Where or from whom can I obtain a traditional japanese soaking tub, called an OFURO?

I have found these sources for traditional Japanese wooden tubs:

Inside Out Enterprises

Robert's Hot Tubs

SeaOtter Woodworks

At the bottom of this page you'll find a list of contractors in
California who have experience in designing Japanese-style bathrooms:

From an article in Forbes:

"Wooden Japanese-style soaking tubs are the new 'in-thing.' These are
deeper than Western tubs, reducing surface heat loss and enabling more
than one bather to be comfortably immersed up to their chins...

In North America, no one makes them like Bay Area-based Robert's Hot
Tubs. The company makes ofuros ($5500), square, wooden tubs crafted
from richly colored teak or aromatic Port Orford cedar. But unlike
Japanese tubs, Robert's Hot Tubs' ofuros are water-tight (thanks to a
special joinery system) and may come outfitted with modern jets as
well as heating and filtration systems.

American Reinforced Plastics makes a round, moderately-priced ($444)
version out of gel-coated fiberglass. ARP plant manager Merle Van
Doren has seen the demand for its Asian-style soaking tub explode in
the past year. It uses everyday plumbing, so there's no need for
special water treatment, heating or filtration. Also, unlike hot tubs,
it's quiet."

Last, but not least, here's an article that describes how you can make
your own Japanese-style wooden tub (I include this mainly for its
amusement value. The thing is mighty ugly!)
