Bemis 1400TTA Elongated Enameled Wood Toilet Seat with Top-Tite Hinge

Measure your bowl from the center of the two seat bolt holes at the back straight forward to the front edge of the rim. About 18-1/2 inches means elongated, about 16-1/2 inches means round. The Bemis 1400TTA is the elongated version, with a seat length of 18.75 inches and a width of 14.188 inches. Bolt hole spacing is 5.5 inches on both shapes, so the holes lining up does not confirm you have the right shape. Only the front-to-back measurement does.

Top-Tite means you tighten the seat from above the bowl instead of reaching underneath to hold a nut. That is the whole point of the hinge on the 1400TTA, and it matters most on a wall-hung or tight-clearance fixture, or in a bathroom where the tank and bowl leave no room to get a hand behind the china. For maintenance staff working a building full of units, it also means retightening a loose seat is a top-side job with no trip under the rim. The hinge itself is plastic, color matched to the seat.

Enameled wood is the heavier, more rigid option compared with molded plastic, which is why it holds up in rental and multi-family turnover work. The 1400TTA is a molded wood core with a high-gloss enamel finish, and the seat measures 1.75 inches tall, so it sits solid on the bowl rather than flexing under load. Where it gives ground is chemical exposure: a high-gloss enamel surface takes daily bleach or abrasive scrub cycles less well than plastic. For a heavy-traffic public restroom cleaned aggressively, a plastic seat is the better call. For apartments, hotels, and light commercial, this is the standard spec.

White only, ordered as MPN 1400TTA 000. The bumpers and hinges are color matched to the seat, so a white bowl gets a uniform look with no contrasting hardware at the back. If you are standardizing a building on one seat, this is the single-color version, which keeps the storeroom simple.

Mounting hardware comes with the seat. The Top-Tite hinge assembly, the bolts, and the color-matched bumpers are all part of the 1400TTA, so nothing else is required to hang it on a standard two-hole elongated bowl at 5.5 inch bolt spread. Bemis publishes an installation guide for it as well, which is worth pulling if your crew has not set a top-mount hinge before.

Yes, country of origin is the United States, and Bemis calls out eco-friendly materials and processes in its manufacture. For institutional and government procurement working under domestic sourcing preferences, that is the relevant line on this seat.
