Flandes Grey Marble Vessel Sink 16"x16"x5.9" (40x40x15 cm) — CBC40

Flandes Grey Natural Marble Vessel Sink — Rough Exterior and Polished Interior — Hand-Carved — 40 x 40 x 15 cm (16 x 16 x 6 in) | CBC40

The CBC40 natural marble vessel sink is a handcrafted piece of singular elegance, hand-carved from a single block of natural grey marble carefully quarried in the mountain regions of Southeast Asia (Indonesia). Measuring 40 x 40 x 15 cm (16 x 16 x 6 in), weighing 20 kg (44 lb) and finished in the Flandes grey tone, a sophisticated neutral grey with unique natural veins, this countertop vessel sink features the classic finish of the line: a natural rough exterior and a polished interior. The contrast between rustic and refined is ideal for sophisticated powder rooms, en-suite bathrooms, rustic chic projects and contemporary architecture with an organic touch.

Flandes grey marble is one of the most versatile and sought-after tones in natural marble. Its sophisticated neutral grey works with a wide range of interior styles, from the most minimalist and modern to refined rustic. Every sink is absolutely one of a kind: the variations in color, veining and texture can never be repeated, so no one else in the world owns a sink exactly like yours. It is one of the natural marble sinks most often specified by architects and interior designers for high-end contemporary projects.

Dual finish — natural rough exterior and polished interior

What sets the CBC40 sink apart is the sophisticated contrast between two finishes that complement each other perfectly. The exterior preserves the rustic, natural texture of the marble, exactly as the stone came from nature, with organic edges, authentic irregularities and the raw beauty of grey marble in its original form. The interior, by contrast, is fully polished, revealing a soft, elegant sheen that highlights the natural veins of the Flandes grey while ensuring easy cleaning and comfort in daily use.

This balance between rustic and refined creates a piece that is at once a natural sculpture and a thoroughly functional object. Unlike our fully polished sinks, it has an organic presence and tactile texture that pairs perfectly with wood or natural stone vanity tops and with rustic chic, Mediterranean and contemporary projects with an artisanal touch.

Flandes grey marble — natural elegance from Southeast Asia

The grey marble used in this sink comes from the mountain regions of Southeast Asia, where nature worked for thousands of years to create a stone rich in texture, organic veining and tones that are impossible to reproduce artificially. Flandes grey is a sophisticated neutral grey of exceptional versatility: it works with a wide range of interior styles, from the most minimalist and modern to refined rustic, as well as industrial and Scandinavian projects.

Because it is a natural material, each piece shows unique variations in color, veining and texture, along with possible small micro-fissures and natural marks: authentic traits of the raw material that reinforce the exclusive character of the sink. Unlike mass-produced ceramic, porcelain or resin sinks, natural marble does not lose its color, does not peel and gains even more character with time, becoming a true heirloom in your home.

Who is this sink for?

• Rustic Chic and Mediterranean Projects: The raw exterior texture pairs beautifully with solid wood, natural stone and earthy tones, the essence of refined rustic style.

Which faucet goes with this Flandes grey sink?

Because this is a countertop vessel sink in polished grey marble, the choice of faucet is essential to bring the set together and highlight the contemporary look of the piece:

• Tall vessel faucet (recommended): Delivers a comfortable, centered flow of water without splashing; minimum height of 22 cm (8.7 in) for a sink of this size.
• Wall-mounted faucet: A clean, sophisticated look that frees up counter space, a perfect match for the minimalist aesthetic of Flandes grey.
• Matte black: Creates an elegant monochrome composition with the grey of the marble, the ideal choice for contemporary projects.
• Chrome and brushed nickel: Reinforce the contemporary aesthetic, ideal for modern, minimalist bathrooms.
• Brushed gold: Creates a warm, sophisticated contrast with the neutral grey of the marble, a touch of classic luxury.
• Aged bronze: For projects that blend the contemporary (polished marble) with refined rustic (aged metal).

How to care for your marble sink

• Regular cleaning: A soft cloth or gentle sponge with water and mild soap keeps the surface clean without harming the marble.
• Avoid harsh products: Never use acids, bleach, solvents or abrasive products; they can stain and damage the finish of the marble.
• Dry after use: Avoid standing water to preserve the natural sheen and prevent stains.
• Periodic sealing: Apply a sealer made specifically for marble every 6 to 12 months to protect against moisture and liquid absorption.
• Watch out for pigmented substances: Makeup, creams and colored soaps can stain the marble if they are not cleaned off quickly.
• Do not use rough sponges: Choose soft cloths to avoid scratching the polished interior.
• Protect from impacts: Marble is resistant, but heavy objects can cause cracks or chips.

Expert Tip: The raw exterior of this sink has a natural texture with exposed micro-pores, so sealing is especially important to preserve its appearance and prevent staining. Apply a sealer formulated for marble every 6 months, paying special attention to the rough outer surface. This seals the natural pores and keeps the organic character of the Flandes grey alive and protected for much longer.
