Refinishing a clawfoot tub can breathe new life into a vintage bathroom, save you the cost and hassle of replacing a heavy cast-iron or clawfoot unit, and add character to your space. If your tub has chipped enamel, rust, or just looks dated, refinishing it yourself is an appealing option. This is your complete DIY guide to getting the job done right.

Why Refinish a Clawfoot Tub?

• Cost savings compared to replacing the tub entirely.

• Preserve vintage or antique charm — clawfoot tubs often have craftsmanship and style that’s hard to replicate.

• Sustainability — reusing what’s already there instead of sending it to a landfill.

• Custom colors or finishes — you can update the look without losing character.

When to Refinish vs When to Replace

You should refinish if:

• The tub has mostly superficial damage: chipped enamel, rust spots, worn finish.

• It’s structurally sound — no large holes, cracks, or compromised cast-iron/fiberglass structure.

• You’re okay with the effort: sanding, dealing with fumes, careful prep.

Consider replacement if:

• The damage is extensive: large cracks, deep rust that has eaten through metal, structural issues.

• The cost and effort of refinishing begin to approach that of a new tub.

• You want a different shape or size entirely.

Step-by-Step Refinishing Guide

1. Remove Fixtures and Hardware

   Take out taps, drain covers, and overflow plates to keep them safe and ensure a clean finish.

   
   

2. Clean Thoroughly

   Scrub away soap scum, mildew, and any old caulk. A clean surface is key to adhesion.

   
   

3. Strip the Old Finish (If Necessary)

   If the finish is peeling or heavily damaged, use a stripper, scraper, or sanding tools to remove it.

   
   

4. Repair Chips, Rust, and Imperfections

   Patch chips with filler, sand rust spots down, and apply rust-inhibiting primer on bare metal.

   
   

5. Sand / Etch the Entire Surface

   Sand the whole tub to create a slightly rough surface so the new coating adheres properly.

   
   

6. Mask and Protect the Surroundings

   Tape off walls, floors, and fixtures. Lay down drop cloths and ensure good ventilation.

   
   

7. Prime if Required

   Some kits are self-priming, others need a separate primer. Apply evenly and let it dry fully.

   
   

8. Apply the Refinish / Coating

   Mix and apply the coating in thin, even layers. Expect 2–3 coats for the best finish.

   
   

9. Allow Proper Drying / Curing Time

   Let the tub cure for at least 24–72 hours before use, depending on the product.

   
   

10. Reinstall Hardware and Caulk Joints

    Once fully cured, reinstall fixtures and re-caulk joints for a polished finish.

Tips & Best Practices

• Always wear safety gear when sanding or applying coatings.

• Work in warm, dry conditions with proper airflow.

• Don’t rush between coats; follow recommended drying times.

• Use fine sandpaper between coats to smooth imperfections.

• Watch for signs of deep rust or lead paint in older tubs.

How Long Will It Last?

• A well-done DIY refinishing job can last 5–10 years with proper care.

• Avoid abrasive cleaners and harsh scrubbing to extend the life of the finish.

When DIY Might Not Be Enough

Hire a pro if:

• The tub has severe structural damage.

• Rust is widespread and deep.

• You want a flawless, glossy finish requiring specialized equipment.
