Using the right type of paint in a shower is crucial for protecting the surface from moisture damage. Enamel paint is one option commonly used for painting showers, but there are a few things to consider before using it.

What is Enamel Paint?
Enamel paint, also known as gloss paint, has a glossy, smooth finish once dry. It is made from acrylic or alkyd resins mixed with solvents and pigment. The paint cures to form a plastic-like coating that is durable, scratch-resistant, and washable.
There are two main types of enamel paint:
- Oil-based enamel – Made with alkyd resins suspended in solvent
- Latex or acrylic enamel – Made with acrylic resins suspended in water
Oil-based enamels provide a glossier, more durable finish but contain strong solvents like mineral spirits that can be hazardous to work with. Latex enamel is lower odor and lower VOC but may not be as hard or glossy as oil-based.
Benefits of Using Enamel Paint in Showers
Here are some of the benefits that make enamel a good choice for painting showers:
- Moisture resistance – Enamel paint creates a non-porous coating that repels water and moisture. This prevents swelling, peeling, and growth of mold and mildew.
- Washability – The slick finish allows grime, soap scum, and dirt to be cleaned off easily using mild cleaners.
- Durability – Enamel is highly scratch, chip, and stain resistant compared to flat paints.
- Appearance – The glossy finish gives a bright, fresh look and can make a small shower appear larger.
Using Latex vs. Oil-Based Enamel
For painting showers, latex enamel is the preferred choice over oil-based:
| Latex Enamel | Oil-Based Enamel |
|---|---|
| Water-based so lower odor and VOC | Contains solvents that have strong odor |
| Cleans up with water | Require paint thinner for cleanup |
| Less shiny than oil-based | High-gloss finish |
| More prone to scratching | More durable and scratch-resistant |
The low odor and cleanup of latex enamel makes it more user-friendly. The finish may not be quite as durable as oil-based, but it still provides good moisture resistance and washability.
Preparing and Painting the Shower
Proper prep work and painting technique is important when using enamel in moist environments:
- Clean surfaces – Use TSP substitute to remove any dirt, oils, soap scum, and mildew.
- Sand glossy surfaces – For maximum adhesion, scuff sand tile and fiberglass with fine sandpaper.
- Prime – Use a stain-blocking primer made for bathrooms.
- Apply two coats – Allow proper drying time between coats.
- Ventilate – When using latex enamel, allow proper ventilation while painting.
- Let cure fully – Wait 1-2 weeks before exposing to moisture.
Paying attention to preparation and application techniques will give the enamel paint the best chance of adhering well and providing long-lasting protection.
Maintaining the Painted Shower
To keep enamel shower paint looking fresh, follow these maintenance tips:
- Avoid abrasive cleaners which can damage the finish over time.
- Use a squeegee after showering to prevent mineral deposits.
- Clean with a gentle cleaner like dish soap and water.
- Recaulk around fixtures when needed to prevent moisture access.
- Watch for any cracks or flaws forming in the surface and touch up quickly.
- Consider recoating every 2-3 years in high use showers.
Conclusion
Enamel paint can be an excellent choice for painting showers when proper preparation and application is followed. Latex enamel provides good moisture resistance and ease of use compared to oil-based options. Maintaining the shower finish with gentle cleaning and touch ups will keep the enamel looking like new. An enamel painted shower can provide a fresh, waterproof new look with just a couple coats of paint.
