Is it possible to have the bath fabricated from Teak wood? If not..which wood that you use wood look good next to teak..perhaps with a stain to bring the wood darker and closer to the Teak?
Our company is specialized in japanese hinoki wood and other softwoods of the cypress family such as sawara or asnaro-hiba. We will not build a tub in teak or any other imported hardwood.
If a tub should ever be built in teak, it should be uretan coated as it would produce an unpleasing smell and anyway it has not therapeutic properties.
About staining hinoki: again, one of the main points of having a japanese wood tub built is the aroma and the natural feeling of untreated wood. By using a stain, these 2 elements would be spoiled.
