The short answer is yes — you can paint a plastic tub and shower in your mobile home. Most mobile home tubs are plastic, fiberglass, or acrylic, and most of them can be painted when prepared correctly. The difference between a paint job that lasts and one that peels within months comes down to prep work and product selection. This guide covers both.
A typical mobile home plastic tub and shower — all three surface types (plastic, fiberglass, and acrylic) can usually be painted with the right products and preparation.
Mobile home bathrooms were built to be functional, not beautiful. Most feature one-piece plastic or fiberglass tub and shower surrounds that are prone to staining, yellowing, and surface scratches over time. Rather than spending $500 to $2,000 on a replacement unit, painting your existing tub is an affordable fix that can make your bathroom look much better for under $150.
Important: Never attempt to paint a tub with structural cracks that go all the way through the surface — painting over structural damage is a temporary fix that will fail and could cause water damage under your mobile home floor. Surface chips and cosmetic cracks can be repaired and painted. True structural damage means the tub needs replacement.
Check the label first: Read the coating’s label before you buy. At least one widely sold tub and tile refinishing kit lists the surfaces it is made for (including fiberglass and acrylic) and says not to use it on flexible plastic. If your tub is thin plastic that bends noticeably when you press it, look for a product that is specifically labeled for that kind of surface. Two-part tub coatings also give off strong fumes — ventilate the bathroom well and follow the product’s safety directions.
How to Paint a Plastic Bathtub Step by Step
The actual painting takes about 30 minutes. The prep work takes 3 to 4 hours. Budget your time accordingly — rushing prep is one of the most common reasons painted tubs fail early.

Deep Clean the Entire Surface
Remove every trace of soap scum, body oils, hard water deposits, and grime. Use a non-abrasive tub cleaner to avoid scratching the plastic surface before you start. Any contamination left behind will prevent paint from bonding. Rinse completely and allow to dry for at least 2 hours — moisture under paint causes immediate failure.
Sand the Entire Surface
Use 400-grit wet/dry sandpaper and sand in circular motions across every inch of the tub surface. You are creating micro-scratches that give the coating something to grip. Paint will not bond long-term to an unsanded plastic surface regardless of product quality. Wipe away all dust with a damp cloth when finished and allow to dry completely.
Prime If Your Paint Calls for It
Follow your tub paint’s instructions on primer. If it calls for one, use a primer made for plastic or fiberglass — standard primers won’t bond to plastic and the paint will peel. Some two-part tub and tile kits are applied directly to a properly cleaned and sanded surface with no separate primer. Allow any primer to dry fully according to its label before painting.
Apply Paint in Thin Even Coats
Apply your tub paint in thin even coats. Two to three thin coats will always outperform one thick coat. Thick coats trap air bubbles, take longer to cure, and are far more likely to peel. Allow each coat to dry fully before applying the next — follow the manufacturer recommended dry time exactly.
Wait the Full Cure Time Before Use
This is where a lot of people ruin an otherwise good paint job. The paint may feel dry to the touch within hours, but it needs days to cure before it can handle water. One common tub and tile kit, for example, says to wait 3 days before exposing it to water. Follow your product’s label, and don’t use the tub, run water in it, or allow any moisture contact until that time has passed.
Tip: Plan around the wait. If your product needs 3 days and you paint on a Thursday evening, the tub won’t be ready until Sunday evening, so line up another place to shower.

What Paint to Use on a Plastic Bathtub
Choosing the wrong paint is a common mistake on this project. Not all paints bond to plastic — using standard wall paint or general purpose paint will result in peeling within weeks regardless of how well you prep. Here are your three options ranked by durability:
Epoxy Paint
The most durable choice for painting plastic tubs. Chemical resistant and designed for constant wet environments. Comes as a two-part system requiring mixing before application. Costs about $80–$100 and is generally the longest-lasting DIY option.
Acrylic Paint
Budget-friendly option that is easier to apply and dries faster than epoxy. Available in more colors. Runs approximately $65–$80. Generally not as durable as epoxy, so expect touch-ups sooner. Must be specifically rated for tub and shower use — not standard acrylic craft paint.
Spray Paint
Most convenient to apply but least durable option for a full refinish. Best for small touch-ups and chips rather than a complete redo. Must specifically say it bonds to plastic and is moisture resistant. Not recommended as a complete refinishing solution.

