Bemis 1200E4 Affinity Elongated Plastic Toilet Seat with STA-TITE Seat Fastening System, Easy-Clean, Whisper-Close, Precision Seat Fit Adjustable Hinge and Super Grip Bumpers

The 1200E4 Affinity is an elongated seat that fits most manufacturers' elongated bowls. The mounting holes work on the standard 5-1/2 inch bolt spread, and the seat itself measures 18.563 inches long by 14 inches wide. It also has front-to-back adjustability at the hinge, so you can shift the seat to line up with the bowl rim instead of living with an overhang. Measure your bowl from the center of the two mounting bolt holes to the front edge of the rim; an elongated bowl runs about 18-1/2 inches and a round bowl about 16-1/2, and this seat is the elongated shape only.

The 1200E4 uses the STA-TITE fastening system, which Bemis states will never loosen. That is the whole point of the design for high-traffic restrooms: a conventional plastic wing nut backs off from constant seat movement and turns into a callback. It also carries Super Grip bumpers that keep the seat from sliding around on the china, which is what usually starts the fastener working loose in the first place.

Mounting bolts sit on 5-1/2 inch centers, which is the standard two-bolt spacing on virtually every residential and commercial water closet in North America. If your existing seat bolts drop straight through two holes at that spacing, the 1200E4 mounts in the same prep with no drilling.

Four colors: White, Bone, Biscuit, and Almond. The color is molded into the plastic rather than sprayed on, so chips and wear do not expose a different color underneath. If you are matching a fleet of older units, Bone, Biscuit, and Almond are three distinct off-whites, so pull the color code off the china rather than eyeballing it.

Yes. The Easy Clean hinge lets the seat lift off without tools so staff can get at the hinge area and the china underneath, then drop it back on. For hospitality, healthcare, and multi-family turns, that is the difference between cleaning around the hinge and cleaning under it.

Both the ring and the cover are Whisper Close, so neither slams. Both halves close slowly on their own. In apartments, dorms, and hotels this is a noise complaint and a pinched-finger issue solved at the seat rather than at the door.

Solid plastic, with plastic hinges, and the color molded through the material. Plastic resists chips and stains and takes disinfectant better than a molded wood seat, which is why it is the usual pick for commercial restrooms and rental turns. Molded wood is heavier and feels more solid underfoot but the finish is a surface coating that can chip through to the substrate.

It does. The Precision Seat Fit hinge gives front-to-back adjustment, so once the bolts are through the china you can slide the seat forward or back to center it on the rim before tightening. That takes care of the common gripe where a seat mounts straight but sits too far back or overhangs the front.

The seat stands 2.25 inches in height. Worth checking if you have a tank lid or a flushometer that sits close behind the bowl, or if you are working to a finished seat height on an accessible fixture, because the seat thickness stacks on top of whatever the rim height already is.

Designed and assembled in the USA, with country of origin listed as US. That matters on government, education, and institutional jobs where domestic sourcing is a line item on the submittal.
