I have a Jacuzzi Rainbow Faucet with the square handles & need to replace the faucet cover and handles but the chrome is no longer available. Is there another option without removing the everything?

Sounds like the setscrew that holds it on has either worked lose and is missing or is striped and no longer tightens properly. Replace set screw if missing and or replace set screw if the set screw is striped. If the threads are stripped in the faucet body the faucet itself will need to be replaced. This usually does not fall under Moen's warranty guidlines.

Throw a cloth over the cover to prevent scratching the finish and grab it with a large pair of channel locks and unscrew it.

With the detailed part number you have, I would just walk into stores like Home Depot or any plumbing store and they will give you the exact parts you need. They are not expensive and a lot of them are standard parts and come in kits.
Good luck.

There is a allen set screw on the handle it may have a cap over it locate it and unloosen screw and remove handle then un screw bonnet nut then replacement kits available at most hardware,home improvement,or plumbing stores take note of how the parts are removed so to reinstall the way they came out.

If a faucet is leaking the necessary repair will be either:
1. For a ceramic or washerless faucet, replace the cartridge.
2. For a typical old fashioned faucet, open the faucet, replace the washer (and packing if it has any) and verify that the faucet seat has not eroded.
The newer washerless faucets cannot be repaired except by replacing the cartridge. Cartridges for most common faucets are available at most home improvement stores or plumbing supply houses.
It sounds a lot more difficult than it really is, just shut off the water (usually a shut off valve under the sink). After the water is off, remove the handle and any chrome protective covering. Depending on the faucet type, it may be a little difficult to remove the cartridge since they are often covered with mineral build-up or corroded into place.
Once you remove the old cartridge the new one usually goes into place easily.
NOTE!!!
For single handle faucets, make sure you put it in the right way, some of them will put the hot to the wrong side if you put them together backward.

On the top of each handle you will need a very small flat head screwdriver or something similar to "pop" the top cap off. Under that cap there is a phillips head screw so you can remove the handle.

either mount on wall or need to drill holes through jacuzzi 99 % of tubs dont come with faucets

was lubrication used between the spout and the deck, if not a lubricant that won't degrade the rubber o-rings should solve your problem

firs you have to remove the handle

remove lastic cap on top or no cap look for a erasure size cap or ruber tab on the side

take a flashlight and determine if you need an allen head screw or phillps

remove the screw( be sure to cover your drains so nos small parts get in bottom

remove the handle

depending on the type of faucet you may have to unscrew a large nut holding the cartridge in place

whatever remove anything holding the cartridge down (some require a cartridege remover)

remove, take to store match up new and replace

by all means turn water of under sinnk good luck

TIP anytime you have to put a wrench on chrome protect chrome with a wash cloth

Yes, It can be fixed but it isn't a washer. There is a replacement stem for the faucet . They are readily available at most big box stores and possibly the local hardware store. Bring your faucet model number with you.
