Shower wall recessed storage

[twodoctors]

Hi all,

Not sure whether this goes to tiling or plastering...

Getting my bathroom done starting next Monday. My wife wanted a wall recessed storage for the shower area but I thought we needed to increase the depth of the wall to do that. Looking at the net I now realise that plaster walls 100mm thick and there are "ready-made" recessed unit for sell. Looking at the pictures it "only" involves cutting an aperture on the plaster and stick this unit onto the wall, then waterproof the joint (plus probably a bit of noggins to help support it). Are these made with waterproof tile backer board (like Kerdi-Board)? Is there any reason why it can't be DIYed by my plumber? I haven't spoken to him yet but I'm one of those people who like to know a bit about the subject so I won't get conned...

Thanks.

So knowing a bit makes you able to tell if your plumber is conning you?
Why are you using him if you do not trust him?

I guess I don't quite mean that. Maybe it should read I'm a control freak and I like to know what he is doing and why he's doing it that way. Afterall I'm spending almost 5k on the room, I want it done properly and make sure it will last.

Googling the subject a bit more, it seems that's exactly what people do. Make the recess with waterproof board and waterproof it again. The wall in question needs a new plasterboard anyway so I might ask him to do just that...
