Installing a two handle tub shower faucet is not something that is particularly difficult, and you can manage it in a few minutes if you really want to get the rest of the showering system to yourself. If you choose to, you can replace an old two-handle tub and shower faucet, or you can choose to go ahead and fit a brand new one. Installing or replacing a two-handle faucet is not very difficult, and if you need to get this job done quickly, or cheaply, then you can do no better than doing it yourself. With a few simple home improvement tools and a few hours to spare on the weekend, this project can be managed easily.
Step 1 - Turn off the Water
The first thing that you need to do is turn off the water supply to your bathroom. The best way to manage this is to turn it off at the mains, which is usually positioned somewhere behind the house, or in a garage. If you have a shut-off valve, then you can simply turn this in order to cut off the water supply, but if not, then you will need to turn off the water using a wrench. Once this has been done, run the water in your upper and lower bathrooms in order to drain water from the pipes. Don't try and install the two-handle tub and shower faucet until the taps run empty.
Step 2 - Remove the Old Taps
You will now need to remove all of the old pipes and taps which are connected to the tub and shower. Most often, the shower handle will be held together with a screw through the central panel. Pop off the outside cover using your screwdriver, and then remove the large screw. The handle should pull away, and you will be looking at an escutcheon plate, which keeps the handle away from the valve. Open up the plate by prising it away from the wall, and you should have access to the water valves and the pipes.
Step 3 - Attach the Handle
Remove the old union from the pipes, and position your new two-handle faucet in its place. Solder the pipes to the union, making sure that there are no gaps in the solder. You should then connect the water valve to the union. When this is done, add the pipe onto the shower head to the union. You should have a clear space which is dedicated to the shower cap, and this is the perfect place for it. Add the handles to the outside of the union, and connect any spouts which also need to be added. When you have finished, replace the escutcheon plate, and add a layer of caulking around the edge. Caulk along the edge of the pipes and the union, and then leave to dry.
