"Only 2* sorry Tesco but, the discolouration of the grout in my bathroom is not acceptable although it's been re-done twice it is of poor quality and not fit for the purpose, BAL products are supposed to be guaranteed for years. We keep the grout clean, scrub it with the spray recommended by BAL but it looks ugly next to large glossy tiles. The bathroom cost just short of £10,000 and it's heartbreaking. Don't get me wrong about the workmen they are very efficient and tidy, but the materials -rubbish. But, Salesman Mis-lead us saying that the white tiles/grout will not discolour as it's treated and "we use all the best materials ..." that was after I expressed my concerns he was a bit quick with his response, this bathroom was fitted last June, and we have not resolved this problem yet. I don't like being a nuisance but given the price and quality I'm not very satisfied. If you're thinking of going ahead with a new bathroom please choose dark tiles/grout or you'll end up in my situation."
