Custom Ceramic Glaze Matching
Standard white stock finish, with custom colors available on requestTwo-Piece Rimless Back To Wall Toilet Manufacturer | cUPC CE UKCA WaterMark WC TAITAO-CT11815C
The CT11815C anchors a master bathroom with real substance: a two-piece rimless back-to-wall pan weighing 51 kg of solid vitreous china, finished with a fully glazed trapway and a high-efficiency washdown flush. The rimless bowl does away with the under-rim cavity entirely — every wettable surface stays visible and accessible, so cleaning is quicker and bacteria have no hidden corner to colonise. A 4/6L dual flush keeps water use honest, and the UF soft-close seat drops silently. Built around the 180mm P-trap standard for European and UK installs, and cUPC, CE, UKCA and WaterMark available on request for wholesale and OEM supply.

6 Technical Core Highlights of Model TAITAO-CT11815C
Every detail engineered to satisfy rigid Western plumbing codes, zero-defect quality control, and effortless sanitation maintenance.
1280°C Tunnel Kiln Vitrification
Cast from premium vitreous china ceramic formulations and vitrified at 1280°C in tunnel kilns. Results in ultra-dense porcelain core with low moisture absorption (<0.2%), preventing odor penetration and glaze micro-cracking over decades.
High-Efficiency Rimless Washdown Flush
High-efficiency washdown flushing with a rimless bowl design — water sweeps the full inner surface without a hidden rim cavity, improving hygiene and cleanability. Features Dual Flush 4/6L water consumption.
Standard & Nano Self-Cleaning Glaze Options
We offer flexible ceramic surface specifications for OEM/ODM orders so you can select the ideal glaze according to project tier and budget requirements: 1. Standard High-Gloss Vitreous Glaze. 2. Nano Self-Cleaning Antibacterial Glaze (optional, on request).
P-Trap Wall Outlet & Fully Glazed Trapway
The 180 mm P-trap wall outlet and a fully glazed internal passage help ensure solid waste is evacuated efficiently. Internal glazed-trapway diameter is project-specific — please share your market standards so we can confirm the matching geometry.
UF Soft-Close Seat with 3-Sec Quick Release
Manufactured from premium Urea-Formaldehyde resin matching the porcelain texture. Features stainless steel soft-close hinges designed for long-cycle operation, with a one-button quick release for effortless deep bowl cleaning.
Two-Piece Back-To-Wall Skirted Design
Engineered as a two-piece back-to-wall WC with a smooth exterior apron that covers the side trapway contours completely against the wall. Eliminates dust-collecting grooves and awkward crevices, reducing cleaning time by up to 70%.
Where CT11815C Works Best
From compact city apartments to hospitality and food-service washrooms, the rimless back-to-wall CT11815C is engineered for international projects — 180 mm P-trap rough-in, 4/6 L dual flush, and cUPC / CE / UKCA / WaterMark aligned performance.
Residential Apartments & Homes
Design-led homes increasingly expect rimless as standard. The back-to-wall silhouette reads modern and premium, while the 4/6 L dual flush and fully glazed 180 mm P-trap keep running costs and upkeep low for owners.
Airbnb & Short-Term Rentals
Holiday-let hosts win on cleanliness reviews. With no hidden rim cavity, turnaround cleaning is faster and more thorough between guests — and the compact integrated-tank back-to-wall look photographs well for listings.
Restaurants & Food Premises
Cafés, restaurants and commercial kitchens where hygiene audits matter. Rimless removes a known bacterial harbour point and pairs with the optional nano self-cleaning glaze for easier daily sanitisation.
Showrooms & Specification Projects
Architect and showroom specification work. The rimless, integrated-cistern back-to-wall form is the current premium standard, giving specifiers a defensible, standards-compliant (cUPC / CE / UKCA / WaterMark) choice to present to clients.

Low-Maintenance Hygiene by Design
TAITAO-CT11815C is engineered for low-maintenance hygiene. The rimless bowl, fully glazed trapway and optional nano self-cleaning glaze reduce the surfaces where dirt and limescale can accumulate — so routine care stays quick and chemical-light.
Rimless bowl
With no rim cavity, there is no hidden channel for bacteria or residue. A quick wipe of the open rim and bowl interior after use is enough for daily hygiene.
Optional nano glaze
Available with an optional nano self-cleaning antibacterial glaze. Its smooth, low-porosity surface helps resist stain and limescale adhesion, cutting down on scrubbing.
Gentle daily cleaning
Use a mild, non-abrasive liquid cleaner with a soft sponge or cloth. Avoid steel wool, scouring powders and prolonged contact with bleach or strong acids that can dull the glaze.
Seat & hinges
Wipe the UF soft-close seat with a damp cloth and mild detergent, then dry. Do not soak the hinges, and avoid solvent-based sprays on the seat cover.
CT11815C Matching Components
Model CT11815C is a two-piece back-to-wall toilet supplied with its own integrated ceramic cistern (tank) — pan and tank ship as a matched set. There is no concealed in-wall cistern frame or wall-mounted actuator plate to source. The standard accessories below are quoted and supplied together with the unit, and the seat ring height is fixed by the ceramic body itself.
UF Soft-Close Seat
Pairs with our urea-formaldehyde (UF) soft-close seat with quick-release hinge — durable, hygienic and silent. Supplied with the pan or specified per project.
Dual-Flush Push Button
The 4 L / 6 L dual flush is operated by a dual push button seated on the cistern lid — no separate wall actuator plate required. Mechanical actuation, pneumatic option available.
Cistern Internals Kit
Inside the tank, a standard fill valve and flush (discharge) valve complete the dual-flush mechanism, compatible with common 1/2" supply lines and local plumbing standards.
Pan Connector & Inlet Hose
The 180 mm P-trap wall outlet connects to the drainage via a standard pan connector and outlet seal, while a flexible inlet hose links the wall supply to the tank.
Dual Flush 4/6L — Less Water, Same Clean
Model CT11815C uses a 4 L / 6 L dual-flush system paired with a rimless bowl and fully glazed 102 mm trapway. Less water is needed for a complete rinse, lowering operating cost and environmental load without compromising hygiene. The model supports EU Water Label, UK Water Label and WELS (Australia/NZ) efficiency labelling where required.
Dual Flush 4 / 6 L
A 4 L partial flush for liquid waste and a 6 L full flush for solids. Average daily consumption stays well below older 9-13 L single-flush toilets.
Rimless Bowl
The open rim design rinses the entire bowl surface with less water and leaves no hidden cavity where bacteria can accumulate.
Fully Glazed Trapway
A 102 mm fully glazed internal passage reduces blockages and repeat flushes, so a single flush is usually enough.