See Repair Kit on AmazonHow Do I Tell If My Tub Is Fiberglass or Acrylic?
It helps to know because some coatings list which materials they’re made for. None of these checks is perfect on its own, so use them together:
The Look and Feel Test
Acrylic usually has a smooth, glossy, even finish and feels fairly rigid. Fiberglass with a gelcoat finish is usually less glossy, often looks dull or chalky with age, and tends to give more when you press firmly on the sidewall.
The Chip Test
Look at a chip or an exposed edge. Fiberglass has a thin colored gelcoat skin over a fibrous layer. Acrylic has a thicker layer of solid-color acrylic. Many acrylic tubs are also reinforced with fiberglass on the back, so the underside alone won’t tell you.
The Paperwork Test
Look for a manufacturer label or model number on the tub, the access panel, or the home’s paperwork, and look it up. That’s the most reliable way to know what you have.
Good to Know: If you can’t tell which material you have, pick a coating whose label lists plastic, fiberglass and acrylic, and follow its prep steps exactly.
Can I Paint a Fiberglass Tub?
Yes — fiberglass tubs can be painted and the results can look nearly new. The process is almost identical to painting plastic with a few key differences:
A badly stained fiberglass shower unit — fiberglass tubs and showers can be completely transformed with the right two-part epoxy paint and proper preparation.
Sand Until the Whole Surface Is Uniformly Dull
Older fiberglass gelcoat is often chalky or pitted. Sand every bit of the gloss off so the coating has something to grip, using the grit your product calls for. One common tub and tile kit, for example, calls for 400–600 grit wet/dry sandpaper.
Use Epoxy Paint Rated for Fiberglass
Make sure your paint is specifically rated for fiberglass surfaces — not just plastic. A quality two-part epoxy labeled for both plastic and fiberglass is your best choice.
Apply at Least Two Full Coats
Most tub coating kits call for at least two coats for complete coverage and a uniform finish. Follow the recoat time on the label.
Allow the Full Cure Time
Wait the full cure time on the label (often about 3 days) before any water contact.
Can I Paint a Plastic Bath Panel?
Yes — and it is actually easier than painting the tub itself. Plastic bath panels take paint well because they are not exposed to the same constant water contact as the tub floor and walls. Use the same basic process — clean, sand, prime if your product calls for it, and paint. Bath panels are a good place to start if you want to practice the technique before tackling the main tub surface.
Good Starting Point: If you have never painted a plastic surface before, start on the side bath panels to get a feel for the product and application before moving to the tub interior where technique matters most.
How Long Will a Painted Tub Last?
A painted tub won’t last as long as a new one, but a properly prepared and painted tub can hold up for years with normal household use. How long yours lasts depends on four main factors:
| Factor | Impact on Lifespan | What to Do |
|---|---|---|
| Prep Quality | The single biggest factor — poor prep means early peeling regardless of paint quality | Never skip or rush cleaning, sanding, or priming |
| Paint Type | Two-part epoxy generally outlasts one-part tub paint, which outlasts spray paint | Use two-part epoxy for maximum lifespan |
| Cure Time | Using the tub too soon is another common reason for early paint failure | Wait the full cure time on the label — no exceptions |
| Cleaning Habits | Harsh scrubbing pads will scratch and chip the finish quickly | Use non-abrasive cleaners only after painting |
Cost Comparison: DIY tub painting costs $100–$165. Professional refinishing costs $300–$600. Full tub replacement costs $500–$2,000 installed. For a structurally sound tub, DIY painting is the lowest-cost way to refresh the finish.
How to Fix Cracks and Chips Before Painting
If your tub has surface chips, scratches, or cosmetic cracks — fix those before you paint. Painting over unrepaired damage will cause the paint to crack and peel in those exact spots within weeks of completion no matter how well everything else is done.
Clean the Damaged Area
Wash the cracked or chipped area with soap and water. Allow to dry completely — any moisture in the repair area will prevent proper adhesion of the repair compound.
Sand Around the Damage
Lightly sand the area around the crack or chip to create a bonding surface for the repair material. Feather the edges so the repair will blend smoothly into the surrounding surface.
Apply the Repair Compound
Use a tub and shower epoxy repair kit — mix according to instructions and fill the damaged area completely, slightly overfilling to allow for sanding flush. Works on plastic, fiberglass, and acrylic surfaces.
