Product Overview

The Oliveri UNI-A2-BY Wall Mixer In-Wall Body Only is the concealed SERIES 2 foundation for compatible London, Paris and Venice wall mixer trim kits. Installed during first-fix plumbing, it allows the visible trim style and finish to be selected separately once the surrounding bathroom surfaces are complete.

Oliveri’s flexible unibody system lets compatible trim colour or design be changed later without replacing the concealed body. This provides useful freedom during a renovation or new build while keeping the wall mixer installation clean and coordinated.

Made from lead-free brass and fitted with a 35mm Kerox ceramic-disc cartridge, the UNI-A2-BY is designed for dependable control between 150 and 500kPa. It is not compatible with Verona wall mixer trim kits, which require the separate SERIES 1 concealed platform.

Extra Information

The UNI-A2-BY supports a staged specification process. Builders can complete the concealed first-fix installation while homeowners or designers retain more time to choose between compatible London, Paris and Venice trims.

Its SERIES 2 compatibility also creates flexibility after installation, allowing a compatible trim style or finish to be refreshed without specialist tools or replacement of the concealed body. Always confirm the correct platform before closing the wall.
