Roca Ona WC cistern – comfort and water saving

This Roca Ona cistern is the perfect solution for those who value both functionality and modern design. Designed for bowls from the Ona series, it combines comfort with environmental care thanks to dual flush. Hidden water inlet from below is not only an aesthetic look, but also facilitates installation and maintenance.

Construction and functionality

The Roca Ona cistern is characterized by a solid construction and a well-thought-out flushing solution. The dual-button system allows you to choose the amount of water – 4.5 liters for a full flush and 3 liters for an economical flush. This division ensures optimal water consumption, reducing costs and environmental impact. The position of the water inlet from below eliminates the visibility of unsightly hoses, which translates into a neat appearance of the entire installation. In addition, the cistern is compatible with Roca Ona series toilet bowls, which guarantees a perfect fit and easy installation.

Finishing and durability

The cistern is made of high-quality sanitary ceramic in white color, which ensures durability and ease of cleaning. The SUPRAGLAZE® finish is an innovative coating that creates a smooth and non-porous surface, preventing the build-up of scale and limiting the development of bacteria. This translates into hygiene and minimal effort during cleaning. The manufacturer's warranty is 5 years, which proves the high quality of the product and confidence in its reliability.
