Shower Installation: What’s Involved


There are a variety of reasons why a homeowner will want to install new shower. You may be adding an additional shower to your home or if you have an older home this may be a first time shower install for you. The level of expertise required is quite low and most DIY homeowners can do this. However, there are those who are not proficient with tools and manual work and should therefore seek assistance.

Installing the Rough-in Draining

  • If there is no level stand already available, the new shower will require one. This is done by constructing a frame then covering it by addition of the plywood.
  • You can then cut an opening for the shower drain with a 4-inch hole-saw.
  • Once this is done, the rough-in drain plumbing can be installed beneath the base. It should consist of a P-trap and a drain line that leads to a point of discharge such as a sewer. The slope for the drain should be at least 1/4-inch per foot. The drain should be screwed onto the shower-base and the drain line should be secured with appropriate fittings and pipes to ensure efficacy of the new system.

Assemble the Stall

Different manufacturers have varying types of stalls and if you do not already have a set enclosure, you will need one. When you are planning to install a shower, look for those that are effective but user-friendly for the novice. The instruction manuals available should help you set up the walls and the door where applicable. The process is usually quite easy though the nuts and bolts will require the use of a wretch or screwdriver.

Set Up the Shower Faucet

  • The stall usually supports the faucet or the shower fixture in freestanding showers. Most will already have holes for this but if not, you can drill a one-inch hole and then connect it with the lockouts provided.
  • The faucet will have to be connected to the rough-in water supply pipes. Depending on the system, you may have to solder copper pipes with the appropriate fittings. However, most modern plumbing will only require you to glue the plastic pipes to the fittings and then these with a plastic pipe primer using cement. This should direct the water into the stall through the faucet fixture.

Attach the Showerhead

  • This step is very simple since all that is required is connecting the showerhead to the faucet and tightening it. Manufacturers will have different instructions on the installation of the product.
  • It is also possible to have the handheld hose extender and it is installed by connecting to a fixture with a diverter. It will require some Teflon tape to ensure it stays in place in the secondary neck of the diverter.
  • If you are satisfied that everything is correctly installed, you can test for leaks by trying out your new shower.

The procedure on how to install new shower is quite straightforward and making a serious mistake is highly unlikely. For more complicated renovations or a complete overhaul of the bathroom, seek skilled professional assistance from a qualified plumber.
