Round toilet seat for everyday use

The Kohler K-4775-0 Brevia Q2 is a white, round-front closed seat made from solid polypropylene. It resists staining, fading, chipping and peeling while an ergonomic contour adds comfort. Quick-Attach hardware allows fast installation using pre-drilled holes and a top-tightening wing nut. Quick-Release lets you remove the seat without tools for thorough cleaning.

Check bowl shape and hinge spacing

Verify that your toilet bowl is round-front rather than elongated so the seat matches the rim contour. Confirm the distance between the mounting holes lines up with the supplied hardware. Ensure the existing bolt holes are intact and free of corrosion so the Quick-Attach wing nuts can grip securely. The seat includes colour-matched plastic hinges; no extra parts are required.

Simple upkeep with no mechanical parts

The polypropylene construction handles regular bathroom humidity and cleaning agents without warping or discolouration. Quick-Release hinges allow the seat to be lifted away for full access to the bowl and hinge area. No moving hydraulic or powered components are present, so there is no operational noise or power draw. Routine wiping keeps the finish looking new.
