Rectangular Basin Essentials

Rectangular Stone Sink Small

Calacatta Viola rectangular vessel sink in warm white marble with red-purple veining and matte honed finish.

A Rectangular Marble Basin should be sized from available vanity width, faucet reach and comfortable splash clearance rather than visual preference alone. Natural stone is durable when properly fabricated, and vessel-style installation is possible when the base and waste geometry are designed for countertop mounting. Match the waste to the fabricated drain opening, assess sealing for the exact stone and clean this Rectangular Stone Basin with non-acidic products.

Vessel Dimensions & Drain Fit

Choosing the Right Rectangular Vessel Format

A 50 × 35 × 12 cm vessel basin provides a relatively shallow profile, so faucet height and spout projection should be selected to minimize splashing while still clearing the rim. The 19 kg solid-marble body also requires a countertop capable of supporting concentrated weight around the drain opening. For custom fabrication, confirm the waste diameter, overflow requirement and tap location before carving because altering a finished Calacatta Viola basin later carries a significant chipping risk.

Start With Vanity Width

Sizing a Rectangular Marble Vessel Sink Correctly

At 50 × 35 × 12 cm, this vessel basin needs a vanity deep enough to leave usable countertop in front of and behind the bowl rather than forcing it against the wall or front edge. The faucet should clear the 12 cm rim comfortably and project far enough for the stream to land well inside the 35 cm basin depth, while sufficient space around the bowl helps control splash and makes cleaning easier; vanity depth, tap reach and basin position should therefore be planned as one layout.

Fabrication & Drainage

How a Rectangular Natural Stone Basin Is Built

A rectangular natural-stone basin can be carved from a sufficiently thick block or fabricated from carefully prepared stone components, but either method must create a continuous bowl slope toward the drain while maintaining safe wall and rim thickness. Installation then depends on a level bearing surface, accurately aligned waste fitting and enough support beneath the 19 kg basin so its load is not concentrated around only a few points.

Waste Fit

Drain Compatibility for a Marble Countertop Sink

Confirm the exact waste and drain-opening diameter before carving the basin so the selected fitting matches without enlarging the marble on site.

Tap Position

Faucet Reach for a Rectangular Vessel Basin

Position the spout so its stream clears the rim and lands well inside the 50 × 35 cm bowl instead of striking an edge and increasing splash.

Custom Stone

Made-to-Measure Veined Marble Washbasins

The 50 × 35 cm basin can be custom fabricated in alternative dimensions, natural stones and finishes to suit the vanity layout and intended visual character.

Product at a Glance

Calacatta Rectangular Basin Product Details

This basin uses Fine Matte Honed Italian Veined Marble in Warm White with Red-Purple Veining, measuring 50 × 35 × 12 cm and weighing 19 kg. The rectangular vessel format is designed for countertop use where vanity width, faucet reach and waste geometry are coordinated before fabrication.

Internal Bowl Length	Approx. 440 mm internal bowl length within the 500 mm overall basin.
Internal Bowl Width	Approx. 290 mm internal bowl width within the 350 mm exterior depth.
Internal Bowl Depth	Approx. 80 mm usable internal bowl depth within the 120 mm-high basin, retaining sufficient stone thickness beneath the waste area.
Corner Radius	R25 mm internal bowl corners for easier cleaning and drainage, with R5 mm eased external corners to reduce edge chipping.
Waste Opening Diameter	Ø45 mm waste opening located at the bowl’s lowest point, compatible with a standard 1¼-inch unslotted vessel waste.
Overflow Provision	No integral overflow channel; use an unslotted 1¼-inch free-flow waste through the Ø45 mm opening.
Rim Width	Approx. 30 mm continuous rim width around the 440 × 290 mm internal bowl within the 500 × 350 mm exterior.
Underside Bearing Area	Minimum 420 × 270 mm continuous underside bearing area around the drain zone, supported on a level vanity substrate with stone-safe silicone isolation.
Counter Contact Footprint	Approx. 440 × 290 mm continuous countertop-contact footprint beneath the 500 × 350 mm vessel, surrounding the central waste clearance.
Splash Radius	R25 mm internal splash radius at the basin floor-to-wall transition, directing water inward and eliminating difficult-to-clean sharp corners.

