A Jacuzzi or jetted tub can absolutely be refinished. The surface is typically acrylic or fiberglass — both of which take refinishing coatings well. The challenge is the jets, jet trim rings, and the complex shape of the tub body. None of that is a dealbreaker, it just requires more careful prep and masking. Before you dive in, it’s worth understanding whether refinishing a bathtub really works for your specific situation.
Here’s how to handle it.
Identify the Tub Material First
Most jetted tubs are:
- Acrylic — lightweight, warm to the touch, can have flex. Most common in newer construction.
- Fiberglass — slightly cooler, can be thinner, sometimes shows flexion cracks
- Cast iron — rare in jetted tubs, very heavy. Usually older installations.
The refinishing process is nearly identical for acrylic and fiberglass. If you have a cast iron jetted tub, the process is the same but the material is more forgiving.
Check your paperwork or search the model number if you’re not sure. Jacuzzi, American Standard, Kohler, and most brands list the material on the product page.
What’s Different About Jetted Tubs
1. The Jets Themselves
The jet nozzles, jet covers, and trim rings all need to come out before you refinish. Coating around them (or worse, over them) causes problems:
- Jets that can’t be removed properly after coating
- Coating that cracks at the jet ring edges
- Poor adhesion around the jet openings
Most jet nozzles unscrew or pop out with a quarter-turn counterclockwise. Trim rings usually pull off with a firm tug or have a small notch you can pry. Check the brand documentation if you’re unsure — most are designed to be removable for cleaning.
Remove all of them. Put them in a bag labeled with their location.
2. The Water Intake and Air Controls
The water intake (suction fitting) and any air controls also need to be taped off or removed. You do not want coating getting into the plumbing.
3. The Irregular Shape
Most jetted tubs have curves, jets at various heights, and contoured interiors. A flat foam roller won’t reach everything. Have a brush handy for the corners, jet openings, and curved surfaces.
The Full Process
Step 1: Deep Clean
Jetted tubs accumulate biofilm inside the jet plumbing. Before refinishing the surface, run a cleaning cycle:
- Fill the tub to above the jets with hot water
- Add 2 tablespoons of a low-suds cleaner or white vinegar
- Run the jets for 15 minutes
- Drain and rinse
Now clean the tub surface itself — the interior walls and floor — with a non-abrasive cleaner. Remove all soap scum, oils, and mineral deposits. Rinse thoroughly.
Step 2: Remove Jets and Hardware
Take out all jet nozzles, trim rings, water intake covers, and air controls. Keep them organized — you’ll be putting them back.
Plug the jet openings with rolled-up paper towels or painter’s tape folded into the holes. These need to stay completely free of coating.
Step 3: Sand or Etch the Surface
For acrylic: use 400-grit wet/dry sandpaper. Acrylic sands easily — you’re just scuffing the surface, not removing material. Wipe with a tack cloth.
For fiberglass: sand and/or use the etching solution from your kit. Fiberglass needs more prep than acrylic.
Cover every inch of the tub interior. The jets create natural visual sections — don’t skip the areas around them.
Step 4: Mask Everything Thoroughly
This is more masking than a standard tub:
- All jet openings (already plugged from Step 2)
- The drain and overflow
- Faucet and controls
- The rim/deck where it meets the tile or surround
- The underside of any lip that you’re not coating
Use quality painter’s tape and make sure every edge is pressed down firmly.
Step 5: Apply the Coating
Use the same kit you’d use for a standard tub — Rust-Oleum Tub & Tile is reliable for acrylic and fiberglass surfaces.
Apply with a brush first around all the jet openings, corners, and curved surfaces. Then use a foam roller on the flat areas. Two thin coats. Let the first coat reach the manufacturer’s re-coat time before applying the second.
Work methodically — jetted tubs have a lot of surface area. Start from the far end and work toward where you’re standing so you’re not reaching over wet coating.
Step 6: Cure
Same as any refinishing job — don’t use the tub for at least 48–72 hours. Full cure is 5–7 days. During the cure period, the jet openings should stay masked. Once the finish has fully cured, caring for a refinished bathtub properly will significantly extend how long it lasts.
Step 7: Reinstall Jets
Once fully cured, remove the tape from the jet openings and reinstall the nozzles and trim rings. Most snap or screw back in the same way they came out. Check that all nozzles turn freely.
Common Issues with Jetted Tub Refinishing
Coating around jet openings peels — Almost always caused by insufficient tape coverage at the jet edge, or coating that crept under the tape. Take extra care masking each opening and press the tape down firmly all the way around.
Jets hard to reinstall after coating — If coating got onto the threads or edge of the jet opening, you can carefully trim it with a razor blade once fully cured.
Uneven finish in corners — Jetted tubs have more tight curves than flat tubs. Use a brush in the corners rather than forcing a roller into spaces it doesn’t fit.
Is It Worth It vs. Hiring a Pro?
For a jetted tub especially, hiring a professional refinisher has more advantages than with a standard tub. The jet removal, complex shape, and larger surface area make the job more time-consuming, and mistakes are harder to fix on a premium fixture.
That said, a careful DIYer can absolutely do this right. If you’ve already done a standard tub and feel confident in the process, a jetted tub is the same principles — just more prep work.
