A single vanity looks like the easiest item on a bathroom schedule: one unit, one room, one line on the order form. In practice it is one of the most common sources of rework, because the vanity only works when the basin, countertop, mirror, lighting and rough-in plumbing all line up with it. This guide explains how to set quantities properly and how to coordinate the products around a single vanity, whether you are fitting out one apartment or ordering across a villa, hotel or guest-house package.
Why the single vanity is a coordination item, not a standalone purchase
A Single Vanity carries the basin, sets the working height, decides where the waste and supply lines have to land, and often determines the storage plan for the room. When quantities are planned without this in mind, the same problems appear repeatedly: units ordered in sizes that do not fit the finished wall, storage that cannot hold what the household actually keeps, and deliveries that force trades on site to stop work while replacements are arranged.
Planning is simpler when the vanity is treated as the anchor of the washbasin zone. Every decision around it—countertop material, mirror type, lighting position, the location of the rest of the sanitaryware—can then be checked against one fixed reference point.
Step 1: Count the rooms, then count the stations
Start with a room-by-room list rather than a single total. For each bathroom, powder room, ensuite and laundry area, record the room dimensions and who uses the space, then decide how many wash stations that room needs:
- One station per room is standard for ensuites, guest bathrooms and powder rooms.
- Two single vanities at separate stations work well in a main bathroom shared by two people, and often suit a shared guest bathroom better than one wide unit.
- A Double Vanity suits a main bathroom where two people should be able to use the room at once. The double and single lines can share size range, materials and finishes, so the rest of the home keeps a consistent look even where layouts differ.
The quantity for each model follows directly from that room list. Write it as "room / station count / vanity type / unit size", because the same sheet will carry the mirror, lighting and countertop orders later, and any change made after tiling begins costs far more than a change made on paper.
Step 2: Fix dimensions before anything else
Do not order to a nominal vanity width. Measure the finished wall, including tiles, plasterboard and any niche or pipework shaft, and check door swings and drawer clearance before the size is locked. Santerson vanities are made-to-measure products: the Single Vanity can be specified with project-specific dimensions, material and finish options, and a layout tailored to the space, rather than chosen from fixed catalogue sizes.
With custom sizing, one vanity range can serve the whole schedule—ensuite, guest bathroom and powder room—so quantity is set by function rather than by what happens to be in stock. Confirm the final dimensions and specification for every unit at the time of ordering, since each size is project-specific.
Step 3: Match the vanity type to the room
Choose the type first, then set the quantity for each type:
- Floating Vanity — wall-hung, keeps the floor visible, and makes cleaning and tiling simpler; wall framing, any concealed cistern and the waste position must be planned together with it.
- A floor-standing single vanity — the conventional choice where floor support is preferred or wall fixing is difficult.
- Integrated Countertop Vanity — counter and basin formed as one piece, fewer joints to maintain, but countertop, basin and storage configuration need confirming per project.
A practical rule: keep to one or two vanity types across the project and let size and finish provide the variation. More types mean more drawings, more samples and more chances of a wrong unit arriving on site.
Step 4: Coordinate the products around the vanity
Countertop and basin
Decide the basin style early, because it fixes the cut-out, the tap hole positions and the waste depth. With an Undermount Basin, the cut-out must match the basin and the countertop has to be thick enough for the fixing hardware. A Vessel Basin (Above Counter) raises the usable deck height, so vanity height, tap reach and mirror position all need checking again. Where stone or engineered surfaces are specified, Stone & Marble Surfaces can be made to measure so the counter, splashback and adjacent benching sit on one material schedule.
Mirror and storage
Mirror and vanity share one wall and one sight line. An LED Mirror Cabinet stores the items that would otherwise be kept in a cupboard, but it needs a power point set behind or beside it, and that point has to be on the first-fix drawings. If mirror storage is not needed, a plain mirror keeps the electrical work lighter. Order the vanity and the mirror in the same round so finishes and frames match.
Lighting
Vanity Lighting is likewise specified per project for size and finish, so its quantity and position belong on the same schedule as the vanities rather than being added at the end. Plan it against the mirror or mirror cabinet together, and record the cable point for each fitting before the wall is closed up.
The rest of the wet room
Once the vanity wall is set, the other items follow on the same levels: the Modern Rainfall Shower System with Handheld Sprayer needs its valve and riser positions marked, and wall-hung sanitaryware needs its fixing heights confirmed from the same elevation drawings. Listing these against the vanity zones keeps the whole bathroom on one set of dimensions.
Step 5: Build one coordination sheet that everyone uses
One sheet, shared by the designer, the plumber, the tiler and the supplier, prevents most clashes. For every vanity location, record:
- Room name and unit number, quantity, and which vanity type applies.
- Finished width, height and depth, plus supply and waste positions on the elevation.
- Countertop and basin choice, with cut-out and tap-hole details.
- Mirror or mirror cabinet size, plus the position of its power point.
- Vanity lighting quantity, fitting size and fixing position.
- Finish and handle selection, so every bathroom draws from one finish schedule.
Step 6: Order, deliver and store in site sequence
Group orders by construction stage, not by product category. Vanity units, countertops and mirror cabinets reach site at different points in the job, and anything needing an electrical or plumbing point has to arrive before the wall is closed. With made-to-measure work, allow production time in the programme before tiling is fixed, and check the drawings once more at order confirmation. On delivery, check each crate against the room list, store vanities flat and dry, keep basins and stone tops protected until the final stage, and expect the supplier to confirm dimensions and selected specifications for each configuration before packing.
A worked example: one storey of four bathrooms
Take a floor with a main bathroom, two ensuites and a powder room. On paper that reads as four vanities. In reality: each ensuite takes one single vanity; the main bathroom is planned with two single vanities at separate stations; the powder room takes one narrower single vanity. Four single vanities, each with its own size, basin choice, mirror and light, and each with its own plumbing and electrical points on the elevation. Quantity plus the room sheet—not quantity alone—is what the supplier and the trades need.
Five checks before the order goes in
- Does every unit quantity trace back to a named room and station on the schedule?
- Are dimensions taken from finished wall lines and confirmed with the supplier in writing?
- Do the countertop, basin, mirror and lighting details sit against each vanity, not on a separate list?
- Have plumbing and electrical points been set from those same drawings?
- Does the delivery plan follow the order in which the trades will work?
If any answer is no, correct it on the sheet before ordering. On paper the fix costs an hour of design time; on site it costs a trade, a tile run and a week of programme.
How one supplier takes the coordination off your plate
SANTERSON is a one-stop furniture and building materials supplier based in China, producing vanities, basins, countertops, mirror cabinets, lighting and other bathroom and interior products for villa, hotel and apartment projects, with custom/OEM production and door-to-door delivery. Because vanities, mirror cabinets and vanity lighting are specified per project, a single order can cover the whole washbasin zone: matching sizes, matching finishes, and one coordination sheet instead of several.
Before quantities are finalised, send the room-by-room schedule and the elevations. Specifications can then be checked against the drawings, and units are made to the sizes and finishes the project actually needs.
