One Piece Toilet

One-piece toilets integrate the tank and bowl into a single seamless ceramic unit, giving a low-profile, skirted form that is easy to clean and quick to install. This range is offered with dual-flush and single-flush systems for water-efficient residential, hotel and apartment bathrooms, and sits alongside the separate-cistern two-piece and electronic smart toilet ranges inside the full toilet catalogue. Custom branding, flush configuration and packaging available for OEM/ODM and private-label programs.

    Drain first, shape second

    Which drain does each one piece toilet fit?

    A one piece toilet joins tank and bowl in a single ceramic body, so the outlet settings each model lists are the first filter. Sort the 40 models shown here by rough-in before comparing styles. All 40 are floor-mounted, white ceramic and list an S-trap outlet.

    The four 12-inch HSJ bodies list no P-trap option. NBK-3076 is the only one of the 40 that lists both a 300 mm S-trap position and a 180 mm P-trap outlet.

    Lengths across these 40 one piece toilets run from 590 mm (HSJ-2531) to 760 mm (HSJ-2555); heights run from 700 mm (TC-58138H) to 810 mm (NBK-3077, NBK-3074 and NBK-3073). A dash in the Flush column means flush type is confirmed in the quotation.

    Widths stay in a narrow band, 350 to 410 mm, so length and height are the dimensions that separate one model from the next.

    One body or two

    One piece vs two piece toilets for a trade buyer

    A two piece toilet pairs a separate tank with the bowl. A one piece toilet joins tank and bowl in a single seamless ceramic unit, so there is no tank-to-bowl joint to assemble during installation and no gasket at that joint to add to a maintenance list. With no gap between tank and bowl, there is also no crevice at that point where dirt and grime can accumulate. This range is offered for residential, hotel and apartment bathroom projects, with dual-flush and single-flush systems.

    The trade-off is handling: each one piece unit is a single large ceramic body, so carton size and pallet counts should be checked against the drawing early. If a program needs both constructions, list one piece and two piece models in one inquiry and compare them on the rough-in each lists. A distributor adding a new toilet line can then hold both types under one bathroom assortment.

    Writing the inquiry

    Five details for a complete one piece toilet quote

    1. Model and rough-in

      Name each model and the S-trap or P-trap setting you need, e.g. HSJ-2550 at 150 mm. Where a body lists two positions, say which one goes on the carton.

    2. Flush type and volume

      State whether your market expects dual flush or single flush, and the volume your code allows. On a dual flush system the reduced volume is meant for liquids and the full volume for solid waste. The 14 NBK bodies have flush type set in the quotation, and flush configuration can be customized for OEM programs.

    3. Bowl outline

      Ask for the bowl outline on each model's drawing so it can be checked against the project specification before the order is fixed.

    4. Quantity per model

      MOQ is set per model and the price is quoted per order, so list quantities by model rather than as one total.

    5. Branding and destination

      Tell us the port, any logo or carton artwork for private label, and documents you need. OEM details are on our OEM/ODM service page; written replies arrive within 12 business hours.

    Wholesale One-Piece Toilets, Factory-Direct

    SANIKB manufactures one-piece toilets in glazed ceramic, white throughout with one black model, supplied factory-direct for importers, distributors and project buyers. The range spans siphonic, washdown and swirl flush models with S-trap and P-trap outlets, MOQ is quoted per model, and OEM/ODM and private-label programs are available.

    Skirted Elongated Modern Design

    Many models have a skirted body that conceals the trapway behind a smooth side wall, so there are no contours to trap dust and the unit wipes clean in seconds. The elongated bowl reads as a premium silhouette that photographs well online and merchandises cleanly on showroom floors, while the seamless one-body design removes the tank-to-bowl gasket and a common leak point.

    Flush System, GPF and Rough-In

    The siphonic 12 in (305 mm) models run 1.28 GPF (4.8 L) full and about 0.8 GPF reduced on dual-flush units, with top-button and top-or-side-button options. Washdown, siphonic and swirl models add 250 mm (10 in) and 400 mm S-trap settings and a 180 mm P-trap outlet; OEM flush volumes can be configured to your market water-consumption rules.

    OEM, ODM and Private Label

    SANIKB supports private-label programs across the one-piece range: your logo, cartons and documentation applied at the factory, plus tailored variants. As a factory-direct manufacturer you deal with the maker rather than a trading layer, with direct pricing and consistent batch quality across repeat orders.

