An assemblage of modular units are adapted to be positioned along a wall. Each of the modular units has piping at predetermined locations within the enclosure defined by the unit. The ends of the units are open and the piping extends approximately to the end of the unit where it can be coupled to the corresponding piping of another unit. Different units have different fixtures thereon as, for example, one unit has a faucet connected to the hot and cold water pipes, while another unit has gas outlets connected to the respective gas pipes, etc.
