Case Study: How 21 Sanipack Pumps Created Hotel Bathrooms Without Core Cutting

Turning an existing building into a hotel sounds simple on paper. The rooms are already there, so it is mostly a matter of fitting them out. The difficulty arrives at the bathrooms. Every hotel room needs its own WC, washbasin, and shower, and every one of those fixtures needs a way to drain. In this project, the building ruled out the usual way of providing it. This case study shows how SFA India solved the problem with 21 Sanipack macerator pumps.

Project at a Glance

The Challenge

The client wanted to convert the 1st and 2nd floors of the building into a hotel, which meant creating complete bathrooms for multiple rooms. Each bathroom needed a WC, a washbasin, and a shower.

Conventional drainage was the obvious route, but two limits stood in the way:

• No core cutting. The building did not permit core cutting, so new drainage lines could not be run down through the floor slabs in the usual way.
• No floor raising. The alternative of raising the floor level to hide pipework and create a gravity fall was not feasible either. It would have added load to the existing structure and affected the overall design.

With both options closed, creating fully functional bathrooms through traditional plumbing would have required major structural changes. The project needed a different approach to drainage altogether.

The Solution

SFA India recommended the Sanipack macerator pump and supplied 21 units, one for each washroom. Each Sanipack was connected to the WC, washbasin, and shower cabin of its room.

The compact unit was installed neatly behind the bathroom partition, out of sight. Wastewater from all three fixtures flows into the Sanipack, where it is macerated and then pumped through small-diameter pipework to the available drainage line.

This approach meant the drainage no longer depended on cutting through floors or building up levels. The client could create complete, modern hotel bathrooms on both floors without core cutting, floor raising, or major modifications to the existing structure.

The Result

• 21 hotel bathrooms created across the 1st and 2nd floors
• No core cutting required
• No floor raising, and no added load on the existing structure
• The building's original design left largely undisturbed

About the Sanipack Macerator Pump

The Sanipack is an extra-slim macerator pump designed to be hidden from view, where wall-hung or back-to-wall sanitaryware is wanted. It takes waste from a WC, washbasin, and shower, and its macerating system breaks the waste down so it can be pumped through narrow pipework to the drain. It is built for installing a complete shower room or fitted bathroom without digging a pit or cutting the floor.

Key Benefits of the Sanipack

• No core cutting or pit digging: a bathroom can be added without breaking through the floor.
• Complete bathroom from one unit: it connects the WC, washbasin, and shower together.
• Extra-slim and concealable: compact enough to sit behind a partition or wall-hung WC frame.
• Small-diameter discharge: wastewater leaves through slim pipework (32 mm recommended), which is far easier to route than a full-size drain.
• Pumps up and away: up to 5 metres vertically, so the bathroom does not need a downhill run to the drain.
• Easy maintenance: designed for servicing without removing the unit.

Where the Sanipack Is Used

• Hotel and guesthouse conversions: adding en-suite bathrooms to existing rooms, as in this project.
• Upper floors and older buildings: where slab cutting is restricted or structure cannot take extra load.
• Commercial and office spaces: adding washrooms where no drain is close by.
• Homes: basement, loft, and extension bathrooms, or an additional bathroom in a small space.

Planning a Bathroom Where Drainage Is the Obstacle?

If your building does not allow core cutting or floor raising, talk to SFA India before the design is fixed. The right wastewater lifting pump can turn a restricted site into a workable one.
