Guest bathrooms decide how a hotel feels long after the lobby furniture has been photographed. When a hospitality project reaches the sanitary-ware schedule, the specification has to survive hundreds of uses a week, a housekeeping routine that runs on a timer, and a plumbing riser that was drawn before anyone chose a water closet. The Washdown One Piece Toilet, Modern Ceramic 1003A Toilet for Bathroom (2260) sits in that decision: a one-piece vitreous ceramic water closet with a washdown flush and a choice of wall or floor drainage. This article walks through how purchasing teams, contractors and project managers can specify and order it properly for a hospitality project, and which coordination items need to be closed out before a purchase order is released.

Why hospitality buyers shortlist a one-piece washdown WC

Compared with a close-coupled two-piece WC, a one-piece toilet is cast as a single body, so there is no seam between the tank and the pan where dirt and moisture collect. The 1003A product description makes the same point about its seamless design, and the practical consequence shows up in the housekeeping rota: fewer crevices to scrub, less time per cubicle, and no joint between cistern and bowl to age and discolour. For a floor of identical guest bathrooms, minutes saved per clean compound across the whole property.

The 1003A is a washdown design. In hospitality specification terms that matters because the guest does not need to understand the hydraulics; they need one flush to clear the bowl. Washdown pans hold a water seal in the trap that blocks odour from the drain, and the flush washes the surface rather than siphoning the whole bowl empty. Housekeeping teams and front-of-house staff judge a bathroom by what they see on the first visit, so a pan that rinses clean and keeps its water level looks maintained even late in a busy turnaround.

Material is the third reason this type of WC gets specified. The 1003A is described as high-quality vitreous ceramic with a glossy glaze, resistant to staining and yellowing. In a hotel that means the pan keeps up with daily cleaning chemicals and does not dull within the first year of operation. When you are evaluating any supplier's ceramic, ask who fires the body, how the glaze is applied, and how the finished units are inspected before packing, and keep the answers on file with the submittal.

Reading the 1003A product record before you specify it

The catalogue entry for this model is recorded twice on the site, at https://www.santerson.com/2260.html and at https://www.santerson.com/washdown-one-piece-ceramic-toilet-1003a.html. Use whichever URL your document control system resolves, but state the model number, 1003A, in every drawing, schedule and purchase order so the numeric page and the descriptive slug cannot drift apart in correspondence.

Two technical lines in the product record do most of the work in a hospitality specification. First, the outlet: the 1003A supports a P-trap wall drain at a 180 mm rough-in and an S-trap floor drain at a 250 mm rough-in. Second, the flushing type: washdown, with the product copy claiming reliable performance and efficient water consumption. The first line is a hard coordination item that decides the stack layout; the second is a performance claim that should be tied to supplier documentation before it goes into a tender.

Match the trap way to the stack, not the other way round

The most expensive mistake in WC procurement is choosing the pan before the drainage route is fixed. A wall-hung stack wants a P-trap outlet, which turns the discharge horizontally into the wall and down the shaft; the 1003A P-trap option is recorded with a 180 mm rough-in. A soil pipe in the slab wants an S-trap outlet, which drops from the back of the pan and loops down into the floor; the recorded rough-in is 250 mm. Rough-in is measured from the finished wall face to the centre of the waste outlet, so state clearly in the schedule whether the figure assumes finished or structural face. That single line prevents most on-site rejections.

In a guest-room tower, most bathrooms are stacked in pairs back to back, and the trap way follows the shaft. Pick one outlet type per stack and keep it constant across the floors: mixing P-trap and S-trap pans in the same riser complicates the branch fittings, changes the depth of the boxing, and creates two different sets of spare parts for the maintenance team. Where a suite layout genuinely needs a floor outlet and an adjoining bathroom needs a wall outlet, show both on the reflected ceiling plan and number the pans to match, so the same 1003A body covers the project while the outlet code changes room by room.

The seat is a separate line item, and hospitality projects should treat it that way. Hinge centres, seat shape, quick-release for cleaning and the closing mechanism all affect the room's feel, and seats travel separately from ceramics, so order them in the same contract with the same quantity control, including spares for the stores.

Build the specification package the way a project actually buys it

A hospitality procurement package for this WC is not a product screenshot and a quantity. It is a small document set, and each part answers a different question asked by a different party at a different stage.

Santerson's own cooperation steps follow the same order the project does: a design proposal against your brief, then quotation and detail confirmation, then production, shipment and follow-up. Treat the middle step as the control point. Detail confirmation is where the outlet type, rough-in figure, seat selection and quantity per room type are written down and signed. Get it wrong there and the correction is paid for at the site.

