Rated 4.4 out of 5 by 150 reviewers.
Rated 5 out of 5 by Went in easy. Flushes like a champ. Family thinks it's the best toilet in the house! Great footprint. Comfortable height. Excellent power flush. Quiet, fast fill. Very easy install. Only one gasket to replace when it's really old, where the tank mates the bowl. The bolts don't touch water so no stupid triangle gasket adding three potential points of failure. Water in bowl has proper placement - not too high so no wet toilet paper or worse - hands or gems. Not too low to avoid dry bowl skid marks. I find no reason to spend more for a 2-piece toilet. You won't beat the flush performance. August 1, 2013
Rated 5 out of 5 by Great Choice Easily installed two -- had first one shipped, small enough box to get second one at Home Depot as it fit back seat of car -- and no problems, two years ago. Excellently designed except for too flexible lid. Flushes quickly, quietly, completely. April 24, 2014
Rated 4 out of 5 by Works Fine Not sure really how to be animated about a toilet, but, here goes,, it was sent to my home, arrived fine, installation went fine, you do need to purchase the wax ring, it is NOT included. Toilet works fine. Its a good toilet, it does what it should and looks fine. October 15, 2014
Rated 5 out of 5 by Great update. Should have updated before now. More comfortable height and shape. Great flush design. Only need to flush once for sure. Had new fixture professionally installed. Removal and replacement took exactly one hour. Plumber took old fixture and box with him. Purchased an elongated, good quality, slow close seat in store. Make a great combo and good investment. One way to beat the city water bills that keep increasing! July 24, 2012
Rated 4 out of 5 by So far so good Nice design for our remodeled master bath. The elongated shape is the way to go nowadays. These toilets ship in two boxes - the bowl and the tank. The bowl itself is relatively heavy but I managed well enough on my own. The tank bolts do not go through the tank itself but intead latch onto a black underside bracket - so less leak worries in the future. Toilet flush on max water isn't what I'm use to on the older models but it does the job. Easy to adjust water level without tools. Relatively quiet overall function. Wax ring, floor bolts and seat are NOT included. The white bowl floor caps come in the tank portion of the order. The bowl box features just the bowl itself. May 12, 2011
