The Keops Evolution Bathtub by Royo Group is a creative solution for space-limited bathrooms. Considering that a lot of people are living in small urban apartments, the chances of owning a home-spa is zero. Luckily, this manufacturer has the solution. It comes with a number of cool features including water- and air-jet massage, perfectly designed headrest and handles, subaquatic light and automatic drying circuit. There are some other home-spa-like features such as dynamic jet massage, ozone therapy, LED lights and aromatherapy. Measuring only 67 by 35 inches, the Keops Evolution Bathtub is small enough to accommodate one person at a time – you win some, you loose some.
