6 Technical Core Highlights of Model TAITAO-CT10603C
Every detail engineered to satisfy rigid Western plumbing codes, zero-defect quality control, and effortless sanitation maintenance.
1280°C Tunnel-Kiln Vitrification
Formed from premium vitreous china and fired at 1280°C in tunnel kilns, yielding a dense porcelain body with moisture absorption below 0.2% — guarding against odour soak-in and glaze crazing across decades of use.
Rimless High-Efficiency Washdown
The open-rim design sweeps water across the whole bowl surface from rim to outlet — no concealed rim cavity for microbes or scale. Dual Flush 4/6 LPF keeps running costs low while meeting EU/UK/AU efficiency marks.
Standard & Optional Nano Glaze
Select the ceramic surface to match project tier and budget: 1. Standard High-Gloss Vitreous Glaze (default). 2. Nano Self-Cleaning Antibacterial Glaze (optional, on request).
P-Trap Outlet & Fully Glazed Trapway
A 180 mm P-trap wall outlet and a fully glazed internal channel evacuate waste reliably. The 102 mm outlet diameter aligns with common European pan connectors and fitment standards.
UF/PP Soft-Close Seat, Quick Release
Fitted with a durable UF or PP soft-close seat and quick-release hinge for fast deep cleaning. The soft-square bowl brings a contemporary squared profile and comfortable seating geometry.
Two-Piece Rimless Soft-Square Back-To-Wall
A modern two-piece silhouette with close-coupled ceramic cistern and rimless soft-square bowl. The 660 × 375 × 845 mm envelope fits standard bathroom plans, while the 48.25 KG net weight balances robustness with easy handling.
Where CT10603C Works Best
From family bathrooms and rental properties to food-service and showroom specification, the two-piece rimless back-to-wall CT10603C 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-CT10603C is designed for low-effort hygiene. The open-rim (rimless) bowl, fully glazed trapway and optional nano self-cleaning glaze remove the hidden rim cavity where grime and limescale usually collect — so daily upkeep stays quick and light on chemicals.
Rimless bowl
No boxed rim cavity means the whole bowl interior is open and reachable. A quick wipe along the rim line and bowl face handles everyday cleanliness.
Optional nano glaze
Available with an optional nano self-cleaning antibacterial glaze. Its smooth, low-porosity skin resists stain and scale adhesion, cutting scrub time.
Gentle daily cleaning
Use a mild, non-abrasive liquid cleaner with a soft sponge or cloth. Avoid steel wool, scouring powders and long 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 keep solvent sprays off the seat cover.
CT10603C Matching Components
Model CT10603C is a two-piece toilet supplied with its own close-coupled ceramic cistern (tank) — pan and tank ship as one matched set. No concealed in-wall frame or wall actuator plate to source. The standard accessories below are quoted and supplied with the unit.
UF/PP Soft-Close Seat
Matched with our urea-formaldehyde (UF) or polypropylene (PP) soft-close seat with quick-release hinge — durable, hygienic and quiet. Supplied with the pan or specified per project.
Dual-Flush Push Button
The 4 L / 6 L dual flush is driven by a push button on the cistern lid — no separate wall plate needed. Mechanical actuation, pneumatic option available.
Cistern Internals Kit
Inside the tank, a fill valve and flush (discharge) valve complete the dual-flush mechanism, compatible with common 1/2" supply lines and local plumbing norms.
Pan Connector & Inlet Hose
The 180 mm P-trap wall outlet meets 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 CT10603C pairs a 4 L / 6 L dual-flush system with a rimless soft-square bowl and a fully glazed 102 mm trapway. A rimless washdown bowl needs less water for a full rinse, lowering operating cost and environmental load without sacrificing 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. Against older 9-13 L single-flush WCs, daily household toilet water use typically drops 20-30%.
Soft-Square Bowl Geometry
The soft-square bowl interior works with the rimless washdown flush for efficient water coverage, helping one flush clear the bowl.
Fully Glazed Trapway
A 102 mm fully glazed internal passage reduces blockages and repeat flushes, so a single flush is usually enough.
