House of Rohl GS 1/2″ Therm & Pressure Balance Trim With 5 Functions TGS45

Product Overview Managing complex shower systems often requires installing multiple control valves, creating a busy and cluttered appearance on the shower wall. The House of Rohl GS 1/2″ Thermostatic and Pressure Balance Trim consolidation resolves this challenge by housing extensive control capabilities within a single, refined architectural fixture. Crafted for multi-outlet shower installations, this trim plate allows home renovations to achieve high-capacity performance without sacrificing visual minimalism.

Key Features & Operational Benefits Built around custom usability, the unit features built-in set-it-and-forget-it temperature memory. Once you establish your ideal water temperature, the valve maintains that setting across uses, eliminating the need to readjust controls every time you step into the shower.

The integrated selector mechanism supports up to 5 functions, enabling the operation of three independent outlets, including running two functions simultaneously. Because selector control and temperature regulation exist within one unit, there is no need to plumb in a separate shut-off or diverter valve. This single-piece configuration drastically reduces wall clutter while simplifying behind-the-wall plumbing layouts.

Material & Construction Quality Engineered from solid brass, this valve trim delivers exceptional durability and structural integrity necessary for daily high-pressure water contact. Solid brass construction prevents warping, resists corrosion, and ensures internal components operate smoothly over years of continuous use. The trim includes the required internal valve cartridge out of the box, as well as all necessary mounting hardware to simplify the final installation phase.

System Requirements & Compatibility To achieve full operational capacity, this product must be paired with the House of Rohl R45 thermostatic and pressure balance rough-in valve, which is sold separately. When paired with the R45 rough-in, the system supports a robust flow rate of 6.3 GPM (24.9 LPM) at 60 PSI, delivering consistent, reliable water volume for dynamic multi-head setups such as rainheads, handshowers, and body sprays.

Design & Finish Options Available in classic Chrome and modern Black finishes, the GS collection trim allows homeowners and designers to align their water control hardware with broader interior themes. The clean structural lines integrate seamlessly into high-end master ensuites and luxury family bathrooms across Canada, offering a balanced aesthetic that elevates contemporary tile work.
