Grohe 19880000 Grohflex Pressure Balance Valve Trim Kit

Product Description

The GROHE 19880000 is a single-function pressure balance valve trim kit designed for shower-only or shower and tub diverter applications. It ships with an integrated control module and features GROHE StarLight chrome finish for long-term corrosion resistance and a polished appearance. The SilkMove cartridge delivers smooth, precise handle operation with consistent temperature and flow control. At 6.1 gallons per minute at 45 psi, the trim provides strong flow performance suited to residential shower systems. Licensed plumbers install this trim as the user-facing component over a separately purchased rough-in valve body.

This trim kit is designed for use with the GrohFlex universal rough-in box, part number 35 026 000, which is sold separately. It fits shower-only configurations or shower and tub setups when paired with a diverter tub spout. An integrated bypass option is included for diverter tub spout applications. Typical installations are found in residential bathrooms where a clean, low-profile trim aesthetic is required alongside reliable pressure balance protection.
