The Island Kitchen Trend: Installing Sinks Anywhere with Sanivite
Modern kitchen islands create an open, social space for cooking, dining, and entertaining. However, placing a sink in the centre of the room can create complex drainage challenges. Sanivite from SFA India offers a compact under-sink pumping solution that allows sinks, dishwashers, and additional basins to drain without relying on a nearby gravity drain. With flexible installation options and quiet operation, it helps bring island-kitchen designs to life.
Walk through a new apartment showcase today and the kitchen has usually stepped out from against the wall. It sits in the middle of the room, wrapped in a stone-topped island, with stools on one side and the cook on the other. The look is open, social, and a long way from the closed kitchen many homes grew up with. What the brochure rarely mentions is the sink. On a wall, a sink is easy. In the middle of a floor, it is a plumbing problem waiting for someone to notice.
That is the gap the Sanivite grey water lifting pump from SFA India was built to close. It is a compact under-sink pump that lets a sink, and the appliances around it, drain from wherever the design wants them, whether or not a drain happens to be nearby.
Why the Island Sink Is Really a Drainage Problem
Gravity drainage asks for two things: a downhill path and a stack within reach. A kitchen island, by definition, has neither. It stands several feet from the nearest wall, and the waste pipe that would serve it has to travel across a finished floor to get anywhere useful.
The conventional answers are not pleasant. Trenching the slab means breaking tiles, cutting concrete, and re-screeding afterwards. Raising the island on a plinth hides the pipe but changes the height of the whole counter. Moving the sink back to the wall defeats the reason for the island in the first place. Each option costs time, adds dust, and quietly trims the design the homeowner paid an architect to draw.
How Sanivite Changes the Plumbing Logic
Sanivite grey water pump replaces the downhill path with a pump. Wastewater from the island collects in the unit and is then pushed out through a slim 32 mm discharge pipe, up to 5 metres vertically or 50 metres horizontally. The route to the stack no longer has to be the shortest or the lowest. It only has to exist.
The unit takes up to four inlets of 40 mm each, so the island's sink, a dishwasher, and a second basin can share one pump instead of each needing its own drain line. Made at SFA's factory in Brégy, France, and carrying the Guarantee of French Origin, it comes from a company that has spent more than six decades, since 1958, solving exactly this kind of problem for homes where conventional plumbing runs out of road.
Planning the Island Around the Pump
The pump is small, but an island is a tight piece of joinery, and it pays to decide where everything goes before the carpenter starts cutting. A few points are worth settling early:
- Give it a bay of its own. Sanivite measures 420 x 180 x 321 mm and weighs 6.4 kg. A dedicated base cabinet under or beside the sink, with no fixed shelf in the way, keeps it accessible.
- Put the service door on the cook's side. The seating side of an island is for knees and stools. Access panels belong where the person doing the work stands.
- Decide the pipe route before the flooring goes down. The 32 mm line can run along the base of the island, then behind skirting, through a floor void, or up into a ceiling cavity on its way to the stack.
- Bring power into the island. The pump needs a 220 to 240 V supply (400 W). Most islands already carry electrical conduit for sockets, so the pump socket can share that planning.
- Keep the fixtures above the pump. The inlets sit low and the switching height is 95 mm, so the pump belongs below the sink and appliance outlets, which is where an island base cabinet naturally puts it.
An open-plan home also raises a question a wall kitchen never faces: noise. With the pump only a few steps from the sofa, its 42 dB(A) sound level matters, and it is quiet enough to sit alongside normal conversation.
Three Island Setups Worth Considering
The prep-sink island. The main sink stays on the wall where the stack is. The island gets a small secondary sink for vegetables and drinks, drained by Sanivite grey water lifting pump through a short discharge run. This is the lightest-touch way to get an island sink into a home that is otherwise finished.
The sink-and-dishwasher island. Both the main sink and the dishwasher sit in the island, facing the living area so the cook is not staring at a wall. A single Sanivite handles both through separate inlets, and the discharge line travels to the stack through the floor void or along the island's plinth.
The long-run villa island. In larger homes the island can sit well away from any plumbing. Because the pump can push wastewater up to 50 metres horizontally, the sink can sit exactly where the architect placed it and the pipe takes whichever service route is least disruptive.
Before You Commit: A Short Reality Check
Honest planning avoids unhappy surprises, so it is worth confirming a few things. Sanivite grey water pump is designed primarily for residential kitchens, which suits the island trend, but it is not the right unit for a busy commercial setup. Incoming water should stay within 40°C, with brief spells up to 60°C of no more than five minutes, so check the discharge temperature of the dishwasher you plan to connect. And as with any installation, the discharge route should be confirmed with your plumber and designer before the island is built, not after.

Put the Sink Where the Design Wants It
The island kitchen is here to stay, and the sink is the part that makes it genuinely useful. With Sanivite, it no longer has to be the part that makes it difficult. Explore the Sanivite grey water pump here or contact SFA India for more information.
Frequently Asked Questions
Sanivite should be positioned below or beside the sink and connected appliances, preferably inside a dedicated base cabinet. The cabinet should provide enough space for the unit and allow easy access for servicing.
The unit needs a clear installation area that accommodates its 420 × 180 × 321 mm dimensions. A dedicated cabinet bay without a fixed shelf is recommended to preserve access for maintenance.
Wastewater pumps are useful for kitchen islands, home extensions, converted spaces, renovated properties, and layouts where the sink or dishwasher is far from the existing drainage stack. They are particularly valuable when changing the floor level or relocating the main drain is impractical.
Yes. Sanivite can be a practical option for finished kitchens because it may reduce the need for extensive floor breaking or structural alterations. The discharge route must still be planned and approved by a qualified plumber.
In many renovation and island-kitchen projects, a wastewater pump can help avoid extensive floor work. Instead of creating a new gravity drain beneath the finished floor, wastewater can be pumped through a smaller discharge line to a suitable connection point.
No. A wastewater pump can provide greater design flexibility by allowing fixtures to be placed away from a wall-mounted drain. The plumbing route still needs to be planned carefully, but the sink location does not have to be dictated solely by gravity drainage.
