I have discovered a new company in Vancouver, BC, Canada that offers Freestanding Wood Bathtubs and Wood Sinks.  They have a incredible selection and a lots of Wood Types to choose from. I enjoyed the warmth and natural look of the bathroom. Definitely worth looking into it if you want to transform your bath into a more natural, relaxation-focused room.
The added bonus is that all their Wooden Bathtubs and Wooden Sinks are made in Germany and shipped directly to your home.
