How large is your addition? I'm planning a 2 story 240 sq ft addition on the rear of my house to create a master suite upstairs and family/laundry room downstairs. I think option 1 is probably the best out there. Do you really need a 90" vanity? It's really huge. And I would move the bathroom door closer to the closet. Some people like to keep the closet and bath close to each other because they like to go take shower and then walk naked to the closet to get dressed. :) It really depends on your lifestyle. Have you shopped for the tub and the bed? That might change the layout/ design a bit.
