I am remodeling my primary bathroom. It is currently constructed as two small half-baths. One half-bath has the toilet and a sink; the other has a bathtub/shower and a sink. I want to take down the wall between them and make one room. This will involve moving plumbing, I know. I will have a space about 6 ft wide by 12 ft long. One of the 12 ft walls is an exterior wall (north) and the other is along the hallway and will need to have the door in it.

There are currently two windows along the north wall. I will lose the one window (currently in the tub room), but keep the other. I do want to keep a bathtub, as this will be the only one in the house. This house was built by my in-laws in the mid-50s, so I know the history well. It is a ranch-style house with a full basement (walk-in shower in the basement bathroom).

Things I know I want: heated tile floors, bathtub/shower combination (wider is better), single sink vanity. I want at least a half-wall next to the toilet for grab bars in the future. I want a wider door (current ones are very narrow and would not allow for a walker or wheelchair). Things I know I don't want: grout in the tub/shower area!

One plan I have toyed with would leave the toilet and sink where it is and then add a fairly narrow cupboard and mirror for make up. Drawback is that there is no room for a second sink and counter space is limited.

Another plan is to put the tub across one end and the vanity across the other end. Install the toilet with the back to the hallway and put the doorway between it and the vanity. This is the direction I'm currently leaning.

Any comments or ideas? I live alone, so a single sink is not an issue. However, this bathroom would be the one that dinner guests would use. From that standpoint, the current (two half-baths) configuration is good; however, the doorways remain a problem and I know I want to replace the tub and surround soon. And, frankly, I'm getting tired of going out one door and then going into another as I get ready every day.
