Squared rectangular basin below the counter
The basin sits beneath the countertop, leaving the counter edge exposed around the bowl. Water and cleaning cloths can move across that edge into the basin without passing over a raised sink rim. The bowl, cutout and supporting arrangement form one installation; a countertop opening by itself does not support the basin.
A more angular bowl continues the straight lines of a rectangular vanity and countertop opening. Softer internal corners give a different transition between the side walls and bowl floor. The two profiles share an undermount installation, but their corner geometry changes the opening and the areas reached when wiping the bowl.
The basin can be ordered with matching waste fittings and a stone, quartz or solid-surface vanity top; faucet, cabinet and mirror are scheduled as extras unless included. Basin support and the rim joint are detailed for that bowl and countertop.
The outside basin envelope, usable bowl and countertop opening are three different outlines, and a square-corner counter opening may not match a rounded bowl below. The profile carries through to the counter edge and corner radius, so bowl and top are chosen together.
An overflow channel needs a waste fitting that takes water from it, and a basin without overflow uses the matching no-overflow waste. These are plumbing choices, apart from the drain-cap finish, so the order lists basin and waste as a pair.
Faucets mount through the surrounding top or on the wall. A single-handle faucet needs a different hole layout from a widespread set, and spout reach, handle travel and the distance behind the bowl decide whether the fittings work with the chosen opening.
| Installation | Undermount basin below the countertop, with the basin rim concealed. |
|---|---|
| Bowl profile | Custom rectangular undermount basin with a more angular internal bowl profile and a concealed rim below the countertop. |
| Basin geometry | Rectangular bowl with angular or softly radiused internal corners; shape and depth are custom order variables. |
| Countertop interface | Stone, quartz or solid-surface top; opening outline, edge and support detailed for the selected basin. |
| Overflow & waste | Overflow channel available as an order choice; waste fitting matched to the actual overflow arrangement. |
| Faucet arrangement | Counter-mounted single-handle or widespread set, or a wall-mounted faucet; tap holes are separate from the basin opening. |
| Order dimensions | Overall width, front-to-back depth, bowl depth and rim details recorded for the selected basin; no universal cutout dimension. |
| Minimum order | Quoted per model at your project quantity. Where a factory model has a production minimum, the quotation states it; small quantities can ship with the rest of your project in one container. |
| Standards & certificates | Matched to the ordered model: tell us the standards or certificates your market or project requires, and we confirm in writing which documents are available for this configuration before you order. |

Overall basin size is not a cutting template. The layout places the full basin below the counter and records the opening as its own outline, allowing for counter edges, backsplash depth and any adjacent bowl, and fabrication uses the basin's actual rim and internal corners.
A deeper bowl lowers the waste and trap into the cabinet. Drawers, shelf positions and cross rails must leave room for that assembly and access to its connections. An open cabinet or a drawer with a plumbing recess offers different storage below the same countertop layout.
Repeated rooms can share a bowl profile and drain finish with room-specific countertop and faucet positions. Left, right or centered placement changes the cabinet and plumbing layout, and a double-basin top needs two complete bowl and waste positions.
The basin schedule records the rectangular profile, overall dimensions, bowl depth and number of fixtures. One configuration repeated across rooms keeps the list simple, and each different bowl profile or depth gets its own order line, even in the same color.
A basin-only quotation is separate from a fabricated vanity top. The top adds material, cutting, opening-edge finishing, faucet holes and any backsplash or side return. Two basins in one top require two openings and their associated plumbing space.
The selected overflow arrangement determines the compatible waste. Faucets and their rough-in or flexible connections are separate from the basin body.
Basin bodies and fabricated tops are protected at rims, corners and openings, and the packing list keeps fixtures, waste fittings and large top pieces apart. Counter installation, basin support, sealing and final water connections are site tasks with their own prices. Tell us the rooms and quantities and we will put this on one quote with everything else you are ordering, and show you what fits in a container.
It is an undermount basin: the bowl fixes below the countertop with its rim hidden, so the counter edge frames the opening. A drop-in sink has a rim that rests on top of the counter and needs a different installation detail.
Both retain a rectangular footprint. Squared corners give a more angular internal profile; radiused corners soften the transition between the bowl walls and floor. The chosen profile affects the countertop opening and the spaces reached during cleaning.
Outside width and depth describe the whole basin; the opening in the top follows the bowl geometry and rim relationship. Faucet holes, edge finishing and support are coordinated with it.
Yes. The waste must suit the basin's overflow arrangement: an overflow channel needs a fitting that takes its water, and a no-overflow basin uses the matching waste. The drain-cap finish is chosen on its own.
It can work with drawers when the cabinet leaves room for the full bowl, waste and trap, which depend on bowl depth and drain position. A plumbing recess or a different drawer layout may be needed, so the cabinet is drawn around the basin itself.
Yes. A coordinated package can include the basin, vanity top, cutouts, waste and faucet. The schedule identifies the included components and their locations. Cabinetry, mirrors and installation are separate items unless they appear in the same quotation.
