Back to Wall Toilet and Concealed Cistern - Framing and Adjustable wall

[pauls142]

Hi,

I am about to fit a back to wall toilet in my cloakroom and remember when I had this done some time ago the fitter created a wall that only had a lid (to access the top of the concealed cistern). I would like to do a more future maintenance friendly job myself on this new project and am quite competent at DIY and plumbing etc.

I am planning on using 9mm exterior ply for the wall (and then painting it to match the other walls, I already have some of the existing skirting to finish the bottom. Planning on using something like a kitchen worktop (cut to about 280mm depth) for the lid.

I have a width about 900mm (main wall to main wall) and the height of the false wall will be about 900-1000mm (to give a sufficient head on the drop pipe for a good flush). this means that reaching fixings on the floor inside the false wall will be difficult.

I would like the front of the wall to be free of visible bolts, covers, etc. but be (fairly) easily removable in case of maintenance of the soil pipe or a leak in the inlet (i.e. not hidden screws filled and painted over like the last job I had done). I would really like a method of fixing the board flush up against the back of the pan from the inside that is adjustable to allow a good fit to the pan but also be firmly fixed at the bottom, top and sides so there is no movement if it is knocked etc. but at the same time have a good method to be able to release the wall, push/slide it back 2-3mm off the pan and then lift it up and out of the way. I appreciate that I will break the filler seal at the edges of the wall when I do this but hopefully that will just require a little refilling at the end and a touch up of paint.

can anyone suggest a fixing method or am is wishing for something that cannot be easily achieved (at a sensible cost). I was thinking that simple angle brackets fixed to each main wall but how to reach the lower brackets for dismantling is my quandry. I guess I could use wing nuts at the bottom and was even thinking of a pair of plastic adjustable plinth feet to make the area around the back of the pan nice and snug....



Any help and advice greatly appreciated

Thanks
Paul

Use a Geberit cistern/ frame, no top access required.

Yes geberit are quality. You can access everything from the front panel.
You might want to leave access to the float valve connection though. I fitted 4 in a property once and the joiner and tiler concealed the lot.

That was 12 years ago and I was back a few weeks ago doing various maintenance jobs and these units are still going strong with a large family in the property.

Thanks gents. the issue for me though is to have access to the bottom of the stack on the pan in case of adjustment/leaks and also access to the inlet pipe for same reason. Maybe I'm just being a bit paranoid Anyway, I already have the pan and cistern so The Geberit is not an option. I was really just looking at a good way to make the wall "easily" dismantle-able while being invisible from screws etc from he outside and being secure and firm against the joint to to the pan and side walls. Don't have much experience of stud wall framing and even less for removable walls so the type and method of fixing the wall is what I really need.

Thanks
Paul

Wide range of keku fixings allow removable panel, though should not be required as if it leaks you won't know to until it's rotten by which time it will need complete replacement. Just fitted mine and left top access only, if it fails I kept a few spare tiles which would allow me to cut access and make good

Thats a very good point (about the leak will necessitate a replacement panel anyway). Perhaps I have been overthinking things a bit
