Bemis TC50TTA Marine Bowl Enameled Wood Toilet Seat with Top-Tite Hinge

That's exactly what the TC50TTA is shaped for. It's a round enameled wood seat built to fit marine bowls, which are a different footprint than a standard residential round bowl. The seat measures 14.5 inches long by 13 inches wide, with a bolt spread of 5.5 inches. Measure your bowl from the center of the mounting holes to the front rim and across the widest point before ordering; if your bowl takes a standard round seat at a 5.5 inch bolt spread but is longer than 14.5 inches, this is the wrong shape for it.

No reaching underneath. The Top-Tite hinge tightens from the top, so the whole install happens standing over the bowl, and the Hex-Tite bolt system takes high torque without the seat working loose afterward. For a maintenance tech working a row of restrooms or a boat head with almost no clearance behind the bowl, that is the difference between a five minute swap and a job on your back with a basin wrench.

The TC50TTA is molded wood with a high gloss enamel finish that resists chipping and scratching, and the seat rides 1.875 inches tall on the bowl. Enameled wood gives you a heavier, more solid seat than plastic and it stays put when someone sits down hard, which is why it holds up in rental and multi-family turnover. Where it differs from a solid plastic seat is chemistry: heavy bleach and harsh cleaners will eventually dull an enamel finish, so a plastic seat is the better call if your janitorial spec calls for aggressive disinfectant.

The hinge and the Hex-Tite bolt system come with the seat, so it mounts to a standard two-hole bowl at 5.5 inch centers with nothing else on the order. What is worth having on the truck is a set of replacement bolt caps and a putty knife or bolt cutter for the old seat, since corroded original bolts are usually what turns a seat swap into a longer job.

White, and yes, both the bumpers and the hinges are color matched to the seat so you don't get a gray or off-white hinge sitting on a white bowl. The hinges themselves are plastic. White is the only color this model is built in, so if you are standardizing a building on one seat, every opening gets the same finish.

Yes, the TC50TTA is US made, and Bemis states it is produced with eco friendly materials and processes. That matters on public and institutional work where domestic sourcing or sustainability criteria sit in the purchasing spec.

Bemis TC50TTA, ordered as part number TC50TTA 000, where the 000 suffix is the white color code. Quote that full string when matching seats across a property so you get the same shape, the same enameled wood body, and the same Top-Tite hinge every time.
