I have bought 4 American Standard toilets in the last few months from two different stores. All of them have been Grade A (flawless) and work perfectly. The ceramic is perfect, no flaws in the glaze, no repairs, no cracks, no rocking and they sit perfectly level. They are a very high quality product. I am a very picky person and will not accept anything new which has the slightest flaw.
I checked into Toto before buying American Standard and found that they were too expensive and did not perform as well. I bought three cadet 3 1.28 gallon flush and one Champion 4 1.6 gallon flush. The Champion 4 performs so well that I have adjusted the water level as low as it will go to conserve water. It has never clogged and the bowl has never required cleaning.
The three Cadet 3s are one piece toilets and are absolutely beautiful. I will post some pictures when I get around to it. I bought the Watersense version since there is currently a $100 each rebate from my water company. They perform extremely well - no clogs, and no cleaning necessary. The bowl wash is very effective and the everclean surface stays spotless.
I can honestly say that these toilets perform better in every way than the three 3.6 gallon and one 5 gallon flush toilets they replaced.
All four of the toilets I bought have MAP ratings of 1000. I am not aware of any Toto toilet that has a MAP rating of 1000. I think Toto could learn a few things from American Standard.
I am not going to criticize Toto - they make a great product, but I personally prefer the performance, price and quality combination that I got. I have two more toilets to buy and they most certainly will be American Standard.
