Trough Basin Planning

Marble Trough Sink Small

Calacatta Viola trough sink in ivory white marble with deep wine veining and a low-sheen honed finish.

A Marble Trough Basin is a long shared basin that can accommodate two faucet positions when width and drainage are designed accordingly. Wider models work particularly well as a Double Marble Basin, but their stone mass requires engineered cabinetry, brackets or wall framing rather than ordinary lightweight supports. Wall mounting is possible with suitable structure; specify faucet centres, waste location, sealing and reinforcement before fabrication.

Dual-Faucet Layout & Support

Designed for Single or Shared Wash Areas

An 80 × 40 cm trough can serve one generous wash position or a compact shared setup, but a true two-user layout requires faucet spacing that gives each person usable elbow room. The 45 kg marble body needs continuous counter support or appropriately engineered wall brackets, and the long bowl should be fabricated with sufficient fall toward the drain to prevent standing water. Integrated backsplashes can also reduce joints around frequently wet areas.

Calacatta Viola trough basin with two wall faucets and shared wash zones — Calacatta Viola trough basin creates two compact wash zones with carefully spaced wall-mounted faucets.

Single or Shared Use

Planning an 80 cm Marble Trough Basin

An 80 × 40 cm trough basin can be planned as one generous washing station or as a compact two-faucet arrangement, but those are different fabrication decisions. For a single user, one centred tap gives generous elbow and splash space across the long bowl; for two users, faucet centres must leave realistic personal space and the internal slope and waste layout must drain both positions effectively, so two taps should not be added simply because the basin is 80 cm wide.

Drainage & Support

How a Long Stone Wash Basin Should Be Engineered

A long stone trough should be engineered so the bowl floor has a controlled fall toward the chosen waste location rather than allowing water to sit across its 80 cm length. The drain may be centralized or positioned to suit the plumbing design, but the slope must lead consistently to it. At 45 kg, the basin also needs substantial cabinetry, brackets or wall framing that supports the full span instead of only the ends.

Faucet Centres

Two-Tap Layout for a Double Marble Basin

Space the two faucet centres so each user has a distinct wash zone and each water stream lands comfortably within the shared trough.

Wall Support

Mounting a 45 kg Marble Trough Sink

The 45 kg trough requires engineered wall brackets or reinforced cabinetry that supports its full length rather than relying on lightweight vanity construction.

Water Fall

Drain Slope in a Long Stone Basin

Shape the internal trough with continuous fall toward the waste so water from both faucet zones drains without remaining in flat sections.

Product at a Glance

Calacatta Trough Sink Product Details

This trough sink uses Low-Sheen Honed Calacatta Natural Marble in Ivory White with Deep Wine Veins, measuring 80 × 40 × 15 cm and weighing 45 kg. Its elongated format supports a shared wash zone or two faucet positions when the waste, internal fall and structural support are designed accordingly.

Internal Trough Length	Approx. 740 mm internal trough length, leaving robust end walls within the 800 mm exterior length.
Internal Trough Depth	Approx. 100 mm usable internal trough depth.
Faucet Centre Spacing	Two faucet positions at 300 mm centre-to-centre spacing, symmetrically arranged over the 740 mm internal trough for balanced shared use.
Waste Outlet Count	Two Ø45 mm waste outlets, positioned symmetrically beneath the shared 740 mm trough to prevent slow drainage across its full length.
Waste Outlet Diameter	Two Ø45 mm waste outlets positioned symmetrically along the 740 mm internal trough for balanced drainage.
Overflow Provision	Concealed linear overflow slot centred on the rear internal wall and connected to the waste system; final geometry must follow the selected waste assembly.
Internal Fall Gradient	Approx. 2% continuous fall toward the two waste outlets, producing roughly 7–8 mm drainage drop across each half of the 740 mm trough.
Underside Reinforcement	Two concealed stainless-steel reinforcement rails beneath the 800 mm length, positioned approximately 100 mm inward from the front and rear edges and isolated from the marble with structural epoxy.
Bracket Spacing	Three concealed heavy-duty brackets at approximately 300 mm centres across the 800 mm length, with outer brackets set about 100 mm from each end.
Shared Wash-Zone Width	Approx. 650 mm clear shared wash-zone width within the 800 mm trough, suitable for two compact user positions while retaining substantial stone at both ends.

