6 Technical Core Highlights of Model TAITAO-CT10603
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 an ultra-dense porcelain core with low moisture absorption (<0.2%), preventing odor penetration and glaze micro-cracking over decades.
High-Efficiency Rimless Washdown Flush
Open-rim bowl design allows water to wash across the entire ceramic surface from rim to outlet — no hidden rim cavity for bacteria or limescale. High-efficiency washdown flushing with Dual Flush 4/6 LPF keeps operating costs low.
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 (default). 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. The 102 mm waste outlet diameter matches common European pan connectors and installation standards.
UF/PP Soft-Close Seat with Quick Release
Supplied with a durable UF or PP soft-close seat featuring a quick-release hinge for easy deep cleaning. The soft-square bowl provides a contemporary squared look and comfortable seating geometry.
Two-Piece Rimless Soft-Square Back-To-Wall Design
A modern two-piece form with close-coupled ceramic cistern and rimless soft-square bowl. The 660 × 375 × 845 mm footprint suits standard bathroom layouts, while the 47.85 KG net weight balances durability with straightforward handling.
Where CT10603 Works Best
From family bathrooms and rental properties to food-service and showroom specification, the two-piece rimless back-to-wall CT10603 suits global projects — close-coupled ceramic cistern, rimless soft-square bowl, 180 mm P-trap rough-in, 4/6 LPF dual flush, and three finish options.
Residential Apartments & Homes
The rimless soft-square bowl and full-size 660 mm length suit everyday family bathrooms, while the close-coupled cistern keeps installation simple and maintenance accessible. Rimless washdown flushing and 4/6 LPF dual flush reduce daily water use and cleaning effort.
Airbnb & Short-Term Rentals
Hosts benefit from a familiar two-piece form that guests intuitively understand, plus an open-rim bowl with no hidden rim cavity for faster, more thorough cleaning between check-ins. The soft-close seat and dual-flush cistern also cut noise complaints and utility costs.
Restaurants & Food Premises
Cafés, restaurants and commercial washrooms where hygiene audits matter. The rimless bowl and fully glazed trapway reduce hidden dirt traps, while high-efficiency washdown flushing supports efficient daily sanitisation.
Showrooms & Specification Projects
Architects and wholesalers specifying for residential developments. The two-piece rimless back-to-wall form, soft-square bowl, three finish options and global certifications (CE / UKCA / cUPC / WaterMark) provide a standards-compliant, easy-to-source choice.

Low-Maintenance Hygiene by Design
TAITAO-CT10603 is engineered for low-maintenance hygiene. The open-rim (rimless) bowl, fully glazed trapway and optional nano self-cleaning glaze eliminate the hidden rim cavity where dirt and limescale usually hide — so routine care stays quick and chemical-light.
Rimless bowl
With no boxed rim cavity, the entire bowl interior is visible and reachable. A simple wipe around the rim line and bowl surface 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 & cistern lid
Wipe the UF/PP seat and cistern lid with a damp cloth and mild detergent, then dry. Do not soak the hinges, and avoid solvent-based sprays on the seat cover.
CT10603 Matching Components
Model CT10603 is a two-piece toilet supplied with its own close-coupled 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.
UF/PP Soft-Close Seat
Pairs with our urea-formaldehyde (UF) or polypropylene (PP) 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 CT10603 uses a 4 L / 6 L dual-flush system paired with a rimless soft-square bowl and fully glazed 102 mm trapway. A rimless washdown bowl needs less water 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 LPF
A 4 L partial flush for liquid waste and a 6 L full flush for solids. Compared with older 9-13 L single-flush WCs, daily household toilet water use is typically reduced by 20-30%.
Soft-Square Bowl Geometry
The soft-square bowl interior is designed to work with the rimless washdown flush for efficient water coverage, helping a single flush clear the bowl effectively.
Fully Glazed Trapway
A 102 mm fully glazed internal passage reduces blockages and repeat flushes, so a single flush is usually enough.
