Let’s take a closer look at the tub replacement versus tub reglazing debate, so you can choose which option is best for your situation. It’s wise to consider everything involved with a bathtub replacement before you decide what to do about your grimy old bathtub.
Replacing an existing bathtub with a newer model is not always a simple chore. The original tub almost always needs to be cut into pieces to fit through the bathroom door. There might also be flooring, trim, surrounds, and plumbing that will need to be removed and replaced. When you remove an old tub and bring in a new one, the plumbing fixtures may need to be replaced or adjusted to fit the new model. While a new tub can cost as little as $300, labor expenses for the replacement process can easily add $3,500 or more to the bill.
Instead, many homeowners have the existing tub reglazed or refinished, which typically costs $350-$750, depending on the area and process. If your bathtub is dingy and stained, or even if it sports some serious rust and cracks, a trained professional can likely fix and re-coat the surface for a like-new look.
Disadvantages: Reglazed tubs require special care, so you should avoid using harsh chemicals to clean a newly surfaced unit.
