Further screeded bathroom floor issues.

[Tim Lamb]

I have been following the *concrete bathroom floor* thread with interest.

I am struggling with how to arrange a shower waste, toilet waste and a basin waste where the builders have brought the sewer connector up in a corner next to the entrance.

My vague arrangement was -basin-toilet-shower. The shower must occupy the space furthest from the door as the room is only 2.7m x 1.5m.

The waste socket is only 215mm from the entrance and not practical for directly fitting the toilet.

The floor is screed with underfloor piped heating so I am nervous about major excavations.

Cut a shallow channel for the shower waste and keep this below the toilet outlet?

Any clever ways around this?

The straightforward options are either dig a channel or raise the shower tray and box in round the room. The only other way would be to fit a drainage pump -

Probably overkill though.

What position is the entrance in?

I fitted one of those when my dad couldn't manage the stairs.

I built a shower room on a downstairs concrete floor. I put a double layer of 18 mm ply for the floor and cut channels in for the drain. There is a flow switch in the output from the mixer valve that operates the pump.

It worked fine but its not quiet, lots of sucking noises as the pump ran faster than the water from the mixer.

It didn't matter as my dad was pretty deaf by then.

The shower tray will have to be raised to make room for a trap and fall to the waste.

The idea was to put the basin where the waste is. Toilet next and the shower across the end.

Current thinking is to fit a short straight spigoted socket. Take the toilet waste across and use a 90 deg. single socket bend to connect up. This puts the sockets well below screed level!

After further thought...

How about an inverted branch *T* to join the toilet and plug the unused leg with a socket plug. The problem then is joining the 40mm shower waste to the plug.

I need a tank connector in 40mm!

Google says yes.

So the question for the cognoscenti is, would I be breaking any rules?

I don't know if it is of any use to you but the shallowest decent quality shower trap I have been able to locate is this 70 mm deep McAlpine unit
