Hi, my first post on here. I am looking at fitting thin concrete panels on my bathroom and shower wall. Has any one used them before? The ones I was looking at are either Concreate or https://livingconcrete.co.uk/concrete-panels The livingconcrete type say you can use them on a wall by fixing with tile adhesive but not much more imformation. The Concreate say they need to be glued to the wall, but does not mention if they can be fitted with tile adhesive, spacers and grout. P.s I’m not a tiler, I’m a carpenter Cheers John.
