wine barrel tub, natural carved chair, branch for holding robes and the natural branch light shade. I bet I could do a wood paneling thing around an already exiting bathtub with the cap to mimic the vibe but still have functional shape and size.
Hot water tank heated by wood burning stove. From Teach Nollaig, Tiny house in Ireland. Could be improved by adding a small sterling engine to power a circulation pump, allowing the hot water tank to be up higher [improving pressure]. Also INSULATION!
