To have a toilet in a basement, a macerating toilet can be used. This kind of toilet connects to a macerator unit behind it, which pumps waste through a 3/4-inch (1.9 cm) discharge pipe after grinding it up with stainless steel blades. The macerating unit should be installed in the basement first since the unit goes behind the toilet and connects to piping that sends waste up to and through a house's main plumbing system. Try following these steps to install a basement toilet.

      • The macerator unit can also connect a sink (lavatory) or shower for basement plumbing as well. PVC pipe and fittings are needed for the connections.

      • Other waste storage systems such as creating a sewage basin or using a floor-mounted polyethylene tank can possibly be used in basements. These options use a standard toilet, which works differently from a macerating toilet.
