That looks very similar to the Great John Toilet whose company website is no longer up.
I assume it is the same product with a new name.
While the toilet is huge and has a massive foundation and seat for supporting those huge cheeks...
When you look into the bowl it all narrows down to a 1.6 GPF toilet which by law is all that can be sold.
I've never installed one but have seen them in the supply house showroom.
