House of Rohl Parabola™ 1/2″ Therm & Pressure Balance Trim – TPB23

Product Overview

A streamlined shower design starts with controls that provide both flexibility and a clean appearance. The House of Rohl Parabola™ 1/2″ Therm & Pressure Balance Trim With 3 Functions is a three function shower control designed to manage different shower functions while keeping the wall layout visually uncluttered. Its thermostatic and pressure balance functionality supports a more considered shower experience, while the elegant control design complements refined contemporary bathroom interiors.

Three Function Shower Control

The Parabola™ trim supports up to three functions, giving you the flexibility to configure the shower around how you use it. The controls can operate a showerhead independently, a handshower independently, or the showerhead and handshower together.

This flexibility is particularly useful when planning a shower where different water outlets serve different purposes. Instead of requiring a separate shut-off or diverter valve, the three function configuration helps reduce the number of visible controls needed on the wall. The result is a more streamlined shower arrangement with less visual clutter.

Temperature Memory and Everyday Control

Set it and forget it temperature memory allows the preferred temperature setting to be retained for convenient operation. This feature is useful for everyday shower routines where consistent temperature control is important.

The combination of thermostatic and pressure balance trim provides a dedicated control solution for shower applications requiring both temperature and pressure management. The cartridge is included with the trim, making it an important component of the complete control assembly.

Solid Brass Construction

Solid brass construction gives the Parabola™ shower trim a substantial material foundation while supporting long lasting performance. It also contributes to the refined appearance expected from a carefully specified bathroom fixture.

Available finishes include Chrome and Polished Nickel, allowing the trim to coordinate with different bathroom design schemes and fixture selections.

Installation Requirements

All necessary mounting hardware is included with the trim, and the cartridge is supplied as part of the product.

The House of Rohl® R23 thermostatic and pressure balance rough-in valve must be ordered separately. The R23 rough-in valve supports a flow rate of 6.3 GPM / 24.9 LPM at 60 PSI, providing the required valve foundation for an immersive shower experience.
