Toto is going to be the end of me! Finally narrowed things down to the toilet I want and the Washlet I want - both are Washlet+ so should be a breeze, right? Well turns out for the recent S500/550e series they moved from T20 to T40, aka the hole is now slightly lower than it used to be. Of course the toilet I chose is T20.
Does anyone with experience know if it would be possible to install the newer washlets on the older T20 toilets?

Apologies for using photos from the forum, but here is the older T20 setup:

And this is T40:

If it matters, the toilet I was looking at was the Ultramax II CST604CEFGT20 - not Dynamax but regular Hurricane flush, 17 3/4 tall and a large water spot.
Hey, wait a minute.

This is awkward, but...
