Spa inspired bathtubs such as the  free standing resin soaking tubs, have become a popular choice for individuals looking to add a sculptural element to their bathroom decor. These tubs do not include features such as jets or bubbles, letting you enjoy a deep quiet soak, just like old times. While relatively new to the market, solid surface resin tubs retain heat well, and come in a variety of shapes and sizes, making them a great choice for easily adding a touch of sophisticated elegance with spa-like appeal.
