Can You Paint The Shell Of A Hot Tub?

Can You Paint The Shell Of A Hot Tub?

A hot tub shell made from polyester vinyl is a thin layer of flexible material that covers the inner tub of a hot tub.

The polyester vinyl is typically installed over an in-built water cushion and PVC sheeting.

This type of shell provides strength and rigidity to the structure, and you can find it in baths or Spas across the world.

The shell is usually on the inside of the hot tub to provide extra protection for the water. The water cushion comprises a high-density foam covered by the shell.

When a person enters a hot tub or Spa, they get exposed to either: a) direct radiant heat from some heating device or b) indirect radiant heat, where you only expose them to warm air temperatures and no direct heat.

The hot tub will typically have a mechanism to control and maintain the temperature of the water.

Yes. It give it the look of marble, fiberglass, iron, and so many more. Painting the shell of a hot tub is an economical and easy way to give your tub an updated look and provide it with protection from external elements that can affect a hot tub if not adequately maintained.

Painting your hot tub saves you time and money while giving your hot tub an updated look that is attractive to your guests.

“The Old Fashioned Way”

The easiest way to paint the shell of a hot tub is the “old-fashioned way.” Here is how you can do this:

1.) Get all the necessary items for masking, sanding, and painting, including paint, rags, and brushes.

2.) Remove the lid and seats, prop them up against a fence or secure them with pins.

3.) Make sure all the hot tub components are immobile before painting.

4.) Use masking tape and cover the hot tub components that you do not want to get paint on.

5.) Sand down any rough spots or areas where paint has already chipped off.

6.) Paint the shell of your hot tub with high-quality exterior-grade polyurethane paint.

7.) Let the paint dry thoroughly and remove the tape.

8.) Clean off any dust, dirt, or debris with a damp cloth.

9.) Re-install all your hot tub components, then re-complete the steps listed above.

(If you have a sauna, steam room, or any other hot tub features you want to paint with, this method of painting would not work.

It would need additional steps to mask these features, so they do not get paint on them. This method does not work for fiberglass hot tubs. All fiberglass hot tubs need a different process to paint them.)

This method provides easy-to-follow instructions written in plain English that your grandmother could follow.

It’s the easiest way of painting a hot tub shell, and someone who does not know what they are talking about cannot write the steps.

This method works very well and gives you almost guaranteed results every time.

Can You Paint Hot Tub Panels?

Yes. You can paint hot tub panels, but to avoid painting the cabinet, I recommend applying a protective coating like a clear or white vinyl sealer to the door, paneling, and cabinet before painting.

If you are refinishing your hot tub or want to paint a different color from what is currently in your hot tub, you can use Rust-Oleum’s Solid Color Wheel Spray Paint, which comes in over 50 colors.

I recommend two light coats for any new paint job application.

If you want to refresh the tub’s look and have it match your current decor, you can repaint your hot tub cover with Valspar’s enamel paint.

This is a much easier process than redoing the entire hot tub.

You can also use Valspar’s High Heat Enamel spray paint for hot tub panels and their high heat spray paint on the interior of your hot tub.

If you use the tub during the painting process, I recommend two to three coats and allow each coat to dry for at least 24 hours before use.

Can You Change The Color Of Your Hot Tub?

Yes. You can change your hot tub’s color by adding color-changing filters to your heating system.

These filters will change the hue of the water to match a particular color you choose, from blue to green and everything in between.

The process is straightforward, and many manufacturers offer solutions such as SmartVu filtration systems if you’re looking for something a little more flexible.

These systems are versatile and can change colors, from “cold” pastel shades to the more traditional “hot tub” colors.

The best thing about SmartVu is that it’s a direct replacement for the filter you’re currently using, allowing you to change your watercolor with the correct replacement filter easily.

Indeed, there are a few things to keep in mind when attempting to change color.

First, the filters will only work if you expose them to light, so you’ll need to leave the cover off your hot tub and position it directly in sunlight (or near a bright light).

Second, some colors look better than others. For example, a blue-ish tint will make the water look green, while a green tint will have a blue appearance.

How Do You Paint The Outside Of A Hot Tub?

There are plenty of creative and inexpensive ways to paint the exterior of your hot tub so that it matches any space and never looks out-of-date.

The best thing is that painting will save you money in the long run by making your hot tub more energy efficient.

The next best thing is that you’re going to be able to turn a not-so-attractive, out-of-place hot tub into an attractive, stylish hot tub with these quick and inexpensive painting tips.

Step 1: Find the Perfect Paint Color

The first thing you need to do is decide what color you want. The easiest way you can do this is by determining what color you want the inside of your hot tub to be.

Take into consideration any other furniture you might add to the space, such as barstools, tables, and chairs.

If you’re planning on having a full hot tub bar, consider whether you want the hot tub to blend in with the room or stand out from it.

Once you’ve decided on the interior color, you can use that as a guideline when deciding on the exterior paint.

Pick the color that will work well with your interior, then customize it.

For example, if your hot tub is white and will have wooden furniture, pick a white to give the hot tub that warm feel.

