I like kohler's wellworth toilet. I agree the cimarron doesn't have a good bowl wash, though they seem not to have clogging problems.
I hate repairing any faucet or shower valve... It's always a pita. I mostly just won't do it anymore... call someone who likes that work, I don't do it, I do drains.
I have mixed feelings about kohler's tub drains, the ones with the funky linkage and the springy thingy to actuate it. They work nicely, and are very adjustable, but the design is such that anyone can pull the stopper out, then either lose bits of it (which are difficult to get, expensive, and a long time coming from kohler) or put it back in wrong and step on it to force it back in and get it wedged in the spring.
