How to Paint a Tub or Sink

A worn-out tub or stained sink doesn’t always need replacing. With the right products and some careful prep, you can refinish porcelain, enamel, or fibreglass fixtures at home. Painting your tub or sink is a cost-effective way to make your bathroom feel new again—no demolition required.

Is It Worth It?

Yes—if:

• Your tub or sink is structurally sound (no cracks or deep gouges)
• You want a fresh, clean look without the expense of a replacement
• You’re willing to do careful prep and allow for full curing time

No—if:

• The surface is flaking or the base material is damaged
• You plan to use the fixture heavily within a couple of days (this process requires downtime)

What You’ll Need:

• Tub and tile refinishing kit (epoxy-based)
• Cleaner and degreaser or etching cleaner
• Sandpaper or abrasive pad (400–600 grit)
• Painter’s tape and drop cloths
• Small low nap roller or high-density brush
• Protective gear (gloves, mask, eye protection)
• Ventilation fan (if indoors)

Step 1:

Clean Thoroughly

Use a strong degreaser to remove all soap scum, oils, and mineral deposits. Pay special attention to corners, drains, and around faucets. Make sure to rinse thoroughly.

You may also need to use an etching cleaner if your refinishing kit includes one—this roughens the surface so the coating can bond properly.

Step 2:

Sand the Surface

Lightly sand the entire surface of the tub or sink using fine-grit sandpaper (400–600 grit) or the abrasive pad included in your kit. You’re aiming for a matte, slightly rough texture—not deep scratches.

Wipe everything clean with a damp cloth and let it dry completely. Tack with a tack cloth.

Step 3:

Tape Off Surrounding Areas

Use painter’s tape to mask around walls, faucets, fixtures, and the drain. Lay a drop cloth or plastic sheeting around the base of the tub or vanity to catch any drips.

Step 4:

Mix and Apply the Epoxy

Follow your kit’s instructions closely. Mix the epoxy components thoroughly, then apply with a low nap roller or small high-density brush.

Apply 2–3 thin, even coats. Work in smooth, overlapping strokes to avoid streaks or bubbles. Allow proper drying time between coats.

Step 5:

Let It Cure

This is the most important step—don’t rush it. Most tub refinishing kits require 48 to 72 hours of curing time before you can use the surface.

Keep the room well ventilated and avoid touching or placing anything on the surface while it cures.

Optional: Add a Clear Topcoat

Some refinishing kits include a protective topcoat to improve shine and scratch resistance. If so, apply it after the final colour coat has dried fully.
