Why it matters

The Sanishower handles gray water only, from sinks and showers, not toilets. Its 0.2 HP motor pumps up to 20 GPM, 12 ft up or 100 ft along, per Saniflo.

Low inlets let it sit under a shower base or in a cabinet, it runs at about 44 dBa, and a rotating discharge elbow and non-return valve simplify installation.
