Right Size, Undermount Profile
At 686×483mm with a 254mm depth, the BK-6848 sits in the sweet spot for mid-size kitchens. The undermount installation means the sink mounts beneath the countertop with the rim concealed below the bench surface — no rim visible, so you can wipe water and crumbs directly into the sink. An 800mm cabinet base is required.
16 Gauge SUS 304 — The Commercial Kitchen Thickness
At 16 gauge (1.5mm), the BK-6848 uses the same thickness specification as commercial kitchen equipment. The heavier gauge means the basin doesn’t flex when you set a full pot down, doesn’t drum loudly when water hits the base, and holds its brushed appearance through years of daily use without the wear patterns you see in lighter gauges.
Anti-Condensation Coating — Protecting the Cabinet
The external surface of the BK-6848 is coated with a grey anti-condensation layer — the same technology used in premium kitchen sinks to prevent moisture from forming on the outer surface of the basin. In high-humidity kitchens or when plumbed with hot water, an uncoated stainless steel sink can sweat onto the cabinet surface below. The BK-6848’s coating eliminates this at the source.
Thickened Silencing Cushion — A Quieter Kitchen
The base and side walls of the BK-6848 are lined with a thickened rubber/synthetic silencing layer that dampens the sound of running water and reduces resonance from pots and dishes. For open-plan kitchens where the sink is in earshot of the living area, this makes a meaningful difference to daily comfort.
Offset Drain — Cabinet Space Preserved
The drain is positioned at the rear of the bowl, leaving the front portion of the under-sink cabinet free for storage or a waste disposal unit. The rear position also means the front half of the basin is completely flat — more usable space for large items that don’t fit in a centre-drain sink.
Undermount Installation — Seamless Benchtops
The BK-6848 is designed for undermount installation: the sink mounts beneath the countertop, with the rim concealed below the bench surface. No rim means you can wipe water and crumbs directly from the counter into the sink without anything catching. The result is a cleaner counter and a more hygienic kitchen.

Q: Will the BK-6848 fit in a 750mm cabinet base?
A: The BK-6848 requires a minimum cabinet base of 800mm. A 750mm cabinet base is not recommended — there won’t be enough mounting surface for a secure undermount installation.
Q: Is 16 gauge noticeably better than 18 gauge?
A: Yes. The difference is felt in two ways: physical rigidity (16 gauge won’t flex noticeably under heavy loads) and acoustic character (16 gauge produces a duller, less hollow sound when water hits the base). For sinks used daily, 16 gauge provides a meaningfully better experience.
Q: What does the anti-condensation coating do?
A: The coating is applied to the outer surface of the basin — the side facing the cabinet. It creates a thermal barrier that prevents warm moist air inside the sink from condensing on the cooler metal surface and dripping into the cabinet below. This is especially useful when the kitchen is air-conditioned or when the sink is plumbed with hot water regularly.
Q: How effective is the silencing cushion?
A: The thickened layer on the base and sides of the BK-6848 significantly reduces the drumming sound associated with stainless steel sinks. It’s particularly effective for open-plan kitchens where sink noise travels into living areas, and for households where the kitchen is used early morning or late evening when sound carries more.
Q: Does the offset drain affect drainage?
A: No. The offset positions the drain to one side rather than the centre, which actually maximises the usable flat area of the basin. Drainage is not compromised — the angled base still channels all water toward the rear drain efficiently.
Q: Can a garbage disposal be installed with this sink?
A: Yes. The offset drain position works well with a garbage disposal as it positions the unit to one side of the cabinet, leaving more usable storage on the other side.
The Kitchen Sink That Doesn’t Announce Itself.
Quiet in use, solid under hand, and built to protect the cabinet below — the BK-6848 is the mid-size undermount that does its job well without demanding attention.
