Finally, ensure that the shape of the bathtub is one which fits best with your lifestyle. If you’re looking for a bathtub that you will be primarily lying down in, it better to opt for one with a wide oval shape. Shapes along those lines will best fit a human body which is larger around the center. If you’re looking to possibly install glass doors or cannot decide between having a tub and a stand in shower, opt for a rectangular shaped bathtub. Rectangular shaped bathtubs can function as a stand in just as well as a regular stand in shower. Bottom line, ensure the shape of your tub goes well with how you want to functionally use it on a daily basis.
