American Standard 5503B.00B.020 Round Toilet Seat

Product Description

The AMERICAN STANDARD 5503B.00B.020 is a slow-close round toilet seat designed for residential and light commercial plumbing applications. The slow-close hinge mechanism prevents the seat and lid from slamming, reducing hardware wear and noise during daily use. This seat is round in shape, making it a direct-fit replacement for standard round-bowl toilets. Installation is handled by a licensed plumber or experienced DIYer during routine fixture service or remodel work.

This seat is suited for residential bathrooms and light commercial restrooms where a round-bowl toilet is installed. It serves as a replacement unit when an existing seat is damaged, worn, or being upgraded as part of a fixture refresh. The round bowl configuration is common in smaller bathrooms and older construction where elongated bowls were not standard.

Key Features

• Slow-close hinge prevents seat and lid from slamming shut
• Round seat shape fits standard round-bowl toilet configurations
• Single-unit selling format for straightforward replacement ordering

Compatibility

Designed as an OEM-style replacement for standard round-bowl toilets requiring a slow-close seat.

Installation Notes

Toilet seat replacement requires no special trade license but is commonly performed by plumbers during fixture service calls. Shut off the water supply and flush the tank before beginning work to allow a dry, clean working environment. Remove the existing seat by unscrewing the hinge bolts from beneath the bowl, then align the new seat hinge posts with the mounting holes and secure per manufacturer instructions. Verify the seat sits flush and the slow-close mechanism operates freely before returning the fixture to service.
