Description

Create a premium custom shower system with the House of Rohl 1/2″ Thermostatic & Pressure Balance Rough-In Valve R23, engineered to deliver exceptional comfort, reliable performance, and simplified installation. Designed for modern luxury bathrooms, this advanced rough-in valve combines thermostatic and pressure balance technologies into a single solution, allowing homeowners and professional installers to achieve a clean, uncluttered shower design without sacrificing functionality.

Unlike traditional shower valve configurations that require separate shut-off and diverter valves, the R23 integrates volume control, temperature memory, and support for up to three shower functions within one compact valve body. This innovative design reduces wall clutter, streamlines plumbing requirements, and creates a refined aesthetic that perfectly complements premium bathroom renovations.

The built-in temperature memory feature allows users to set their preferred water temperature once and enjoy consistent comfort with every shower. By maintaining stable water temperature despite fluctuations in household water pressure, the valve enhances both comfort and safety for the entire family.

Supporting up to three shower functions, the R23 offers exceptional flexibility for custom shower layouts. Operate a showerhead or handshower independently, or run both simultaneously for a more immersive shower experience. With a high flow rate of 6.3 GPM (24.9 LPM) at 60 PSI, the valve delivers generous water volume to support luxurious multi-function shower systems.

Built from solid brass, the valve offers outstanding durability, corrosion resistance, and long-lasting reliability, making it an excellent investment for residential and high-end bathroom projects. Service and maintenance are also simplified thanks to the integrated service stops, allowing the valve to be serviced without shutting off water to the entire home. The included test cap enables plumbers to pressure-test plumbing connections before installing the cartridge, helping prevent accidental damage during construction.

The R23 features a recommended 1/2″ NPT inlet connection and is compatible with Perrin & Rowe®, Riobel®, and ROHL® trim sets ending in -23 for shared functionality and -44 for non-shared functionality (trim kits sold separately). This versatility makes it an ideal foundation for a wide range of luxury shower configurations.

Whether you’re designing a spa-inspired ensuite, upgrading a master bathroom, or completing a premium residential renovation, the House of Rohl R23 Rough-In Valve delivers dependable performance, advanced water control, and installation efficiency. Backed by a limited lifetime warranty, it offers Canadian homeowners and professional contractors confidence in both quality and long-term durability for years of exceptional shower performance.