    Quality, cUPC Compliance and Export Packaging

    Every one-piece toilet is high-fired vitreous china, with cUPC-marked models for North American projects with certificate scope confirmed per model and market. In-house QC covers firing, glaze coverage, water-tightness and dimensional checks before packing, and units are crated in foam-cushioned export packaging engineered for ceramic ocean freight.

    FAQs

    What does this one piece toilet collection include?

    This collection holds floor-mounted one piece toilets in glazed ceramic, white throughout with one black model. Siphonic models on a 12-inch (305 mm) S-trap rough-in sit alongside washdown, siphonic and swirl flush models that list 250, 300 or 400 mm S-trap rough-ins and a 180 mm P-trap outlet, so the Flushing, Outlet and Rough-In filters narrow the list quickly. As a one piece toilet manufacturer we keep the line export-ready, so importers and private-label brands can build a cohesive bathroom assortment. To compare two-tank construction, browse our

    two-piece toilets.

    What is the difference between a dual flush and a single flush one piece toilet here?

    A dual flush one piece toilet gives end users two volumes from one valve, a lighter flush for liquid waste and a fuller flush for solids, which appeals to water-conscious markets and spec sheets. A single flush one piece toilet uses one consistent volume, simpler to service with fewer valve parts. Flush volume differs by model, so check the Flush System filter and each model's spec sheet. Tell us your target market and we will recommend the right mix per order.

    What makes a skirted elongated one piece toilet a good fit for resale?

    A skirted one piece toilet hides the trapway behind a smooth concealed side, so there are no contours to trap dust and the unit wipes clean in seconds, a selling point your retail and trade buyers value. The elongated one piece toilet bowl reads as a premium, modern silhouette that photographs well online and merchandises cleanly on showroom floors. The seamless one-body design also removes the tank-to-bowl gasket, cutting a common leak point and reducing warranty claims across a deployed fleet.

    Are these one piece toilets cUPC-ready and certifiable for North America?

    Yes — the line is cUPC-ready, the specification North American importers and big-box compliance teams ask for during onboarding. Exact certificate scope is set per model and market, so we confirm in writing which listings apply to your chosen SKUs before you commit, and supply the supporting documentation your customs and plumbing-code review need. Tell us your destination market and target models and we will align the paperwork to that requirement rather than promising a blanket certificate.

    How do you control glaze and quality on every one piece toilet?

    Each one piece toilet is high-fired vitreous china with a fully glazed surface for stain resistance and reliable flush performance. As a factory-direct one piece toilet supplier we run in-line QC across the body: kiln firing, glaze coverage, water-tightness, flush-and-drain function, and dimensional checks before packing. We can also share AQL sampling terms and pre-shipment inspection reports, and welcome third-party inspectors so your team verifies build quality before goods leave the plant.

    Do you offer OEM, ODM, and private-label one piece toilets, and how is export packaging handled?

    Yes. As a one piece toilet OEM and ODM manufacturer we support private-label programs: your logo on the product and seat, custom cartons and inserts, branded fittings, and tailored model variants. Export packaging uses foam-cushioned cartons and reinforced corners engineered for ocean freight, with palletization and container-load plans to protect ceramic in transit. We confirm carton dimensions, gross/net weights, and loading quantities up front so your logistics and customs paperwork are accurate.

    What are the standard flush, GPF, and rough-in specs across this one piece toilet range?

    The siphonic models on a 12-inch (305 mm) rough-in run 1.28 GPF (4.8 L) for the full flush and about 0.8 GPF for the reduced flush on dual flush versions. Other models list washdown, siphonic or swirl flushing with 250, 300 or 400 mm S-trap rough-ins and a 180 mm P-trap outlet, and their flush volume is confirmed per model. For OEM programs the flush volume can be configured to your market water-consumption rules, and we confirm the exact GPF and rough-in on the spec drawing for each SKU before production.

    What is the MOQ, lead time, and how do I get a wholesale quote?

    MOQ is 30 pieces per model on the established siphonic models and is quoted per model for the others, suited to importers, distributors, and commercial one piece toilets projects testing a new assortment. Lead time depends on order size, customization, and certification scope, and we confirm a firm production schedule with each quote rather than a generic figure. Share your target SKUs, quantities, destination, and any branding needs and our engineers return a costed wholesale quote. If your project also needs

    smart toilets or the broader toilet range, we can quote them together.
