A lovely home is a wonderful place to live. With great fixtures and appliances, homes will be much more efficient and easier to operate in. That’s why in this post I’d love to show you how to install tub and shower faucet.

Installing the best shower and tub faucet is not as easy as it is to install a faucet on a kitchen sink or dining sink. This is because the main part that’s operates the shower/tub faucet which is the valve will always go the wall.

Meanwhile, the parts that will remain visible on the shower tub faucet such as the spout, handles, and showerhead are often considered trim. Because of these characteristics, it means that if you have to install a tub or shower faucet you better do so before the walling is done.

However, if you intend to replace an already existing one, you will be forced to cut through the main wall or possibly use the main access door that builders leave – if you have one. I hope you do.

Install a Shower Faucet New Construction

Now let’s take a look at how to install a shower faucet new construction. I give you the best guide to work with and one that you will find to be pretty helpful. But first, let me give you the tools and materials that you will need for this project.

  • 2-by-6-inch lumber Screws
  • Plumbing tape
  • Propane torch
  • Lead-free solder
  • 1/2-inch copper pipe
  • Two 1/2-inch brass drop ear elbows
  • Two 1/2-by-6-inch nipples
  • Strap wrench
  • Pipe wrench

Step I:

For starters, you will have to install a 2-by-6 blocking. This blocking should be set on the enclosure’s framing. It is intended to support the main valve, the showerhead, and also the spout stub-outs.

The valve blocking that you have put must be on a high enough level so as to make it much more convenient for both the children and the adults. I would suggest placing the blocking at about 40 inches. This will enable them to easily operate the handle.

In addition to that, your blocking should be offset from the front part of the wall. When doing this, make sure that you work with the amount specified on the faucet’s installation manual and instructions.

Step II

Once this has been done, make sure that you secure the faucet’s valve to the main blocking with the screws. Make sure that as you secure this, you have basically positioned it in the correct orientation.

To do this, follow the arrow that has been used to indicate the top section and to determine which side goes under.

Step III

Next, connect your main water supply pipe to the main water inlets. Follow the right procedure depending on your model.

Remember that some valves also have male threaded ports while the others have the female threaded ports. More complex options have slip connectors.

NOTE: When connecting the pipes with the threaded fittings make sure you wrap a plumbing tape around threads first. And if you are soldering the pipes into the main slip connections you should use lead-free solder and propane torch.

Step IV

Now install the 1/2-inch pipe which rises from the main valve into the main blocking that you installed for your shower head. Terminate the pipe using a brass drop-ear elbow that you have secured to the main blocking with the screws.

If done, you can then install a pipe that goes to the tub’s spout by following the same directives. And screw temporary 6-inch nipple on either elbow to prevent any debris from getting into the pipes when you will be doing the walling.

Step V

Now it’s time to cover the wall. However, leave a gap of 1/2 inch all-round the valve and handle. You should also leave a gap of the same size for the stub-out that the shower head and spout will come through.

Step VI

Once this is done, you can then slide the decorative plate most shower systems come with around the handle. Attach the handle independently by following the manufacturer’s instructions. Check if your faucet has temperature limiter and install it before you attach the handle.

Step VII

Unscrew temporary nipple from showerhead elbow and screw in your shower arm. Tighten the elbow using a strap wrench and then screw on the showerhead. Use your hands to tighten the two fixtures together.

Step VIII

Make sure you also remove the nipple from its spout elbow then find a nipple of ideal length and screw it in. Use the pipe wrench to tighten the fixtures together.

Additional Tips

How to install a shower faucet new construction won’t take you so much time or prove challenging if you have the right guide. More importantly, you should remember the following tips to make your work easy.

  • When making plumbing connections you can also use PEX pipes and fittings.
  • If you use PEX pipes and fittings make sure you use adapters on the valve.
  • It is recommended to install a water hammer arrestor on every supply pipe. This will prevent loud sounds within the pipes as you use the water faucet.
  • Leave an access panel – to help you in accessing the plumbing section in the future

Conclusion

Now you know how to install tub and shower faucet. Nonetheless, it is very important that you cap all the nipples around the showerhead and the spout elbows. You should also make sure that you test the system if it works properly before you cover the wall.

In case you find a leak in the system, make sure you fix it before you do the walling. Leaks will cause very serious damage to your framing and might leave you with so much additional costs to go with.
