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.

Thanks for the reply. We had already looked at the spec sheets for the two, and checked all over the Toto website and other places to see if they really are the same bowls. I asked over on plumbing too, and someone there very nicely posted a Toto product bulletin that answered the question perfectly: they are interchangeable.

I looked online at them last night after reading the other thread and the only one I found that was ada with sanagloss was the Drake. I wanted a skirted one but didn't find one w/sanagloss tho. and i think about 400.00 would be my limit on a toilet - lol! oh, i also would need the sedona beige color. that might have limited me too. anyone find the 1.28 gpf a problem? I did check the Terry Love site.

We have 2 Toto Drakes and are getting 2 more - we LOVE LOVE them. They are the best! They are powerful with low water usage. I can't recommend them enough. We're impressed enough with the toilets we are getting Toto faucets for our bath remodel.
