The SANISHOWER from Saniflo is a fully automatic gray water pump system designed to discharge wastewater from a shower, bathtub, bar or bathroom sink. The compact unit measures 13 inches wide and 6-1/2 inches deep, making it ideal for tight areas where installation space is severely limited: underneath a raised shower stall or lavatory cabinet (see photo), or even concealed behind a wall. Wastewater enters the compact SANISHOWER container via two 1-1/2” inlets, located on either side of the unit, and triggers a micro-switch in the chamber, which activates the pump motor and immediately discharges the wastewater.
