A Book Wall bookshelf in the bathroom may be a less common setting in the bathroom, but if you are relaxing by the Japanese designer foam Spa (foam SPA) designed by LIXIL, you may need such an unconventional configuration. This bathtub uses unique technology, and its air and water control system allows you to be soaked in the bathtub during the entire package, soaking for a long time will not suffer any skin damage. With this kind of bathtub, there must be more books on hand. Bring your love of books into the bathroom! Your bathroom may not need to fill books like the two examples above, but it's cool to combine books with bathroom space. For example, this bathroom hidden behind a Book wall, every time you enter the bathroom, you can grab a book! The secret bathroom hidden behind the study. It's both a bathtub and a bookshelf. A book when you take a bath! Adding a few books to the bathroom doesn't mean you have to put a big, high-end bookshelf here as the bathroom background. In fact, one or two smaller, more low-key bookshelves or reading corners in the bathroom are more popular and practical.
