There are various styles of shower heads, both regular and pulsating, all of which normally connect to a 1/2 inch threaded shower pipe. Many years ago there were pipes with a built in ball end. Those pipes must be replaced with a threaded end. Sometimes they are difficult to remove. Most balls you see when removing the original head have been screwed on, even if they are very tight, to the shower pipe. If you see even one thread, the head is normal.

Step 1: Use masking tape on the chrome pipe to protect the finish from being scratched when using wrenches or pliers. Use either vise grips and a pair of pliers, or a pipe wrench and pliers to remove the old shower head.

Step 2: Replace the Teflon tape on the end of shower pipe to prevent leaking.

Step 3: Put on the new head according to the manufacturers instructions. Remove the masking tape and you are ready for a shower.
