Wall mounted cabinets look simple on a drawing: a box fixed to a wall, some shelves inside. In project procurement, they are also a frequent source of site problems, because the wall, the fixing method, the services behind the wall and the cabinet itself are often supplied by different parties. This guide sets out what procurement teams on villa, hotel and apartment projects should record before a wall mounted cabinet order is placed, so that shop drawings, quotations and site conditions all describe the same job.

Start With the Wall, Not the Cabinet

A wall mounted cabinet carries its own weight plus contents, suspended entirely from the substrate. The first document on file should therefore state what the cabinet is fixing into. Record the wall construction on each elevation: masonry, blockwork, lightweight partition with stud centres, timber framing, or a finished surface such as a decorative wall panel or cladding system that sits in front of the structural wall.

For lightweight partitions, note the stud layout and the load rating the partition can accept. Where a heavy full-height unit is specified on a partition, the drawing should show whether reinforcement or a structural backing frame is required, and name the party responsible for providing it — the wall contractor or the joinery supplier. This single line item, often left blank, is the most common source of change orders once installation begins.

Specify the Unit as a Make-to-Measure Product

On most fit-out projects the cabinets are not catalogue sizes. Our wall mounted cabinets in the Storage Units range, for example, are supplied with made-to-measure sizing, selectable materials and finishes, and a layout matched to the space, and the same configuration approach applies across our wall mounted sideboards and wall mounted display cabinets. The point for procurement is that a make-to-measure item cannot be value-engineered on site; it has to be fixed on paper.

The document set for each unit type should carry: overall height, width and depth with a tolerance stated; the carcass material and its moisture rating where the unit sits in a bathroom, laundry or other wet area; door and drawer front material and finish, quoted against a named sample reference rather than a colour name; edge treatment; internal configuration, including shelf spans, hanging-rail positions and drawer sizes; and the door or hardware schedule, with opening direction and clearance to adjacent finishes.

Where lighting, integrated mirrors or appliance cut-outs are involved — as in our integrated cabinet lighting line — record the driver location, the access route for maintenance, and the electrical contractor's obligation to bring a feed to that point. Storage that only works when powered or ventilated should appear on both the joinery and services drawings.

Record Wall Services Before Shop Drawings Are Signed

A fixing bolt that strikes a concealed pipe, a shower valve or an electrical back box is a demolition problem, not a joinery problem. The procurement file should include coordinated wall services drawings for every wall with a mounted unit, and the shop drawing should show a clear fixing zone where no services are run. Where that is not achievable, the document should record an alternative fixing detail — an approved batten frame, an anchor plate, or a change in unit position — agreed before manufacture.

In bathrooms and laundries, also record waterproofing continuity. Any fixing that penetrates a tanking layer needs the waterproofing contractor's method statement and, for wet areas, the penetration detail signed off by the same party that will certify the work.

Lock Down the Measurement and Tolerance Basis

For imported custom joinery, dimensions must be taken from finished wall faces, not structural ones. The file should state who performs the site survey, at what stage — after plaster, tiling and floor finishes are complete — and which survey is authoritative if a site dimension differs from the drawing. Where a unit is designed into a recess, record the finished dimensions of the recess and the intended shadow gap or joint detail.

Where the design intent is a wall-integrated, flush look, as in full-height custom wall cabinetry, the tolerance discussion belongs in the quotation stage, not at handover. Our arched niche and full house custom wall cabinet project shows this working as a single package, where site measurement, 3D rendering, manufacturing and on-site installation are coordinated by one supplier and the panel material, colour and storage layout are fixed against the rendered design.

State What the Quotation Covers

Comparison between suppliers only works when the inclusions are written down. For wall mounted cabinets, the quotation schedule should list: the fixing system and anchor type; packing, crating and the pack list; freight mode, incoterm and delivery point; on-site installation, including who supplies the installer; snag and punch-list rectification; warranty scope and exclusions; and spare parts availability, such as replacement fronts, hinges and drawer runners. Custom units ordered in phases should carry the finish reference and production batch of the first order, so later batches can be matched.

For multi-apartment or guest-room work, record unit numbers against each cabinet type, so a variation on one room type can be priced and tracked without re-measuring the whole project.

Keep One Document That Closes the Loop

The most useful deliverable is a single cabinet schedule per wall type, signed by the designer, the wall contractor and the joinery supplier, that carries the substrate, the load and fixing method, the survey dimensions, the finish reference, the services clearance zone and the installation responsibility. When that one page exists before manufacture starts, wall mounted cabinets stop being a site problem and become a straightforward line on a delivery note.

SANTERSON manufactures custom cabinetry, wall-mounted storage and building finishes for villa, hospitality and office projects, with site measurement, 3D rendering, production, freight and installation coordinated under one supplier. Send us your cabinet schedule and wall drawings, and we will quote the units against your project's dimensions and finishes.
