New Ensuite Layout Idea Problems

[v12sv8]

Hi all

I've been lurking for a while and using various existing threads to help me rip out my existing ensuite and for other minor DIY tasks. Previous ensuite had rotten floor due to leaks and the entire floor squeaked due to chipboard being nailed to joists - the squeaking even went to the hall as the chipboard floor went from the hall to the ensuite. So thanks for the knowledge found on this forum as I've fixed the squeaking floor and managed to remove the entire bathroom myself which has obviously saved a lot of cost!

Anyway...

I'm now down to just to just a shell of a room, and rather than put everything back in the same place, I want to rearrange things so I can have a bigger (and walk-in) shower! I've measured everything out and used wooden batons and floor protectors to template everything and it all seems like it'll work.

My only problem now appears to be whether I can reroute the plumbing properly.

Below is a diagram of what I'm planning, and a picture of how the room currently looks.

The biggest problem I can see is: How can I run the new sink waste pipe to the existing soil stack? Ideally I don't want to run it along the left-hand and back wall as I think I'd lose room space by having to box-in the walls slightly to allow room for the 32mm sink waste pipe. But I also can't see how I can run it under the floor especially with the copper pipes running directly thru the room (circled in red)

Any ideas gratefully received, also if there's any other potential problems or advice anyone could give me I would be very grateful.
thanks in advance!

32mm pipe could be routed through those studs (if they're 3 inch and it bothers you that you'd have ~16mm of stud left either side, drill your holes 10mm nearer the room than centre and line the stud with a glued n screwed 19mm batten - you won't notice the 20mm loss of room space), but how big of a sink do you need? Have you looked at combined sink/toilet units?

It may be possible to move your pipes (they're slimmer, easier to drill and route through studs) and deepen the notches for your waste if you'd prefer the waste under the floor

You can also get corner toilets and corner sinks, and if your room was a wet room it could have a toilet in one corner, sink the other (or combined toilet sink) and a shower head in the room centre. A sink/toilet would cope with getting splashed wet from a shower

You appear to have wiring not in a safe zone; that should be addressed

Insulate your block wall

Run it through the battens, use solvent weld waste and test before covering over.

Yes have looked at combined sink / toilets, it wouldn't be my choice if I could have a proper sink next to the radiator

Wiring - is that on the back wall by the shower water feed? I did wonder about that but it's always been there so thought it was OK....

And can the new waste pipe go underneath the existing copper water pipes?

The picture isn't great, it looks like you have a wire coming up behind a socket box and going diagonally across the wall

And can the new waste pipe go underneath the existing copper water pipes?

Perhaps you misunderstand; both I and Hugh proposed to run the waste pipe inside the stud wall

Drill a 34mm hole through your timbers with a slight fall, stud to stud, and route the pipework through it

If getting the pipework into the holes that you drill through stud centres is too hard, notch the studs out 32mm, run the pipes , then run a glued n screwed batten up the stud to encase the pipe and restore structural rigidity to the wall

Red-wall stud with 32mm notch and pipe installed
Green-D4 urethane glue
Purple-new batten eg 25x50
Black-screws at eg 250mm spacing

Thanks so much for your advice! Sorry, yes I did misunderstand!

You are right, there is a wire coming up from behind the socket and running across the wall. I will sort that as you are right, it's not safe.

I'll try to follow the advice given and research more into how to run the waste pipe. thank you - as it tells me theoretically I can have the sink where I want which is good news! thanks!

I would redesign to eliminate the problem , turn loo 90%, put sink next to it on right hand wall , and switch shower panel side . Gives you room to dry yourself without obstruction and puts all plumbing on one side .You might also get door opening in back to rad , if there is room.

 

[robinbanks]

You might also get door opening in

Why would you want a door to open into a small room? The sweep of a hinged door is such a waste of space; it should be done into the room that can best afford it

Don’t know about you but I always close the bathroom door.

 

[robinbanks]

Ah yes, you're right; doors that open out only swing once

I have an ensuite that is about 1.6m x 1.7m with a door that opens inwards. Facing you as you open the door is a 900 quad shower cubicle. To its left is the WC, then in the other corner is the pedestal basin and the heated towel rail.

Great idea and if I could do that I would, unfortunately there's a window on the right hand side wall - so it's not possible sadly

Apologies for confusion, the door opens out to the bedroom, not in to the ensuite

My query was to foxhole. I agree with the plans as drawn, that the door of such a small room should open into the larger room

Yeah, crazy. It would make the space much more usable if it opened the other way

How would window prevent it? (My loo and sink are both under a window .)
