One Piece. Six Flush Technologies. Every Drainage Standard. One Global Line.

 

A one piece toilet should fit the bathroom, not the other way around. Yet most one piece lines force the buyer into a single flush type, a single drainage pattern, and a narrow rough-in range. YingJie's non-CUPC one piece line is built on the opposite principle: 60+ models across six flush technologies — Tornado, Siphonic, Washdown, Double Hole Eddy, One Hole Eddy, and Four Hole Eddy — with S-trap rough-in from 150mm to 400mm and P-trap wall outlet at 180mm. Whatever your local plumbing standard demands, there is a YingJie one piece model that fits it without compromise.

Certified for global markets with CE, Watermark, SASO, WELS, and ISO9001, this line serves projects across Europe, Australia, the Middle East, Southeast Asia, Africa, and South America — each model sharing the same seamless vitreous china body, 1,280°C firing, and sub-0.2% water absorption that defines a one piece toilet built to last. 30,000 units per month capacity. 600+ containers shipped annually. Since 2010. One global line, one factory, every option you need.

Why Choose YingJie for One Piece Toilet Sourcing

60+ Models — The Broadest Range in One Catalog

From the compact YJ-7019 (590mm depth, perfect for en-suites) to the statement YJ-7015 (720mm with four-hole eddy flush), our one piece line covers every depth, width, and height requirement. Six flush technologies. Dual drainage standards. 60+ models in one catalog means you specify once and source once — no need to qualify multiple factories for different bathroom sizes.

S-Trap & P-Trap — Every Drainage Standard Covered

S-trap rough-in from 150mm to 400mm. P-trap wall outlet at 180mm. Washdown and double-hole models available in both configurations. Whether your project is in Europe (P-trap standard), Australia (S-trap 200-300mm), the Middle East, or Southeast Asia, the right drainage pattern is a model selection — not a custom order.

Seamless One-Piece — No Joint, No Leak, No Crevice

Tank and bowl are a single vitreous china casting. There is no gasket, no bolt, and no joint between them — eliminating the most common leak point in two-piece toilets and the crevice where moisture and bacteria accumulate. The smooth, continuous surface from tank lid to bowl base also means faster, more effective cleaning.

CE, Watermark & SASO — Pre-Certified for Global Markets

European CE conformity. Australian Watermark. Saudi SASO. WELS water-efficiency rating. ISO9001 quality management. Every model ships with the certification documentation required for its target market — pre-audited and maintained through annual renewal. No post-purchase lab testing delaying your project timeline.

Manufacturing Scale — 600+ Containers Per Year

60,000㎡ production facility. 200 skilled workers. 30,000 units per month across all toilet categories. 600+ containers shipped annually to 50+ countries. This is not a trading company aggregating orders — this is a factory manufacturing at scale, with the production capacity to absorb your project volume without lead-time extensions.

Configurable to Your Specification

PP or UF soft-close seat. Standard or WDI premium water parts. Water-transfer ceramic decoration. Custom color matching via Pantone. Custom logo and branded packaging. Side-flush lever or top dual-button. Rough-in configured to your market. One piece toilet procurement where every variable is a checkbox, not a compromise.

 

What Is a One Piece Toilet?

A one piece toilet — also known as a single-piece toilet, close-coupled integral toilet, or one piece toilet — is a toilet in which the tank and bowl are formed as a single continuous vitreous china body. Unlike a two-piece toilet where the tank is a separate casting bolted onto the bowl with a rubber gasket, the one piece has no mechanical joint between the tank and the bowl. They are one ceramic piece, from the tank lid to the floor.

 

This single-piece construction delivers the category's defining benefits:

 

  • No tank-to-bowl gasket — the most common leak point in a two-piece toilet simply does not exist on a one piece. Over a 20-30 year service life, this reduces maintenance calls by eliminating the one component most likely to fail.
  • Seamless exterior — the uninterrupted surface from tank to bowl means no crevice where moisture, dust, or mold can accumulate. Cleaning is faster and more thorough — a single pass covers the entire exterior surface.
  • Streamlined visual profile — the one piece toilet sits lower and presents fewer visual interruptions than a two-piece. Architects and interior designers specify one piece toilets for contemporary bathrooms where the fixture itself is part of the aesthetic statement.

 

The trade-off for the buyer is shipping volume: a one piece toilet occupies more container space per unit than a two-piece because the tank cannot be packed separately. YingJie optimizes carton dimensions per model to maximize container fill, and offers consolidated shipping with basins, bidets, and other bathroom products to balance container utilization and minimize per-unit landed cost.

 

Six Flush Technologies — Choose the Right System for Every Specification
 

Tornado Flush

Two angled jets create a 360° rotational vortex. Maximum bowl coverage with minimum water — the most popular flush technology in the line. S-trap only. Available across the widest range of models from entry-level to premium.

