If you can imagine it, we can make it (almost). We have no “standard” sizes and most every Ofuro we have made over the last 20 years has been customized to the needs and desires of the client in one way or another. We’ve made them as large as 7′ x 5′ x 4′ deep , and as small as 2′ x 2′ x 2′. Although we have made them as long as 8′, currently the largest Ofuro we’ll make is 8’x8′
As the size of the Ofuro increases, the thickness of the walls increase as well and this is based on the gallon capacity of the tub.
