A corner unit in a bathroom rarely gets the attention it deserves. The angle is awkward, the depth changes halfway down, and what fits on paper often clashes with the door swing, the basin or the pipe chase behind the wall. That is exactly why Santerson Corner Storage is listed as a configurable product rather than a fixed catalogue item: dimensions, layout, material and finish are set to the space, not the other way round. The practical consequence for a buyer is simple. The quality of the answer you receive depends almost entirely on the quality of the information you send first. The checklist below is what we ask project owners, contractors and interior designers to have ready, so the first reply already moves the job forward instead of opening another round of questions.

Start with the wall you are working into

Before anyone talks about styles, the corner itself needs to be described. Two measurements decide most of the design: the length of each wall from the corner to the nearest obstruction, and the clear depth available once wall finishes are accounted for. A finished tile face sits proud of the structural wall, and a unit specified against the bare wall can arrive proud of the basin or short of the toilet cistern. Note the height of any window sill, mirror, towel rail or existing light switch, and say where the door of the unit should open from — left to right, right to left, or hinged so it does not fight the bathroom door. If the corner is not square, say so plainly. Older villas and renovated apartments rarely hold a true 90°, and a made-to-measure unit is only useful if the actual angle travels with the order.

Photographs settle most of this faster than words. A shot straight into the corner, one from each side wall, and one showing what the unit will sit next to — vanity, shower screen, WC — gives the design team a picture they can check the numbers against. A rough sketch on the printed floor plan, with the measurements written on it, is enough. The goal is that whoever reads your enquiry does not have to guess what you meant.

Write down what actually has to fit inside

"Storage" covers several different jobs, and they need different internals. Towels and bath linens want open or shallow shelving. Cleaning bottles, hair tools and spare rolls work better in drawers or closed cabinets where the contents stay out of sight. Toiletries used every morning should sit within reach of the basin, while bulk stock can go higher or lower. Tell us the tall items you own or intend to store — a floor-standing bottle, a basket, a hair dryer — because shelf heights and drawer depths follow from that list, not from a standard module. If the same bathroom serves several bedrooms in a villa or a set of guest rooms in a small hotel, say how many people it needs to serve at the same hour. That changes whether a single narrow corner unit is enough or whether a matching drawer unit next to it makes the room work.

Bathrooms are humid, and the finish needs to be chosen for that reality. State whether the corner sits inside a wet zone or outside it, whether the room has mechanical extraction or only a window, and whether the wall behind is tiled, plasterboard or an existing finished surface. These details decide the board and surface specified, the edging, and how the unit is fixed. A finish copied from a bedroom wardrobe may look right in a rendering and fail on a wall that gets splashed daily.

Match the finish to the rest of the room

Corner storage in a residential bathroom rarely stands alone; it is read against the vanity, the mirror cabinet, the doors and often the wardrobes in the adjoining bedroom. Send a reference for what it has to sit beside: the vanity colour and surface, the tapware finish, the wall tile, and the floor. A photograph of the room as it stands now, or the specification sheet if the project already has one, prevents the awkward moment when a delivered unit clashes with a vanity that was ordered separately. Where the whole bathroom is being specified together, it is worth looking at the bathroom sanitary fixtures range at the same time, so the ceramics, mirror cabinets, vanities and storage units are specified against one set of dimensions and one finish schedule.

Names of colours are unreliable between suppliers. Instead of writing "grey" or "oak", attach a sample reference, a RAL or brand code if you have one, or a photograph of a physical sample held in your hand. If you have no reference yet, say which direction you want — pale and light-reflecting, warm wood tones, or a dark finish against light walls — and let the sample stage settle it.

Say who is on site and what the delivery route looks like

Made-to-measure units are built once, so the last thing to get wrong is the journey from the factory floor to the bathroom door. Tell us the delivery address, the floor, and whether a lift, stairwell or narrow hallway is involved. A unit that fits the bathroom may not fit around a turn in the corridor, and that question needs answering before crating, not after. Give the name and phone number of whoever receives goods on site, and the date by which the unit must be installed if the bathroom is holding up another trade. If you are buying for several bathrooms or several units in one project, mention that up front: units for the same project travel better together, and the same finish schedule applies across all of them.

If you want the unit installed rather than simply delivered, say so in the first message, along with who is doing the other work in the room. Site conditions for fixing to different wall builds, and the order in which tiling, vanities and storage are fitted, are coordination questions and are far cheaper to settle before production starts.

Bring a budget band, not a silence

An approximate budget band helps us specify sensibly on the first pass. Custom corner units vary with internals, drawer count, door type and surface, so an honest range lets the specification be built to it instead of being quoted at the top and then cut back. If the cost is a fixed line in a project budget, say what is fixed and what has room to move. This is how a quotation ends up close to the number you can sign, rather than a proposal you have to send back for revision twice.

Where the corner unit is one part of a larger fit-out

Often a corner storage enquiry begins as a single bathroom and turns into a whole-floor or whole-villa specification: wardrobes in the bedrooms, vanities and mirror cabinets in the bathrooms, kitchen cabinetry, doors and wall panelling in the same finish schedule. In those cases it is worth sending the room list and drawings at the start. Grouping the joinery in one specification keeps finishes consistent, keeps dimensions checked against the same drawings, and keeps delivery and installation on one programme. Our turnkey project services cover exactly that kind of coordination, from space planning and material selection through production, delivery and site support.

A quick pre-enquiry checklist

• Both wall lengths from the corner, plus the clear depth after wall finishes, plus the actual corner angle if it is not square.
• Fixed items near the corner: basin, vanity, WC, shower screen, window sill, mirror, switches, and where the unit door must open.
• The contents list that drives shelves, drawers and closed cabinets, and the tall items that set internal heights.
• Room conditions: wet or dry position, ventilation, wall build, and whether the wall is tiled or plastered.
• Finish references in codes or photographs, not colour names, plus what the unit has to match.
• Delivery address, access route, on-site contact, required install date, number of units, and a budget band.

Send those details with the enquiry and the first response can already carry a workable configuration and a price that means something. Missing half of them costs a round of emails; missing the dimensions and the finish references costs a wrong unit. For a homeowner with one bathroom, a phone call with a floor plan is enough to start. For a project with several bathrooms, drawings and a room list will do the same job in one pass either way — and the corner is no longer an awkward leftover, but a piece of joinery that was planned in from the beginning.
