The COBRA Slim Concealed Cistern is engineered for modern bathrooms where space efficiency, strength, and reliability are essential. Featuring an ultra-slim 85 mm profile, this cistern is ideal for solid wall installations and wall-hung toilet applications, delivering a clean, minimalist finish once concealed.

Designed for front actuation, the cistern supports wall-hung toilet pans with adjustable fixing distances of 180 mm or 230 mm, ensuring compatibility with standard installations. An insulated cover prevents condensation from forming on the tank, protecting surrounding walls and finishes over time.

The flush volume is fully adjustable (6L / 4.5L / 3L / 4.2L), offering excellent water-saving performance without compromising flushing efficiency. Once correctly installed into a solid wall, the system provides a load-bearing capacity of up to 400 N (approximately 407.89 kg). The internal sheet metal frame acts purely as a framework and does not carry the toilet’s load.

Supplied with a DZR brass angle valve and a 90-degree bent outlet, this COBRA concealed cistern meets quality and durability expectations for both residential and commercial bathroom installations.
