Though bathtubs are made from durable glazes, after years of being subjected to hard water, abrasive soaps, dirt and oils, and the occasional dropped shampoo bottle or shaving cream can, they can begin to accumulate stains and chips that turn the tub into a bathroom eyesore.
While the cost of replacing a tub may not be in the budget, there are DIY tub refinishing kits that can return the tub to a like-new appearance in just a few hours. These kits include strong epoxies and enamels that one can apply with a paintbrush, a roller, or an aerosol spray can to porcelain, metal, and fiberglass tubs.
This guide will explore what factors are important to consider when selecting the best tub refinishing kit while reviewing some of the top products on the market.

What to Consider When Choosing the Best Tub Refinishing Kit
Most bathtub refinishing kits are compatible with the most common bathtub materials, but it’s also essential to consider how each product is applied, how much coverage they provide, and what supplies are included with the kit. Ahead, learn more about these and other important characteristics of tub refinishing kits.
Bathtub refinishing kits are versatile. Most are capable of working with the most common bathtub materials, including cast iron, porcelain over metal, fiberglass, and acrylic.
- Cast iron: Cast-iron tubs consist of a metal form coated with a thick layer of enamel. The enamel resists scratches and chips, making it one of the more durable tub types.
- Porcelain over metal: Porcelain over metal tubs consist of a thick coating of porcelain on steel, which gives it strength. Porcelain can chip easily, revealing the dark metal underneath it. Over time, the porcelain coating can also become stained and dull.
- Fiberglass: Fiberglass is a cheaper plastic material that is more durable than porcelain and porcelain over metal tubs. While fiberglass will not chip like porcelain on metal tubs, it can crack and fade over time.
- Acrylic: Acrylic tubs are similar in look and feel to fiberglass and are relatively easy to repair. They consist of acrylic over supporting fiberglass sheets. Like fiberglass, they are susceptible to fading and cracking over time.
White is the most common and popular option for bathtubs, although other colors are available to suit different styles. Many refinishers are tintable, allowing the user to change the color by adding acrylic paint. Some kits even include tinting dyes that allow the user to match the refinisher to the existing tub if it’s for a repair, or create a color of their choice if it’s a total refinish job. Most refinishers dry to a high-gloss smooth texture that mimics porcelain; however, some have a sand additive that gives the finish a slightly rough, nonslip texture.
Coverage and Thickness
Paying attention to the coverage the product offers is key to achieving good results. Since these products typically have strict drying times, there won’t be any leeway to run to the store for another kit should one run out mid-refinishing.
Most refinishing kits provide enough coverage to apply two coats to a standard-size bathtub.
If the tub has a significant amount of wear, it may need three coats to return it to its former glory, in which case it may be necessary to purchase additional resurfacer. Some larger kits include enough resurfaces to cover a bathtub and a tub surround.
Thickness also impacts coverage. Two-part pour-on enamels and epoxies are thicker than refinishers that come in an aerosol spray can. As such, a pour-on refinisher may only require a single coat to refinish the tub whereas a spray refinisher may require as many as three coats.
Many refinishing kits include all the supplies needed to complete the refinishing project. Typical supplies included in these kits are tack rags, stir sticks, etching cleaners, foam rollers, sandpaper, and rubber gloves. That said, not all bathtub refinishers come fully equipped with supplies. Check to see what supplies the kit includes and what will need to be purchased separately to complete the job. Looking to do a larger bathroom refresh? Just know that painting bathroom tile usually requires different materials than those found in tub refinishing kits.
Ease of Application
Spray-on bathtub refinishers come in aerosol spray cans, while pour-on refinishers are packaged similarly to paint or epoxy. Refinishers that come in aerosol cans are easiest to apply as they require very few additional supplies. Once the tub has been prepped and taped off, simply spray the tub from a distance of about 12 inches using even back-and-forth strokes to get a uniform coating. Since spray refinishers go on in a thin coat, they typically require two or three applications for best results.
Pour-on refinishers are more labor intensive and require a bit more skill as the user must pour the material around the rim of the tub, then distribute it with a brush or a foam roller. While single-step refinishers are ready to use out of the can, two-step epoxy coatings require the user to mix the hardener and the resin just prior to application. The user must also work quickly when using a pour-on resurfacer to prevent the product from setting up before the application is done. Although pour-on resurfacers are more work, they typically produce better results and often require only a single coat.
While tub refinishing kits will dry to the touch rather quickly—some spray-on products dry in as little as 20 minutes—the user must typically wait longer before using the bathtub. The wait time before reopening the bath depends on the product and can be as little as 24 hours or as long as 3 days. Most manufacturers list the resurfacer’s total cure time on the packaging. Remember, it’s always best to err on the side of caution when deciding when to use the bath, as exposing a refinisher that hasn’t fully dried to water can ruin the new coating.
In order to create a durable coating that can withstand the rigors that a tub faces, most tub refinishing kits include strong solvents in their ingredients, many of which put off harsh fumes and high VOCs. With that in mind, it’s wise to ventilate the space while applying the resurfacer by setting up fans, turning on the bathroom fan, and opening windows. There are some products that are odorless during application and put off low VOCs, making them ideal for resurfacing projects in bathrooms that lack windows for ventilation.
Tips for Using a Tub Refinishing Kit
Refinishing a bathtub is a job most DIYers can handle, though there are a few tips and tricks to getting the best results and ensuring the new coating lasts many years. Properly preparing the tub, evenly applying each coat, and giving the new coating plenty of time to cure are all key to achieving good results.
- Don’t cut corners when prepping the tub. How long a tub refinishing kit lasts is directly related to how well the product adheres to the tub’s existing finish. So while cleaning and sanding the tub may seem tedious, it’s critical to creating a surface that will adhere well to the refinisher.
- Apply evenly. Even though most refinishers are self-leveling, it’s still important to get as even a coat as possible, whether using a brush, roller, or spray can, to prevent inconsistencies in the paint.
- Remove the tub drain and overflow faceplate. If possible, remove the tub drain and the faceplate covering the overflow. This will allow you to coat under these areas, eliminating a seam between the new coating and old coating around the drain and faceplate that could promote chipping or peeling.
- Let it cure. The sight of a refinished tub may make you anxious to use it, but subjecting the new finish to water too soon will shorten the life of the new glaze. Err on the side of caution and wait a few days for the glaze to harden.
