Hi All, So I stripped out my old bathroom with all good intentions of trying a DIY bathroom refurb. i managed to chase in the new shower pipes and alter the plumbing for the new bath , which I have sighted see photos. Now i think my walls are slightly out which has put me in a dilemma for the tiling. The left side (I think) will be okay once i’ve applied adhesive and eventually sealed that there isnt a gap between the bath and the tiles and it kind of ‘sits’ however the right side appears more of an issue. Whats the best way before tiling to try and sort this gap and wall to allow me to tile without there being issues? Cheers!
