We have never been to Scotland so this comes from research, not experience. This company represents several B&Bs http://www.scotland2000.com/accom/west/index.htm

Some, such as Holly House http://www.scotland2000.com/hollyhouse/ offer rooms with private or shared bathrooms, so be specific.

There are many others, these for instance: http://www.innsite.com/inns/B009297.html http://www.innsite.com/inns/B008303.html
