I should also add that the bathroom is too small for a double entrance from both bedroom or common area.

Much is dependent upon the layout of the spaces. A floor plan(s) would be helpful in determining the extent of the concern.

Having lived in a 3/2 for 11 years, fist with 2 people, then with 2 adults and 2 kids and lastfew years with 4 adults and 2 kids before we had to move to maintain sanity, let me ask you a couple questions:

How many people will be living full time?

How many times will you have overnight guests?

How many times do you entertain and are you OK with guests using your master bath?

There is no right or wrong answer, for me personally having a Powderroom is absolutely critical. Is that an option at all? Of course you may not it based on your lifestyle.

We’re in the process of reconfiguring the layout to add this extra bedroom, so I don’t have anything to share right now. I would say we are a young married couple who won’t have kids. We will use the space as a “snug” so we don’t mind the door in either place. I want to know mostly about what most people prefer, as it won’t be a forever home. I want to try to make the best decision for the next family. Adding a power is not an option.

Oops wrong thread!

OP, I would not worry about the next family, who know what they would need. If it's only the two of you, I'd make the decision based on who your guests would be and how often people visit etc.

Since you're not using it as a primary bedroom it doesn't need a connection to the bathroom. But the floorplan will really determine how the entrance affects the rest of the space. An entrance off the kitchen or dining area would be one I'd want to avoid. And a guest can always go to the second floor. It'll work fine.

How did you get to this point in the design?

Mark - I’m not sure I understand your question. We designed a narrow, modern home and the City passed an ordinance in that time that requires our home is wider than what we designed. We have to now add about 12 feet, so we’ve added a bedroom. But we’re working with our CAD designer now go figure out the space.

That gives me the information I was looking for.

If the common area will be used as a 'family room', I would put the door on the common area. Is it possible to plan the layout of the bathroom in a way that if the next owners want to move the door they would have that option?