The more vivid color you choose, the more vibrant it will be against your wood furniture.

Step 2: Prepare Your Hot Tub

You need to prep your hot tub before you paint. This is important because it won’t dry properly if you paint the hot tub without prepping it.

The moisture and elements will cause the paint to peel prematurely. If your hot tub has an acrylic interior, clean it to remove any oils or residues before you apply paint.

You don’t want to end up with a slick, slick surface.

Step 3: Sand the Outside of your Tub

Sand the hot tub to get a smooth finish on the paint. You can use an electric sander or an orbital sander designed explicitly. Use 100-grit sandpaper on all sides of the hot tub.

If it’s not smooth enough, go over it with 220 grit until you’re satisfied.

Step 4: Stain the Outside of Your Tub

Stain the outside of your tub after sanding it. You can use any stain type, but do not use a polyurethane stain.

UV rays and sunlight will cause the polyurethane to deteriorate and dry out much faster than others, making your hot tub and furniture vulnerable to damage.

Instead, opt for one of the other stains available and add a clear coat over the finish to protect it from fading or chipping.

Step 5: Paint the Outside of Your Tub

The best way to paint the outside of your hot tub is with spray foam—no need to use a roller for this task. The spray foam will give you a smooth surface and even distribution.

Spray four coats of high-quality spray foam over the entire hot tub, allowing each coat to dry for about an hour before adding another.

Spray each layer evenly over the hot tub, and don’t worry about getting paint underneath your dangling faucets or any other hardware.

Step 6: Sand the Outside of Your Tub and Clean Up

After the paint has dried for about an hour, sand it and clean up all excess paint.

You want to eliminate any imperfections that might show and smooth out any jagged areas from the spray foam.

If any spots have leaked, get some white vinegar and apply it directly onto them to help restore your hot tub’s water tightness.

Can You Paint A Composite Hot Tub?

Yes. You can paint a composite hot tub with quality paint.

Composite hot tubs comprise an acrylic or polyester material and typically have a linen finish, which you can paint with any paint.o

Before painting your tub, make sure you prep the surface thoroughly. This process, known as prepping and priming, ensures that your paint will last.

First, remove all loose material from the tub with a scraper or wire brush.

Next, use a power washer to remove any remaining debris from pores, voids, and under the edges of the tub shell.

Afterward, you’ll want to sand the rough surface with an electric sander, sandpaper, or palm sander. Be careful not to sand off the surface of your tub.

Next, you need to wipe it down with a tack cloth. This action will help remove any dust, dirt, or other particles and residue from the surface before painting.

Finally, apply a high-quality primer and then paint with a quality acrylic or polyester paint.

Ensure you use high-quality marine-grade paint if you have positioned your hot tub outdoors since it’s more durable than regular house paints.

After you’ve finished painting, make sure you allow it to dry for 48 to 72 hours before use.

Can I Paint My Hot Tub Surroundings?

Yes. You can paint your hot tub surroundings, but it takes patience. Before starting, you must first remove all previous paint or stains from the tub surround.

If you’re removing paint, you’ll need to use a chemical stripper or sand down the old surfaces, and then pressure washes both the surface and through your filter to remove any residue from these earlier applications of paint.

When using a chemical stripper, wear safety goggles to avoid inhaling anything toxic into your lungs.

Also, wear rubber gloves and a respirator to protect your hands, eyes, and lungs from the toxic chemical stripping away the old paint.

If you’re sanding the old paint off, you’ll need to thoroughly brush off any dust or splinters that result from the sanding process before continuing.

Scrub all surfaces of your tub surrounded with a recommended cleaning solution for hot tubs to ensure all the old paint residues come off.

Once you’ve stripped and sanded the old paint or stains off, you can use a solvent paint stripper or even a pressure washer to strip and remove any residual stain buildup.

Use a premixed epoxy primer and final coat of paint recommended for hot tub surrounds when you’re ready to begin.

Can I Paint My Hot Tub Cabinet?

Yes. You can paint your hot tub cabinet. However, you should know that painting your hot tub cabinet is not a DIY project.

The paint will need a professional painter to apply it, clean up and install hardware.

It is best to hire an experienced professional when attempting to paint your hot tub cabinet because of the many risks involved with painting a hard surface.

Take on this project if you are comfortable doing this task yourself and have some experience in DIY projects.

You need to consider a few things before painting your hot tub cabinet. You should understand that painted hot tub cabinets will not be as durable or last as long as those stained.

The paint itself is not 100% waterproof. Although paint gives a durable, hard surface on wood, it is still vulnerable to water damage.

This means you should only use your hot tub if you completely trust the paint job and do not plan to get the surface wet after you paint it.

When you’re ready to start the project, you will need to remove all the hardware from your hot tub. The wire and rods can be a pain to replace once the paint has dried on them.

You’ll also want to remove any silicone or cork added for the paint to adhere as expected.

If you are a professional DIYer and have some experience with painting, you should feel comfortable painting over your hot tub cabinet yourself.

