First, you’ll need the appropriate type of primer and paint. It is recommended that you use acrylic latex for your primer. You have two choices for your main color: Epoxy paint is the best paint you can use, but if you can’t find it in a color you like, spray paint is another option. A clear coat of epoxy will also be needed.
The first step will be to drain your toilet water, then if you wish, you can remove your toilet to bring it outside to paint. If that’s not an option or too much of a hassle, just make sure you open the windows in your bathroom and keep it well-ventilated while you paint.
Thoroughly clean your toilet to remove any residue that can mess up your paint job. The best way to do this is to spray some WD-40 on it. Let the spray sit for at least 5 to 10 minutes before you scrub it with a brush and rinse it clean to remove any stuck-on debris. You can sanitize with bleach afterward, and be sure to remove the bolts and clean every nook and cranny of your toilet or else the paint won’t stick.
