Ice Gray is going to be tough.
Toto was making some gray toilets, some in round front, 26-1/2" long.
You may find something like a Drake or Ultramax in gray.
Consumer Reports like the Cimarron (four times) and the Gerber Ultraflush (five times) in their August 2009 report.
Anyone with any intelligence would have only rated the Cimarron once, and the Gerber Ultraflush once.
Consumer Reports made up nine reports from two bowls.
Makes for fluffy reading.
I don't care much for those toilets, selling them when I have to, except for CR's top choice in a dual flush, the Gerber DF-21-318 which has been a real dog. I won't sell that one.
Kohler Cimarron, poor bowl wash, clogs more then others in it's class.
A good percentage of returns for defects.
The class five flapper has been leaking, so now the class six canister flush stiffens up the rubber, but now the chain hangs up every so often.
Gerber Ultraflush, startling flush, very small footprint rarely covers a previous installation. Looks like it belongs in a gas station mens room.
The dual flush option fails very quickly, expect to replace the tank at least yearly.
I have the best luck with the Toto products.
But I don't think Toto is bothering to send any checks CR's way.
They're selling everything they can produce.
