How to Replace a Faucet on a Spa Tub

Quck answer

Changing a faucet on a spa tub is a relatively simple process. Here are the steps to follow:

1. Turn off the water supply to the tub. This is usually done by shutting off the main water valve.

2. Remove the old faucet by unscrewing it from the tub. Use a wrench or pliers if necessary.

3. Clean the area where the old faucet was attached to ensure a proper seal for the new faucet.

4. Install the new faucet by screwing it onto the tub. Make sure it is tight and secure.

5. Turn on the water supply and check for any leaks. If there are any, tighten the faucet further or use plumber’s tape for a better seal.

6. Test the new faucet by turning it on and off. Enjoy your newly installed faucet on your spa tub!

Remember to follow the manufacturer’s instructions and use the appropriate tools for the job.


A spa tub releases pressurized water through jets located inside the tub. The temperature of the water can be adjusted by using two faucet handles, similar to those found on a bathtub. Replacing a faucet on a spa tub follows a similar process as replacing a bathtub faucet, with a few minor differences. You will need common household tools and a replacement faucet handle from a home and garden shop or a pool/spa supply store.

Step 1

First, trip the circuit breaker in the fuse box that supplies power to the spa tub. If the power switch on the tub is not already set to “Off,” turn it off.

Step 2

Next, open the side panel located at the bottom of the tub. In some cases, you may need to remove screws using a Phillips screwdriver. Turn the water valves inside the tub clockwise until you feel resistance.

Step 3

Using a flathead screwdriver, insert the tip beneath a corner of the cap at the top of the faucet. Lift up on the tip to loosen and remove the cap.

Step 4

Using a Phillips screwdriver, remove the screw from inside the top of the faucet handle. Set the screw aside to use with the replacement faucet handle.

Step 5

Grip the faucet handle just beneath the hole at the top using a pair of pliers. With a hammer in your other hand, strike the side of the pliers that is farthest from you. Repeat this process until the faucet begins to turn counterclockwise. Remove the pliers.

Step 6

Unscrew the handle and pull it off the rod it is seated on. Set the handle aside. If there is a plastic tube over the rod, unscrew it using your fingers. If the tube is difficult to remove, use pliers to twist it counterclockwise and loosen it first.

Step 7

Remove the tube from the rod and clean both the rod and the base with a dry cloth.

Step 8

Place the replacement faucet handle’s plastic tube over the rod. If the tube has threads, screw it onto the rod in a clockwise motion.

Step 9

Screw the replacement faucet handle onto the rod and tighten it using pliers. To prevent scratching, wrap a hand towel around the faucet handle before using the pliers.

Step 10

Insert the previously removed screw into the top of the replacement faucet handle and tighten it using a Phillips screwdriver. Place the cap that comes with the replacement faucet handle on top and press down to secure it.

Step 11

Finally, rotate the valves counterclockwise to restore the water flow to the tub. Replace the side panel and reattach any screws if necessary. Restore power to the spa tub at the fuse box.
