I was just looking at those samples the other day. They are very similar but colonial white is just a bit brighter. I would consider it a bright, pure white. Cotton white is the standard color most places stock so that is what you see in the showroom models. The sales rep was trying to convince me that no one ever orders anything besides cotton white but with white wainscoting behind the toilet I want to make sure I get the right white. Plus they are the same price so there is no reason to not the color you want! That's interesting to hear about matching the Kohler products. I can't see them side by side because any showroom that carries Kohler products isn't able to sell Toto products. So I guess I need to check out the sample colors to compare.

For what it's worth, this topic is timeless. Toto Drake is the model. They have short and tall, oval and round. Beyond that there are accessories for it. The best one has the features you want. I used to travel and work from hotels 5 days a week. At one time the hotel I was in was brand new with Toto Drake toilets. I liked them so much I ordered one for my house from a local plumbing supply house. When I went to pick it up they asked if I wanted to see the new American Standard Cadet III. I really didn't want to, but they had a demonstrator set up filled with golf balls. I tried it and changed my mind. One of the features I liked about the Drake was the antifungal and bacterial glaze. The Cadet III used the same glaze. They had rolled the Drake out to my car and I called them back in to exchange for the cheaper toilet. At the time the Drake was $409 and the Cadet III was $122. Since then I have bought 6 more Cadet III models for condos and houses we've moved to. It's the first thing I change. Until this house we moved into a year ago. It has American Standard Estate toilets. I'd never seen one, and after looking it up I knew why. $500 is way more than I would spend on a toilet. It has all the same features as the Cadet III plus nicer styling and a different flush wash through the bowl. Toto reinvented the low flush toilet in the late 2000s, but all the American manufacturers caught on quickly. They caught on so quickly that virtually everyone made a better quality toilet than Toto. I'm not certain what has changed since then, but the Totos are all up to the same quality standards as the rest. If you really want to pay twice as much to have a Toto, that's your business.

dianne47: "Toto is the best toilet brand, hands down." Toto designs and makes excellent toilets; we purchased one (Vespin II, the skirted version of the Drake II) ourselves when we remodeled one of our bathrooms a little over a year ago, and it is the best toilet we ever have had in a home. And Toto has been in the North American marketplace for some time, so a lot of Americans have heard of and owned and used Totos. But Inax, Toto's major rival in Japan, designs and makes toilets that are every bit as good as Toto toilets, and some would argue that some Inax models are better than their Toto counterparts. Inax (which got its start early in the 20th century with an American connection when Frank Lloyd Wright wanted a custom specialty tile made for a major commission for a building in Japan) only recently has begun to establish a North American toehold, so you will not see as much discussion of Inax as of Toto; but those who have bought and used Inax toilets are just as enthusiastic as those who sing praises of their Totos. (Both Toto and Inax use American-sourced internals: flapper valves, etc., in their North American models, so parts availability is not a problem with either.) No doubt that janesylvia would be happy with a Toto; but she would be every bit as happy, maybe even happier, with, say, an Inax Dover one-piece or the less expensive two-piece Inax Rio Grande, which can be had in a dual flush configuration.

artemis78: "The Wellworth has a better MaP rating (1000+ vs. 500-800 for the Totos) so I'm trying to figure out how meaningful that really is." Not meaningful at all at that level. The average dump is around 250-300 grams; anything above 400-500 is more than adequate. It is a Good Thing to have an objective standard to compare flushing performance, but there are two cautions that must accompany MaP numbers. The first is that, above a certain level, it makes zero difference. A toilet with a 300 MaP rating will flush 250 grams every bit as well as a toilet with a 1,000 MaP rating; once the stuff is flushed, it is flushed; the 1,000 MaP rated toilet cannot flush it four times. Does a car with a speedometer that goes up to 140 mph get around town any quicker than one with a speedometer that goes only to 100 mph? The second caution is that a MaP rating measures only one aspect of flushing performance: how many condoms of standard diameter and length stuffed with a specific miso paste (not all miso is alike) will be flushed in one action. But not all waste is identical; there will be the occasional hard turd, or the outsize diameter turd, or the extra long turd; the MaP test does not test how a toilet deals with waste of unusual sizes or consistency. If you have a teenager who uses much too much toilet paper, especially "Ultra" thick toilet paper, you may find to your dismay that a toilet rated highly for MaP does not handle paper clogging as well as a lower-MaP toilet. MaP does not deal with bowl streaking issues, either: some high-MaP-rated toilets all but demand that you keep a brush handy by the toilet to wipe down the bowl after a flush. The MaP test does not test noise, which may be an issue in a powder room just off the living room where guests gather or a bathroom adjacent to the nursery where the baby sleeps. We installed a Toto Vespin II, the skirted version of the Drake II, at the first of the year. After about 300 days of daily repeated use, we are delighted with it. It flushes everything the first time, reasonably quietly, and the Sanagloss finish on the inside of the bowl keeps streaking to a minimum. Nothing specifically negative to say about the Wellworth; but for the best overall performance, your choices really are between Toto and Inax (Inax is the BMW to Toto's Mercedes), which from a performance standpoint are far and away the top two brands of toilets in the world.
