American Standard t420432.002 Portsmouth Shower Diverter

Product Description

The AMERICAN STANDARD t420432.002 is a shower diverter trim kit in the Portsmouth series, finished in polished chrome. This trim-only component controls the flow of water between a tub spout and showerhead in a bathtub-shower combination setup. It mounts over a separate rough-in valve, which must be purchased independently. The polished chrome finish offers a clean, reflective appearance suited to traditional bathroom aesthetics. Licensed plumbers typically handle this installation as part of a complete shower valve trim-out on new construction or remodel projects.

The t420432.002 is designed for bathtub-shower combination applications in residential bathrooms. It is part of the Portsmouth series, which carries a classic design profile. Because the rough-in valve is sold separately, this diverter trim is appropriate for both new installations and trim replacements on compatible rough valve bodies. A plumber would typically select this trim after the valve rough-in is already set in the wall.

Key Features

• Polished chrome finish for a clean, traditional appearance
• Part of the Portsmouth series for coordinated fixture matching
• Trim-only design — rough-in valve sold separately
• Functions as a tub-to-shower diverter in combination bath-shower systems

Compatibility

Designed as an OEM-style shower diverter trim for use with a compatible AMERICAN STANDARD Portsmouth series rough-in valve body, sold separately. Consult the rough valve documentation to confirm trim compatibility before ordering.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply to the valve before beginning trim installation. Do not over-tighten trim components onto the valve body, as this may damage the cartridge or seat. Verify the rough-in valve is fully set and pressure-tested before attaching the trim kit.
