If you are remodeling or renovating a bathroom, removing a tub or shower for replacement provides the perfect opportunity to make your home more energy efficient. While you are removing old plumbing fixtures or remodeling the layout of the room, open the walls behind the shower and the tub to check for adequate insulation and to find any cracks in wall seams. Because you are working with these walls anyway, the additional expense of upgrading the insulation in the walls and sealing potential air leaks will be relatively small. This expenditure will more than pay for itself in savings on heating and cooling costs because you will be losing less conditioned air and admitting less outside air. Many homes have not been insulated well or carefully sealed behind showers and tubs. You can spend a small amount of money on insulation, caulk or expanding foam, improve the insulation of the room, as well as your comfort in the room, and make your home more energy-efficient.
