[Case study - 54] Basement renovation without breaking structure – Sanitop pump from Sanitoilet solution for a spa in District 7
A spa owner in District 7 successfully converted a basement into a fully equipped staff area without drilling or altering the leased property's structure – thanks to the Sanitop pump by SFA Pumps Vietnam.
Key highlights
- Situation: A spa operating on a leased premises in District 7 wanted to convert the basement into a functional staff amenity area.
- Problem: As a leased space, drilling, breaking floors, or altering the building's structure was not permitted.
- Solution: The Sanitop macerator pump by SFA Pumps Vietnam was installed to enable wastewater drainage without any structural intervention.
- Result: The basement was fully renovated with essential sanitary facilities, with zero impact on the leased property's structure.
When space optimisation meets the constraints of a leased property, the margin for conventional construction is slim. This case study looks at how a spa in District 7 overcame that challenge with a practical, non-invasive pumping solution from SFA Pumps Vietnam.
The challenge
The owner of a spa in District 7, Ho Chi Minh City, was looking to make better use of the available space. To free up the upper floors for customer-facing services, the decision was made to convert the basement into a dedicated staff area – complete with sanitary facilities and basic amenities.
However, a fundamental constraint stood in the way: the property was leased. The lease agreement did not permit any drilling, floor breaking, or structural modifications to the building. Under normal circumstances, installing a bathroom in a basement would require excavating for drainage pits and rerouting pipework – neither of which was an option here.
The requirement was clear: deliver a fully functional staff amenity space in the basement, without touching the building's structure.
The solution
SFA Pumps Vietnam recommended the Sanitop macerator pump – a compact unit specifically designed for situations where conventional gravity-fed drainage is not feasible.
Sanitop works by macerating waste and pumping wastewater upward against gravity or horizontally through a discharge pipe, routing it directly into the building's existing drainage network. No floor breaking, no drainage pit, no structural alteration requir
The unit features two inlets, allowing connection to both a toilet and a washbasin – sufficient to complete a self-contained bathroom in the basement. Its compact footprint and flexible installation make it a project-ready solution for spaces with construction limitations.

The results
Following installation of the Sanitop pump, the spa's basement was successfully converted into a fully equipped staff area, featuring a self-contained bathroom with toilet and washbasin.
The entire installation was completed without any structural impact on the leased premises, in full compliance with the lease conditions. The system has since operated reliably, handling wastewater collection and transfer efficiently without disrupting daily business operations on the floors above.
The spa owner was able to optimise customer-facing space on the main floor while providing proper amenities for staff – all within the constraints of a leased property.
Conclusion
This project in District 7 demonstrates that converting a basement into a functional living space within a leased property is entirely achievable – with the right solution in place. The Sanitop pump by SFA Pumps Vietnam met the project's strict requirements: effective wastewater collection and transfer with no structural intervention whatsoever.
For business owners, designers, and contractors facing similar constraints, Sanitop offers a flexible, project-ready solution that removes the need for disruptive construction while still delivering full sanitary functionality.

Any questions ?
Sanitop is a macerator pump by SFA Pumps that grinds waste and pumps wastewater upward against gravity or along a horizontal discharge pipe. It connects directly to the building's existing drainage without requiring floor excavation or drainage pits.
Sanitop features two inlets, allowing simultaneous connection to a toilet and a washbasin – enough to set up a complete, self-contained bathroom unit without a conventional drainage system.
Beyond spas, Sanitop is well suited to any project requiring additional bathroom facilities in a basement or low-level space – including offices, restaurants, shophouses, renovated apartments, and other commercial leased premises where structural modifications are not an option.
Yes – this is one of Sanitop's key advantages. The unit installs without drilling floors, breaking walls, or altering any structural elements, making it ideal for leased spaces where construction modifications are restricted.
Installation is significantly faster than traditional drainage methods since no floor breaking or pit excavation is required. Actual time will depend on the specific site conditions and layout of each project.
