Hello I’m not sure if I’m posting in the right place but I could do with some advice regarding our newly installed bathroom (6 months old.) I’ve just noticed stains in our dining room Ceiling directly below our shower. My first thought was leaky pipe work but I’ve just spent ages inspecting everything and have found: -Bubbling paint all down the dining room wall which indicates this has been going on for some time, -cracks and holes in the grout all over the place in the shower cubicle, -gaps between the shower tray/sealant, which I imagine is what’s causing the leak. Now I need to know what I should expect from our bathroom fitters. Should they fix the grout, reseal for free, should they also fix the downstairs room? Should we suck it up and sort it ourselves? Is it normal for gaps and holes to form? As a side note the wall tiles were fixed using dot and dab which I questioned at the time but he seemed confident and said it needed to be dot and dabbed due to uneven Walls (despite them fully boarding and plastering). Will add pictures if possible. Thank you.
