Should you repair the black stains and water leaks in your hinoki bath? This explains the limitations of partial repairs and the benefits of replacing it with a new hinoki bath that has waterproof coating technology with 20 years of experience.

If you notice black stains or water leaks in your hinoki bath, partial "repairs" are likely to be a temporary fix. Due to the characteristics of natural wood, it is often the case that a large portion is already decayed, making a fundamental replacement essential. We propose replacing your bath with a highly durable hinoki bath designed for the next 20 years for customers considering repairs. Our hinoki baths feature a flexible design that allows installation even in narrow bathroom entrances where standard poly baths cannot be delivered. Additionally, sizes can be specified in 1 cm increments, including depth, resulting in an ideal bathtub without waste. With our unique waterproof coating technology honed over 20 years in hot spring facilities and the drying know-how of nine generations of lumber merchants, we effectively suppress the issues of black stains and water leaks that have troubled repairs. We offer customizable designs tailored to your lifestyle, including luxurious jet bath options and easy-to-maintain unit bath specifications. Please check our reliable technical capabilities, which boast successful implementations such as at "Tatami Inn Chatan Mihama," in the downloadable materials. *For more details, please refer to the PDF download button.
