If you're tired of your old sink with stains and scratches, but not tired enough to buy a new one, restoring and painting your sink can be an option. Yes, you can paint a bathroom sink. However, the regular paint won't work, so if you don't want it to peel off in a week, it is important to do it properly.

The benefit of painting your sink is simple - you get a refreshed, restored sink. However, it is also an opportunity to try new colors or to base your entire bathroom's look around an improved sink. The trend in 2026 shifted toward earthy and organic hues, so clay or olive green are definitely tones to try.

Materials

High-quality materials are essential in sink restoration. They should look good and withstand constant water and chemical exposure. The usual option is to use special epoxy refinishing kits. However, acrylic sinks require a special bonding primer to work with these kits.

It is important to consult with a professional renovator to find out the perfect combination for your sink.

Safety tip: Use a professional respirator. A simple dust mask won't be enough to filter the fumes. Also, place a window fan to pull the fumes out of the house.

Preparation

Another important step is to get your sink ready for the renovation. It includes deep cleaning and sanding with sandpaper. The better you do it, the better the new epoxy will adhere. After initial preparation, complete drying is necessary. It is a crucial step, as even one tiny drop of water under the epoxy can compromise its integrity.

Cure Time

After applying the epoxy, it is important to let it sit for a couple of days. This cure time will ensure that the material is hardened and ready to use. The recommended room temperature for this process is about 24°C (75°F). 10 degrees below that, and cure time can literally double. High humidity can also make cure time longer. Usually, it takes about 4 days, but it depends on temperature and humidity.

To check if it’s done, use your sense of smell. If it smells chemically or like paint, it is not fully cured.

Aftercare

The painted sink does not have the same durable qualities as a manufactured sink. Because of that, hard abrasives, acidic cleaners, or vigorous scrubbing can affect the integrity of the epoxy and result in peeling. It is better to use mild chemicals and soft cloths instead of harsh solutions and hard abrasives.

It is important to be careful at every step of painting a sink, but a successful project will result in a beautifully renovated sink that lasts a long time.