Siphonic Flush

Vacuum-assisted trapway evacuation — quiet, odour-contained, and proven in residential bathrooms worldwide. Standard dual-flush at 3/6L. Available in S-trap and limited P-trap (8cm clearance). The smooth, silent option for bedrooms and ensuite bathrooms.

Washdown Flush

Gravity-driven with a wide trapway. Fewer moving parts. Lower water-pressure tolerance. The preferred system for commercial washrooms, public facilities, and regions with inconsistent water pressure. Available in both S-trap and P-trap configurations.

Double Hole Eddy

Two precision-angled jets positioned to create overlapping flush paths. More coverage than a single-jet system, simpler plumbing than a four-hole system. Available in S-trap and P-trap. The middle ground between Tornado coverage and Washdown reliability.

One Hole Eddy

A single powerful jet producing a complete rotational wash — the simplest eddy design with the fewest potential blockage points. Dedicated range of 11 models (YJ-7046 through YJ-7056) available in both S-trap and P-trap. Compact, efficient, cost-effective.

Four Hole Eddy

Four jets distributed around the bowl perimeter for the maximum possible flush coverage from an eddy system. The top-tier flush technology in the line. Available on premium models (YJ-7015). Specified for luxury residential, boutique hotels, and projects where flush performance is the primary specification criterion.

 

Drainage Options — S-Trap & P-Trap Explained

One of the most common procurement errors in international toilet sourcing is ordering the wrong drainage pattern. YingJie's one piece line eliminates this risk by offering both configurations across multiple rough-in distances:

 

S-Trap (Floor Outlet)

Waste pipe exits through the floor. Rough-in distance (wall to drain centre) available at 150mm, 200mm, 250mm, 300mm, 305mm, and 400mm — covering every major global standard. Used with Tornado, Siphonic, Double Hole Eddy, and some One Hole Eddy models. The most common configuration worldwide.

P-Trap (Wall Outlet)

Waste pipe exits through the wall at 180mm centre height. Standard in European bathrooms, increasingly common in modern commercial construction globally. Available on Washdown, Double Hole Eddy, and One Hole Eddy models. Important: Tornado and Siphonic flush types are not available in P-trap — confirm your flush system before selecting P-trap drainage.

 

Tip: When ordering for a market you are unfamiliar with, confirm the local rough-in standard with your installer before placing the order. A 50mm difference in rough-in measurement is the difference between a perfect fit and a return shipment.

 

Advantages of One Piece Toilets — Engineered for the Long Term
 

No Gasket — No Long-Term Leak Risk

The tank-to-bowl gasket on a two-piece toilet is a rubber seal that compresses with age, hardens with chemical exposure, and eventually leaks. A one piece toilet has no such joint. For property managers, facility teams, and homeowners, this eliminates the #1 service call on toilets: water on the floor from a failing tank seal.

Faster, More Thorough Cleaning

The continuous ceramic surface from tank lid to bowl base has no crevice, gap, or bolt cover where cleaning cloths catch or residues accumulate. One wipe passes uninterrupted. For hotels where housekeeping time per room directly affects operating margin, this is a measurable efficiency gain.

Contemporary Design Language

The low-profile, uninterrupted silhouette of a one piece toilet reads as "designed" rather than "assembled." Architects specify one piece toilets when the bathroom is visible — open-plan suites, glass-walled ensuites, hotel bathrooms where the fixture contributes to the visual experience. The one piece aesthetic signals a higher tier of specification than a two-piece.

Water-Efficient Dual Flush Standard

3/6 litre dual flush is standard across all models — half flush for liquid waste, full flush for solid. WELS-rated models available for the Australian market. Combined with a 3" flush valve delivering higher flow rate at lower volume, the system achieves effective waste removal within water-efficiency targets for every regulated market.

Comfort-Height Seating

Bowl rim height of 400-430mm on most models provides a seating position closer to a standard chair — easier to sit down and stand up, particularly for elderly users, people with mobility limitations, and taller adults. An increasingly standard specification across residential and accessible bathrooms worldwide.

Multi-Market Certification

CE for Europe. Watermark for Australia and New Zealand. SASO for Saudi Arabia and GCC. WELS for Australian water efficiency. ISO9001 for quality management. One toilet — pre-certified for your target market, with documentation available at order. No post-purchase testing at your cost.

 

Where One Piece Toilets Deliver the Highest Value

Residential Homes & Apartments

The one piece toilet is the standard upgrade choice in residential construction globally. The seamless design appeals to homeowners who want a bathroom that looks considered, not builder-grade. The no-gasket construction appeals to property developers who want to minimize maintenance callbacks over the warranty period. Compact models (YJ-7019 at 590mm depth) fit small bathrooms without sacrificing comfort height or flush performance.

