I can recommend Bartok Design without reservation. Although the relevant construction project is still underway and I have not used the recently-ordered tub, I have seen it and the workmanship looks excellent. Having lived in Japan, I believe that your client is best served by a hinoki tub, instead of a locally sourced alternative. In our experience, Bartok Design were very co-operative, communicative and easy to work with. Let me know if you require any further information.
