Rated 4.6 out of 5 by 265 reviewers.
Rated 5.0 out of 5.0 by Overall this was a good purchase, somewhat expensive. The store did have a nice selection of toilets to choose fro,. I was surprised that colors almost double the cost of these toilets but that is the manufactures problem not Home Depots. Installation was relatively easy but one piece toilets and more difficult to install because of their weight. It is almost a two man job. The flushing function works very well I don't believe we have needed a double flush yet. Therefore water savings should be significant. June 30, 2015
Rated 5.0 out of 5.0 by Great Toilet Beautiful toilet. Really like the low flush water conservation even though it takes getting used to the short flush time. Has great power in the flush. Didn't like having to pay and extra $100 just to get the Biscuit color vs white. May 1, 2015
Rated 3.0 out of 5.0 by just got it. Toilet seems to be good.have not had it long enough to know if it will hold up. July 1, 2015
Rated 5.0 out of 5.0 by great flush I went to local store to buy this toilet , based on needs. I was told that no colors other than white were stocked. I ordered it online, picked up at store 5 days later, Installation was easy, used a new wax ring,(not supplied), The flush system is different than most toilets that I have encountered, but works GREAT! The elongated bowl is slighted shorter than others, fitting a smaller area. December 12, 2014
Rated 5.0 out of 5.0 by A royal flush Somehow this toilet uses only about 1.3 gallons per flush and yet flushes much better than our old 1.6 gallon Am. Standard toilet. Plus it's a lot quieter and fills more quickly. The higher seat height we got also makes it much more comfortable and easier to get up from, especially if you are an older person. I have seen the Santa Rosa model used in some other places, like better hotels and inns, so know it must be pretty reliable. February 2, 2013
Rated 4.0 out of 5.0 by Santa Rosa One piece, so it is heavy. Flange bolts are not snap off type (I had snap off type and used them). Hard for this senior citizen to place on flange because could not see bolt holes from above while straddling the toilet (weight of toilet made leaning to side to look a balance problem for me) . Flush is fast, quiet, and efficient. No clogs so far. Seat height a bit higher than other comfort height toilets, so my wife's feet don't fully reach the floor. Not a problem with our comfort height Toto. Only a half inch or so difference. Bought white in store for 36% less. Not a problem attaching standard seat or one with slow close feature (Installed 2 toilets). The handle rattles a bit if let go of suddenly. December 14, 2013
