We've had a Toto with the bidet seat in our ensuite bath for a dozen years now. Wife loves it, but I can honestly say that in a dozen years I've never even tried it out. Just have zero desire for anything spraying at me down there, thanks.
Downstairs we just have a regular Toto toilet, but this spring my wife talked me into getting a bidet seat for it. Bought a Toto seat, so figured it would fit perfectly on the Toto toilet, just like upstairs, but nope. It fits, but it's awkward and ugly and the seat opening is tiny. Seems like the newer seats are designed to fit any brand of toilet, so they've made some compromises. So now I'm stuck with an awkward toilet with a fancy seat I'll never use.
Really don't want to spend the money, but might have to pay to replace the whole thing with a new integrated one.
Oh, and baby wipes FTW.
