Hi everyone. Apologies in advance if this post is a little long winded. Couple of years ago, a friend of a friend offered to tile my bathroom. It was a total disaster from start to finish. The tiling was a mess (worse than any I've seen on here) and to top it off, there were threats of violence when I complained. Anyway...got someone else to do the new shower enclosure and one wall (which I really like) but he became ill and couldn't finish the job. I then sought advice from a forum and some guy offered to finish and make right the floor and 2 walls. I was unwell at the time, so went to stay with family while the work was being done. He said it was best to tile over the bad tiles, which surprised me, but I'm not a tiler, so agreed. He was going to purchase the polished tiles I showed him (said he would get a discount). When I returned home, the tiles were dull matt. not polished like the shower enclosure and opposite wall. I also noticed that the finishing was not very good (see pics) I should have kicked up a fuss, but after the first "tiler" I just wanted a quite life without the hassle. I was pleased to finally have a working, clean bathroom. So after that back story, I'm now (a few years later) looking at my tiles and hating them. I don't know much about tiles, but they are stone, and I don't think they were treated. So they now look dirty, and I can't get the marks off. The grouting is also dirty, and I've tried different cleaners, but nothing works. So finally (lol) my question is: Do I start again? which would mean finding another tiler and digging up 2 layers of tiles from the floor and 2 walls (neighbours will love that lol) or is it possible to paint/stain them? If so, how would I go about that ie: what primer etc... I have health issues, so would still need to find someone to do the work. I'm quite happy to have the bad tiles redone, but a little worried about how long it would take to strip the tiles so as not to disturb my neighbours. Yes, I'm a wuss, and hate confrontation. Just want a quiet life, and a nice bathroom Any advice would be much appreciated Pics are of dirty marks/grouting, and some pics to give an idea of the layout/ tiles in general.
