House of Rohl GS 1/2″ Thermostatic and Pressure Balance Trim with 3 Functions TGS23

Product Overview Streamlining wall clutter without compromising functionality is a primary objective in contemporary bathroom design. The House of Rohl GS 1/2″ Thermostatic and Pressure Balance Trim with 3 Functions TGS23 offers an integrated solution for controlling complex shower configurations. Engineered with solid brass internals, this control trim combines complete water volume management, multi-outlet switching, and strict temperature maintenance into a single wall plate. By eliminating the need for independent shut-off or additional diverter valves, it creates a clean, uncluttered aesthetic across Canadian walk-in showers and modern wet rooms.

Key Features & Benefits

• Integrated 3-Function Control: The unit operates up to 3 individual shower functions, offering the versatility to run two outlets independently or simultaneously. This setup allows for running a overhead showerhead alone, a handshower unit separately, or both fixtures together for an immersive bathing experience.

• Set-and-Forget Temperature Memory: Advanced internal thermostatic mechanics maintain your preferred water temperature from one use to the next. You never have to manually recalibrate the handle position during every shower, preserving both comfort and energy efficiency.

• Combined Thermostatic and Pressure Balance Protection: By pairing pressure-balancing technology with thermostatic temperature regulation, the trim protects users from sudden pressure drops or unexpected temperature fluctuations when other household water sources are used.

• Built-in Diverter Mechanism: Having the diverter incorporated directly inside the trim plate eliminates extra wall rough-ins and exterior valves, keeping wall tiling visually clean and reducing installation complexity.

• Solid Brass Construction: Built from heavy-duty solid brass, the structure resists wear, corrosion, and daily stress, maintaining long-term mechanical reliability and surface integrity.

Design & Available Finishes Constructed with minimalist geometry and crisp detailing, this valve trim serves as an anchor piece for custom shower systems. It is available in two distinct visual finishes to match broad design preferences:

• Chrome: A bright, mirror-like classic finish that complements traditional and modern spaces alike.

• Black: A bold, matte-style tone that provides sharp contrast against lighter tiles and aligns with modern architectural hardware.

Specifications & Installation Requirements

• Inclusions: Includes the decorative valve trim, internal cartridge, and all required mounting hardware for final assembly.

• Rough-In Valve Requirement: Requires the House of Rohl R23 thermostatic and pressure balance rough-in valve (sold separately).

• Flow Performance: When paired with the required R23 rough-in valve, the system delivers a generous flow rate of 6.3 GPM (24.9 LPM) at 60 PSI, providing ample water volume to power dual fixtures at the same time.

Ideal For This 3-function thermostatic trim is suited for high-end residential renovations and new custom builds where multiple outlets, such as a main rainfall showerhead combined with a secondary handshower slide bar, are controlled from a central point. Its dual-function capability makes it ideal for homeowners seeking a tailored, high-flow shower system.
