Refinishing your own bathtub might seem like a clever way to save money, especially if you’ve seen those DIY kits promising a like-new look in just a few hours. But here's the truth: while the idea of giving your old tub a facelift is appealing, one wrong move can turn a weekend project into a costly disaster.

If you're considering tackling this on your own, there are some important DIY bathtub refinishing tips you should know before picking up that brush or spray can. In this article, we'll walk you through the pros and cons of DIY refinishing, what materials you'll need, and when it’s better to call in a pro.

(If you'd rather let the pros handle it, Bathtub Made New offers professional refinishing services that deliver beautiful, long-lasting results.)

What Is Bathtub Refinishing?

Bathtub refinishing—also called resurfacing or reglazing—is the process of restoring the surface of a worn or outdated tub. Rather than replacing the entire unit, a new finish is applied over the existing surface. This process involves cleaning, repairing chips or cracks, applying bonding agents, and finishing with a durable topcoat.

It’s not simply painting your bathtub. True refinishing involves several steps to ensure the coating bonds properly and holds up under daily use.

Common Types of DIY Bathtub Refinishing Kits

When homeowners opt for a DIY approach, they typically use one of these products:

  • Spray-on epoxy kits: These offer a smooth finish but require a very controlled environment.

  • Roll-on kits: Easier to apply but often leave brush marks or bubbles if not done carefully.

  • Tub paint: Less durable than epoxy and not recommended for long-term solutions.

Many kits advertise quick drying and easy application. However, most don’t provide the same quality materials or bonding agents used by professionals.

Pros of DIY Bathtub Refinishing

We won’t lie—there are some benefits to DIY bathtub refinishing if everything goes perfectly.

  • Lower upfront cost: DIY kits usually cost between $50 and $100.

  • Convenience: You can start whenever you're ready.

  • Satisfaction: There’s a certain pride in completing home improvements yourself.

  • Short-term use: If you're refreshing a rental property or planning to remodel soon, a quick DIY may be enough.

The Risks and Limitations of DIY Kits

Here’s where it gets tricky. The surface of a tub must be properly prepped, cleaned, etched, and dried for the refinishing to last. That’s where many DIY jobs go wrong.

  • Uneven coating: Drips, brush marks, and bubbles are common mistakes.

  • Poor adhesion: Without professional-grade bonding agents, the finish may peel within months.

  • Toxic fumes: Many DIY kits contain strong chemicals that require professional ventilation systems.

  • Messy application: Overspray can damage tile, walls, and fixtures.

  • Shorter lifespan: Most DIY jobs last 1–3 years. A professional refinish can last 10–15 years with proper care.

What You Need to Get It Right

If you’re still determined to go the DIY route, here’s what you’ll need to give yourself the best shot at success:

  • Full cleaning and etching kit

  • Protective gear (gloves, goggles, and a respirator)

  • Painter’s tape and plastic sheeting to protect surrounding areas

  • Proper ventilation (open windows, exhaust fans)

  • Quality epoxy refinishing product

  • Application tools like foam rollers or spray guns

  • Drying time: Plan for 24–48 hours of curing with zero water contact

Even with all of this, the smallest error in surface prep can ruin the finish.

When DIY Isn’t Worth It

Some tubs simply aren't suited for DIY work:

  • Antique cast iron tubs: These require special tools and coatings.

  • Tubs with cracks or deep chips: Surface refinishing won’t fix structural damage.

  • Homes going on the market: A poor DIY job can reduce home value.

  • High-end bathrooms: You don’t want a visible DIY job next to granite counters and modern tile.

Professional vs. DIY: Is It Really Cheaper?

Let’s talk numbers.

  • DIY Kit: $150 average + your time + tools you may not have

  • Professional Service: $650–$1,000 average with a 10–15 year lifespan

Now factor in possible repairs from a failed DIY—stripping and redoing a bad job often costs more than hiring a professional in the first place.

And don’t forget the value of time. A pro refinisher completes the job in one day with minimal mess.

Is DIY Bathtub Refinishing Right for You?

Ask yourself:

  • Are you comfortable using harsh chemicals?

  • Do you have a properly ventilated space?

  • Can you dedicate multiple days to prep, apply, and let the finish cure?

  • Are you OK with a result that may not last more than a year or two?

If any answer is "no," hiring a professional may be the smarter choice.