Sand Smooth and Paint
Once the repair compound has fully cured (typically 24 hours), sand it smooth and flush with the surrounding surface. Then proceed with your normal cleaning, sanding, priming, and painting process.
Painting a Plastic Shower
The same process applies to plastic shower walls and surrounds. Showers are slightly more challenging than tubs because of constant water and steam exposure — but paintable with the right approach. Here are additional tips specific to shower areas:
Before and after of a mobile home plastic shower unit — the change from stained and yellowed to clean and fresh is achievable with the right tub paint and proper preparation.
Pay Extra Attention to Corners
Grout lines, caulk seams, and corners collect the most soap scum and mildew. Spend extra time cleaning these areas — contamination here is a common cause of shower paint failure.
Tape All Fixtures
Use quality painter’s tape on all fixtures, faucet handles, shower heads, and hardware before painting. Remove tape carefully before the paint fully dries to prevent peeling at the edges.
Kill Mildew First
Clean any mildew completely and let the surface dry before you sand. If your product calls for a primer, use the one it specifies. Don’t add a layer the coating’s instructions don’t mention.
Shower Tip: Only add a clear topcoat if the paint maker sells or approves one for that product. Mixing coatings that aren’t made to work together can cause peeling.

Would You Rather Sell Than Repair?
Painting a tub makes sense when it’s a surface problem. If the tub is just one item on a long list — soft floors, plumbing leaks, roof work — selling the home as-is is one option to compare. I buy mobile homes that need work, and you don’t have to fix anything first.
Frequently Asked Questions
What is the best paint for plastic shower walls?
The best paint for plastic shower walls is a two-part epoxy paint specifically formulated for tubs and showers. It bonds well to a properly sanded surface and stands up to moisture and daily cleaning. Look for products that specifically say “tub and shower” on the label — general purpose or wall paint will not hold up in a wet environment.
Can plastic shower walls be painted?
Yes — plastic shower walls take paint well when properly cleaned, sanded, and primed if the product calls for it. Use an epoxy or acrylic paint specifically rated for wet areas and allow the full cure time on the label (often about 3 days) before use. The walls are actually easier to paint than the tub floor because they are vertical and see less direct water contact.
What paint do you use on a plastic bath?
Use acrylic or epoxy paint designed specifically for plastic tub and shower surfaces. Standard wall paint, latex paint, and general purpose acrylic craft paint will not adhere to plastic in a wet environment and will peel within weeks. Always check the label for plastic compatibility and tub/shower rating before purchasing.
Can you paint an acrylic tub and shower?
Yes — acrylic tubs and showers can be painted and the results can look nearly new at a fraction of replacement cost. Use a paint specifically rated for acrylic surfaces, prepare the surface thoroughly with cleaning and sanding, prime if the product calls for it, and allow full cure time. Check that the product lists acrylic as an approved surface.
What kind of paint will stick to a plastic tub?
For plastic tub surfaces in a wet environment you need an epoxy or acrylic paint specifically rated for tub and shower use. The key is always surface preparation — clean, sand, and prime if the product calls for it. That sequence is what makes paint stick long term on any plastic surface, regardless of brand or product.
How long will a painted tub last?
A properly prepared and painted tub can last for years with normal use, though not as long as a new tub. Two-part epoxy generally lasts longer than one-part paint. Waiting the full cure time before use helps extend the lifespan. Use only non-abrasive cleaners on painted surfaces going forward — harsh scrubbing pads will scratch and dull the finish prematurely.
How do I know if my mobile home tub is plastic or fiberglass?
Acrylic is usually glossy, smooth and fairly rigid. Fiberglass gelcoat is usually less glossy, can look chalky with age, and tends to flex more when you press on it. At a chip, fiberglass shows a thin colored skin over a fibrous layer, while acrylic has a thicker solid-color layer. A manufacturer label or model number is the surest answer. Some mobile home tubs are thin molded plastic instead — if yours bends easily, check that your coating is approved for that surface.
Is it worth painting a tub or should I just replace it?
Painting is usually worth it if the tub is structurally sound — no cracks that go all the way through the surface. DIY painting costs $100 to $165 versus $500 to $2,000 for replacement. If the tub has structural cracks, severe staining that has penetrated the surface, or extensive mold damage below the surface, replacement makes more sense than painting.
