Semi Recessed Basin Sink Square Drop In Bathroom Sinks with Overflow Stainless Steel Vessel Sinks for Bathroom Modern Above Counter Basin Vanity Sink

Semi-Recessed Design — The Practical Middle Ground

A vessel sink sits fully on the counter. An undermount sink sits fully below. The BB-5810 semi-recessed basin splits the difference — it drops through a countertop cutout with the front half sitting above the counter and the rear sitting flush or slightly below. This gives you the clean aesthetic of a vessel sink while using less counter space.

Who Benefits from Semi-Recessed Installation:

The BB-5810’s design is specifically useful in:

• Compact powder rooms where a full vessel sink would dominate the vanity

• Guest bathrooms where counter space is limited but the basin needs to look considered

• Renovation projects where wall-hung vanities have been removed and a drop-in solution on existing cabinetry is needed

• Hospitality installations where the semi-recessed look is part of the design language

400×400mm — Perfect Square Proportion

At 400mm wide and 400mm deep, the BB-5810 provides a balanced square basin area without the visual weight of a full vessel sink. The square form fits neatly on standard vanity cabinets and is well-proportioned for the single-user bathroom it is typically designed for.

Stainless Steel with Overflow

The BB-5810 includes a overflow channel — an important feature for bathroom basins that prevents accidental overfilling and water damage. The overflow is integrated into the stainless steel body and drains via the centre drain outlet.

Product Dimension

Ideal For:

• Compact bathrooms and powder rooms

• Guest ensuites with limited counter space

• Renovation projects where existing cabinetry is being retained

• Hospitality installations (hotel bathrooms, boutique accommodation)

FAQ

Q: What is the difference between a semi-recessed and a standard vessel sink?
A: A vessel sink sits entirely on top of the counter, requiring more vertical clearance and visually dominating the vanity. A semi-recessed sink drops partially through the counter — the front rim sits above the counter surface while the rear is supported by the cabinetry below. This reduces the visual height of the sink and the counter footprint it occupies.

Q: Can the BB-5810 be installed on a marble or stone countertop?
A: Yes. The BB-5810 requires a cutout of approximately 380×380mm in the countertop. Stone, granite, marble, quartz, and solid surface materials are all suitable for this installation. The cut edge should be sealed to prevent moisture ingress.

Q: Does the BB-5810 come with tap mounting provisions?
A: The BB-5810 is a drop-in basin designed to work with countertop or vessel-type taps. The tap is mounted on the countertop surface behind the basin, with the supply lines running to the wall or through the vanity. Confirm tap specifications with your plumber before finalising the installation.

Q: What is the advantage of including an overflow?
A: The integrated overflow prevents the basin from overfilling if the drain is accidentally left blocked — an important safeguard in bathroom installations, particularly in households with children. The overflow channel is concealed within the stainless body and drains through the main outlet.

Q: How is the BB-5810 different from the BB-5811?
A: The BB-5810 is square at 400×400mm. The BB-5811 is rectangular at 510×360mm — a more compact form better suited to very small bathrooms. Both are semi-recessed drop-in basins with similar construction, but the BB-5810 offers a different shape for square countertop configurations.

The Basin That Does More With Less.

In bathrooms where every centimetre of counter matters, the BB-5810’s semi-recessed design gives you the look of a vessel sink without sacrificing half your vanity. Modern, considered, and practical.
