I have a round toilet and the seat fit fine with the range of adjustments available on the mounting bracket. A very straightforward install, clear directions, solidly built and a metal tee for the water connection that gives added security over the plastic ones.

The seat and water nicely toasty with a wide range of temp adjustmeant. Night light a real convenience for those late night runs too. The dryer fan really doesn't do much and I didn't expect it to.
