Sincerely, Your American Standard Consumer Connection Team. **Q: Will this fit American Standard model 4225A?** A: Hello, The 4225A is your tank number, so it would depend on the bowl you have. If you have a standard, elongated bowl, this seat will work. Thank you, Your Consumer Connections Team **Q: Will this fit on a american standard with 6.0 lpf and 1.6 gpf ?** A: The numbers that you are providing are only the liters and gallons per flush of the toilet. That doesn't indicate what shape of bowl you have. This seat fits on a standard elongated toilet bowl. Sincerely, Your American Standard Consumer Connection Team **Q: What is the length of the seat from the center of the bolt holes to the front edge of the seat?** A: About 18 1/2 inches. This fit all 3 of my toilets. ## Frequently Bought Together - American Standard 5503A00B.020 Slow Elongated Closed Front Toilet Seat, White - 2Pcs Toilet Seat Screws, Steel Toilet Seat Hinge Bolts and Nuts, Heavy Duty Toilet Seat Fastener with Plastic Nuts and Metal Washers, Toilet Hardware Replacement for Top Mount Toilet Seat Hinges --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/284262999-5503a00b-020-transitional-slow-close-toilet-seat-white](https://www.desertcart.jp/products/284262999-5503a00b-020-transitional-slow-close-toilet-seat-white) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-04*
