How to Paint a Bathroom Vanity | Step-by-Step
Your bathroom vanity takes a beating every single day. Water, steam, and daily use leave it looking worn and dated. The good news? You don’t need to spend thousands on a replacement. A fresh coat of paint can make it look brand new, and you can do it yourself over a weekend. Learning how to paint a bathroom vanity is easier than most people think. With the right prep work, the right products, and a little patience, you’ll get a finish that holds up for years. This guide walks you through every single step, from removing the hardware all the way to reinstalling the doors. Why Paint a Bathroom Vanity Instead of Replacing It A new vanity costs anywhere from $300 to $2,000 or more, and that’s before installation. Painting a bathroom vanity cabinet runs about $50 to $150 in materials. That’s a massive difference. Beyond cost, painting gives you total control over the color and finish. Want matte navy? Done. A warm white that matches your tile? Easy. You’re not stuck choosing from whatever the store has in stock. There’s also the environmental side. Replacing a functional vanity sends perfectly good wood or MDF to a landfill. Painting it gives it a second life. Here are the main reasons homeowners choose to paint instead of replace: Cost savings of 80% or more compared to replacement Complete control over color and finish Project typically done in one weekend No need to hire a contractor Less waste and disruption to your home Tools and Materials You’ll Need Getting the right supplies before you start makes a big difference. Don’t try to skip the primer or grab a cheap brush. The prep and materials are what separate a professional-looking painted bath vanity from a messy one that chips in six months. Tools Screwdrivers (flathead and Phillips) Sanding block or orbital sander 120-grit and 220-grit sandpaper Tack cloth or microfiber cloths Painter’s tape Drop cloth or plastic sheeting High-density foam roller (4-inch) Angled synthetic bristle brush (2-inch) Small container for paint Putty knife Materials TSP substitute cleaner or degreaser Wood filler or spackling compound Bonding primer (shellac-based or oil-based) Cabinet or trim paint (latex or alkyd) Clear topcoat or polyurethane (optional but recommended) Mineral spirits or paint thinner (if using oil-based products) Quick tip: For a painted bathroom vanity cabinet, always choose a paint labeled for cabinets or trim. Regular wall paint is too soft and will scratch easily in high-moisture areas. Preparing the Bathroom Vanity This is where most DIYers cut corners, and it always shows later. Good prep work is the foundation of a finish that actually lasts. Remove Doors, Drawers, and Hardware Take off all cabinet doors and drawer fronts. Remove hinges, knobs, and pulls. Label everything with painter’s tape and a marker so you know exactly what goes where during reassembly. Lay the doors flat on your drop cloth in a well-ventilated space. Painting them flat prevents drips and gives you a much smoother finish. Set Up Your Work Area Cover the floor, sink, and countertop with plastic sheeting. Use painter’s tape to protect the wall edges, mirror frame, and any hardware you can’t remove. Good masking saves you an enormous amount of cleanup later. Cleaning and Sanding the Surface A clean surface is a must. Any grease, soap residue, or grime will prevent the primer from sticking properly. Mix TSP substitute with warm water and scrub every surface you plan to paint. Pay special attention to around the handles and near the sink where buildup is worst. Rinse with clean water and let everything dry completely, at least an hour. Once dry, sand the entire surface with 120-grit sandpaper. You’re not trying to strip the finish. You just want to scuff it up so the primer has something to grip. Sand with the grain on wood. On MDF or laminate, use light circular motions. After sanding, wipe everything down with a tack cloth. This removes the fine dust that would otherwise get trapped under your paint and create a bumpy, rough finish. Don’t skip this step. Repairing and Filling Imperfections Now that the surface is clean and scuffed, take a close look at it. Look for dings, gouges, old hardware holes you’re not using, or any cracks. Fill these with wood filler or spackling compound using a putty knife. Apply a small amount, press it in firmly, and scrape off the excess. Let it dry completely per the product label directions. Once dry, sand those filled spots smooth with 120-grit, then finish with 220-grit for a seamless surface. Wipe with a tack cloth again before moving to the primer. Priming the Vanity Do not skip the primer. This is probably the single most important step when painting a bathroom vanity. In a high-humidity environment like a bathroom, standard paints will peel without a strong bonding base. Use a shellac-based primer like Zinsser BIN or an oil-based bonding primer for the best adhesion on wood, MDF, or laminate surfaces. Apply the primer with a foam roller on flat surfaces and a brush on edges and details. Work in thin, even coats. One coat of primer is usually enough, but if you’re painting over a dark stain or raw MDF, two coats gives better coverage and block-out. Let the primer dry fully. Check the label, but most need at least an hour before sanding. Once dry, lightly sand with 220-grit sandpaper to knock down any bubbles or brush marks. Wipe with a tack cloth. Choosing the Right Paint The paint you choose matters as much as the prep work when you’re painting bathroom vanity cabinets. You
