In a situation where land resources are lacking, population growth is rapidly rising, and houses and cost of living are ever increasing, Inflatable Bathtub is a general public design that everyone will probably need. As more ordinary citizens make the switch to smaller apartments and houses, the way they use small spaces must also be carefully considered. Not only does the design of Inflatable Bathtub allow for a more spacious bathroom than before, it also allows users to choose their preferred way of bathing. When a bath is needed, simply press the button once to open up the bathtub. When a shower is needed, a shower can be achieved by leaving the Inflatable Bathtub in its ‘storage mode’.
