[Case study - 49] The ideal solution for adding wash basins to a spa without floor drilling

When converting a residential property into a service-based business like a spa, the drainage system often becomes the biggest challenge. This is especially true for completed buildings, where adding new wash basins without modifying the structure can be extremely difficult. This was exactly the situation faced by an investor when setting up a spa in a three-story building.

Key highlights

• Situation: A spa was planned on the ground floor and first floor, requiring two wash basin areas for customers
• Problem: No drilling or structural modification allowed; existing plumbing system could not be altered
• Solution: Use Sanishower for the small area and Sanivite for the larger area, connecting to the drainage system on the second floor
• Result: A flexible drainage system installed without construction work, ensuring stable operation

Problem

Structural and technical limitations

Since the building was already completed, drilling into the floor or modifying the structure was not permitted. This made it nearly impossible to install a traditional drainage system for the new wash basins.

No existing drainage at required locations

The wash basin areas on the ground floor and first floor were not located near the main drainage stack. The only option was to connect to the existing drainage system on the second floor, which posed challenges in terms of distance and elevation.

Solution

Utilizing existing systems with a pumping solution

Instead of drilling to reroute pipes, SFA Pumps proposed a wastewater lifting solution that allows water to be collected and discharged to an upper-level drainage system efficiently.

Device allocation based on usage needs

• Small area: Sanishower — compact and ideal for a single wash basin, easy to install in limited space
• Larger area (2 wash basins): Sanivite — higher capacity, suitable for collecting wastewater from multiple fixtures

Quick installation without structural impact

Both units can be directly connected to wash basins and existing pipework, requiring no invasive construction work.

Result

The entire drainage system for the spa was completed without any floor drilling or structural modifications. The wash basins operate efficiently, with wastewater being reliably collected and discharged, meeting the continuous usage demands of the business.

This solution also significantly reduced installation time and renovation costs compared to traditional methods—making it ideal for fast-moving business models such as spas.

Conclusion

For completed buildings or projects with technical constraints, adding a drainage system no longer has to be a dead end. With solutions from SFA Pumps, property owners can flexibly upgrade their space—from residential to commercial use—without complex construction work. This approach is especially effective for businesses like spas, salons, or renovated apartments.
