The SANICOMPACT toilet from Saniflo installs quickly and easily anywhere in the home, 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 gallons of water per flush, the self-contained toilet uses approximately 38% less water than a standard 1.6 gpf toilet, the company says. Saniflo.
