Chances are, your old shower head will simply unscrew from the curved arm that sticks out of the wall. Alternatively, if it's a really old shower head, it may be attached to an arm with a ball fitting on its end. If that's the case, you'll probably need to call in a plumber to remove the the old arm and shower head, and replace it with a new arm that has a threaded fitting on the end. Fortunately, you don't see the old ball-fitting types of arms very often, so very likely, that won't be an issue. Assuming that you have a threaded arm, all you probably need is an adjustable wrench (also commonly called a crescent wrench) that will open wide enough to accommodate the threaded fitting on the shower head. As you look at the fitting, you should notice that it has two flat sides. Simply adjust your wrench so that the flat sides fit into the jaws of the wrench, and gently turn the fitting counter-clockwise. Once it loosens, you should be able to twist it the rest of the way off by hand. To install the new shower head, wrap some teflon tape tightly around the threaded fitting on the arm. I like to go around the fitting a couple of times with the tape stretched tight. Now screw on the new shower head. Screw it on finger tight. That's probably enough. You don't want to over-tighten it. Turn on the water, and you should be in business. If the fitting leaks, try tightening a bit more by hand. If that doesn't stop the leak, try tightening the fitting very gently with the wrench, but don't force it. If it still leaks, remove the shower head and the teflon tape that you put on the threads earlier, so that the fitting is once again smooth. Now apply new teflon tape, but this time wrap it around 3 or 4 times, and try again.

we have these in our baths. it replaces the existing head and provides a handheld. either or both cna be used at once. if the link does not work goto lowes and it is item 65183 Peerless handhels massage shower head. teh handheld unit has a suction cup mount that you put anywhere and can move easily. turn the dial to provide water to the handheld, and if you want the regular head to work you turn it on during your shower and back to handheld when done. this way she does not have to stand to do it. we got it because 2x my wife has had to use a shower stool, once for a torn ACL and once after her Csection. BTW, it was actually cheaper to buy this than it was a handheld and a diverter seperately. Here is a link that might be useful: peerless shower massage handheld head

Not only great Pizza, but back in the day Dental Cavities seemingly were not a big deal. I was born and raised there and got my first cavity at age 17 - a few months after I joined the Navy to "see the world." (Turns out I spent 24 years in the Submarine Service... lousy view., good food...

I struggled with that decision as well. After LOTS of research and analysis, we decided on the fixed shower head and hand-held and are very happy with it. The shower head, while larger, still has plenty of pressure and it is adjustable (tilts left/right and up/down, so you can control spray direction). The hand-held is great for rinsing down the shower as well. I'm kind of a nut about maintenance and this makes it so easy. It's all personal preference. Here's mine: Hansgrohe #27112. Good luck!
