House of Rohl 1/2″ Thermostatic & Pressure Balance Rough-in Valve with Up to 3 Functions Unfinished R23-EX

Description

Create a personalized luxury shower experience with the House of Rohl 1/2″ Thermostatic & Pressure Balance Rough-in Valve with Up to 3 Functions (R23-EX). Engineered for premium residential bathrooms, this innovative rough-in valve combines thermostatic and pressure balance technologies into a single compact solution, providing exceptional comfort, safety, and installation efficiency. Designed for use with compatible Perrin & Rowe®, Riobel®, and ROHL® trim collections, it serves as the ideal foundation for sophisticated shower systems in modern Canadian homes.

Unlike traditional shower valve configurations that require separate shut-off and diverter valves, the R23-EX integrates volume control, temperature memory, and multi-function capability into one valve. This streamlined design reduces wall clutter while simplifying plumbing installation, making it an excellent choice for both new construction and bathroom renovations. With fewer components behind the wall, installers can complete projects more efficiently while maintaining a clean, minimalist aesthetic.

The integrated temperature memory feature allows users to set their preferred water temperature once and enjoy consistent comfort every time they shower. By combining thermostatic precision with pressure balance protection, the valve helps maintain stable water temperature even when water demand changes elsewhere in the home, reducing the risk of sudden temperature fluctuations.

Designed for flexibility, this rough-in valve supports up to three shower functions, allowing homeowners to operate two independent outlets or run two functions simultaneously. Whether paired with an overhead showerhead, handshower, or other compatible shower components, the valve provides the versatility needed to create a customized showering experience tailored to individual preferences.

Built from solid brass, the R23-EX delivers outstanding durability, corrosion resistance, and long-term reliability. Its robust construction is designed to withstand years of daily use while maintaining dependable performance behind the wall. The valve also includes practical service features such as an integrated service stop, allowing maintenance without shutting off water to the entire home, and a test cap that enables plumbers to pressure-test installations without exposing the cartridge to potential damage.

With a high flow rate of 6.3 GPM (24.9 LPM) at 60 PSI, this rough-in valve supplies ample water volume for an immersive and satisfying shower experience. The recommended 1/2″ NPT inlet connection ensures compatibility with standard plumbing systems, making installation straightforward for professional contractors.

Compatible with all Perrin & Rowe®, Riobel®, and ROHL® trim kits ending in -23 for shared functionality and -44 for non-shared functionality (sold separately), this rough-in valve provides the flexibility to design a premium shower system that meets your exact needs. Backed by a limited lifetime warranty, the House of Rohl R23-EX offers lasting peace of mind, exceptional engineering, and dependable performance for luxury bathroom projects across Canada.