Quantities, breakages and the delivery reality

Ceramics travel as freight, and hospitality schedules are built room by room, so quantity control needs two passes. First count from the room types: for a guest floor, one pan per bathroom, plus the number in the public and staff restrooms, plus the units for the spa, gym or food and beverage areas. Then add a contingency for transit damage and for the operator's stores. Order in whole crate quantities rather than a single odd unit, because suppliers pack in standard pallet configurations, and a rounding difference discovered after production has started becomes a change order.

Inspection on arrival is a scheduled activity, not a formality. Open a sample of crates from each pallet, check the glaze for hairline crazing and the rim for chips, and confirm every carton contains the same model code and outlet type. Photograph any damage the same day, with the crate marking and the packing list in frame. That evidence supports the insurance claim and the replacement shipment; without it, the replacement comes out of the project contingency.

For international shipments, agree the paperwork before production starts. The supplier's logistics service covers freight forwarding by sea, air and rail, customs documentation, packaging and container loading, shipment tracking and door-to-door delivery, and its page mentions commercial invoices, packing lists, certificates of origin and import permits. Your import agent should confirm which of those documents the destination customs authority requires for sanitary ceramics, and what duty and clearance route applies to your consignment, so nothing is invented in the project programme and nothing is discovered late at the port.

Mock-up rooms are where the specification stops being a guess

Order one or two sample 1003A units and install them in a mock-up bathroom with the chosen seat, the boxing, the flush arrangement and the actual cleaning chemicals the housekeeping team will use. Leave the mock-up in service for at least a week of real use. The room tells you things the submittal cannot: whether the pan rinses in one flush, whether the rim stays clean, whether the seat sits level on the finished floor, how much noise the flush carries into the adjacent bedroom wall, and whether the housekeeping team can clean around the base without a workaround.

Record the mock-up findings as a signed document and freeze the model after sign-off. Any later substitution, such as a different outlet, a different seat or a different supplier, reopens the room type and the plumbing coordination for every floor that uses it.

Coordinate the rest of the wet schedule around the WC

A guest bathroom is bought as a set, and the WC is only one item in the schedule. Where the design calls for a matching suite, Santerson's Sanitary Fixtures / Bathrooms range carries the other pieces of the wet schedule: the wall-hung Wall Hung Ceramic Basin 1003B recorded under the same 1003 series, freestanding pedestal basins, bidets and the rest of the category. Specifying the WC, basin and fittings from one catalogue range reduces the number of submittals, keeps glaze colour and profile consistent between items, and lets one supplier carry the ceramics schedule.

The wet schedule also has to be read against the hard finishes. The wall tiling setting-out determines where the outlet lands and therefore which rough-in is achievable; the vanity position determines whether the pan can sit centred with a clear approach; and the mirror cabinet, lighting and shower set all sit on the same wall faces that the plumbing penetrations cross. Put the bathroom elevations and the sanitary schedule on the same drawing sheet for the coordination meeting, and mark the WC outlet on both. That is where a project catches a clash while it is still a line on a screen.

A pre-order checklist for the 1003A

• Confirm the model code (1003A) and one product reference URL in the schedule and the purchase order, so the numeric and slug versions of the page cannot be confused.
• Fix the outlet type per stack, P-trap or S-trap, and state the rough-in with the finished-face assumption written out.
• Get the current supplier submittal with a dimensioned drawing, glaze and body details, and the flush and certification data for the destination market; the site page's certification note is not a substitute for the certificate.
• Specify the seat as a separate line item with hinge centres, finish and spares for stores.
• Sign off an installed mock-up before the bulk order, with housekeeping present.
• Confirm crate and pallet configuration, total crate count and site storage, and write the arrival inspection into the programme.
• Confirm with your import agent which documents are needed for customs and which route applies; do not rely on marketing copy for duty, transit time or delivery scope.
• Agree in writing what after-sales cover applies to ceramics and what spares the operator holds.

Bringing it to a decision

For a hospitality project, the 1003A is a sensible candidate wherever the design wants a seamless one-piece pan, a washdown flush, and the flexibility to answer either a wall outlet at 180 mm or a floor outlet at 250 mm rough-in. The commercial risk is not in the ceramic body. It is in the coordination around it: the trap way per stack, the rough-in convention, the seat, the mock-up sign-off, the crate plan and the customs documents. Close those items in the detail-confirmation stage and the bulk order becomes routine. Leave them open and the project pays for them at the site, on the day the tiler has already fixed the wall.

Send your bathroom schedule, room counts by type and stack layout to the SANTERSON project team for a quotation with the outlet and rough-in figures confirmed in writing, and ask them to return the submittal drawing for the mock-up. That single exchange turns the 1003A from a catalogue page into a specified, deliverable line item on your hospitality project.
