "better". I suspect Schluter and perhaps Wedi spawned almost all of the membranes and foam boards. Waterproof is waterproof, not measured in degrees except when it comes to vapor permeability, which is of no consequence in a conventional shower.

Better might simply be easier to find or less expensive.

How do you finish the seam between the Kerdi board and drywall above it? Tape and mud?
