B2B Back to Wall Bidet Toilet

A back-to-wall bidet toilet combines a toilet bowl and bidet functionality in a single unit that mounts flush against the wall, concealing the cistern and plumbing. This configuration reduces floor‑space requirements and simplifies cleaning in commercial restrooms. Typical installations are found in hotels, office buildings, and healthcare facilities where water efficiency and hygiene are priorities.

Technical Specifications

Seat height (from floor)	400 mm (standard comfort height)
Overall dimensions (W × D × H)	380 mm × 560 mm × 420 mm
Approx. weight	25 kg
Glaze thickness	0.2 mm (typical)

Design and Installation Considerations

The concealed cistern is accessed via a service panel located at the top or side of the unit, allowing maintenance without removing the fixture. Wall‑mounted brackets must support the combined weight of the bowl, cistern, and bidet mechanism, typically rated for at least 150 kg. Proper alignment of the outlet with the waste pipe is critical to prevent leaks and ensure efficient siphonic action.

The bidet nozzle is positioned to provide a spray radius of approximately 80 mm from the bowl rim, with adjustable angle settings ranging from 0° to 15° for user comfort. Water temperature can be controlled via a mixing valve that connects to hot and cold supplies, allowing a range of 20 °C to 45 °C. Anti‑siphon protection is integrated to prevent backflow into the potable water system.

Materials and Finishes

The bowl and cistern are formed from vitreous china fired at approximately 1250 °C, resulting in a non‑porous surface resistant to staining and chemical attack. A clear glaze layer of about 0.2 mm thickness provides a smooth finish that facilitates easy cleaning. Seat and lid options typically include polypropylene with soft‑close hinges or urea‑formaldehyde for higher impact resistance.

• Vitreous china bowl with anti‑bacterial glaze (optional)
• Polypropylene seat with stainless‑steel hinges
• Urea‑formaldehyde seat for high‑traffic environments
• Chrome‑plated brass bidet nozzle assembly

Performance and Compliance

The dual‑flush system delivers an average water consumption of 3.8 L per user per day in typical office settings, representing a reduction of up to 45 % compared with single‑flush 6 L units. Flush noise is measured below 55 dB(A) at the fixture, meeting typical acoustic requirements for office restrooms. The product is designed to satisfy the dimensional and performance criteria of common international sanitary ware standards.

Typical Applications

In hospitality environments, the back‑to‑wall layout minimizes visual clutter and allows flexible interior design while providing guests with integrated bidet hygiene. Office buildings benefit from reduced water bills and lower maintenance due to the concealed cistern’s easy access panel. Healthcare facilities value the smooth, seamless surfaces that facilitate infection control protocols.

• Hotels and resorts – guest rooms and suites
• Corporate office towers – restroom floors
• Healthcare centers – patient wards and staff facilities
• Educational institutions – dormitory bathrooms

Quality Assurance

Each unit undergoes a hydrostatic pressure test at 0.6 MPa to verify leak‑free performance of the cistern and bidet valve. Dimensional checks are performed on critical features such as outlet alignment, seat mounting holes, and nozzle spray angle using calibrated CMM equipment. Visual inspection of the glaze surface is conducted under 500 lux lighting to detect any pinholes or inclusions.

Statistical process control is applied to the glaze thickness and firing temperature, with control limits set at ±0.02 mm and ±10 °C respectively. Finished goods are sampled for flush performance, verifying that the full‑flush volume remains within 5.5–6.5 L and the reduced‑flush within 2.5–3.5 L over 200 cycles.

Customization Options

Custom rough‑in distances can be accommodated from 250 mm to 400 mm to match specific plumbing layouts. Bowl length and width are adjustable within ±20 mm while maintaining structural integrity. Flush volumes can be tuned to 4–6 L for full flush and 2–4 L for reduced flush upon request. Optional features include touch‑free sensor activation for the bidet spray and heated seat elements with adjustable temperature settings.

• Alternative glazes: matte, anti‑slip, or colored finishes
• Seat materials: bamboo‑filled polypropylene, recycled polyamide
• Integrated deodorizing cartridge or UV‑light sanitizer
• Custom branding or logo embossing on the cistern cover

Frequently Asked Questions

Q: Can dimensions be customized?
A: Yes, rough‑in distance, bowl length, and width can be adjusted within specified limits; contact engineering with site drawings.

Q: What information is required before quotation?
A: Required data include rough‑in measurement, desired flush volume, seat material preference, and any optional features such as sensor activation or heated seat.

Q: What materials are available for the bowl and seat?
A: Bowl is vitreous china; seat options are polypropylene, urea‑formaldehyde, or recycled polyamide; glaze can be standard clear, matte, or anti‑bacterial.

Q: How is quality inspected?
A: Each unit receives hydrostatic pressure testing, dimensional verification via CMM, and visual glaze inspection under controlled lighting.

Q: What packaging methods are available for export shipments?
A: Units are packed in double‑wall corrugated cartons with corner protectors, placed on pallets and stretch‑wrapped; optional wooden crates are available for high‑risk destinations.
