I came to this forum during a google search on changing a part on my Cimarron toilet. I saw quite a few posts on the toilet forum touting Toto and thumbing down the Cimarron, so I thought I'd register to give my two cents.
We've had our two Cimarrons for a few years now. Both installed within months of each other. The date stamped on the inside of the tank of the toilet most used is 3/24/10. Both are round bowls, chair height.
Both replaced Kohler Wellworths and with the Wellworths we had to make sure a plunger was nearby. Since installing these two Cimarron's, we've never had to plunge either one. (Just fact-checked this with hubby!)
As far as quality of flush-cleaning, we may need to swish with the toilet brush on occasion after certain types of solid waste flushes. Is that a deal breaker for us? No. It's not a big deal.
We had considered Toto, although the price seemed a bit steep. When my neighbor shared they had a Cimarron and were pleased, we decided to go with the same and have had no regrets.
We nearly always go for quality with our purchases, believing you get what you pay for, thus spending more upfront is well worth it. For the most part that mantra has held true. And I believe it has for the Cimarron.
