Such a simple process as the installation of a bath requires certain knowledge, without which the work itself can be difficult or not at all to the result that was expected. First, you need to choose a location. If you proceed from the standard size of the premises, then the best place will be one of the sides from the front door. True, this option implies the impossibility of installing additional accessories due to lack of space. So, if you plan to install a washing machine in this room, use the designer cunning — install the bath not on the sides of the door, but directly opposite. If there are very few places, purchase a compact-sized upper shell.