Counter Support

Installing a 19 kg Stone Vessel Sink

The 19 kg Calacatta Viola vessel requires a rigid, level countertop with continuous bearing around its base rather than isolated contact points. Confirm the drain opening and waste alignment before fabrication, and transport and lift the basin with two-person handling and padded support to protect its corners.

Built Around Clean Geometry

Why Choose a Rectangular Marble Wash Basin

A rectangular marble wash basin makes efficient use of vanity width while providing a broader linear washing area than a small round vessel. Its straight geometry suits countertop installation, dimensions can be tailored around faucet reach and splash clearance, and the drain opening can be fabricated to match the selected waste fitting before installation.

Defined Linear Shape
The 50 × 35 cm rectangular form creates a clearly defined linear wash area suited to contemporary vanity layouts.
Custom Drain Position
The drain opening can be positioned during fabrication to align with the selected waste assembly and vanity layout.
Solid Stone Construction
The 19 kg basin is fabricated from genuine Calacatta Viola marble, giving the rectangular form substantial natural-stone construction.
Flexible Countertop Placement
The 50 × 35 cm vessel can be positioned across compatible vanity tops wherever counter depth, faucet reach and drain alignment are correctly planned.

Surface Protection

Caring for a Honed Stone Bathroom Sink

A honed stone bathroom sink should be assessed for sealing according to the actual marble absorption and use, rather than treated on a fixed timetable. Clean the basin with pH-neutral, non-acidic products and avoid vinegar, citrus or harsh descalers that can alter the matte surface, especially when coordinating the basin with moisture-resistant finishes such as wet wall panels.

FAQCommon questions about this product.

What faucet spout reach should I choose for this rectangular Calacatta Viola vessel basin so the water lands comfortably inside the bowl without overshooting the drain or splashing the rim?

Choose a spout whose water outlet lands near the basin’s centre, usually about 100–150 mm inside the inner rim for a 50 × 35 cm vessel; depending on tap position and wall thickness, this commonly requires roughly 150–200 mm spout reach, but template the exact faucet so the stream does not hit the near wall, overshoot the waste or strike the drain directly at excessive pressure.

Should the bottom of a rectangular stone sink be flat or continuously sloped for complete drainage?

The bowl bottom should have a continuous fall toward the waste rather than a completely flat surface, which would retain water and soap residue. A slope of approximately 1–2% is a useful fabrication target, shaped without abrupt low spots and checked with a water test before delivery; the drain flange should finish flush with or slightly below the surrounding bowl surface.

What continuous bearing area and vanity reinforcement are required beneath this 19 kg Calacatta Viola vessel sink to prevent unsupported stone around the drain?

The 19 kg vessel sink should bear continuously on a flat, rigid, waterproof vanity surface around its designed base rather than resting only at corners or on the drain fitting. Reinforce the deck with framing beneath the footprint, provide manufacturer-approved bedding and leave the drain area accurately relieved so tightening the waste assembly does not pull unsupported marble into tension.

Should the exact drain assembly be selected before fabricating the waste opening in a rectangular stone sink?

Yes, the exact drain assembly should be selected before fabricating this Calacatta Viola sink because the waste-hole diameter, flange width, thread length and overflow configuration must match the fitting precisely. An oversized opening may leave inadequate sealing support, while an undersized or incorrectly shaped opening may require risky site drilling through the finished marble. Provide the fabricator with the physical drain or its verified technical drawing, confirm whether the basin has an overflow and complete all machining before the 50 × 35 cm basin is polished and delivered.

How should the internal slopes and corner radii of the Rectangular Stone Sink be fabricated so water drains completely instead of collecting in its corners?

Fabricate a continuous fall from every internal surface toward the drain, using generous radiused corners rather than sharp 90-degree intersections. A physical or digital water-flow test should confirm no low spots remain, while the waste flange must sit at or slightly below the finished basin surface so it does not form a retaining lip.
