Pietra Grey Marble Sink

Custom Double Integrated Wall-Hung Marble Basin Pietra Grey Marble Double Integrated Wall Hung Sinks for Villa and Hotel Bathrooms The reference product presents a long double-basin composition with two rectangular sink cavities, a dark charcoal-grey surface, fine white mineral veins, and a vertically oriented front fascia. This configuration gives the bathroom a cleaner architectural line than a conventional countertop fitted with two separate ceramic basins. The visible floating effect depends on a properly engineered wall-support system, accurate plumbing coordination, controlled stone fabrication, and installation by experienced contractors.

Product Overview of Natural Grey Marble Integrated Vanity Sinks

Pietra Grey Marble is recognized for its deep charcoal-grey to graphite background, crossed by fine white or pale-grey linear veins. The restrained contrast works particularly well in contemporary bathrooms using warm timber, matte-black metal, brushed brass, bronze, smoked glass, microcement, light plaster, or pale stone wall finishes.

The uploaded reference shows a long rectangular double-sink form with two deep basin cavities and a substantial full-width front fascia. The front panel visually conceals much of the basin depth and supporting structure, allowing the completed installation to read as one floating architectural volume.

The phrase integrated describes the coordinated relationship between the countertop surface, basin cavities, front fascia, drainage zones, and wall-mounted structure. Depending on the final fabrication method, the unit may contain carefully controlled stone junctions or concealed assembly interfaces. It should not be assumed to be carved from one solid block unless the approved production drawing explicitly confirms that construction method.

Natural marble varies in background tone, vein direction, vein concentration, crystalline areas, fissures, mineral marks, and repaired sections. Every finished basin therefore has an individual pattern. KA UNITED can select and lay out the stone so the top, basin interiors, front fascia, and exposed sides remain visually coordinated.

The misspelled sourcing phrase Pietra Grey Marble Vaity Sink is sometimes used in product searches. All quotations, shop drawings, piece labels, and approvals should use the confirmed product name and drawing code to avoid specification errors.

Dark Grey Marble with Fine Linear Veining Pietra Grey provides a more restrained stone pattern than brecciated marble or strongly veined Calacatta. Its fine white lines remain visible against the dark base without overwhelming the sink's long architectural profile. The uploaded reference uses directional veins across the top, basin areas, and front elevation. A controlled cutting layout can preserve related movement between adjoining surfaces, although perfect uninterrupted matching cannot be guaranteed across every fabricated component. A honed finish softens reflections and gives the grey background a more tactile appearance. Polishing deepens the dark tone and increases vein contrast but may also make water marks, fingerprints, and cleaning streaks more visible. The selected finish should be approved beside the intended faucet, wall tile, cabinet material, mirror, and bathroom lighting.

Integrated Double-Basin Geometry in Pietra Grey Marble

Pietra Grey Marble Integrated Sinks combine the visible countertop, basin zones, and front profile into one coordinated stone composition. This reduces the visual separation commonly seen between a conventional vanity top and two independently installed ceramic basins.

The two basin cavities can be centered symmetrically or adjusted according to faucet positions, mirror widths, user spacing, concealed plumbing, wall structure, and the overall vanity layout. Basin length, width, depth, bottom slope, corner radius, overflow provision, and drain position must be shown on the approved shop drawing.

The front and rear basin rails require adequate width for fabrication, handling, sealing, and long-term support. Narrow stone sections should be avoided unless reinforcement and structural support have been properly designed.

A concealed drain concept can provide a cleaner interior appearance, but the removable cover, drainage gap, water flow, trap access, cleaning method, and replacement access must remain practical.

The basin floor must direct water toward the drain without creating low areas where residue can collect. Drainage performance should be checked before dispatch and confirmed again after installation.

 

Floating Installation and Concealed Support Pietra Grey Marble Floating Sinks create open floor space beneath the basin and can make a large bathroom appear visually lighter. The floating effect is architectural, but the support structure behind the wall must be substantial. The support design may include a concealed steel frame, wall brackets, structural rails, embedded anchors, or a project-specific combination. Support points must avoid interference with basin cavities, drain outlets, faucet hoses, traps, and maintenance access. The wall finish should not carry the stone load. Tile, plasterboard, decorative panels, and waterproof membranes are finish layers rather than structural supports. The installation drawing should define finished height, bracket locations, wall penetrations, basin level, plumbing route, front-fascia clearance, and access for future maintenance. Final structural calculations and anchor selection remain subject to the project engineer, wall construction, local codes, and actual finished basin weight.

