Forget porcelain, plastic or -gasp- metal. This is the real deal: an eco-sustainable larch bath tub that is not only fully functional, but also a pretty neat element of design. Smooth to the touch and warm on the eyes, it’s no surprise we all want a wood-based bath tub in our bathrooms right now. Especially since it looks so darn inviting. It requires a little extra care though: make sure that you use only mild soaps when cleaning, that you keep that water temperature below 140-degrees Fahrenheit and that you rinse out after each use.
