If your chosen tiles go over the recommended weight or you have walls that are not straight, which is very common with houses from several decades ago, then fear not - tile backing board may save the day. You'll see it on the table above with greater weight allowances.
Floor tiles are ideal for underfloor heating, due to their superior thermal conductivity – the speed and efficiency with which the generated heat is transferred to the floor surface. With tiled flooring, you get a warm room, quicker, and it also retains heat well so is more efficient to run. That means no more chilly bathrooms, conservatories, or kitchens.
It may be true that the best things come in small packages, but unfortunately, it’s not that cut and dry when it comes to finding the best size of floor and wall tiles for a small room. Large tiles do make a room feel more spacious but only in a good-sized room. In a small bathroom, they don’t work quite so well and will tend to swamp the room if they’re too large, especially if there are lots of cuts to the tiles.
