When my house was built, we had used Mosaic tiles. In order to save money, we didn’t use the best tiles at that time. Now in the ground floor of my house, these tiles were worn out and we had replaced them with vitrified tiles about five years ago. But we didn’t do anything about the top floor of the house due to may reasons (which includes financial of course). But now we are thinking about putting some new basement floor tiles on the top floor. This is only a thought at the moment.
