Hi, I need to design a new bathroom that needs to have tiles up to 120 cm from the floor for most of the walls and in 2colors ( I want a dark stripe behind the basin and the shower) and up to 190cm behind the shower. Can anyone tell me how to "paint" walls in a free way? I have seen some demos around of bathrooms with part of a wall covered with mosaic while all the remaining wall area was white. Thanks
