My ensuite is finally finished. I got the tiles that looked like a crack den/basement in the film Saw, removed. I went with advice on here not to fully tile and to go with a brick formation for the background tile. There’s been a bit of a delay due to the feature tiles getting stuck in customs on their way here from Portugal but all done now. Thank you to everyone who commented on my op and shared their experiences that gave me the confidence to do this. So to conclude, I think I was not BU to remove the tiles I didn’t like, I’m so glad I did and I love my tiles!
