How a Cast Iron Tub can improve your Home’s Appearance


If you’re tired of looking at your old, discolored cast iron tub, you might be wondering if you can paint it. The good news is, yes, you can! In this article, we’ll go over the steps you need to take to paint your cast iron tub and give you some tips for ensuring a successful project.

Preparing Your Tub

Before you start painting, you’ll need to make sure your tub is clean and dry. First, remove any hardware or fixtures attached to the tub. Then, clean the surface of the tub with a non-abrasive cleaner and a scrub brush. Rinse the tub thoroughly with water and dry it with a clean towel.

Sanding and Priming

Next, you’ll need to sand the surface of the tub to create a rough texture that will help the paint adhere. Use 220-grit sandpaper to sand the entire surface of the tub. After sanding, wipe the tub down with a tack cloth to remove any dust. Apply a coat of primer to the tub using a paintbrush or roller. Be sure to use a primer that is specifically designed for cast iron surfaces. Allow the primer to dry completely before moving on to the next step.

Painting the Tub

Once the primer is dry, you can start painting your tub. Choose a high-quality enamel paint that is designed for use on cast iron surfaces. Apply the paint in thin, even coats, using a paintbrush or roller. Be sure to follow the manufacturer’s instructions for drying times between coats.

Finishing Touches

After you’ve applied the final coat of paint, let the tub dry completely before reinstalling any hardware or fixtures. You can also add a layer of clear coat to help protect the paint and give your tub a glossy finish.

Tips for Success

Here are a few tips to keep in mind as you paint your cast iron tub: – Be patient. Painting a cast iron tub can be a time-consuming project, but rushing it can lead to a less-than-perfect finish. – Use high-quality materials. Don’t skimp on the paint or primer – using cheap materials can lead to a less durable finish. – Take your time with sanding. Creating a rough texture on the surface of the tub is crucial for ensuring good adhesion of the paint. – Make sure the tub is completely dry before painting. Any moisture left on the surface can cause issues with the paint.


Painting a cast iron tub is a great way to give your bathroom a fresh, updated look without spending a lot of money on a new tub. With a little patience and attention to detail, you can achieve a beautiful, long-lasting finish that will make your tub look like new again.
