SANIFLO products allow installation of a bathroom appliance or a complete bathroom where you want it, not where plumbing dictates. A patented, 'above-the-floor' plumbing system minimizes construction, and there are no pipes to hide. Saniflo toilets require just 6 liters of water. A maintenance-free macerator unit houses a powerful rotating blade that shreds and grinds solid waste, allowing it to mix with flushing water and to move through 3/4" pipe to the sewage system, septic tank or holding tank.
