I would switch the toilet to the shower location and enclose it with a door. This would be ideal as that way you have more room now to have a large shower where the tub is located. I would also do my best to relocate the attic access from the hall outside the powder room to somewhere else, such as in walk-in closet.

Thanks, that's just what we were thinking. We tried putting the (double) vanity on the outside wall to add a window (between the mirrors and have a lower lever makeup table) back to the room which moved the shower to the inside wall. I would love a walk in shower(for wheelchair access) with a tiled floor/drain and no shower pan, we found some river rock tile to use for the floor. I put the shower in to walk around the wall to get in for privacy--just saw a commercial for a rain shower head to eliminate water splash. Will try to attach the revised drawing (or find one of my kids to do it for me!)
Any thoughts?

Here's the most recent direction we have moved in. I know we have further configurations and size changes to do. But are hoping for some design suggestions. It's amazing how quick you can get tunnelvision to what's already on the plan.
To respond to the recommendation to change the attic access, we have another level/tower just above the bathroom. Thanks for identifying that eyesore. We may have to look at other options.

Thanks

Here are a few walk through pictures. (Still learning how to upload pictures, lol)

I couldn't figure out how to add more than one picture so I apologize for multiple postings.
