Why Bathtub Reglazing Peels—And How to Avoid It?

A freshly reglazed bathtub can completely transform the look of your bathroom. It’s clean, glossy, and gives the impression of a brand-new installation—without the hefty price tag. But what happens when that beautiful surface starts to peel, bubble, or chip just months after the job?

You're not alone. Peeling bathtub reglaze is one of the most common complaints homeowners have after refinishing. The good news? It’s preventable.

In this article, we’ll walk you through why reglazing peels, how to avoid common mistakes, and what to do if you’re already dealing with the problem. You’ll also learn what separates a professional-grade job from a DIY disaster.

What Is Bathtub Reglazing?

Bathtub reglazing—also known as refinishing, resurfacing, or re-enameling—is a cost-effective way to restore an old or worn-out tub. The process typically involves:

• Cleaning and stripping the existing surface

• Sanding and etching to create a bond

• Applying a primer

• Finishing with a topcoat, often made of epoxy or urethane

Most homeowners opt for reglazing because replacing a bathtub is expensive. According to HomeAdvisor, reglazing costs between $300 and $600, while replacement can cost $2,000 or more once plumbing, labor, and tile work are factored in.

It’s a smart solution—when done correctly.

Why Does Bathtub Reglazing Peel?

Peeling is one of the clearest signs that something went wrong during the reglazing process. Understanding the causes can help you avoid them, or know what to look for if you're hiring a contractor.

1. Poor Surface Preparation

This is the number one reason reglaze jobs fail.

Before any coating is applied, the tub must be thoroughly cleaned, degreased, and stripped of any previous glaze, soap scum, or residue. If this step is rushed or skipped, the new surface won’t bond properly—and it will peel, often within months.

Even a small patch of residue can compromise the entire finish.

2. Low-Quality Materials

Some DIY kits or budget contractors use low-grade primers or topcoats. These may look great initially, but they don’t hold up well in a moisture-heavy environment like a bathroom.

Look for contractors who use ASTM-compliant products and coatings specifically designed for porcelain, acrylic, or fiberglass tubs.

3. DIY Reglazing Without Proper Tools

It’s tempting to try this yourself, especially with so many refinishing kits available online. However, DIY reglazing often leads to premature peeling.

Professionals use industrial equipment that ensures proper etching, layering, and curing. Most homeowners don’t have the tools—or training—to get that level of quality. Even minor mistakes in sanding or spraying can cause issues.

4. Improper Curing Time

After a tub is reglazed, it must cure for 48 to 72 hours. Using the tub too soon is one of the fastest ways to ruin a new finish.

Many homeowners make the mistake of using their tub within 24 hours. Unfortunately, once moisture gets under the surface, it causes bubbling, cracking, and eventually peeling.

5. Poor Ventilation or Moisture Control

Humidity is another major culprit.

If your bathroom doesn’t have proper ventilation, condensation can affect the curing process. Peeling may start around the drain, overflow, or corners—areas most prone to water exposure.

We recommend using a bathroom fan or dehumidifier during and after refinishing to control moisture levels.

6. Reglazing Over an Old Reglaze

If your tub has been refinished before, the previous coating must be completely stripped away. Reglazing over old, deteriorating layers may seem like a shortcut, but it creates a weak foundation.

The new coating will peel along with the old one—wasting your time and money.

How to Avoid Peeling and Extend the Life of Your Refinished Tub?

Now that you know what causes peeling, let’s talk about how to avoid it. A high-quality reglazing job should last 8 to 15 years when properly maintained.

Here’s how to make that happen.

1. Hire a Certified Professional

Always ask if your refinisher is EPA Lead-Safe Certified (especially for homes built before 1978) and whether they’re insured and bonded.

Look for:

• Real customer reviews

• Before and after photos

• A written warranty (ideally 3 to 5 years)

Professionals also use commercial-grade coatings, which are significantly more durable than DIY products.

2. Use the Right Materials

High-quality reglazing jobs use:

• Epoxy or acrylic urethane primers

• Catalyzed coatings that chemically bond with the surface

• Adhesion promoters (especially for fiberglass tubs)

Using proper materials reduces the risk of blistering and peeling. Some companies may even offer odorless, fast-drying options for quicker turnaround.

3. Wait Before Using the Tub

Let the tub cure completely before use—no shortcuts.

We recommend:

• Minimum 48 hours for epoxy-based finishes

• Up to 72 hours for cooler, humid climates

• Avoid cleaning or placing bathmats during this time

4. Maintain the Surface Properly

Once cured, maintenance is key to preserving the finish.

Do:

• Clean with mild, non-abrasive cleaners

• Use soft cloths or sponges

Avoid:

• Bleach-based products

• Scrub brushes or scouring pads

• Bathmats with suction cups (they can cause peeling)
