A wall-hung basin looks simple on a drawing. It is a bowl, a bracket and a tap hole. The problems appear later, when the waste connection does not line up with the stud wall, when the tap reaches too far over the rim, or when the guest-room basins in one project were specified from three different ranges and no two sit at the same height. Model Wall Hung Ceramic Basin 1051B is a compact wall-mount sink in vitreous ceramic with a curved, minimalist profile and a back-panel fixing. It is well suited to apartments, boutique hotel rooms and villa bathrooms where floor space is scarce and the look has to stay clean. This article sets out what designers and buyers should agree on before that basin reaches site.

Start with the object in the drawing, not the picture

The 1051B is fixed to the wall through a back panel rather than carried on a vanity or a pedestal. That single decision drives most of the rest of the coordination. There is no cabinet under the bowl, so the floor beneath stays clear and mopping is straightforward, which is exactly why housekeeping teams in small hotel rooms favour this type of basin. It also means the load path, the concealed pipework and the trap all sit inside or behind the wall, and somebody has to have decided where they go before the wall is closed.

The published page for this model lists an overall size of 400 mm wide by 380 mm deep and 450 mm high, with a single tap hole reserved for a one-lever mixer. Confirm those figures against the current technical data sheet before they go into a tender document, because rough-in and dimension details are revised between catalogue printings. What matters in practice is that the designer and the buyer are working from the same drawing of the same model at the same point in time.

The four things that have to be agreed before order

1. Setting-out height and the clear zone in front

Wall-hung basins are set out by hand at each site, so the risk is inconsistency rather than error. Agree one rim height for a room type and hold it across the job — guest bathrooms, staff toilets, villa powder rooms — and put that dimension on the wet-area drawing, not in an email chain. Then check the clear approach in front of the basin against the accessibility rules the project is actually being signed off against. A compact bowl helps in tight rooms, but it does not create the required turning space on its own.

2. Waste and trap position

With no pedestal to hide a downward waste, the basin waste has to meet the wall outlet at the right height and depth. Confirm which trap arrangement the wall build allows, and confirm it against the current technical data sheet for this model before the framing goes in. Where a project mixes wall-hung basins with vanity-mounted ones, each family needs its own setting-out detail; borrowing one detail for both is a common cause of rework.

3. Tap selection and reach

The 1051B has one tap hole for a single-lever mixer, so the mixer is part of the specification, not an afterthought on site. Check three things together: the spout reach relative to the bowl depth, whether the spout clears the rim far enough to avoid splashing back onto the wall panel, and whether the tap body sits clear of the wall finish once tiling or panels are installed. A shallow wall basin and a long-throw spout are a poor pairing, and the mismatch only shows up after the tiles are on.

4. Wall build and fixing substrate

A back-panel wall basin needs solid backing at the fixing points. Timber stud work, steel framing and masonry each need a different blocking or frame detail, and tiled finished surfaces change the effective depth of the bracket zone. This is the item most often left open at quotation stage, because the basin price looks complete while the substrate cost sits in a different trade's bill.

Keeping a suite consistent across a project

Specifying one model per room type is what keeps a bathroom programme readable for the installer and consistent for the client. The 1051 range exists for exactly that reason: Wall Hung Toilet 1051W carries the same design language with a wall drain and concealed cistern arrangement, and where a stand basin is needed instead of a wall unit — a cloakroom, for instance, or a renovation that cannot open up the wall — Freestanding Pedestal Basin 1051S gives the same rounded profile on a floor-standing base. Mixing ranges within one floor plate is what makes a project look pieced together, and it multiplies spare-part and replacement work for whoever maintains the building afterwards.

All three are made in vitreous ceramic with a dense glossy glaze, which is the practical reason ceramics of this type hold up in high-use bathrooms: the surface resists limescale and water marking, and cleaning crews can work on it quickly without special products. Where a project needs a different look or a matching basin for a vanity run, single vanities and countertop basins from the same fit-out range can be coordinated at the same time as the wall-hung units.

What buyers should ask for in the quotation

A quotation that lists only a basin model number is not comparable between suppliers. Ask for the line to carry the model, the confirmed overall dimensions and tap-hole arrangement, the waste and trap configuration being supplied, the fixing bracket or carrier included with the unit, and the finish of the exposed waste set if one is used. Then ask which items ship in the same container as the rest of the bathroom package.

This last point matters more than it sounds on multi-trade jobs. SANTERSON works as a one-stop furniture and building materials supplier, supplying ceramics, vanities, cabinetry, lighting, flooring and wall finishes for the same project rather than leaving each category to a separate vendor. Fewer suppliers means one setting-out drawing set, one packing list and one point of contact when something arrives wrong — which is where most of the real saving on a bathroom package sits, not in the unit price of the bowl.

Customisation and project coordination

Where a design calls for something off the standard list — a different finish, a non-standard quantity band, or products matched to an interior scheme already agreed with the client — custom and OEM service covers bespoke finishes and manufacturing against project drawings. For a whole fit-out, the one-stop solution route runs from design consultation and space planning through material selection, production and quality control to site coordination and handover, with door-to-door delivery arranged alongside the rest of the package. Existing work in Melbourne, Sydney, Perth and North Turramurra shows this kind of combined furnishing and fit-out supply being used on Australian villa and apartment projects.

A short pre-order checklist

• Model and finish confirmed in writing, with the current technical data sheet attached to the purchase order.
• Rim height fixed per room type and shown on the wet-area drawing.
• Waste and trap arrangement confirmed against the wall build, not assumed from the product photo.
• Single-lever mixer selected, with spout reach checked against bowl depth and tile set-back.
• Backing or carrier detail resolved with the framing trade before the wall is closed.
• Matching suite items — wall WC, stand basin where needed — ordered together so one drawing set governs them.
• Delivery consolidated with the rest of the bathroom package, and a snag list agreed for handover.

Get those seven lines answered before the order is placed and a wall-hung basin stops being a site surprise. If you are specifying sanitary ware alongside cabinetry, lighting and finishes for one project, send the drawings and quantities to SANTERSON and the package can be quoted as a single coordinated supply.
