There is USUALLY a separate
shower stall in the owner's
cabin, but, most Privileges are owner-specified from new so it is possible the one you are looking at doesn't have one.
Normal spec would be two shower/heads mid-ships, owner's version has sitting/dressing area port fwd
hull, queen-size fwd facing berth on the bridgedeck and
head with large separate shower enclosure fwd of the
head in the stbd hull
