Round Glass Vessel Sink with Diamond-Cut Facets

Both mount above the counter, so the decision is about appearance and handling. A glass vessel sink like this one is non-porous and turns the diamond-cut facets into a refractive feature — it reads as a design centerpiece, which suits powder rooms, boutique hotels, and feature vanities where the basin is meant to draw the eye. Ceramic vessels are more familiar to installers and more forgiving of rough handling, so they often fit back-of-house or very high-traffic areas. For design-led residential and hospitality vanities, glass gives the more distinctive result; for utilitarian volume, ceramic is the safer default. SANIKB manufactures both, so a single project can specify glass at feature points and ceramic elsewhere.

These bowls have no overflow, which is standard for above-counter vessel basins — there's no second hole, so water exits only through the center drain. Install with a free-flow (non-overflow) pop-up or grid drain rather than an overflow-style drain, and seat the bowl on a thin bead of clear silicone so nothing shows through the glass. Because the rim sits well above the counter, pair it with a tall vessel faucet or a wall-mounted spout that reaches over the edge — a standard deck-mount faucet sits too low. Confirm the drain opening and faucet-hole layout on the spec sheet for your selected finish before the counter is cut.

The glass surface is non-porous, so it won't absorb stains or odors — routine cleaning is just a soft cloth with a mild, non-abrasive cleaner. Two things to plan for with any glass basin: it shows hard-water spotting more readily than ceramic, so in hard-water regions, wiping the bowl dry after use keeps the diamond-cut facets clear and bright; and abrasive pads or scouring powders can dull a glass surface over time, so avoid them. Cared for this way, the faceted surface stays sharp and reflective through daily residential and hospitality use.

Every finish is made from tempered (toughened) safety glass, heat-treated for impact and thermal resistance with smooth, finished edges. Tempered glass is impact-resistant but not unbreakable — its defining safety property is how it fails: if a hard point impact ever breaks it, it shatters into small, blunt granules rather than long sharp shards, which is exactly why toughened glass is specified for basins and other fixtures. In everyday use, avoid thermal shock — don't pour boiling water into a cold bowl — and clean with non-abrasive products.

Glass is packed for ocean freight, not parcel shipping. Each bowl is individually cushioned and cartoned, then palletized for container loading so it withstands the handling and stacking of LCL and FCL sea transport. Because orders often combine several finishes, cartons are labeled by SKU so receiving and warehouse distribution stay straightforward. SANIKB also welcomes pre-shipment inspection, so your team can verify both product quality and packing before the container is sealed at the factory.

These sinks are sold factory-direct to trade, with a minimum order of 100 pieces. Each finish is a separate SKU, and OEM/ODM and private-label programs cover custom color matching, custom sizing, your own logo, and export packaging built for ocean freight. Standard lead time is 30–45 days, confirmed against order size, finish mix, and any customization. Send your quantities, target finishes, and destination port, and SANIKB returns a costed FOB or CIF quote within 12 business hours — or browse the full glass vessel sinks collection to compare options first.
