Questions - New bathroom project - TilersForums.co.uk | Tile Forums

Chrisfaefrance · 25-03-2007

Right this is the project I’ve signed up to do, I’m just a DIYer and haven’t got great experience in the building trade, but I like a challenge

. Anyway, any advice or suggestions would be welcome.

I’ve had to completely gut an old bathroom i..e. rip out the bath, sink, toilet seat, old tiles (wall and floor) etc. All of that is done, with the exception of the toilet seat. (for the moment).

Got a plaster in to skim the brick walls, so that’s done too now and looking good.

The bathroom is 2.5m x 2m.

I want to put a corner shower in (instead of a bath), so the first problem is the height of the waste-water evacuation pipe. The top of this is 13cm off the ground. The base of the shower tray obviously has to be higher than this.

Rather than build the base of the shower up directly to this height, I’m considering raising the floor by a few centimetres first. There are two reasons for this:-

The shower base won’t look exaggeratedly high off the floor.
I could run the radiator supply pipes underneath the false floor in order to provide some floor heating. I’ve got to plumb-in a wall radiator and so need to take the plumbing across the room in any case, so this might be a decent option….though I’m not sure if this could present problems. Anyone ever do this before ?

Is it ok to put floor tiles directly on to chipboard flooring ? What thickness chipboard ?

As for the tiles, well the ones I’ve been looking at can be used on both the floor and the wall and seem quite heavy. Does this extra weight mean they’ll be more difficult to put on the walls ? Do I need to do use special adhesive (or thicker adhesive) ?

I got tonnes of questions, but I guess this lot is already enough for tonight !

Forget the radiator - go for water piped underfloor heating.

Easy to install and adds a lot of value to your house, as well as more economical heating than standard rads and electric UFH.

If you are going to raise your floor, you have to consider the step that will be created from room to room.

Could do with a picture of your water waste to give a perfect tip and what to do.

Tiling on top of wood is possible after priming the surface first, and then using a flexible adhesive and flexible grout. But i imagine the potential movement from the raised floor will be quite considerable, so I dont think this is a good idea.

What's stopping you sinking the trap to the new shower in the floor again?

High PHT.
Well the "radiator" is to be one of those flash chrome towel heaters, so it's more of a feature than just bing functional....so I think I'm going to be stuck with that, otherwise I'd just use the underfloor water heating.

Yes, the hall to bathroom step is definitely not wanted, but I don't see any other solution for the moment, so I'm just going to have to live with that.

I don't have any pics of the waste pipe, but there doesn't seem to be a great deal of choice. It's just a grey plastic pipe going from behind the bath to the outside (I think).

Are you saying I shouldn't tile on the raised floor because of potential movement ?
