Yep was planning on using proper adhesive. I had genuinely not thought of going up to 25mm but that seems like a good shout if I can get it up here. I don't mind paying more, it does depend on whether I can actually get the right grade up here. I will definitely see if I can get 25mm was that marine ply or WBP? I'm installing it myself. A slower and probably over-engineered job but after deciding to pay trades to put in the en suite, I'm just not willing. Fortunately I have none! I will be getting a strong man to hoik them up the stairs and help me though, whether it's 18mm or 25mm Thank you everyone for the brilliant help and feedback. I'm going to go with ply and will try to get the 25mm. If I can only get 18mm I'll pack out between the studs in the general area.

Hi Temp, thanks for responding. I would hope to hit brick behind whatever I use, but the bricks in the room below are kind of honeycomb (it's an old house). I wouldn't trust them to take weight. This is why I thought WBP ply at 18mm. I don't know how structurally sound Hardie board is if it has drill holes fairly close together because I've never used it. I mean plasterboard wouldn't take it.

Hello, long time lurker and kinda first time poster looking for advice on bathroom planning. TL;DR: Will tile backer board fixed over brickwork hold grab rails or is WBP better? My bathroom currently has been lined with plywood and then tiled. I am looking to remove the tiles and reconfigure so I have a larger shower and a Japanese style sit bath. The shower and bath will run along an internal party wall which might be brick (assuming it is the same as in the kitchen. Previously the original lime plaster was chopped out and at least half the wall replaced with ply and then tiled over. The other end of the wall looks like it might be plasterboard. As this wall is where the shower (with concealed piping) and bath will be, it is going to be tiled to about a foot above the shower head (ceilings are 3.4m) and the shower opening will be at one end of the bathroom, with the bath accessed via steps built into the other end of the shower. These steps will create a shower seat as well. I want to attach a couple of really strong grab rails at the transition between shower and bath. I'm not convinced that tile backing boards are up to the job of holding a grab rail and I'm not sure where the rail will go to put studs in place. I can drill all the way through to the brickwork, but if I hit mortar, then I'm not convinced that is going to be safe. Whatever I use, I plan on completely tanking the shower/bath area. I have attached a rough plan but it's not to scale and I struggle toggling this kind of stuff. For the record the bath is 100cm high and I have checked I can get a Gerberit wall cistern in there which will service a washlet.

As a massive fan of mid-century style, this post needs photos!

Hello there, I’m joining in the hopes of getting some guidance on building a garden annex/workshop using sips. Nice to see a big Scottish contingent here!
