Pocster Posted April 10, 2019 Share Posted April 10, 2019 Right ! It’s complicated ! Doing the ufh prep in the bathroom . How thick does the wall need to be to take a geberit hidden flush cistern ? Because we don’t know the exact size of our shower tray nor the bath type ( as in where the waste is or where the taps are ) i’m going to shutter out those areas so they have no ufh nor screed ; same for inner geberit wall . This a sensible plan given the situation? cheers Link to comment Share on other sites More sharing options...
Pocster Posted April 10, 2019 Author Share Posted April 10, 2019 Equation of faith goes like this : want bathroom + dont know exactly what suite + dont know what shower x not really sure how this is going to go / wife-factor Lots of variables not many constants ... 1 Link to comment Share on other sites More sharing options...

Onoff Posted April 10, 2019 Share Posted April 10, 2019 My two frames were a bargain £100 the pair. Older models so deeper but work a treat. Geberit instructions are good too. I was lucky in the frame was sited over the old blocked up doorway that ended up 2" lower anyway than the main wall. Over a 3m wide wall not one stud is the same depth range from 90mm to I think 145mm. In part to square the room off and also to allow depth for the pockets as well as wc frame. The studs are concrete screwed to the wall at 5 points minimum. The rears are packed with timber where the screws are then everything foam filled. Geberit instructions are good too. Typical drawings: There'll also likely be a video for whatever frame you get, e.g: 1 Link to comment Share on other sites More sharing options...
divorcingjack Posted April 11, 2019 Share Posted April 11, 2019 Just be aware that the slimmer cisterns are more expensive, generally and are not compatible with all the flush plates, so if you're keeping an eye out for a bargain then it narrows your options somewhat. I got good deals on the grohe frames ((duofix), so they are maybe worth a look too - still very solid looking. Some of the air flush plates are £300!! But there are loads on eBay and gumtree, so if you know what range will fit the frame, you can make some savings there. 1 Link to comment Share on other sites More sharing options...

ToughButterCup Posted April 11, 2019 Share Posted April 11, 2019 Geberit are driving me mad at the moment. So I am very grateful for this thread. They make the purchase process so difficult; it's almost as if they don't want to sell their products. If only their sales effort was as strong as their production and support.

Pocster Posted April 23, 2019 Author Share Posted April 23, 2019 So 100mm wall depth does that allow for the waste ? ( if say was straight down through the floor ) Link to comment Share on other sites More sharing options...

The video is for a Sigma. This should really help. Full instruction leaflets are here for the Sigma, Omega and Kappa cisterns (not my ones as older and although 15cm Kappa cisterns they're 98cm high frames): https://www.geberit.co.uk/products/installation-systems/geberit-duofix/ 1 Link to comment Share on other sites More sharing options...
Onoff Posted April 24, 2019 Share Posted April 24, 2019 Your cheapest route at the mo for a Geberit frame is to get a 111.292.00.1 like I have and as per the email but that calls for a stud depth of 170mm. (I'm lucky in that everywhere mine have gone/are planned I can make depth without too much detriment on room size. In the bathroom it went back into a deep studded wall & old, blocked up doorway. In the ensuite it'll go into a dormer cheek / the loft. The downstairs cloak is the only place I'll lose a bit of space but I can move a door frame to grab some back).

I am committed now to 100mm!. I've shuttered this amount away from my UFH - so that's the deal ? Link to comment Share on other sites More sharing options...
