In dense urban environments like Mumbai, space is always at a premium. With growing families and multi-functional living requirements, homeowners are constantly exploring ways to expand usable areas within their properties. One often-overlooked opportunity? Basement conversions.
However, converting a basement into a livable space especially when adding a bathroom—poses a major challenge: lack of gravity drainage. Digging up floors or modifying the main drain line in high-rise or compact residential buildings is usually expensive, disruptive, and sometimes not even allowed due to structural constraints.
This is the story of how one Mumbai homeowner transformed their unused basement into a fully functional guest suite with a modern toilet thanks to the Saniaccess 3 macerator pump from SFA India.
The Challenge: Adding a Toilet in a Basement with No Drainage Access
The homeowner, residing in a 3BHK flat in central Mumbai, wanted to convert their unfinished basement into a guest room with an attached bathroom. The room was spacious and perfect for this purpose, but it lacked access to a traditional soil pipe.
Key challenges included:
- No slope for gravity-based drainage
- Inaccessible main sewage line (located on the ground floor, several feet above the basement)
- Building regulations that restricted heavy civil work
- A tight installation timeline (less than a week)
Traditional solutions like floor excavation or installing a pit for a sewage pump were ruled out due to:
- Structural risks
- High cost
- Time and labor involved
The goal was to add a toilet, hand wash basin, and a shower without disturbing the floor or the building’s sewage infrastructure.
The Solution: Saniaccess 3 Macerator Pump
After consulting with the plumbing contractor and researching options, the homeowner opted for the Saniaccess 3 from SFA India an above-floor macerator pump designed for toilet installations in spaces without gravity drainage.
Why Saniaccess 3?

Installation Process
1. Design and Planning
- A compact wall-hung toilet was selected to match the minimal aesthetic.

- The Saniaccess 3 was installed behind the toilet wall, concealed in a custom cabinet with an access panel.
2. Plumbing Connections
- The toilet connected directly to the macerator inlet.
- The hand wash basin and shower were linked via side inlets on the unit.
- The discharge pipe just 32 mm in diameter was routed vertically along the wall and then horizontally across the ceiling to the nearest soil stack on the ground floor.
3. Electrical Setup

- An independent switch was installed for manual control and servicing.
4. Testing and Finishing
