Here is another good website with some great ideas.
Here is a link that might be useful: Living Large in a Small House
You've been busy. I've been to BG site before. If you sign up they will send new articles. Although I hadn't seen the narrow bath pics/article before. These are new and worth a look. Most of the baths posted on our forum have very similar layouts as the site pics. Well worth a stroll.
There are so many ideas I would love to have. But I run into things like the pic with two window seats and a heavenly arch over the builtins. I'd love to have something like that in my kitchen, but there isn't any place to even begin the possibility. So we really have to be creative in considering a like design. Although I have been thinking about redoing my art/office room and their design is a great start.
