Wall-frame cistern support CERSANIT AQUA 50 MECH QF K97-525 for concealed toilet installation

CERSANIT AQUA 50 MECH QF K97-525 is a wall-frame cistern support engineered for concealed toilet installation. The unit integrates a sturdy metal mounting frame with a mechanical flush cistern, enabling installation of wall-hung toilets in stud partitions or solid walls. Designed to be used with compatible flush plates and wall-hung pans, the frame supports sanitary fixtures while keeping plumbing components hidden behind a finished wall surface, contributing to a space-efficient and easy-to-clean bathroom layout.

Advantages

The wall-frame design provides stable support for wall-mounted toilets while accommodating installation inside drywall or masonry walls. The mechanical flush mechanism offers reliable manual operation without the need for electrical connection. Corrosion-resistant components and adjustable mounting brackets simplify alignment and height adjustment during installation. The concealed cistern contributes to a minimalist bathroom aesthetic and reduces visible plumbing, while the frame construction allows for standardized attachment of compatible ceramic pans and flush plates.

• Renovations where space-saving, wall-hung toilets are required
• New-build bathrooms with stud partition walls

• Bathrooms needing a stable mounting solution for wall-mounted toilet pans

How to use

Install the frame at the required height and secure it to floor and wall substrate using the adjustable mounting brackets.

Usage recommendations

Use with flush plates and wall-hung pans that are compatible with concealed cistern frames. Ensure installation by a qualified plumber or installer and follow local building regulations. Verify wall construction and fixings are appropriate for the chosen installation depth and load requirements, and perform leak tests after connecting the water supply.
