I think you need to decide if you want one bath or two. If you want two baths, you definitely need to figure out how to add another toilet. Also, I think it would be much nicer to have a bigger shower. Personally, I would rather share a nice bath with a roommate than have the chopped up room you have now. I would close off the door to the bedroom, remove the door in the middle, expand the shower another foot, remove all of the pony walls, and rotate the bottom sink around to mirror the top sink. I would also move a light fixture to the new center of the now-square room. If it is possible to move the toilet, another option might be enclose the toilet in its own little space with a pocket door, maybe where the shower is now. Then, move the shower to where the lower sink is, and expand the upper sink into a double vanity. It can be nice, if two people are sharing the bath, to have the toilet in its own enclosed space.

Thank you all for posting this question and answering it - I have the same question :) So, can I just use a "kitchen" cabinet pull for a handle - I am thinking of using the one in my link - as I am looking for a handle with clean contemporary lines and I too don't think I want to use the traditional type of pocket door finger pull and have been wondering if it is possible to install a cabinet pull vertically on the door (like you would on a upper kitchen cabinet) instead. If you think it would work, what size pull do you think is the best - 8" maybe??? We do not need the door to go all the way into it's "pocket" either and they do not need to lock. I guess I am concerned that cabinet hardware would not be strong enough to use. If you can recommend a company that sells contemporary, clean lines door pulls for this purpose I would appreciate any help. Thanks Piaa Here is a link that might be useful: Cabinet Pull

Thanks everyone. I appreciate your comments. The bathroom is a total gut job, moving all the plumbing around to make it more functional. More expense than I wanted, but with 3 daughters sharing it, I figure it's worth it in the long term. We have pocket doors elsewhere in the house, and I absolutely love them. The pocket door will be in a wall that will indeed have plumbing on the tub side. I'm figuring, based on what GC has said, that the wall will be about 10" thick. Might not be the optimum situation, but I'd rather have that than put the plumbing on the other end of the tub, which would place it in an outside wall. If I can figure it out, I'll post a floorplan. We won't be starting this project for at least another month, but I'm kinda OCD (or maybe anal!) about things, so I'm trying to work out every last detail ahead of time.

Thank you all so much for your feedback! I have incorporated a lot of your comments into the design. I am going to propose the following changes to the builder (we are mid framing): Increase French door width to 6 feet. Make the 3 foot door panel closest to sink fixed. Make the functional 3 foot door near tub swing inward. I will have him keep the doors pretty much centered on the bedroom vault but go over one foot longer to accommodate the extra foot (especially since really shouldn’t get closer to sink). This will also make the bathroom seem more balanced I think and the operable door with open to the chandelier in the bathroom. I will also place a large full length mirror on back wall next to linen closet which will reflect light from large bedroom window feature (and hopefully be more attractive than looking at plain wall or side of bathroom door) Change shower door swing and add a towel bar on door (this is brilliant!). Should the towel bar be on outside of door itself or to the left? Change WC door to be a pocket door to eliminate the look of so many doors and so don’t have to look at it when open (and we often would probably leave it open so this way it doesn’t block mirror). I will have to ask contractor about this but I suspect he could do pocket door into the open attic space. I will change the direction and swing of both closet doors and will also ask about cost to upgrade them to French doors (well single door but glass with divided panes— and will do white curtain on back like suggested). Do you think it’s worth it to upgrade linen closet to same door? Thank you for all the suggestions!!
