You’d like to make the bathroom your own private retreat, where you can soak away your cares and worries, relax and recharge. You’ve seen the ads and how-to articles that tempt you to fill up the tub with scented water, grab a book and a glass of wine and even a bath pillow, and take some time off or yourself. But the unfortunate reality is that your old, chipped and discolored bath tub isn’t quite up to creating the home spa you dream of. At least, not yet. But with some very minor bathtub repair and re-enameling, you can get a gleaming new surface and even new colors. The best part is that you won’t have to break the bank to pay for the bathtub refinish, as it is surprisingly affordable.
