We love art in the bathroom, and definitely think that bathroom-themed art doesn't have to be bad. So we love this print from Etsy seller Doodle and Hoob - "medicine cabinet for SAD afflictee." We would love to have a medicine cabinet that looked like this, and agree that it would be great for shaking away those winter blues. The next best thing is probably this print hanging in the bathroom.
Available from Doodle and Hoob's etsy store for $15.
