Matte Black Wall-Hung Toilet – Technical Overview

Wall-hung toilets eliminate the floor-mounted base, allowing the bowl to be suspended from a concealed carrier system. This configuration reduces floor‑cleaning time and improves accessibility in commercial restrooms.

The fixture is formed from vitreous china fired at over 1200 °C, providing a dense, non‑porous body with a typical compressive strength exceeding 80 MPa. A high‑temperature ceramic glaze is applied and then a matte black pigment is fused into the glaze layer, resulting in a surface hardness of approximately 6 Mohs and resistance to common cleaning chemicals.

Overall dimensions conform to a standard wall‑hung footprint: bowl width 360 mm, depth 540 mm, and height from finished floor to top of seat 420 mm (adjustable via carrier). The concealed steel frame is rated for a static load of 400 kg, and the rough‑in distance for the waste outlet is typically 180 mm from the finished wall.

Flushing performance uses a dual‑flush valve offering 3 L for a reduced flush and 6 L for a full flush, delivering a trapway diameter of 55 mm to prevent clogging. Water consumption meets the ≤6 L per full flush requirement of most regional water‑efficiency standards.

Installation requires a compatible concealed carrier bolted to load‑bearing studs or a concrete wall, with the water supply inlet positioned 150 mm above the finished floor and the waste outlet aligned to the carrier’s outlet pipe. Proper sealing of the wall‑penetration with a flexible gasket prevents moisture ingress, and the carrier’s height adjustment allows fine‑tuning of the bowl position within ±10 mm.

Typical applications include high‑traffic public restrooms, healthcare facilities, hospitality venues, and educational institutions where floor space is at a premium and stringent hygiene protocols are required. The smooth, joint‑free surface minimizes harboring of pathogens and facilitates rapid disinfection with standard hospital‑grade cleaners.

Factory testing encompasses hydrostatic pressure tests at 1.5 times working pressure, impact resistance tests using a 5 kg steel ball dropped from 1 m, and glaze adhesion assessments via cross‑hatch tape testing. Dimensional inspection is performed on a coordinate‑measuring machine with a tolerance of ±0.5 mm for critical mounting holes.

Optional configurations include a choice of soft‑close seats in polypropylene or stainless steel, alternative flush actuators (push‑button, lever, or infrared), and accessory kits such as concealed cisterns with adjustable water‑saving settings.

Key Features

• Space‑saving wall‑mounted design eliminates floor pedestal.
• Matte black finish provides a uniform, non‑reflective appearance suitable for modern architectural schemes.
• Dual‑flush valve reduces water usage while maintaining effective waste removal.
• High‑strength vitreous china body resists chipping and chemical attack.
• Concealed steel carrier simplifies installation and supports heavy loads.

Frequently Asked Questions

Can the bowl height be adjusted after installation?

Yes, the carrier includes height‑adjustment brackets that allow ±10 mm vertical movement without removing the bowl.

What materials are available for the seat?

Standard options are polypropylene with soft‑close hinges and stainless steel for high‑impact environments; both are compatible with the matte black bowl.

How is the matte black finish tested for durability?

Finish durability is verified via 500 cycles of abrasion testing with a non‑scratch pad and chemical resistance testing against common janitorial agents (pH 4–10).
