Has anyone installed a toilet with a larger bowl that fits in the existing location without a lot of modifications.

I personally haven't, but there IS plenty of room there.  The PHII comes with both small and household size bowls.  If you don't have a PHII, get one.

Hi,

I did change my toilet this spring with the standard house size bowl.
We had the micro, small round size before, and is a great improvement.

The new one fitted in the same mounting hole on the floor.
Fit nicely in the head space.
The base is the same size, just the bowl is different.

This was on a mark I boat
And the change was made with the same manufacturer