Installation Choices

Wall-Mounted, Countertop or Console Trough Basin

A countertop installation needs continuous engineered cabinet support beneath the 45 kg trough, while a wall-mounted version requires structural blocking and concealed brackets; a console can transfer the load through a dedicated metal or stone frame. Coordinate rear or side splashes with the selected taps, wall junction and cleaning access before fabrication.

Designed for Wider Vanities

Why Choose a Marble Trough Washbasin

A marble trough washbasin provides an extended shared washing surface, can accommodate two faucet positions when correctly designed, works as a double-basin alternative without dividing the bowl, and can be specified for countertop, console or engineered wall-mounted installation according to the required support.

Single or Double Use
The 80 cm trough can serve one user comfortably or accommodate two faucet positions when drainage is designed accordingly.
Custom Faucet Centres
Faucet centres can be customized during fabrication for single-user or coordinated double-tap configurations.
Integrated Long Bowl
The 80 cm elongated bowl creates one continuous washing area that can accommodate coordinated single- or double-faucet layouts.
Engineered Stone Presence
The 45 kg Calacatta construction gives the elongated basin a substantial architectural presence that requires properly engineered support.

Stone Maintenance

Caring for a Honed Marble Trough Sink

Maintain the honed marble trough sink by sealing only where the stone's absorption requires additional stain protection, then cleaning with a mild pH-neutral product rather than acidic bathroom chemicals. Because the 80 cm bowl holds a broader wet area, wipe standing water and residue regularly along the base and corners, following the same care discipline expected in professional marble tile installation ontario.

Technical Overview

Marble Trough Basin Specifications

Use the trough-basin specifications to confirm faucet count, drain position, mounting method and structural support before fabrication. These fields are especially important for shared or double-faucet layouts where the long marble basin must be supported evenly across its full span.

FAQCommon questions about this product.

Can two faucets on this Calacatta Viola trough basin share one central waste effectively, or is a separate drain position needed for each user area to improve drainage?

Two faucets can share one central waste on an 80 cm trough only when the basin floor slopes continuously from both user zones toward that drain without flat areas; for heavier simultaneous use, two wastes or a long concealed channel provide faster, more even drainage, so test the fabricated fall and expected combined tap flow before approving a single central outlet.

How should faucet centers be positioned on a marble trough sink designed for two simultaneous users?

For two users across this 80 cm trough, position the faucet centres symmetrically on either side of the basin centreline, commonly about 300–400 mm apart depending on spout width and user space. Each water stream should land inside its own washing zone and away from the central divider line or drain, while adequate edge distance must remain around faucet holes if the taps are mounted through the stone.

Does the 80 cm-long, 45 kg Marble Trough Sink require concealed stainless-steel rails or an engineered support frame to control bending and stress around the waste opening?

A 45 kg, 80 cm-long marble trough normally requires an engineered frame, continuous load-bearing deck or concealed stainless-steel rails rather than relying on cabinetry edges or the waste connection. Supports should carry the sink near its structural bearing zones, control deflection across its length and leave the drain unrestrained; final spacing and section sizes must be approved by the fabricator or structural engineer.

How should concealed wall brackets be sized and spaced to support a 45 kg marble trough sink safely?

Concealed brackets for this 80 × 40 cm, 45 kg marble trough sink should be engineered for the basin’s dead weight plus water, fittings and accidental user loading, normally using a substantial safety factor rather than designing for 45 kg alone. Multiple corrosion-resistant steel arms should support the basin near both ends and around concentrated load zones, with spacing coordinated to the drain and faucet positions; for an 80 cm span, two heavy-duty brackets may be the minimum, while three or a continuous steel frame can distribute load more reliably. Every fixing must terminate in reinforced concrete, masonry or engineered blocking—not tile or plasterboard—and the final bracket section, anchor diameter and embedment require approval by a structural engineer.

Can the backsplash and Marble Trough Sink be fabricated from sequential slab cuts so their veins continue naturally across the joint?

Yes, the trough and backsplash can be cut from sequential areas of the same slab and digitally laid out for vein continuity. Approve the joint position, face orientation and vein match before cutting; allow for the stone removed by the saw kerf and use a narrow, color-matched flexible joint rather than forcing the pieces into hard contact.
