I have been thinking about your post for a while, and building my darkroom at the same time. Are you sure your bathroom is too small? I thought for a long time that mine was. I live in a mobile home, and there is barely enough room for the tub and other facilities, let alone an enlarger. But when I lost the one i was borrowing, I had to do something. I am now over 2 weeks behind in printing (also due to 2 straight weeks of shooting). I suggest you take another look at it. See what you can do. Why? Because it will be easier to light-proof. Esp if you don't have a window in it. More room to move around (stand up straight?).
My concern for working under drapes is the limited ventalation you will have. I am going to see how my design goes and then if it works well, will seal the window and put in a light-proof fan. How are you going to get air in and out of under the drapes?
Would it be easier to lightproof the entire kitchen? Here is how I did the window in my bathroom. Got some heavy black material at Walmart (on sale also!). Only intended to double it over, but got enough to triple it. Stich-witched it (heat tape for sewing) so it stays together, and then put velcro on it. Put velcro on the metal frame around the window. Poof! No light in and no darkness out! That might be an option for your windows, and even the entrance if it is open.
You can get large plastic drapes at Walmart, Kmart, etc. that might only require a couple of them. I would suggest going to a couple of fabric shops (or calling them) and seeing what they can come up with. You might have to sew a couple of pieces together since it comes in a limited width, but length should not be a problem.
Hope this helps.
