Bathtubs can often be restored to like-new condition, or else updated with a modern refinishing or reglazing. Not only will your refinished bathtub look better, but it will also be better protected against water, mold, and other environmental threats.
Of course, you could always replace your bathtub. However, there are several benefits to reglazing/refinishing your tub instead, including:
Less waste (save a tub from the landfill!)
All work is done on-site
Your tub stays in place
Work can often be completed more quickly
Ultimately, reglazing and refinishing your bathtub is easier on the environment, your wallet, and your life. Yet the end product will be a bathtub that looks new, or often enough, even better than new.
