Wow!!!!! I am happy to see you guys made such an effort to make it so nice and stylish! :) My first barn was, well you could hardly call it a bathroom. It was a tiny closet with a very unhygienic toilet, and a garage sink with only cold running water and there was never anything to dry your hands with... or wash them for that matter. O.o My new barns bathroom is much better. It's clean and has soap and paper but is sadly not as nice as this!
Gosh I wouldn't' be surprised if you had business boom because of this bathroom. Potential boarders will just see the bathroom before they see the stalls and they'll sign up. ;)
A ride a day keeps the worries away!
