Our new house has two fully tiled bathroom (main and ensuite) and I think the tiles are dreadful. The family bathroom is poo brown with a brown flock shiny pattern and beige floor and the ensuite is white with small black circles and black with big black shiny circles. My instinct is to rip out all the tiles and only have a small amount of replacement tiles where needed for waterproofing. However, my head says that's too expensive. Should we retile the whole walls? Poster them and only retile small areas? Paint the existing tiles? They rooms were done at most 10 years ago.
