How to Paint a Bathtub: A Step-by-Step Guide

First, can you actually paint a bathtub? We get this question a lot, and the answer is—yes, you can paint a bathtub. Whether you should depends on a few things (which we’ll get into), but let’s be clear right off the top: this isn’t your average slap-on-a-bit-of-gloss-DIY. Painting a bathtub is one of those oddly satisfying jobs where patience and precision really pay off.

Maybe your tub’s lost its sparkle. Maybe it’s avocado green and you’ve finally had enough. Either way, painting your bath can be a surprisingly cost-effective way to bring it back to life—without tearing up the entire bathroom.

What Types Of Bathtubs Can Be Painted?

Here’s where things get a little technical. Not all tubs take well to paint. Most commonly, you’re dealing with one of the following:

Porcelain-Coated Cast Iron Or Steel

These can be painted, but it takes a bit of elbow grease. You’ll need to thoroughly sand the surface to help the new coating stick. And no, you can’t skip this part.

Acrylic Bathtubs

Acrylic tubs are generally paintable, but be cautious. Some acrylic finishes may resist adhesion even with primers. Always check the manufacturer's info—or test a small spot first.

Fibreglass

Also doable. Though you might need a special bonding agent or epoxy-based paint to make sure it lasts. (Peeling paint in the bath? Not ideal.)

If you’re not sure what type of tub you have, we think it’s worth checking before you get too invested in the process. Saves a lot of heartache later on.

What Kind Of Paint Do You Use On A Bathtub?

Let’s cut to the chase: regular wall paint won’t cut it. Your bathtub needs something tougher, more durable, and definitely waterproof.

The best option? Epoxy-based paint—specifically formulated for bathrooms. It can take the heat, resist moisture, and stand up to daily use. (Plus it tends to leave a smoother, cleaner finish if you do it right.)

There are also tub and tile refinishing kits available, which include everything you’ll need from cleaner to top coat. Handy if you’re new to this kind of thing.

How To Prep Your Bathtub Before Painting

Don’t rush this bit. Preparation might not be the most exciting part of a DIY job, but it’s easily the most important.

Clean It Like You’ve Never Cleaned Before

We’re talking a deep clean. Scrub off every last bit of soap scum, mould, grime—whatever’s on there, it has to go. Use a heavy-duty cleaner and rinse thoroughly.

Sand The Surface

Yes, even if it looks smooth. Sanding creates a rough texture that helps the paint stick. A fine-grit sandpaper should do the trick. And don’t forget to wipe away the dust afterwards.

Repair Any Chips Or Cracks

Tiny cracks might not seem like a big deal, but they’ll show through the paint—and worse, they might compromise how well the paint holds up. Use a filler suitable for your tub material.

Mask Off Surrounding Areas

Unless you’re going for the “accidentally painted the tiles too” look, use painter’s tape to protect taps, edges, and walls.

Painting Your Bathtub: The Fun Part (Sort Of)

Here’s where things get a little zen. Or messy. Possibly both.

Mix And Apply Your Epoxy Paint

Follow the kit instructions to the letter—some epoxy paints come in two parts that need to be mixed. Then, using a high-quality brush or foam roller, apply your first coat in even, deliberate strokes. Watch for drips.

Wait. Then Paint Again

Most paints will need at least two coats. Some need three. Don’t rush it—follow the drying times religiously. The longer you leave between coats, the better the finish tends to be.

Let It Cure (This Is The Hard Part)

Curing takes time. Anywhere from 24 hours to a few days, depending on the product. Avoid the temptation to jump in for a test soak. The finish will be stronger if you wait.

Will A Painted Bathtub Actually Last?

Here’s the honest bit: a painted bathtub won’t last forever. But it can hold up for several years if it’s done properly.

Avoid abrasive cleaners, steer clear of bathmats with suction cups (they can pull the paint right off), and be gentle. That said, for a fresh new look without replacing the whole tub? Worth it.

And if you’re going all out for a bathroom upgrade, don’t forget the rest of the design—things like clean lines for modern bath styling can really tie everything together.

Is Painting Better Than Replacing?

We’re not going to pretend painting is better in every situation. If your tub’s structurally damaged, leaking, or you just fancy something bigger and more luxurious—it might be time to look at full replacement.

But if you’re happy with the shape and size, and it’s just the look that’s bothering you? Painting’s a great shout.

Final Thoughts

So—can you paint a bathtub? Absolutely. Should you? That’s up to you, but if your current tub is sound and you're just craving a new aesthetic, it’s a project well worth considering.

Take your time, follow the steps, and prep like a pro. The result can be surprisingly satisfying (and let’s be honest—far more budget-friendly than a full remodel).

Just don’t forget to let it cure. Seriously.
