We have remodelled our bathroom and hit a problem when we realised that the wall is too uneven for the bath to sit flush. This is an issue for tiling.
Our current thought is to build out the wall in the low spots with plaster and also double back buttering if needed. The tiles are a mosaic finger tile so should be ok with a bit of unevenness.
But what to do at the edge? It will have different thicknesses of glue. Is there any tile option that can change in thickness?