Hotels & Hospitality

In hotel bathrooms, a one piece toilet communicates a higher standard of specification than a two-piece — a detail that contributes to guest perception of room quality. The seamless surface simplifies housekeeping. Soft-close seats eliminate the "slam" noise that travels between rooms. For boutique hotels, water-transfer decorative patterns or custom color-matched toilets reinforce brand identity at the fixture level.

Commercial & Office Buildings

Washdown flush models handle high-traffic cycles without clogging. The one piece design eliminates the tank gasket — the most common maintenance failure in commercial washrooms. For specifiers, CE-marked models simplify compliance documentation for commercial building permits across European markets.

Healthcare & Aged Care

Comfort-height seating reduces strain for patients and residents. The seamless, crevice-free surface supports infection-control cleaning protocols. Watermark-certified models are pre-approved for Australian healthcare facilities, eliminating the certification step from the procurement timeline.

Retail & Wholesale Distribution

For bathroom retailers and plumbing wholesalers, the one piece line's depth — 60+ models across 6 flush types and multiple rough-in distances — means one supplier covers every customer's requirements. Mixed-container orders across models reduce per-unit freight. Private-label OEM with custom branding and packaging creates a house-brand line without manufacturing investment.

FAQ

 

Q: What is the difference between this one piece line and the CUPC-certified line?

A: The CUPC line is a focused range of 9 models engineered specifically for the North American market — CUPC-listed, WaterSense-certified at 1.28 GPF, ADA-compliant, and MaP-tested, with a single S-trap 12" rough-in. This global line offers 60+ models with 6 flush technologies, both S-trap and P-trap drainage, and multiple rough-in distances — certified for Europe (CE), Australia (Watermark/WELS), the Middle East (SASO), and other international markets. Choose the CUPC line for US/Canada projects; choose this line for everywhere else.

Q: Which flush technology should I choose?

A: Tornado is the most popular — 360° bowl coverage, visually impressive, and available on the widest range of models. Siphonic is the quietest — ideal for ensuite bathrooms and hotels where flush noise matters. Washdown is the most reliable under low water pressure — preferred for commercial and public washrooms. Double Hole Eddy balances coverage and reliability. One Hole Eddy is the most compact and cost-effective. Four Hole Eddy is the premium option for maximum flush coverage.

Q: Can I get both S-trap and P-trap in the same model?

A: It depends on the flush type. Washdown, Double Hole Eddy, and One Hole Eddy models are available in both S-trap and P-trap. Tornado and Siphonic models are S-trap only. When placing your order, confirm the drainage pattern (S-trap with rough-in distance, or P-trap at 180mm) — this cannot be changed after manufacturing.

Q: What certifications do these toilets carry?

A: CE (European conformity), Watermark (Australian plumbing standard), SASO (Saudi/GCC), WELS (Australian water efficiency), ISO9001 (quality management), ISO14001 (environmental management), and ISO45001 (occupational health and safety). If your market requires a certification not listed here, contact us — we have compliance experience in 50+ countries and can advise on feasibility.

Q: What is the MOQ and lead time?

A: MOQ: 50 units per model. Mixed-container orders combining different models are supported to reach minimum quantity. Lead time: 30 days for standard models up to 1,000 units; negotiable for larger quantities. Custom color, water-transfer decoration, or branded OEM orders add approximately 45 days for sample development. We accept T/T (30% deposit, balance before shipment) and L/C at sight.

Q: Can I customize the toilet with water-transfer decoration or custom colors?

A: Yes. Water-transfer ceramic decoration is available on select models — patterns, textures, or decorative designs applied to the ceramic surface. Custom Pantone color matching is available for bulk OEM orders. Color edging on the bowl rim is available as a detail option. MOQ varies by specification — contact our sales team with your design brief for a feasibility assessment and quotation.

Q: What water parts do you use?

A: Standard specification uses OEM-grade flush and fill valves. WDI premium water parts are available as an upgrade — WDI is a tier-1 Chinese water-parts manufacturer. R&T and Geberit-compatible valve configurations are also available. UF (urea-formaldehyde) seat covers can be upgraded from standard PP for a harder, more scratch-resistant surface with a heavier, more premium feel.

Q: How does a one piece toilet compare to a two piece for shipping cost?

A: A one piece toilet is heavier and occupies more carton volume per unit than a two-piece because the tank cannot be packed separately. However, the per-unit freight difference must be weighed against three factors: the one piece commands a higher retail price in most markets, it eliminates the #1 warranty claim (tank gasket leaks), and YingJie's carton optimization and consolidated-container shipping (mixing with basins, bidets, etc.) offset the volume disadvantage. Contact our logistics team with your model list and destination for a precise landed-cost calculation.
