One-Piece Washdown Toilet Body, Flush & UF Cover

One-Piece Ceramic Toilet Body

WP-5004 is a floor-mounted ceramic toilet with a one-piece body. The bowl and cistern body are combined, so the order does not involve matching a separate close-coupled tank to the pan. The cistern cover, seat and internal fittings remain service parts. That distinction matters when comparing the complete fixture with a bare pan or a wall-hung bowl that needs a separate concealed cistern.

Washdown Toilet Flush & Control Settings

The specified flush type is washdown. The model description identifies a control with two flush selections; the operating volume depends on the fitted mechanism and its setting. The proposed assembly carries its full and reduced volume information and any documentation required for the destination. The control format alone is not an efficiency certification.

UF Toilet Cover, Hinge Fit & Replacement Parts

We confirm A UF cover with the ceramic toilet. For a project order, the seat profile and hinge fit should remain tied to WP-5004 so replacement parts fit the same bowl. Cover removal provides access for cleaning, but the release method follows the supplied hinge.

WP-5004 S-Trap & P-Trap Toilet Configurations

S-trap 250 mm and 300 mm choices for floor-outlet layouts and P-trap 180 mm choice for a wall-outlet layout

S-Trap 250 mm Toilet Configuration

The 250 mm S-trap is one of the listed WP-5004 connections. An S-trap arrangement serves a floor outlet, so the choice starts with the building waste position and the proposed pan connection. The 250 mm label stays attached to this version in the quotation. The matching installation drawing supplies the measurement points and connector arrangement for the room.

S-Trap 300 mm Toilet Configuration

The 300 mm S-trap is a separate listed selection for a floor-outlet layout. It should not be substituted for the 250 mm version simply because the ceramic body looks similar. The two S-trap entries remain separate in the room schedule, so each bathroom receives the version intended for its waste position.

P-Trap 180 mm Toilet Configuration

The 180 mm P-trap selection uses a wall-outlet arrangement. It is intended for a different waste route from the two S-trap selections. The wall connection, coupling and installation access need to suit that version. Selecting P-trap in the inquiry carries the 180 mm model label into the request without treating the floor and wall connections as interchangeable.

Toilet Waste Connection, Water Supply & Bathroom Fit

Toilet Trap Selection & Existing Waste Position

Start the fixture schedule from the waste route: floor for an S-trap layout, wall for a P-trap layout. The listed 250, 300 and 180 mm values identify the WP-5004 version, and its drawing must use the same measurement points as the site survey. An offset connector is an extra component, used only where the drawing shows it fits.

Toilet Water Inlet, Isolation Valve & Cistern Access

The cistern needs a water supply matched to its inlet fitting, with inlet position, connection thread and access to the isolation valve planned along with the waste trap. Leave space to lift the cistern cover and service its fittings. Supply hoses, valves and any pipe relocation are installation items.

Toilet Overall Size, Seat Height & Door Clearance

WP-5004 has a listed overall size of 730 × 335 × 720 mm. The bathroom layout still needs the bowl and seat dimensions, movement space beside and in front of the fixture, and a clear door swing. For an accessible or height-specific bathroom brief, the actual fixture dimensions and applicable project requirements must be matched before selection.

One-Piece Toilet Pricing & Supply

One-Piece Toilet Trap Version & Quantity

The product subtotal identifies WP-5004, the selected S-trap 250 mm, S-trap 300 mm or P-trap 180 mm version, the finish and quantity. A multiroom order can group units by connection type and delivery stage. Keeping those groups explicit prevents a single toilet quantity from hiding several different installation requirements.

UF Cover, Flush Valve & Inlet Fittings

The component list names the matched seat and UF cover, hinge arrangement, flush mechanism and inlet fittings, with spare seats, hinges or valves as extra lines. That keeps the ceramic fixture and its service parts together as one defined package, with replacement quantities planned for the project.

Toilet Connector, Fixing & Plumbing Work

The selected waste connector, seals and fixing hardware need their own supply entries. Site preparation, water-feed alterations, drain changes and installation labor are separate tasks. For replacement projects, removal of the old fixture and disposal can be priced alongside installation.

Ceramic Toilet Packing, Freight & Room Delivery

The ceramic body, cistern cover and seat need protection against movement and contact during transport. Packing and shipment quantities are listed for the actual order, with any spare units separated from installation quantities. Freight uses the packed dimensions and destination; unloading, stairs or lifting and delivery to individual bathrooms are distinct charges when required. Tell us the rooms and quantities and we will put this on one quote with everything else you are ordering, and show you what fits in a container.

One-Piece Washdown Toilet FAQs

Which trap configurations are listed for the WP-5004 toilet?

The listed choices are S-trap 250 mm, S-trap 300 mm and P-trap 180 mm. S-trap is for a floor-outlet arrangement; P-trap is for a wall-outlet arrangement. The selected version needs a matching installation drawing and connector, with the measurement points checked against the room.

Is the 300 mm S-trap toilet the same as a 12-inch rough-in toilet?

No. Twelve inches is 304.8 mm, while this model lists 300 mm. Compatibility depends on the actual pan drawing, connector and installation tolerances. The order should retain the WP-5004 connection label and be matched to the measured site layout.

What seat and cover are specified for the one-piece toilet?

We confirm A UF cover with the WP-5004 ceramic fixture. The quotation should name the matched seat, cover and hinge set so the supplied components and future replacements remain clear. Soft-close action or a particular quick-release mechanism is a separate feature.

How much water does the WP-5004 use per flush?

The WP-5004 is a washdown toilet with a dual full and reduced flush. We confirm both flush volumes for the flush assembly fitted to your order, so you can check them against your local water-efficiency rules before you approve the sample.

Does the listed toilet size tell me the seat height and installation clearance?

No. The listed overall size is 730 × 335 × 720 mm. Seat height, bowl dimensions, fixing points and the space needed around the toilet are separate. The bathroom plan needs the actual fixture drawing, door swing and required user clearances, especially where a specific accessible layout is part of the brief.

What should a project toilet quotation include besides the ceramic body?

It should identify the selected trap version, matched seat and cover, flush and inlet fittings, and any supplied connector, seals or fixing hardware. Spares, packing and freight are separate entries. Local plumbing changes, installation, removal of old fixtures and final-room delivery are included only where they are expressly listed.
