You are going to want more than 32" for the toilet. 36" is standard (and perhaps even code in some areas???? Not here in Maine but I heard people saying that on other forums...) We have 34" and it feels fine but I dont think I'd want to go much tighter. You could solve that simply by flipping the closet and shower. So, have your shower -rotated 90 degrees and witha glass end wall- at the end of the tub (which is a nice setup you can see in many bathrooms, the tub deck can actually protrude under the shower glass wall and be a ledge or seat in the shower). Then the passageway moves to the left, and you can steal a bit of space from the other closet for the toilet. Either that of have a shorter vanity. 48" isn't a size I'd fight for. It's too short for a double vanity, really (unless you're using one of the new two-faucet 'trough" styles) so why not go down to 42" and have a better toilet area? For resale, though, you should consider a double vanity. Some people I guess expert truly huge ones, like at least 5+' long. But you CAN get smaller ones, Ikea has some great ones for tight spaces. But if you're not selling anytime soon, do what YOU like!! (But I still think you'll want more toilet space...)

I was asked on another thread to post a picture here of my bathroom as it's pretty small, 10 ft x 4ft 10. Some of the things we did to make the small design work: * made whole width of room the size of the shower * tiled to top of wall * used large format tiles in stacked pattern on walls * emphasized width using a horizontal glass accent * kept vanity unit small (24 x 16) * used large format floor tiles * kept colors simple and lines clean * we will also be using a frameless shower door, yet to be installed that will keep it all simple and open looking.

Our bathroom is similarly-sized - about 6' x 10' with the shower and toilet in the same locations as shown in the picture above (we wanted to move the toilet and enlarge the bathroom, but couldn't due to construction of building and location of stack). The difference in ours is that the entrance is to the left of the toilet (where the vanity is in the last picture) and the 60" two-sink vanity is directly across from that (opposite where you show it) (between the vanity and the shower is where our towel hooks are). Based on my experience, I will say that the shower at 32" plus the curb is a fine size for one person, the toilet is a little cramped (and we have nothing to the left but open space). I would definitely think two sinks plus toilet plus the shower all in a row will be cramped. Without a floor plan I can't tell - is there any way to relocate the door and put the vanity on the opposite wall? An alternative would be the kind of vanity that has two integrated sinks (but little storage on the countertop) in 48"?

Windows inside showers are drafty and they rot. You'd need to add changing out the window to the many expenses of moving the tub/shower. Do you USE a tub? A lot of people only have one for supposed 'resale to people with small children'. You can see where I'm going with this...lose the tub and make a shower in a portion of the same space. Least plumbing expense would be to put the shower next to the existing sink -- where the plumbing and drain already exist. This would leave space beyond the shower for at least a linen closet -- possibly for a second vanity and sink. (Check the elbow room and consider if two people would ever use this bathroom at the same time.)
