Is your bathtub chipped, stained, or stuck in a color from the 1970s? Before you budget for a full demolition, it is worth learning how to paint a bathtub yourself. Refinishing an old tub, often called reglazing, can make a tired fixture look close to new.
The math is what makes it appealing. A DIY refinishing kit runs about $50 to $200, while a full replacement can climb past $750 once you add labor and plumbing. That gap is why the project is a favorite with budget renovators, house flippers, and landlords prepping a rental.
The catch is patience. A tub you roll paint onto in an afternoon still needs a couple of days to cure, and the finish only lasts if the prep is done right. Here is the full process, step by step.
Key Takeaways
- Use a two-part epoxy tub refinishing kit, not ordinary wall paint, so the finish can survive hot water and soap.
- Prep is about 90% of the job: strip the caulk, deep-clean the surface, then sand with 220 to 400-grit paper so the coating has something to grip.
- Ventilate hard, and skip any product that lists methylene chloride, a stripping solvent the EPA banned from most consumer uses in 2024.
- Apply thin coats and let the tub cure a full 3 days before you run water in it.
Can You Paint a Bathtub?
Yes, you can paint a bathtub, though pros usually call it “refinishing” or “reglazing.” The process itself is simple. The demanding part is not the painting; it is the deep cleaning and sanding that come first.
Skip that prep and the coating peels within months. Fresh paint needs a perfectly clean, slightly rough surface to lock onto, so most of your effort goes into creating that surface, not applying color.
Most DIYers use a refinishing kit that comes with its own brush or foam roller. Stick to the applicators the kit recommends, since a standard hardware-store roller can shed lint or leave bubbles in the finish.
Rust-Oleum makes a popular epoxy kit for jobs like this. It is a trusted brand built to handle the constant moisture of a tub or shower.
What Kind of Paint Do You Use on a Bathtub?
You cannot grab a can of latex wall paint for this. Standard paint bubbles and lifts the moment hot water hits it. To get a finish that reads as professional, you need a coating made for tubs.
Epoxy and Enamel Kits
The standard for DIY refinishing is a two-part epoxy or a specialized enamel. These cure far harder than ordinary paint, forming a shell that mimics the look and feel of porcelain.
Consider the Material
Most kits work on fiberglass, acrylic, and porcelain-enamel steel tubs. If yours is plastic or an unusual polymer, check the kit label first to confirm it is compatible.
Aerosol vs. Roll-On
You will generally choose between two application styles:
- Roll-on Kits: Easier to control with almost no overspray. Best for beginners.
- Spray Cans: They lay down a glass-smooth finish, but you must mask the entire bathroom so the mist does not settle on your vanity, toilet, and walls.
How to Prepare a Bathtub for Painting
The secret to a finish that lasts is preparation. You need to strip away years of soap scum, body oil, and cleaning residue so nothing sits between the tub and the new coating.
What You’ll Need
- Caulk removal tool or razor scraper.
- Screwdriver (for removing the drain and overflow).
- TSP (trisodium phosphate) or a heavy-duty degreaser.
- Empty bucket and sponge.
- Abrasive scouring pad.
- Acetone (for the final wipe-down).
- Epoxy putty (for filling chips).
- 220, 400, and 600-grit wet/dry sandpaper.
1. Remove Caulk and Hardware
Start by unscrewing the metal drain cover and the overflow plate. Then grab a caulk removal tool or a spackling knife and scrape out every bit of silicone caulk between the tub and the tile. Paint will not stick to silicone, so leaving any behind guarantees a peeling edge later.
2. Clean and De-Grease
Ventilation Is Key
Open every window and run the bathroom exhaust fan before you start. Cleaning chemicals and epoxy coatings give off strong fumes, and a bathroom is a small, closed room that traps them fast.
Clean the bathtub thoroughly. A degreaser like TSP cuts through built-up body oil and soap scum better than bleach, so scrub the whole surface and rinse it well with clean water. Any leftover film stops the new coating from gripping.
