The Smallest Semi-Recessed Option — When Space Is the Brief
The BB-5811 is BECASUS's most compact semi-recessed basin — a rectangular silhouette at 510×360mm. Where the BB-5810 is the larger rectangular option at 700×430mm, the BB-5811 drops into vanity cabinets and countertop configurations where the larger model simply won't work. Same semi-recessed concept, scaled for tighter spaces.
Compact Without Compromising Function
At 510mm wide, the BB-5811 is designed for the smallest meaningful bathroom installation — the ensuite off a master bedroom, a compact powder room, or any bathroom where standard 600mm vanities are already at maximum capacity. The 360mm depth ensures the basin remains proportionally balanced without extending too far into the vanity.
Semi-Recessed = More Counter Space
The key advantage of the semi-recessed format is that part of the basin sits below the counter surface. This means you retain more usable counter space behind the basin than you would with a full vessel sink of equivalent basin dimensions. For compact bathrooms where a soap dispenser and toothbrush holder need a home, every extra centimetre of counter matters.
Stainless Steel with Overflow
The BB-5811 includes an integrated overflow channel — an important safety feature that prevents accidental overfilling. The overflow is concealed within the stainless body and drains via the centre outlet. A popup drain assembly is included.

## FAQ
Q: What is the minimum vanity cabinet depth for the BB-5811?
A: The BB-5811 requires a minimum vanity cabinet depth of 360mm. A standard 500–520mm vanity cabinet depth provides adequate clearance. Ensure the cabinet has a cutout of approximately 490×340mm to accommodate the semi-recessed installation.
Q: Does the BB-5811 require a specific type of tap?
A: The BB-5811 works with standard countertop-mounted or vessel-type basin taps. The tap is mounted on the counter surface behind the basin. Wall-mount taps are also compatible but require a different plumbing configuration. Confirm tap specifications before finalising the installation.
Q: Can this be installed as a fully above-counter vessel sink?
A: The BB-5811 is designed for semi-recessed installation — it drops partially through the countertop. Installing it fully on top of the counter (as a standard vessel sink) would raise the effective rim height significantly and may not look proportional. If a fully above-counter vessel installation is required, consider a dedicated vessel sink model.
Q: How does this compare to the BB-5810?
A: The BB-5811 is smaller and rectangular (510×360mm) vs the BB-5810 which is also rectangular (700×430mm). Both are semi-recessed drop-in basins. The BB-5810 is for standard compact bathrooms; the BB-5811 is for very tight installations where even 600mm vanities are at their limit.
Q: What is the overflow outlet direction?
A: The BB-5811's overflow channel is integrated into the stainless body and drains through the main centre drain outlet. There is no separate visible overflow opening — the design maintains a clean, uninterrupted stainless appearance.

When the Bathroom Doesn't Give You Room to Spare.
For the smallest bathrooms and tightest ensuites, the BB-5811 proves that considered design doesn't require generous dimensions. Semi-recessed, stainless, and sized for spaces where every millimetre is accounted for.
