Hi guys wonder if someone could help me. I had plumber come in today to fit a quadrant shower and with wall panels. I should have checked and so should he but the walles are really uneven we are talking an inch maybe more. This is the outcome in the attached photo. Plumber has left it like this and now the board is half off the wall the enclosure not even fitted to the wall due to the gap being this big. Can someone help or recommend how to sort this out? People have suggested batton fittings and even expanding foam.
