The Nantucket Sinks 15.75" Round Italian Fireclay Vessel Bathroom Sink comes in 3 versions: Matte Concrete, Matte Black or Matte White color. Pick your options above to open the exact model, with its own price and details. The details below are for the Matte Concrete version.
The Nantucket Sinks RC4011C is a 15.75" round Italian fireclay vessel sink in a matte concrete glaze with a semi-sheen finish. Calm and elegant, it is a compact focal point for a powder room or modern bath, a perfectly round bowl in an industrial grey that pairs with wood and stone.
Because a vessel sits on top of the counter, plan the faucet with it: a tall vessel faucet on the deck or a wall-mount faucet clears the rim, and Nantucket's matching umbrella pop-up drains, sold separately, come in several finishes. The Regatta Collection, inspired by famous ports, lakes and seaside towns, runs from matte concrete, white and black glazes to metal-leaf and hand-painted pieces, so a powder room and a primary bath can share one collection in different looks.
Every Regatta sink is genuine fireclay, designed and hand finished in Italy and fired at high temperatures, which Nantucket says makes it stronger than typical bathroom sinks. Dimensions are nominal and can vary by about 1/4" from piece to piece, and the bowl takes a standard 1.75" vanity drain (not included).
Perfectly round with a center set drain, the vessel is 15.75" across and 5" tall, with a 15" diameter basin 4" deep. Named for a mountain lake in Italy, it is finished in a serene, even semi-matte glaze that catches and diffuses light in a soft glow instead of reflecting it.
Planning the Vanity
Planning a vanity around it is straightforward. It has no faucet holes, so the faucet goes on the countertop or the wall, and the drain opening takes a vanity drain without overflow made for the 1.75" opening, sold separately, which Nantucket offers as matching umbrella pop-up drains in several finishes. At 20 lbs, the sink is set on the counter or in its cutout with plumbing silicone, and professional installation is recommended.
A vessel sits on top of the vanity, so the countertop needs only the drain hole, and Nantucket's vessel guide asks you to dry fit the sink first and leave at least 5" at the rear of the vanity for a faucet.
Caring for Hand-Finished Fireclay
Each Regatta sink is hand finished in Italy, so look after it gently: Nantucket asks for pH neutral soap and a soft cloth only, no abrasive cleansers or pads, and no improper or caustic cleansers, which can damage the glaze. Fired fireclay will not rust.
For a bathroom or powder room that wants an Italian fireclay bathroom sink with real craftsmanship, the Nantucket Sinks RC4011C turns the vanity into a focal point while staying practical for daily hand washing.
Features
Matte Concrete Glaze
The concrete glaze has a semi-sheen finish that softly diffuses light, giving the round bowl a calm, stone-like surface.
Grey for Organic Spaces
Concrete grey works with warm wood vanities, natural stone and black or brushed fixtures for a modern, organic bath.
Perfectly Round 15.75" Bowl
The round vessel with a center set drain is 15.75" across with a 15" basin, a compact size for powder rooms and small vanities.
Hand Finished in Italy
Each Regatta sink is genuine fireclay, designed and finished by hand in Italy, so small variations make every piece unique.
High-Fired Fireclay
Fired at high temperatures, the sink is, in Nantucket's words, stronger than typical bathroom sinks, and the glaze will not rust.
Standard 1.75" Vanity Drain
The center opening takes a standard 1.75" bathroom drain without overflow, so matching pop-up drains in several finishes fit; the drain is sold separately.

Installation & Care
Installation
This vessel sink sits on top of the vanity countertop, so no cabinet cutout beyond the drain hole is needed. Following Nantucket's vessel guide, dry fit the bowl, leave at least 5" behind it for the faucet, and cut a 5" diameter hole on the drain center; the sink has no faucet holes, so plan a tall vessel faucet on the deck or a wall-mount faucet. A bead of plumbing silicone bonds the base to the counter (sealant not included). The center drain takes a standard 1.75" vanity drain without overflow, since the sink has no overflow, sold separately. Nantucket recommends professional installation. The Vessel installation guide is in Resources.
Care
Clean the sink with a pH neutral soap and a soft cloth only, then rinse and wipe it dry; Nantucket requires pH neutral soap for Regatta Collection sinks. Do not use abrasive cleansers or pads, and keep improper or caustic cleansers off the glaze, since Nantucket's warranty does not cover glaze damage they cause. Fireclay will not rust.
