Toilet bowl CERSANIT WC KNEE AQUA SYSTEM 40/50, wall-mounted/close-coupled options

CERSANIT WC KNEE AQUA SYSTEM 40/50 is a toilet bowl engineered for compatibility with standard 40 cm and 50 cm plumbing outlet positions. Designed by CERSANIT for residential and light-commercial bathrooms, the bowl accepts both wall-mounted and close-coupled installation configurations and is intended to be paired with compatible cisterns, seats and mounting fittings. The ceramic surface is manufactured for regular sanitary use and to ensure consistent water flow and waste evacuation performance when installed according to manufacturer guidelines.

Advantages

The design supports two common installation types—wall-mounted and close-coupled—allowing flexibility during bathroom planning or renovation. Compatibility with 40/50 cm outlet distances simplifies replacement of existing fixtures without the need for major alterations to waste plumbing. The ceramic construction provides a smooth, easy-to-clean surface and reliable durability for everyday use. The bowl’s geometry is shaped to promote efficient flushing and reduce residue retention when paired with appropriately sized cisterns and installation fittings.

Suitable for

• Residential bathrooms requiring a replacement bowl with 40 cm or 50 cm outlet compatibility
• Light-commercial washrooms where wall-mounted or close-coupled fixtures are preferred
• Bathroom renovations where minimal plumbing modifications are desired
• Installations that will use matching CERSANIT seats, cisterns and mounting hardware

How to use

Select the installation type (wall-mounted or close-coupled) that matches your bathroom layout and ensure the outlet distance aligns with either 40 cm or 50 cm specifications. Fit the bowl using the appropriate mounting kit or brackets and connect the water supply and waste outlet following installation instructions provided by the cistern and fitting manufacturers. Install a compatible toilet seat and cistern, check all seals and fastenings for leaks, and perform a test flush to confirm correct water flow and evacuation. Maintenance consists of routine cleaning with non-abrasive cleaners and periodic inspection of mounting fixings and seals.

Usage recommendations

Use manufacturer-recommended installation fittings and a compatible cistern and seat to ensure proper function and maintain warranty conditions; avoid aggressive abrasive cleaners that can damage the glaze and follow local plumbing regulations when performing installation.
