There’s nothing quite like a sparkling, new bathtub to give your bathroom that fresh, luxurious feel. But over time, even the best-kept bathtubs can start to show signs of wear—scratches, stains, chips, or discoloration that make your once-beautiful tub look tired and old. That’s where a Do-It-Yourself (DIY) bathtub refinishing kit comes in. With the right tools and techniques, you can restore your bathtub’s original charm without the cost and hassle of a full replacement.
This comprehensive guide will walk you through the entire process of refinishing your bathtub, step-by-step. Whether your tub is made of porcelain, fiberglass, or acrylic, a DIY refinishing kit can breathe new life into it. This method not only saves you money, but it also avoids the mess of demolition and installation.
Why Refinish Instead of Replace?
Before diving into the process, let’s explore why refinishing might be the better choice over replacing your bathtub entirely.
Cost Savings
One of the most compelling reasons to choose a DIY refinishing kit is the potential for significant cost savings. Replacing a bathtub can be expensive—when you factor in the cost of a new tub, labor, demolition, plumbing adjustments, and tile repairs, the total cost can easily rise into the thousands. In contrast, a refinishing kit typically costs between $50 and $150, depending on the brand and quality. This makes refinishing a much more budget-friendly option for most homeowners.
Less Disruption
Replacing a bathtub is no small task. It can take several days and often requires skilled labor to remove the old tub, make plumbing adjustments, and install the new one. Refinishing, on the other hand, can usually be completed over a weekend. The refinishing process is relatively quick and doesn’t require tearing out walls or dealing with major construction dust. Once you’re done, your bathroom is immediately usable again after a short curing period.
Extending the Life of Your Tub
If your tub is still structurally sound but is suffering from cosmetic issues like chips, cracks, or stains, refinishing is a great way to extend its life. Porcelain, fiberglass, and acrylic bathtubs can all benefit from refinishing, and the process helps protect the surface of your tub from further wear and damage.
What You Need for DIY Bathtub Refinishing
Before you start the refinishing process, you’ll need to gather all the necessary tools and materials. Most DIY bathtub refinishing kits include the essentials, but you may need a few additional items. Here's what you’ll need:
- DIY Bathtub Refinishing Kit: This typically includes epoxy or resin, hardener, and possibly an applicator or spray gun.
- Safety Gear: Gloves, a mask, and safety goggles are essential to protect yourself from fumes and chemicals.
- Painter’s Tape: Use this to mask off areas around the tub, like the faucet, drain, and any tile or surfaces you don’t want to be painted.
- Plastic Sheeting: Cover the bathroom floor and any other surfaces near the tub to protect them from drips and splatters.
- Cleaner: A strong tub cleaner to remove soap scum, dirt, and oils before you begin the refinishing process.
- Sandpaper: You’ll need a variety of sandpaper grits, typically 220 to 400, to sand down rough areas and create a surface that the refinishing material can adhere to.
- Putty or Filler: If your tub has chips, cracks, or dents, you’ll need a filler to repair those imperfections before you begin refinishing.
- Paint Roller or Spray Gun: Depending on your refinishing kit, you’ll apply the refinishing coat using either a roller or a spray gun.
Step 1: Prepare the Area
Protect the Bathroom
Before you begin any refinishing, you’ll want to protect the surrounding area. Refinishing kits contain chemicals that can damage other surfaces if spilled. Use painter’s tape to carefully mask off the edges of your tub where it meets the tiles, faucet, and drain. Cover your bathroom floor and any nearby fixtures with plastic sheeting to protect them from overspray or drips.
Ensure Proper Ventilation
DIY bathtub refinishing kits often contain strong fumes. Be sure your bathroom is well-ventilated before starting. Open windows, turn on an exhaust fan, and wear a mask to avoid inhaling the fumes. This is particularly important if you are working in a small, enclosed bathroom.
Step 2: Clean and Sand the Bathtub
Clean the Tub Thoroughly
A clean surface is critical to achieving a smooth and durable refinished tub. Use a strong cleaner, such as bleach, ammonia, or an abrasive cleaner, to scrub the entire surface of the tub. Make sure to remove all soap scum, oils, and grime. Be thorough in this step, as any residue left behind can cause the refinishing material to peel or fail to adhere.
Sand the Surface
After cleaning, sand the entire surface of the tub. Sanding is important because it roughens up the tub’s surface, allowing the new finish to stick better. Start with a medium-grit sandpaper (around 220-grit) to remove any gloss from the surface, then move to a finer grit (around 400-grit) for a smoother finish. Don’t forget to focus on areas with chips or scratches—this will help the refinishing material fill in those imperfections.
Once sanding is complete, wipe down the tub with a damp cloth to remove any dust. Allow the surface to dry completely before moving on to the next step.
Step 3: Repair Cracks and Chips
If your bathtub has any cracks, dents, or chips, now is the time to fix them. Most refinishing kits come with a filler or putty that you can use to repair these damaged areas. Apply the filler with a putty knife and smooth it out until it’s level with the rest of the tub. Once the filler has dried, sand it down with fine-grit sandpaper to ensure a smooth finish. Proper repair of cracks and chips will ensure that the final result looks professional and lasts longer.
Step 4: Apply the Refinishing Coating
Mix the Refinishing Solution
Most DIY bathtub refinishing kits include two components: an epoxy resin and a hardener. Follow the kit’s instructions to mix these components together. It’s important to get the ratio correct to ensure a smooth, even finish.
Apply the First Coat
Once the refinishing solution is ready, use either a spray gun or roller to apply the first coat to the bathtub. Spray application often provides a smoother, more professional finish, but a roller can also work well if used carefully. Start at one end of the tub and apply the coating in thin, even layers. Be careful not to overload the roller or spray gun, as this can cause drips and uneven coverage.
Allow the first coat to dry for the recommended time. This could take anywhere from 30 minutes to a few hours, depending on the product and environmental conditions.
Step 5: Apply Additional Coats
Most bathtubs require at least two to three coats of refinishing solution for a durable, long-lasting finish. After the first coat has dried, lightly sand the surface with fine-grit sandpaper (about 400-grit) to ensure the next coat adheres smoothly. Wipe away any dust, then apply the second coat in the same manner as the first.
Repeat this process for a third coat if necessary. Applying multiple coats ensures a high-gloss, durable finish that will stand up to daily use.
Step 6: Curing Time
Once you’ve applied the final coat, it’s crucial to let the refinishing material cure properly. Most DIY kits recommend a curing time of at least 24 to 48 hours before you use the tub. During this time, avoid touching the tub or placing anything on its surface. This will ensure the finish sets correctly, preventing any imperfections or damage.
Step 7: Clean Up and Reassemble
After the curing period is complete, carefully remove the painter’s tape and plastic sheeting. Reinstall any hardware, such as the drain, faucet, or overflow plate, that you removed at the beginning of the process. Give the tub a final wipe down to remove any dust or residue, and your bathtub is ready for use!
Is DIY Refinishing the Right Choice for You?
While refinishing your bathtub yourself can save money, it’s not always the perfect solution for every situation. If your tub is heavily damaged or structurally compromised, refinishing may only provide a temporary fix. In such cases, replacing the tub might be a better long-term investment.
If you’re ready for a complete bathroom upgrade, consider swapping your old tub for a sleek, modern model like the LY Compact Soaking Tub or the LY Egg-Shaped Freestanding Soaking Tub from ACE DECOR. These tubs offer a combination of style and comfort, perfect for a modern bathroom refresh.