Show concealed steel support, wall brackets, rear fixing zones, basin underside, drain access, or the installed floating profile.

Faucet, Drain, and Plumbing Coordination of Marble Bathroom Basins

Pietra Grey Marble Basins can be prepared for deck-mounted or wall-mounted faucets. Deck-mounted layouts require confirmed hole diameter, center spacing, spout reach, handle clearance, basin center, rear-deck width, and access beneath the stone.

Wall-mounted faucets remove drilling from the countertop but require precise coordination between the concealed valve, finished wall thickness, spout reach, basin centerline, mirror position, waterproofing, and future service access.

Each basin needs an independently accessible drain and trap arrangement unless a project-specific shared drainage system has been engineered. Plumbing must remain serviceable after the front fascia and wall finish are installed.

Overflow openings, pop-up wastes, removable stone drain covers, linear channels, and hidden outlets should be approved together with the sink geometry. A decorative drain solution must not prevent cleaning or emergency access.

The stone fabrication drawing and plumbing drawing should use the same centerlines, finished wall references, outlet heights, and installation levels.

Pietra Grey and Recommended Floating Basin Comparison

Material Selection and Production Risk Control

• Approve current slab photographs showing the complete charcoal-grey background, vein direction, fissures, natural marks, repairs, and usable dimensions.
• Confirm the reference dimensions as overall length, depth, and visible height in the final millimetre drawing.
• Define both basin centers, cavity dimensions, depth, slope, corner radii, overflow requirements, and drain positions before cutting.
• Provide final faucet models, hole diameters, center spacing, spout reach, valve positions, and accessory requirements.
• Confirm whether the unit uses visible drains, concealed outlets, stone drain covers, or another custom drainage system.
• Review the stone construction method and do not describe the basin as carved from one solid block unless the approved production design confirms it.
• Coordinate top, basin, front-fascia, and side-piece vein directions through a numbered cutting layout.
• Engineer the concealed frame, wall anchors, bracket positions, support rails, and fixing points for the actual finished weight.
• Confirm that plumbing, traps, drain connections, faucet hoses, and shutoff valves remain accessible after installation.
• Approve the honed or polished sample under representative bathroom lighting before full finishing.
• Complete a factory water-flow check, dimensional inspection, dry assembly review, surface inspection, and support-interface check before packing.
• Retain approved matching marble for site damage, future repair, replacement components, or installation adjustments.

Project Specification Summary of Marble Sinks

Packing, Delivery, and Site Handling

A long double marble basin requires reinforced packing that supports the top, basin rails, front fascia, exposed corners, and any concealed joint interfaces without placing pressure on vulnerable sections.

The unit may be packed as one completed assembly or as numbered coordinated components, depending on finished weight, structural safety, container access, building access, lifting method, and installation design.

Basin cavities, faucet holes, drain openings, narrow rails, front corners, and projecting fascia edges must never be used as lifting points.

Crate labels should identify the project, room, basin code, orientation, top side, front elevation, support points, component list, and installation drawing reference.

Before dispatch, confirm forklift capacity, crane or lifting-frame requirements, crate dimensions, doorway widths, elevator capacity, corridor turns, temporary storage, wall readiness, and the sequence in which the basin will be installed.

Care and Maintenance

Clean the marble with clean water, a soft non-abrasive cloth, and a pH-neutral product formulated for natural stone. Remove dust and abrasive particles before wiping the dark surface.

Blot cosmetics, perfume, hair dye, toothpaste, soap residue, oils, colored liquids, and standing water promptly. Dark honed or polished marble can make dried water marks, limescale, fingerprints, and cleaning residue more visible.

Avoid vinegar, citrus cleaners, aggressive descalers, abrasive powders, rough pads, concentrated solvents, and unapproved acidic or alkaline bathroom chemicals. Pietra Grey is natural marble and can etch from acidic exposure.

A compatible penetrating sealer can reduce absorption and provide additional time for cleaning. It does not make the marble waterproof, stain-proof, acid-proof, scratch-proof, limescale-proof, or maintenance-free.

Clean removable drain covers and concealed channels regularly so soap residue, hair, and mineral deposits do not obstruct water flow. Do not use metal tools that can scratch the basin interior.

Inspect the wall fixings, support frame, drain joints, faucet penetrations, flexible sealant, plumbing connections, stone junctions, and surface condition periodically. Movement, persistent moisture, or drainage problems should be corrected at their source.
