Saniaccess 3: the service-friendly choice
Saniaccess 3 is designed for a complete residential bathroom. Its main advantage is its dual access-panel design, which makes common service areas easier to reach without removing the entire unit.
Saniplus 2: the residential full-bath choice
Saniplus 2 is a conventional full-bath macerating system for a toilet, sink, shower and bathtub. It uses a 0.5 HP motor and is rated for up to 15 feet vertically or 150 feet horizontally, subject to the complete installation layout.
Sanibest Pro: the grinder option
Sanibest Pro uses a 1 HP grinder and provides a higher advertised vertical capability of up to 25 feet. It can be a better fit for rentals, public-facing bathrooms or other situations where use is heavier or less controlled.
Six checks before ordering
- List every fixture and its drain elevation.
- Measure the complete vertical rise and horizontal run.
- Count elbows and confirm discharge pipe size.
- Consider whether use will be private and controlled or heavier and less controlled.
- Preserve access for inspection and service.
- Confirm venting, electrical and local permit requirements.
Bottom line
Choose Saniaccess 3 for service-friendly residential use, Saniplus 2 for a conventional residential full bath, and Sanibest Pro when the installation needs a grinder or higher vertical lift. Confirm the final layout against the current manual and local requirements before purchasing.