However, you will want to research your paint job and learn more about the best paints. There are many paints made for their use on wood.

Some have a better finish than others and can better protect your hot tub cabinet.

Can I Change The Color Of My Jacuzzi Tub?

Yes. You can change the color of your Jacuzzi tub.

First things first, here are two tips to remember during this process:

1) Make sure the water in your tub is cool, and don’t use any harsh chemicals. These two things ensure the process goes smoothly and there are no harmful effects on your Jacuzzi’s finish or tub rings.

2) The paint is not for outdoor use, and you should avoid the effects of weather changes. So, if it’s raining outside, wait until it stops.

If you must paint during the summer months, take extra precautions to eliminate the effects of the sun and hot surfaces.

Let’s get started with colors

Paint colors that work well with your Jacuzzi tub are dark colors with a slight variation from one color to another. The darker, the better.

The result will be a very sleek, professional look and the best part is that it won’t change the shape of your tub.

You can change your tub color without first removing the cover plate and changing anything else. When you finish, you will have a brand new-looking Jacuzzi tub.

The process is straightforward to do. Follow these steps:

1) Clean the Surface Thoroughly

Make sure that there is no dust or other residue left on the surface of your Jacuzzi tub. Use mild soap and water in the shower, tub, or sink.

Once water covers the tub, grab a “Pete’s Natural Antique White” paint bottle.

2) Apply the Paint

This is where it gets complicated. You must apply the paint with a brush and make sure you get an even coat across all surfaces.

The best idea is to apply only one or two thin coats because thick layers are harder to dry.

Allow each layer to dry completely before adding another one.

The drying process will take about seven hours for each coat, and your tub will need 3-4 coats total, depending on the depth you want in color.

During the process, use a soft-bristle brush and cover any areas that you don’t want to paint. Make sure you wear latex gloves for this step.

3) Finish with Top Coat

After the last coat has dried, apply a top coat for shine and protection. This step is optional but highly recommended to protect the color from stains.

That’s it. You have now successfully changed your Jacuzzi tub color.

Can You Paint Plastic Hot Tub Panels?

No. You cannot paint plastic hot tub panels with any DIY painting product or water-based paint.

Painting over vinyl panels that have been in a hot tub can cause damage to the plastic itself, and the paint will not adhere as expected.

A better solution is to replace your vinyl panels if you want them customized with a new pattern, color, or textured surface.

The old ones are typically just screwed into the side of the tub, and you can remove them with little effort.

If you see any paint stains on your vinyl backings, you may be able to clean them up with a solvent and water-based paint stripper.

To prevent color bleed from the old vinyl backings, apply a non-toxic non-silicone water-based paint finish such as Thumbtack True White Finish Paste or Thumbtack Waterable Finish Fast-Drying Sealer.

How Do You Replace Siding On A Hot Tub?

You can replace the siding on a hot tub by cutting out a rectangle-shaped piece of heavy-duty foil and replacing the old siding.

If the area you need to cover is on the side or back of a hot tub, cut an inverted V-shaped hole in one corner of the foil and screw it into place, creating a new smooth surface.

The caulk will hold everything together while you move on, filling any gaps with spackle and cementing in place.

As a hot tub owner, you must maintain your hot tub’s valuable and usable life by regularly performing routine maintenance. You may have heard of the term “water chemistry.”

If you have, you are well on your way to understanding its role in maintaining the proper balance of water hardness, pH, and alkalinity.

This is necessary to keep contaminants at bay, maintain a balanced environment for beneficial bacteria and limit corrosion, to name a few.

If during the winter months, when chillers are not in use, it’s essential to drain and freeze water in the chlorine dispenser.

A damaged chemical dispenser can lead to algae growth; these algae will devour even more of your Spa’s precious water and ultimately make keeping it clean that much harder.

How Do You Paint A Fiberglass Tub?

You can paint a fiberglass tub by sanding it down with a sander or rough cloth and then use a polymer-based sealant to seal any small cracks.

After you’ve sealed the tub, clean it thoroughly and use a paint that the manufacturer has approved. You can also remove all the hardware from your tub before painting it.

To do this, remove any handles, spouts, or other fixtures so that they don’t get damaged during painting.

Paint your newly stripped tub by coating both sides with primer. After this, please wait for it to dry and coat your tub with a high-quality gloss or semi-gloss paint.

You can get the best results by using a roller and many thin coats of paint instead of two to three thick coats.

Afterward, wait for your paint to dry and then reattach any fixtures you may have removed before painting.

You can apply spray-on shellac instead of priming and painting your tub if you’re hurrying. This is the quickest way, and you will only spend a few dollars rather than hundreds.

However, if you want to finish your project properly, applying paint and then shellac will give you a job well done.


Hot tub painting can be tiring, primarily if you work alone, but the results are worth it. You may have different ideas about what you want your hot tub to look like or want to change the color.

You can make all these changes using these tips for painting your hot tub. So now that you have gotten all the information you need go forth and paint.

It will improve your mood and make it look more appealing.
