ctkathy: "m staying away from the Aquia. Any experience with matching up a washlet with a Toto? "

We have a Toto Vespin II, and, on it, an Inax Clessence. They match.

Because of our family's Japanese roots and connections, we did not seriously consider any brands of "shower" toilet seats other than Toto and Inax. (Washlet is a registered trademark of Toto, so any non-Toto seat cannot be a Washlet.)

Inax invented the category of toilet seats that perform, and in Japan, Inax and Toto vie for dominance in that category the way that Chevy and Ford fight over the pick-up market in the United States. The role that second-tier players like Dodge and Toyota and Nissan play in the pick-up wars here is taken by Toshiba and Panasonic in the toilet seat wars in Japan, No other players come close.

Do you know who makes the Bio Bidet? I don't. Apparently, it is an American brand, applied to a seat made in Asia.

Toto seats fit Inax toilets and Inax seats fit Toto toilets. You can mix and match with confidence. We prefer the two-wand design of the Inax seats to the one-wand design of the Toto seats.

I wasn't going to do the Toto washlet because reviews made me think I wouldn't like the spray pattern. I could consider the Inax toilet and bidet seat but not many choice of toilets. I think I would prefer choosing a Toto toilet and an Inax bidet seat. Which Inax bidet seat?