One safety point most guides skip: avoid any refinishing or paint-stripping product that lists methylene chloride (also sold as dichloromethane) on the label. OSHA and NIOSH have tied at least 14 bathtub-refinisher deaths since 2000 to that solvent in poorly ventilated bathrooms, and the EPA banned most consumer uses of it in 2024 (CDC). Most modern DIY epoxy kits do not contain it, but read the label before you buy.
3. Repair and Sand
If your tub has deep chips or gouges, fill them with a tub repair kit or epoxy putty and let it fully harden. Then sand the entire tub.
This step is what actually makes the paint stick. Use 220 to 400-grit sandpaper to knock the gloss off the surface, creating the fine “tooth” the coating grabs onto. Follow with 600-grit paper to even it out, then rinse the tub and let it dry completely.
Dry Time
Do not rush this. If any moisture is trapped in the surface or around the drain, the epoxy will fail. A hairdryer helps speed drying around the hardware and corners.
How to Paint a Bathtub
Once the tub is prepped, dry, and masked off, you are ready for the fun part.
What You’ll Need
- High-quality tub refinishing kit (like this kit from Ekopel).
- Painter’s tape.
- Plastic drop cloths.
- Respirator mask.
- High-density foam roller and brush.
1. Mask the Area
Run painter’s tape along the tile where it meets the tub. Cover the faucets, floor, and toilet with plastic drop cloths. Epoxy is hard to remove once it drips, so protect anything you do not want coated.
2. Mix the Epoxy
Put on a proper respirator mask. With a two-part kit, combine the hardener and base exactly as the label directs. Stir for a full two to three minutes; a well-mixed batch thickens just enough that it will not run or drip as you roll it on.
Some kits call for an “induction period,” a 5 to 10-minute rest before use, while others must go on right away. Read your specific instructions, because the working time is short once the clock starts.
3. Apply the First Coat
Start in a top corner and work down and across. Use the brush for corners and tight spots and the foam roller on the large flat areas for a smooth finish. Keep each pass thin and even so the coating does not sag.
4. Apply the Second Coat and Cure
Wait the time your kit specifies between coats, usually 1 to 2 hours, then apply the second coat for full coverage. Pull the painter’s tape while the paint is still slightly tacky so it does not peel up a dry edge.
The tub is often dry to the touch within a day, but do not be fooled: let it cure at least three full days before running water in it, and up to a week before a bath if the label says so. Rushing this is the top reason a DIY finish fails early.
Keep In Mind
Epoxy is self-leveling, which helps hide brush marks. Still, watch for sagging or “curtains” on the vertical walls of the tub and smooth them out gently with the roller before they set.
Tips For Maintaining a Painted Bathtub
A refinished tub looks great, but the new surface is softer than factory porcelain, so treat it gently:
- Skip abrasive pads (like steel wool) and harsh acidic cleaners such as bleach.
- Use a gentle, non-abrasive liquid cleaner to keep soap scum from building up.
- Do not use a suction-cup bath mat; the constant pull can lift the coating.
- Fix a leaky faucet promptly, since a steady drip slowly wears through the finish.
- Set shampoo and conditioner bottles down instead of dropping them, so you do not chip the surface.
Alternatives to Painting a Bathtub
If sanding and fumes sound like more than you want to take on, weigh these options:
- Professional Reglazing: Hire a pro to spray the coating for you, usually $300 to $650, for a finish that lasts far longer than a DIY job.
- Bathtub Liners: A custom acrylic shell that fits over your existing tub. It costs more but is very durable.
- Deep Cleaning: Sometimes a heavy-duty cleaning restores an old tub enough that it does not need paint at all.
- Recaulking: Simply re-caulking your bathtub can freshen the look with almost no effort.

In the End
Your bathtub takes a beating every day, but it does not have to look like it. Painting a bathtub is a satisfying weekend project that saves you hundreds over a replacement. The whole thing comes down to three things: scrub it truly clean, sand it well, and give the finish plenty of time to cure before the first bath.
