Mayfair Caswell Elongated Toilet Seat — Slow-Close Durable Plastic, White

Product description

This seat ships with the slow-close lid and seat, a set of STA-TITE fastening hardware, and installation instructions. The package provides everything needed for a straightforward DIY swap.

The seat is molded from durable plastic designed to resist cracking, chipping, warping and staining under normal household use. The exterior is finished in clean white for broad compatibility with bathroom fixtures and is easy to wipe down; mild cleaners are recommended to maintain the finish.

A Whisper-Close hinge controls the descent of the lid and seat so they close quietly and slowly — a gentle tap is all that’s needed to start the soft close. Note: the slow-close function activates once the seat is installed correctly.

The STA-TITE fastening system secures the seat to the bowl and is engineered to remain tight over time so the seat won’t shift or require frequent retightening. Installation can typically be completed in a few minutes using the provided hardware and instructions.

The seat measures approximately 14.31 inches wide by 19 inches long and is intended to fit standard elongated toilet bowls from common manufacturers such as American Standard, Kohler, and Toto. It is manufactured in Sheboygan Falls, Wisconsin, USA.

Customer support is available for installation questions or warranty concerns. For long-term care, avoid harsh abrasives and strong chemical cleaners to preserve the seat’s finish and hinge performance.

Pros

  • Quiet, slow-close lid prevents slamming
  • STA-TITE mounting stays secure over time
  • Durable molded plastic resists common damage

Cons

  • Lightweight construction may feel thin to some
  • Proper installation required to enable slow-close
  • Verify measurements — fit depends on bowl size

VerdictThis elongated plastic toilet seat combines a quiet, slow-closing lid with a fastening system designed to resist loosening, making it a practical swap for busy bathrooms. It’s lightweight but feels sturdy, installs in minutes with included hardware, and matches most U.S. elongated bowls. Expect a long-lasting finish if cleaned gently; measure your bowl before buying to ensure an ideal fit.

Reviews

  1. Allendale Dan 5/5

    Good value and honest construction

    Installed quickly, will not slam, and feels like a fair value for the quality.

  2. robert raposa 5/5

    Lightweight and affordable option

    Simple to install and the lid closes very slowly. Happy with this inexpensive upgrade.

  3. D. Johnson 5/5

    Fixed a persistent shifting problem

    Bought this for the slow-close and to stop the seat from loosening. My wife often sat sideways and previous seats would loosen; this one stays put and does exactly what we needed.

  4. Vanessa Lee Berlein 2/5

    Wrong size for my toilet

    Not a standard/universal fit for my bowl.

  5. CenturionV 5/5

    Holds up under heavy use and is truly whisper-quiet

    High-quality feel, the slow-close is genuinely quiet — tap it and it will take a long time to close without any sound. It hasn’t loosened despite frequent use by large users.

  6. my 2 cents 5/5

    Took longer than expected but ended up snug

    Removing the old seat was harder than I thought and I had to redo the new one to get the threading right around my bidet. It took time, but once set the seat is snug and a clear upgrade from before.

  7. Scott & Melissa 4/5

    Quiet, comfortable upgrade with a small hinge cover flaw

    Swapped an older seat for this model and it was an easy install. The slow-close works exactly as advertised and the white finish updates the look. After a few weeks one hinge cover won’t stay fully closed — not a deal breaker but could be made to snap in more securely.

  8. Jorge Maravilla 5/5

    Buen producto — recomendable

    Recomendado. Cumple con lo que ofrece.

  9. Jim 3/5

    Dimensions shorter than listed

    The listing said 14 inches across but the seat measured closer to 13 inches. My previous 13-inch seat didn’t reach the bowl edges and risked cracking, but this one is slightly wider on both sides so it rests okay. I’d rate higher if the advertised size were accurate.

  10. Marisa 5/5

    Solid replacement — fits perfectly and quiet for families

    I measured my elongated bowl before ordering and this seat matched perfectly. Installation took around 5–10 minutes using the supplied hardware and instructions. The STA-TITE mounting really holds — no wobble after weeks of use. The plastic wipes clean easily and shows no staining so far. The slow-close feature is great for households with kids.

  11. zehra hassan 2/5

    Doesn’t fit UK bolt spacing

    Bolt spacing is too narrow for U.K. toilets so I couldn’t attach it to my bowl.

  12. Ahmad Yousuf Baqer Al Amiri 1/5

    Missing a part so I couldn’t install

    An essential piece was missing from the package, so I couldn’t attach the seat to my toilet.
