Tub & Shower Faucet for ADA-Compliant Bathrooms
The Kingston Brass GKB531L is a single-handle tub and shower faucet finished in polished chrome. It includes a pressure-balanced valve that maintains constant temperature despite supply fluctuations. The integrated diverter switches flow between the tub spout and the single-function shower head. This unit suits residential and commercial projects requiring ADA compliance.
Thermostatic Stability With Standard Flow
The pressure-balanced valve reacts to changes in hot or cold supply lines to keep the output temperature steady during use. The shower head delivers a fixed 2.5 GPM flow rate through a single spray pattern. One lever handle controls both volume and temperature without the noise of mechanical cartridges cycling. No additional flow-restriction data is provided.
Complete Trim With Included Valve
The package supplies the valve body, so rough-in does not require a separate purchase. The back plate spans 6.75 inches to cover standard rough openings. The shower arm reaches 8.125 inches from the wall, and the tub spout extends 5 inches over the bath. The single-hole lever handle leaves the surrounding deck free for other accessories.

Questions about this item
How do I install the GKB531L tub and shower faucet, and what step is commonly missed?
The pressure-balanced valve must be installed inside the wall and connected to hot and cold supply lines; the step often missed is securing the valve depth so the finished trim sits flush with the wall surface.
What maintenance will the single-function shower head and diverter need later?
Periodically remove the shower head and soak it in vinegar to clear mineral deposits from the 2.5 GPM flow restrictor; lubricate the diverter mechanism if switching between tub spout and shower becomes stiff.
What limit appears first during a long shower with the pressure-balanced valve?
The valve maintains temperature within a few degrees, but the 2.5 GPM flow rate is the fixed limit — extended high-demand use cannot exceed that output.
