Product Overview

The Oliveri UNI-B1-BY Verona Wall Mixer with Diverter In-Wall Body Only is the concealed SERIES 1 control assembly for a compatible Verona mixer-and-diverter finishing trim kit. Installed behind the finished wall, it supports the control of water flow, temperature and switching between two connected outlets.

Oliveri’s Verona unibody platform allows the visible trim finish to be selected separately and changed later across compatible Verona options. This is especially useful in staged bathroom projects where plumbing rough-in happens before final tapware colours are confirmed.

Constructed from lead-free brass and fitted with a 35mm Kerox ceramic-disc cartridge, the body is designed for dependable performance between 150 and 500kPa. It must be paired with the correct Verona wall mixer with diverter trim kit.

Extra Information

This concealed body suits bathrooms that need one mixer to control two water outlets, such as an overhead shower and hand shower. The diverter function keeps the finished wall arrangement streamlined while providing a clear way to select the desired outlet.

Installing the UNI-B1-BY during first fix leaves the visible Verona finish decision until later in the project. Confirm the exact compatible trim and outlet layout before wall linings are completed.
