American Standard 5503B00B.020 – Frequently Asked Questions

1) Does the American Standard 5503B00B slow close seat come with mounting hardware, or do I need to buy bolts separately?
Top and bottom mounting hardware is included, so no separate bolt kit is needed. The existing seat comes off and this one goes onto the same two bolt holes in the bowl.
2) Is the American Standard 5503B00B toilet seat durable enough for a rental unit or high traffic bathroom?
It is molded polypropylene plastic, wipe clean, and rated by the manufacturer for residential use. For heavy commercial traffic (schools, stadiums, public restrooms) a commercial grade open front seat is the better call. The slow close hinge is also the part that wears in abusive settings, so in a rental with rough tenants a plain solid plastic seat is less to go wrong.
3) What is the exact part number to order the American Standard transitional slow close round front toilet seat in white?
The manufacturer part number is 5503B00B.020, with .020 being American Standard's suffix for White. Quote that number if you are standardizing seats across a property so every reorder lands on the same seat and hinge.
4) How much does the American Standard 5503B00B round toilet seat weigh and how big is the shipping carton?
The seat weighs 3.303 lb and the packed dimensions are 18.11 x 14.188 x 2.563 inches. Useful if you are ordering a stack of them for a multi unit turn and need to know what fits on the truck or in a storage closet.
