The GERBER d990558bb is a pressure balance shower trim kit from the Parma Collection, designed for use with a compatible pressure balance valve body in residential shower applications. The trim includes a 5-function hand shower mounted on a slide bar, delivering a flow rate of 1.75 gallons per minute. The brushed bronze finish suits a range of bath aesthetics. This trim kit is installed by licensed plumbers during new construction or remodel work and does not include the valve body.
The d990558bb is intended for residential shower installations where a hand shower with adjustable slide bar is required. The 5 spray functions give end users control over spray pattern selection. The pressure balance design helps maintain consistent water temperature when other fixtures draw flow elsewhere in the system, a common code requirement in residential shower applications.
Designed as an OEM-style trim kit for use with a compatible Parma Collection pressure balance valve body. No specific valve body model numbers were provided in the product data. Confirm valve body compatibility before ordering.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply to the shower valve before beginning trim installation. The valve body must be installed separately and roughed in before the trim kit can be applied. Do not overtighten trim components, as this may damage the finish or the underlying valve cartridge.
