Adding plants to the bathroom is good feng shui, as it gives off a sense of serenity. 
Bring nature inside. It doesn’t have to be a tree. With just some simple air plants, succulents or even the so popular Sansevieria trifasciata better known as Snake plant; the room will acquired a more relax eco-friendly look. 
Stylish bathroom design idea with decorative furniture from concrete is derived from Art-Tic Design Studio. Wide range of bathroom furniture is made of concrete elements such as sinks and bathtubs concrete. In addition, other parts of the bathroom like floor and walls is composed of concrete elements. The bathroom was cold and quiet, with a gray color and pattern typical of the concrete surface gives a different sensation to the bathroom decor. 
Designers James Wong and David Cubero created the ultimate garden bathroom retreat complete with supreme luxury in the Burgbad Sanctuary. This extremely lush garden both complements and accents the intimate outdoor bathing room. The bright and deep greens contrast the reds and oranges in the glass and wood encased quarters, while the orange lotus flowers and brightly colored fish accent the rich colors of the wood.
