The Sanagloss version of the Ultramax would work fine for that.
It comes with the SS114 softclose, though any elongated seat will do.
The SS204 if a bit flatter.
Whether you go with E or G doesn't make that much difference.
If you think you need a bit more water, just hold the handle down longer. Done.
The Sanagloss is a nice finish. I try to use those myself when I'm not into trying something new.
Seats. For some, the first time they sit on a seat that has a curve, it may a surprise. I and others prefer them, not everyone does. Because I go back and forth, I find the flat ones annoying. But they still work. They all work.
What I do really like is the slow closing feature. But then I'm a guy, that gets asked to keep the seat down. If you are a guy. You must get the slow close seat, and it should be the elongated one. Don't let anyone talk you into a round seat. That just isn't right for a man.
