Flooring Tile - Shower Tray Questions

We have an old house here in Scotland, possibly built around 1850. In the bathroom the floors are concrete and we have taken out the bath to leave only the sink unit and toilet. That leaves a square room with concrete walls and a concrete floor, and a wide open space covering approx 7 feet by four feet at the left hand end of the bathroom.

I want to build up a concrete shower tray with a drain linking into the drain for the sink unit and toilet. Then tile the tray with floor tiles and walls with wall tiles.

What is the best plan of attack here? I've been told a Granite/Cement mix will be best for the tray, but what is the ratio of Granite to Cement to Water? Can I submerge the drain (with the top flush with the tiles of course) if it is made from plastic? How do I go about the shuttering process? Are there any other considerations to take into account here?

Any help would be very much appreciated.

Many Thanks

Alex

You should buy a book on this or do a search on shower trays, alot more to it than that.:)

You will have to buy the proper 2 part clamping drain, install a preslope and liner, I would also frame out those walls to accept a vapor barrier and cementboard, which goes in next, than the final mud bed.:)

Or, you can purchase a Kerdi shower system, then all you would have to do is install their drain over a preslope of mortar and then install the Kerdi waterproofing membrane over those walls if nice and flat and floor.

Confused yet?:)

You Bet I'm confused. I don't know if Kerdi is available over here, so I think I'll bash on with my DIY idea.

Basically you are saying that there should be mucho waterproofing to consider before laying anything over the existing floors and walls. I've got the proper drain supplied by my plumber friend and he will happily connect the pies, but I'm sure he knows nothing of the foundation work involved. :o

I was under the impression that I could simply put concrete onto concrete and then tile it??!!?? :rolleyes:

Concrete isn't waterproof, only moisture resistent, you need a waterproofing of the floor and up the walls to where the backerboard will meet it. eother with the proper liner or the Kerdi system.:)

You can order the Kerdi system here.:)
