House of Rohl Arca™ 1/2″ Therm & Pressure Balance Trim With 5 Functions TAA45

With five available functions and the ability to operate three independently, the House of Rohl Arca™ 1/2″ Therm & Pressure Balance Trim With 5 Functions gives shower planning greater flexibility without requiring a separate shut-off or diverter valve. Its thoughtful control arrangement keeps the wall visually organized while providing practical command over multiple shower outlets.

Five Function Control

The TAA45 supports up to five functions, with three independent functions available and two functions able to run at the same time. This configuration gives a more adaptable approach to shower control, making it suitable for installations that include multiple water outlets. The control can accommodate a more varied shower routine without relying on a separate diverter control.

Temperature Memory

Set-and-forget temperature memory adds a useful layer of everyday convenience. Once the preferred temperature is established, the control retains that setting for subsequent use. This helps reduce repeated temperature adjustments and makes the shower easier to operate from one use to the next.

Streamlined Shower Wall

A separate shut-off or diverter valve is not required for this trim. Removing the need for additional dedicated controls can help reduce visual clutter and keep the shower wall more cohesive. This is particularly useful when planning a contemporary shower area where the control layout is intended to remain clean and focused.

Solid Brass Construction

Solid brass construction provides the material foundation for durability and long-lasting performance while supporting the refined appearance of the Arca™ collection. For a frequently used bathroom, the substantial construction suits everyday shower operation without compromising the fixture’s considered visual character.

Finish Choices

The trim is available in five finish options: Brushed Gold, Black, Brushed Nickel, Chrome, and Polished Nickel. Having multiple finishes allows the shower control to coordinate with other fixtures and bathroom hardware. Each option offers a different visual direction while retaining the same supplied control configuration.

Installation Components

All necessary mounting hardware is included with the trim, and the cartridge is supplied as part of the trim assembly. The House of Rohl® R45 thermostatic and pressure balance rough-in valve must be ordered separately. When planning a new shower installation or renovation, the required R45 valve should therefore be selected alongside the trim.

The R45 rough-in valve supports a flow rate of 6.3 GPM / 24.9 LPM at 60 PSI, providing the specified flow capability for the compatible shower control system.
