Many of my clients have asked about installing bathroom fixtures in a basement without below floor sanitary drains.
The answer is always yes because of the products that are available to pump waste “up” to a drain line.
Saniflo and their Sanishower line has a unique pumping system available that can connect shower and sink grey water to a higher drain line as well as a solid waste pumping system for toilets. These systems do not require the normal holding tank beneath the fixture and can convert any corner in your basement into a useable bathroom.
