I have the matching Kohler, installed 3 yrs ago. It's in the guest bath so it doesn't get a lot of use but I don't have a single complaint about it, either.

I've been reading the Toto post. Seems that the owners of two-piece Totos have fewer complaints than the one piece. Could be a coincidence or could be the way they're designed.

I chose the Toto Guinevere to go with the Memoirs Stately pedestal. I thought they had a similar look, and I really wanted Toto flush quality. But I haven't installed them yet, so I'll have to wait and see if they look as good and function as well as I hope.

Riverspots . . . our Kohler toilet in our guest bath stops up a couple of times a week. This is why we're replacing it with the Toto. Hopefully we'll have better luck!

I love the Porcher lutezia sink but it is too big for my space. I am going with the duravit 1930 series, which has a similar look. Either one goes with the toto promenade as I checked them out in person. I'm using the lutezia toilet instead of the toto though, as I have one already and like the look of it. I've had it for 4 years and have had no problem.
