Description
Heavy-Duty Toilet Frame with Concealed Cistern
This heavy-duty toilet frame with concealed cistern is engineered for demanding wall-hung toilet installations. With a gross weight of 19 kg, the reinforced matte black steel frame provides exceptional load-bearing capacity for commercial washrooms, hotel projects and high-traffic public facilities.
Design & Aesthetics
The robust matte black frame keeps a clean, professional appearance while supporting heavier ceramic wall-hung toilets with confidence. Once concealed behind the wall, only the flush plate remains visible, preserving a minimalist bathroom design that is easy to maintain.
Material & Durability
Built with thicker gauge carbon steel than standard models, the frame offers superior rigidity and anti-corrosion protection for humid environments. The white cistern is manufactured from high-strength plastic for reliable, leak-proof flushing performance over an extended service life.

Dual Flush Water Efficiency
The concealed cistern uses a dual flush mechanism – a reduced flush for liquid waste and a full flush for solid waste – which cuts water use compared with a single-flush system. Reduced flush volumes of around 3 litres and a full flush of around 6 litres are typical for concealed cisterns, and the flush volume can be adjusted on site to match regional water-efficiency expectations. Lower water use per flush also reduces the load on the drain system in high-traffic buildings, which is why dual flush concealed systems are the standard choice for modern hotel and apartment projects.
Installation & Compatibility
Standard concealed installation: fix the frame to wall and floor, connect water and drain lines, then tile over. Compatible with standard concealed cistern flush plates – explore our toilet flush plates collection to finish the installation.
Installation Steps
This heavy-duty variant uses reinforced steel members for a higher load rating, specified where the toilet is subject to frequent or heavier use. A typical installation follows these steps:
- Position and level the frame – bolt the reinforced frame to the wall and floor – using the adjustable legs and built-in level points.
- Connect the water inlet and drain pipes to the frame’s outlets before closing the wall.
- Fit the flush mechanism and verify water-tightness with a test flush.
- Tile or plaster over the frame, leaving the access opening for the flush plate unobstructed.
- Mount the flush plate, hang the wall-hung toilet and run a full flush cycle to confirm performance.

Frequently Asked Questions
Q: How much weight can the heavy-duty frame carry?
A: The reinforced frame is engineered for a higher load rating than standard frames. Request the load rating with your quotation so it can be checked against your wall-hung toilet model.
Q: Is it suitable for commercial projects?
A: Yes – the reinforced construction is specified for hotels, public washrooms and high-traffic projects where long-term reliability and consistent installation matter.
Q: Which flush plate fits this cistern?
A: The cistern accepts standard concealed cistern flush plates; order the plate together with the frame to keep the matched pair under one warranty.
Q: Can the frame height be adjusted on site?
A: Yes — the adjustable legs allow fine height adjustment (0–220 mm), so you can set the finished seat height to about 400 mm, the recommended comfort height for most users.
Q: What flush volumes does the cistern offer?
A: The dual-flush mechanism provides a reduced flush and a full flush to balance water efficiency with performance. Exact volumes depend on your target market’s regulations and are available on request.
Q: Does the cistern work with third-party flush plates?
A: Yes — it works with most standard concealed cistern systems, including Geberit Sigma & Delta, R&T and WDI plates. All trademarks belong to their respective owners; our cisterns are independent aftermarket products.
