Flexible drainage outlet
The adjustable drain hose that connects a freestanding HERA bathtub to your existing floor trap, so no new plumbing is needed.
What it means
A flexible drainage outlet is the short, adjustable hose fitted to the underside of a freestanding bathtub. When you pull the plug, water leaves the tub through this hose and flows into the floor trap your bathroom already has. It is the piece that lets a bathtub use your existing drain instead of needing new pipes run into the floor or walls.
Because the hose is flexible, the bathtub does not have to sit directly on top of the drain. The outlet reaches across to wherever the floor trap is, and the connection is made with a watertight seal. The seal is a coupling of the kind used for portable washing machines and similar appliances for decades, so it is a well-proven fitting rather than a workaround.
The important contrast is with a built-in tub, where the water inlet and the drainage are permanently piped into the floor and walls. A flexible drainage outlet is the opposite: nothing is buried, nothing is cemented, and the connection can be undone at any time without leaving a mark. The tub's overflow drains through the same route, so excess water follows the same path out.
In a Singapore home
The flexible drainage outlet is the reason a HERA bathtub needs no renovation in an HDB flat or condo. The bathtub connects to your existing floor trap, so there is no hacking, no tiling, no new waterproofing, and no plumbing modifications. The simple test we give customers: if you can pour water from a kettle into your existing floor trap and watch it drain, your bathroom can take a HERA bathtub.
The outlet comes included with every HERA bathtub. On installation day the team positions the tub, levels the adjustable feet, connects the flexible drainage to the floor trap with a watertight seal, then partly fills and drains the tub to confirm there are no leaks at the joint. The installation itself usually takes around 30 to 45 minutes, and professional installation costs between $126 and $432 depending on your bathroom layout, drainage position, and floor level. Full details are on our delivery and installation page, and the step by step process is walked through in our guide to installing a bathtub without renovation in an HDB.
The same connection also protects you later. Drainage components are covered under the 1-year HERA warranty, and because the outlet simply unclips from the floor trap, resolving any issue, or moving the bathtub to your next home, never requires reworking your bathroom.
Quick questions
Is the flexible drainage outlet included with the bathtub?
Yes. The flexible drainage outlet ships with every HERA bathtub. On installation day the team connects it to your existing floor trap with a watertight seal and runs a leak test before leaving.
Will the flexible drainage outlet leak?
No. It uses a sealed coupling of the kind used for portable washing machines and similar appliances for decades. The leak test on installation day confirms the seal is good before the team leaves, and any minor adjustments are made on the spot.
Do I need a plumber to connect a flexible drainage outlet?
No. The HERA installation team handles the drainage connection as part of a single service, so there is no need to engage a separate plumber, contractor, or renovation crew.
Can I disconnect the flexible drainage outlet if I move house?
Yes. The connection can be undone at any time without leaving a mark. Disconnect the outlet from the floor trap, lift the bathtub out, and the bathroom looks the same as before.
