The SANICOMPACT toilet from Saniflo installs quickly and easily anywhere, with no venting required. In addition to handling toilet waste, the toilet can also pump water away from a nearby sink. This fixture saves space through a sleek design that measures 14.5” wide and 21.5” deep, and combines a macerating pump and a tankless toilet bowl into a single fixture. Operating with only 1-1.28 gpf, the self-contained toilet uses about 38% less water than a standard 1.6 gpf toilet, Saniflo notes. Saniflo.
