I'n not sure if you will even need the other 2 recessed lights in that size space. I guess it depends on how much light the fan will give. I have a bath that is 5 x 7 and we have the lights over the vanity (2 -60 watt) and a 4 in recessed light in the shower and that seems fine to me. But if you want them, why not have them over the center aisle? I assume the lights on either side of the vanity are good task lights?

Sorry I'm so late getting back to you. I think that oddly sized fixtures can be off-putting. Many home buyers are looking for an "ideal" and they can't see past that. If the tub is well made and the bath is located where it's most needed a shorter size tub might not be a problem. If the bath will be used by children then its size is less important, but children grow into teenagers. acm voiced a concern I had about the location of this bath to nearby bedrooms. My mistake in calling it water-resistant drywall. It looks like drywall but it's better referred to as tile backer board. It's most often 1/2 inch thick but I have seen a Hardie brand backer that was only 1/4" thick and came in 3 x 5 ft. sections. HERE is a link to more info on these. There are several types with differing properties. On toilet location, I don't think "obstruction refers to the nearest wall or fixture. I think it refers to something directly in front of the toilet. Looking at your floor plan an angled toilet would not have anything in front of it. There might be room between the toilet and the vanity for a waste basket.

"Who's eye level? A 5 foot person's? or a 6'4" person? Quite different." I'm 5'3" and I live alone, so most of my art hangs so that the center of the work fall at around 60." If my 6' boyfriend and I ever live together, I'll probably split the difference. I believe that 57" is standard "gallery height." That said, I have art in my home that is much lower, and some that is higher, depending on furniture and other features in my home. It's not a hard & fast rule, but it is a good rule of thumb.

You may have already thought about this, but dimmer switches will make whatever lighting scheme you decide on more flexible. Also, think about where furniture will be before placing the recessed lighting. 18 months ago we moved into a 25 year old house that had a finished basement (also with some windows, like yours). While they at least had dimmers on the recessed lighting, the placement of some of the cans was puzzling, even considering where they had their furniture when we saw the house before purchasing (the previous owners did the basement fit-out). I like the one room that has cans in the four corners and a central fixture which is a semi-flush 3-light (the cans are placed about two feet from the walls). The result is that the room is lit very evenly without the use of any table or floor lamps. I use the room for an office so I have a desk lamp for task lighting. Even if you don't use the other part of your basement, if you finish it so it could be used for a family room it will be good for your resale value. The next owners may want to put their teenagers down there with a big television. :-) I love the idea of the full bathroom. That is something I don't have in mine.
