How to Refinish a Steel Bathtub

This guide on how to refinish a steel bathtub will walk you through the process, ensuring a professional finish that transforms your bathroom.

Why Refinish a Steel Bathtub?

Refinishing a steel bathtub can provide numerous benefits, both aesthetically and practically.

Firstly, refinishing can improve the appearance of your bathtub and make it look like new. This is especially useful if you have an older bathtub with chips, scratches, or stains that are difficult to remove. By refinishing the tub, you can restore its original shine and smooth surface.

In addition to improving the appearance, refinishing also extends the lifespan of your bathtub. A well-maintained and refinished steel tub can last for many more years compared to one that is left untreated. This can save you money on having to replace the entire tub in the long run.

Needed Materials

To successfully refinish your bathtub, you will need the following materials:

  • Tub and Tile Refinishing Kit (Can Be Purchased at Most Hardware Stores)
  • Chemical Cleaner or Etching Solution
  • Sandpaper (100 Grit, 220 Grit, and 400 Grit)
  • Tape and Plastic Sheets
  • Paintbrushes and Rollers
  • Protective Gear Such as Goggles, Gloves, and a Mask
  • Bucket and Sponge
  • Rubbing Alcohol or Acetone
  • Lint-Free Cloths
  • Caulk and Caulking Gun (If Necessary)

6 Simple Step-by-Step Instructions on How to Refinish a Steel Bathtub

Step 1: Prepare the Tub

Begin by thoroughly cleaning the surface of the bathtub to remove any dirt, grime, or soap scum. Use a chemical cleaner or etching solution, as this will help create a surface that the refinishing material can adhere to effectively. Once the tub is clean, use sandpaper (starting with 100 grit and progressing to finer grits like 220 and 400) to sand down the entire surface of the tub.

Use a Chemical Cleaner 
Or Etching Solution

This step helps to smooth any imperfections and ensure a consistent texture. Finally, protect the surrounding area by applying tape along edges and covering fixtures, walls, and the floor with plastic sheets. Wearing protective gear such as goggles, gloves, and a mask during this process is essential for your safety.

Step 2: Sand the Tub

Start by selecting the appropriate sandpaper to effectively smooth the surface of your tub. Begin with 100-grit sandpaper to tackle any uneven spots or residue left from cleaning. Gradually move to finer grits, such as 220 and then 400, to achieve a polished and uniform texture. Use consistent, even pressure as you sand to avoid creating irregularities.

Be sure to pay close attention to corners and edges where imperfections can easily remain. Once the tub feels smooth to the touch, thoroughly wipe it down with a damp cloth to remove all dust and debris caused by sanding. This step ensures a clean surface that is ready for the next stage of your project.

Step 3: Tape and Cover the Surrounding Area

Before proceeding to the next step, it’s essential to protect the surrounding areas to avoid unintended messes or damage. Use painter’s tape to mask off edges, fixtures, and any other parts of the tub that you do not want to be painted or refinished. Ensure the tape is applied smoothly and securely to prevent paint from seeping underneath.

Additionally, cover nearby walls, floors, and furniture with drop cloths or plastic sheeting to shield them from splatters or overspray. Taking the time to tape and cover everything properly will help you achieve professional-looking results and make cleanup significantly easier.

Step 4: Prime the Tub

Once the preparation is complete, the next step is applying a primer to the tub’s surface. Use a high-quality, epoxy-based primer specifically designed for tubs and tiles. Apply the primer evenly with a brush or roller, ensuring full coverage over the tub’s surface.

Follow the manufacturer’s instructions regarding drying times, as proper curing is essential for the primer to adhere effectively. A well-applied primer not only ensures smooth application of the topcoat but also enhances the durability and finish of the refinished tub.

Step 5: Paint the Tub

Once the primer has fully cured, it’s time to apply the topcoat to the tub. Use a high-quality, epoxy-based paint or a product specifically formulated for refinishing tubs. This will ensure a durable and professional-looking finish. Begin by mixing the paint thoroughly according to the manufacturer’s guidelines. Using a clean brush or roller, apply the paint in even strokes, working in small sections to prevent streaks or uneven coverage.

Paint or a Product Specifically 
Formulated for Refinishing

Allow the first coat to dry completely before applying a second coat, if needed. Follow the recommended drying times carefully, as proper curing is crucial for the paint to bond effectively to the surface. Once the painting is complete, allow the tub to fully cure before exposing it to water or regular use. This final step will leave your tub looking refreshed and as good as new.

Step 6: Add Finishing Touches

Once the paint has completely cured, inspect the tub for any imperfections or missed spots. If necessary, perform small touch-ups using a fine brush to ensure a flawless finish. Reinstall any hardware, such as faucet handles or drain covers, that were removed during the preparation phase.

Finally, clean the surrounding area, removing any painter’s tape and wiping away any dust or debris. These finishing touches will enhance the overall appearance and ensure the longevity of your freshly painted tub.

Following these steps on how to refinish a steel bathtub will not only give your bathroom a new look, but it can also save you money compared to replacing the entire tub. Additionally, by using non-toxic materials and proper ventilation, you can make this a more eco-friendly project.

Maintenance Tips

To keep your refinished steel bathtub looking its best, follow these maintenance tips. Avoid using abrasive cleaners or scrub brushes, as they can scratch the new surface. Instead, opt for mild, non-abrasive cleaners and a soft sponge or cloth. Regularly rinse the tub after each use to prevent soap scum and mineral buildup.

Additionally, avoid allowing heavy or sharp objects to come into contact with the surface, which could cause chips or damage. It’s also important to quickly clean up any spills or stains to prevent them from setting in.

To maintain the shine and luster of your refinished steel bathtub, apply a coat of car wax every few months. This will create a protective layer and make it easier to clean. Just be sure to test the wax on a small area first to ensure it does not cause discoloration or damage.
