The Story
Zucchetti R99684 built-in part for bath-shower mixers with diverter
The Zucchetti R99684 built-in part is the technical body designed for wall-mounted single-lever bath/shower mixers with diverter. Belonging to the Zucchetti Built-in Parts category, it represents the fundamental basis for ensuring functionality, reliability, and seamless integration in built-in shower systems.
Technical structure for built-in installation
Designed to be fully integrated into the wall, the R99684 conceals all the technical components, leaving only the external part of the mixer exposed. This creates a clean, modern, and minimalist aesthetic, ideal for designer bathrooms.
The body is equipped with plastic protections for the installation and finishing phase, facilitating assembly and preventing damage during work (visible in the technical drawing on page 2).
Integrated diverter and double outlet
The built-in part integrates a system with internal diverter , which allows the management of two water outlets:
- primary outlet (e.g. shower head or bath spout)
- secondary outlet (e.g. shower)
This configuration allows for versatile and complete use of the shower system.
High performance
As highlighted in the chart on page 3:
- Primary output: up to approximately 34 l/min at 5 bar
- Secondary output: up to approximately 30 l/min at 5 bar
It therefore guarantees high performance and a plentiful and constant flow of water, ideal for both showers and filling the bathtub.
