When it comes to choosing a toilet, few can argue that the top priority is completely cleaning the bowl with a single flush. No one wants to have to deal with "leftover" waste either by having to flush again, or by getting out the toilet brush. Standard, single flush toilets, which use 1.6 gallons of water per flush (gpf), get the best reviews for bowl-cleaning performance. However, as we noted in the introduction to this report, they do not meet the High Efficiency Toilet (HET) standards that are required by law in California, Colorado, Georgia and Texas. If water efficiency is a priority for you, or you live in one of those four states, see our discussions of dual-flush toilets and low-flow toilets elsewhere in this report.
Toto is a highly-respected name in the toilet manufacturing world, and few toilets get the raves of the Toto Drake CST744S (Est. $230 and up). Like most standard toilets, the Drake is rated at 1.6 gpf, but gets excellent marks for bowl-cleaning performance thanks to Toto's powerful G-Max flushing system. That power is achieved with an extra-wide, 3-inch flush valve and a 2.125-inch trapway for maximum solid waste removal with every flush.
The CST744S earns a MaP score of 1,000, the highest possible from that independent tester. That means it removes 1,000 grams of solid waste or more with a single flush. In another professional test, the Toto Drake earns a rating of Excellent both for removing solid waste and for complete bowl cleaning. Owners agree, saying this toilet leaves no mess behind. In spite of its flushing power, professional testing shows that the CST744S flushes quietly, and users largely agree that there are no noise issues with the Toto Drake.
Another option at about the same price point, the Toto Drake CST743S (Est. $240 and up), has a round, rather than elongated bowl, something that some people prefer. It's also about a half-inch taller than the CST744SG-01, 15 inches compared to 14.6. Although neither model is ADA-compliant, the CST743S may be more comfortable for families of taller stature. It also uses Toto's G-Max flushing system.
The Kohler K-3754-0 Kelston Comfort Height (Est. $280 and up) features a 16.5-inch bowl height that is not only more comfortable for taller users, but is also ADA-compliant when installed per the applicable guidelines. Beyond that, the Kelston gets Excellent scores for solid waste removal in one professional test; a Very Good for noise and bowl cleaning. Owners say this toilet is stylish and performs very well in cleaning the bowl with one flush. It has an elongated bowl and comes in seven different colors.
One-piece toilets tend to be pricier than two-piece toilets, they're also heavier and might be more difficult to install. However, they're very popular because of their sleek looks and because they have fewer nooks and crannies, which makes them easier to clean. The American Standard Fairfield One-Piece Toilet (Est. $290 and up) earns raves from owners for its sleek, modern look, as well as for how simple it is to clean. It has an elongated bowl and, unlike most toilets, includes a seat, although a few say the seat seems cheap. The 15.5-inch bowl height is not ADA compliant.
For those who have oddly-shaped bathrooms or where space is at a premium, the American Standard Cadet 3 (Est. $315 and up) may fit the bill. It's basically just a regular toilet with a triangular tank, but owners adore the way it looks in their bathroom -- many say it's become quite a conversation piece simply because a corner toilet is so unusual. Beyond aesthetics, reviewers say this toilet is easy to install and has a strong enough flush that it cleans the bowl very well. It's not WaterSense certified, which means it uses a full 1.6 gpf, so doesn't meet low flow regulations in place in California, Colorado, Georgia or Texas.
