I've been to look at two job's this evening, both have been done by local people. One was a plumber, the plumbing looked fine but his tiling was just about the worst i've seen. The customer wouldn't let me take any pics for myself. Shame. But the other one was a bathroom company who has a good reputation sells and installs them. It's been in for only six months and it looks as though it's been leaking from day one, I asked the guy about the prep work, boards, tanking etc, showed him pics of said tanking and his reply won't shock anyone. They never did any of that they just put them on the bare wall. The first one i have booked in for a re-fit and the second one looks likely to follow. All good for me but not the sort of work i want if i'm honest.
