If you’re looking into how to redo your bathtub, it’s likely for one of two reasons: the tub has flaked, cracked, and rusted over years of use, or it simply doesn’t fit your style. Fortunately, reglazing the bathtub can remedy both issues. We’ll break down what reglazing is, if it’s worth doing, and how to do it. That way your bathtub can be a place of peace and relaxation, as intended—no stress involved.

What Is Bathtub Reglazing?

Reglazing is the process of removing a tub’s old coating and applying a new layer, usually an epoxy resin. It’s a cost-effective way to improve your current bathtub instead of purchasing a new one. 

Most bathtubs can be reglazed, including ones made of steel, cast iron, fiberglass, and acrylic, unless they have severe damage or leaks. Reglazing is one of several ways to refinish a bathtub, along with repainting, installing a bathtub liner, or adding a bathtub inlay. 

Why Reglaze a Bathtub

Reglazing is the most common way to refinish a bathtub because it fixes several problems at once:

  • Damage: All sorts of damage can befall a bathtub, whether it’s a one-time accident or gradual deterioration. A shower caddy can fall and gouge the tub, for example. A lack of structural support can cause a crack at your feet. 

  • Discoloration: Your bathtub might have been pristinely white when you bought it, but it’s natural for porcelain or fiberglass to yellow or fade over time. 

  • Outdated design: Whether you’ve grown tired of your bathtub’s current style or you’ve moved into a new place and the tub is stuck in the 60s, an aesthetic revamp is a reason to reglaze.

However, there are issues that reglazing can’t fix. You may need to purchase a new bathtub or hire a local plumber to do a more serious repair. These larger issues include broken pipes, structural damage underneath the tub, and widespread mold.

If you choose to reglaze your bathtub yourself, here are the basic steps:

  1. Purchase a refinishing kit. This covers the must-have materials like epoxy resin, hardener, and primer. Refinishing kits can be found at most hardware stores and cost between $30 to $150.

  2. Remove the caulk and bathtub hardware, namely the spout and drain plate.

  3. Ventilate the room. The next few steps involve potentially dangerous fumes, so safety is important.

  4. Clean the bathtub. This ensures that the epoxy applies correctly.

  5. Remove the old glaze. Apply a combination of etching powder and water to the bathtub and scrub it with an abrasive pad.

  6. Sand the bathtub. Use 400-grit or 600-grit wet/dry sandpaper on all areas, then rinse, wipe, and dry the tub.

  7. Apply primer. This should come in your refinishing kit and can be applied with a brush or roller.

  8. Apply epoxy coating. Mix epoxy resin with hardener and apply the solution to the bathtub’s entire surface with a brush or roller. You’ll likely need to apply two coats but consult the kit instructions beforehand. 

  9. Recaulk and reinstall hardware. After your tub is sealed and the spout and drain cover are back in place, all that’s left is to wait until the epoxy cures.

Cost to Reglaze a Bathtub

Saving money is one of the biggest benefits of reglazing your bathtub. The cost to professionally refinish a bathtub ranges from around $300 to $900, with an average cost of $480. Even if your refinishing project falls on the higher end of that range, it would likely be cheaper than purchasing a brand-new bathtub. With installation and plumbing factored in, replacing a bathtub costs $5,520 on average. Homeowners can save even more money by reglazing the bathtub on their own—the materials needed for a DIY refinish cost about $150.

DIY vs. Hiring a Pro

Reglazing can be done in a few hours, but it has several hands-on steps and requires harsh chemicals, which is why we recommend that most homeowners find a local bathtub refinisher for the job. Naturally, hiring a contractor costs more than going the DIY route, but the expenses can end up fairly close if you have to buy several tools and materials needed for reglazing. 

Frequently Asked Questions

Typically, you need to wait two to three days after reglazing before using your bathtub. This allows the epoxy resin to cure properly. However, the exact time can vary depending on the materials used. Some quick-dry epoxy kits cure in as little as 12 hours, while others may have a four-hour cure time, allowing for same-day use. To ensure the epoxy dries correctly, ventilate the bathroom well. Always check the manufacturer’s instructions and consult with your reglazing professional for specific guidance on when it is safe to use the tub.

Two alternatives to reglazing are installing a bathtub inlay or a bathtub liner. An inlay is a low-priced mat that adheres to the bottom of a bathtub or shower. It’s useful for sealing minor leaks and concealing damage on the bottom of a tub. On the other hand, a bathtub liner is essentially a protective casing that goes over the entire tub. They are usually custom-fit and cost more than reglazing yet don’t last as long.
