Color & Contrast

A Dark Nero Marquina Bowl at 16.5 Inches Across

Nero Marquina is a black and white marble. SP516 works it into a round bowl 420 mm across and 140 mm high.

01 / TONE

Charcoal body, white veining

The stone reads as charcoal across a room, with white veining visible up close. The color is solid stone, not a coating.

02 / SIZE

Compact 420 mm circle

At 16.5 inches the bowl fits vanities where a larger basin would crowd the tap. Height stays at 5.5 inches.

Dark bowls sell against pale counters, so tone matching matters at display stage. Compare tones across the above-counter stone basins.

Fit & Clearance

Compact Round Basin Clearances at 420 mm

Rim height is the number that decides the tap. This body puts it 140 mm above the counter.

Outside diameter 16.5 in (420 mm)
Overall height 5.5 in (140 mm)
Shape Round
Mounting Above-counter (vessel)

A 420 mm circle leaves usable counter on both sides of a single vanity. Keep clear stone behind the bowl for the faucet base, sized to the tap you pair.

A wall-mounted tap removes the clearance question. Send the spout height and we will check it against the 140 mm rim.

The drawing governs the drain opening. Ask for it before the counter is cut.

Construction & Finish

Polished Nero Marquina, Black Stone With White Veining

Cut from natural block and polished.

Nero Marquina

Vein density varies by block

Some pieces carry heavier white veining than others. Tell us whether a client wants the quieter or the busier end of that range.

Dark polished stone shows limescale and soap film sooner than pale stone. Include care guidance in the carton if the basin reaches end users.

Dark stone is hard to judge from a screen. A physical sample settles it.

Compliance

Paperwork the Destination Market Will Ask For

DOC
Drawing and tone reference

Useful when a dark basin has to be approved against a pale counter sample.

The SP516 record covers Nero Marquina marble, round vessel form, 420 x 140 mm, mount and finish. It carries no certification, so none is claimed here.

Some markets ask for a stone origin statement alongside the commercial invoice. Give us the destination country so paperwork is agreed before booking.

Procurement

How the SP516 Dark Bowl Ships in Volume

Wholesale supply to importers, distributors and fit-out contractors.

Published MOQ 50 pcs
Standard Lead Time 30-45 days (typical)

Vein density preference, alternative dark stones and own-brand cartons run through the SANIKB OEM and ODM program.

Include these details with the RFQ

  • Quantity and phased delivery dates
  • Import documents for the destination country
  • Preferred white vein density for the lot
  • Drain and overflow specification
  • Carton marking and own-brand artwork
  • Sample piece before bulk production

Lead time comes from the quotation once the lot is scheduled against production.

FAQs

What gives this black stone vessel sink its color?

It is cut from Nero Marquina marble, a deep black stone crossed by fine white veins, with a distressed charcoal surface on the bowl exterior.

Is this a compact round basin suitable for smaller vanities?

Yes, at Ø16.5" x 5.5" H (Ø420 x 140 mm) it is a smaller round vessel that works well on powder-room and guest-bath vanities.

Can the distressed finish be ordered in volume for a hotel rollout?

Yes, we produce the distressed charcoal finish in repeatable batches for property-wide programs, with samples available before bulk production.
