Bathroom tap handles come in many different styles. But they all basically attach to the faucet with a single screw. Once the screw is taken out, the tap handles can be removed. The water supply must be turned off to avoid the possibility of water spraying out of the faucet once the handles are off. The entire task of removing the tap handles in a bathroom is accomplished in only minutes.
Look under the sink and determine if there are individual shutoff valves. If so, turn each shutoff all the way clockwise to shut off the supply of water to the faucet.
Locate the screw that holds on the tap handles. Sometimes there are button caps that cover the screws. The button caps will sometimes have the letter C and H on them for the hot and cold taps. Use a flathead screwdriver to pry off the button caps to reveal the screws on the taps.
Use a Phillips-head screwdriver to unscrew the screw on each tap that holds on the handles. Pull off the handles by hand. If the handles are stuck, use a pair of slip-joint pliers to grasp them and pull them off the faucet stem.
Protect faucet handles by draping them with a cloth before grabbing them with the slip-joint pliers.
