6 Easy Steps to Bath Installation

Installing a new bathtub can seem a little overwhelming for the average do-it-yourselfer but with easy to understand instructions any homeowner can get the job done. Take a look at this easy to follow six-step process for installing a new bathtub.

1. Purchase the New Tub and Remove the Old

The first step in replacing a bathroom is to purchase a new tab. To keep the process as simple as possible it is best to purchase a tub that is the same size as the one you are replacing to avoid extra construction work. It is also important to choose a tube that drains on the same side as the old one to avoid having to reroute any plumbing.

Once the new bathtub has been selected it is time to remove the old one. This part of the process requires several steps, listed below.

  • Turn off the water and drain all supply lines by opening a faucet below the level of the bath
  • Piping needs to be exposed and the hot and cold faucets need to be removed all the way back to the supply connections
  • Disconnect the tub drain
  • Remove spout, drain and faucet
  • Disconnect all attached plumbing and pry the old bathtub out


2. Dry Fit the New Tub and Prepare for Installation


Start this step by placing the new tub in the appropriate spot and making the top on the wall studs, and proceed as follows.

  • Install the wall ledger paying special attention to make sure it’s level
  • Turn the tub on its side and assemble the shoe fittings
  • Dry fit the drain and water supply
  • Assemble the overflow pipe and fittings to make sure everything is aligned correctly


3. Complete the New Plumbing

Once you are confident that everything fits correctly you can begin to permanently install the plumbing. Start by applying a generous ring of plumber’s putty around the drain flange and sure to take off the flange thread. Also insert the washer on the shoe and screw the drain flange in the shoe tightly. The remaining steps to this stage are as follows.

  • Attach the drain and screw it tightly into place
  • Install the overflow cover


4. Secure the New Tub

It is critical the tub be properly secured. This process begins by spreading a generous layer of mortar on the sub floor where the tub will go and proceed to the next steps.

  • Secure with galvanised nails into the flange to secure it into the studs.
  • Connect the water and drain supply by pulling down the slip connection on the drain pipe and tightening
  • Seal the drain inside the tub with plumber’s putty and tighten
  • Screw the hot and cold water onto the supply fittings, sealing the male threaded with joint compound during tightening


5. Reattach the Taps and Showerhead

Now that the tub has been properly installed it is time to move forward with finishing details by installing the showerhead, spout and faucet handles so the tub functions as intended. This is a very simple process as they are usually installed by simply tightening the fixtures onto the fittings.

6. Repair the Cosmetic Details

At this stage the tub is properly installed and should be checked for leaks. If no leaks occur you can feel confident the plumbing is installed correctly and move forward in repairing any paint, tile or drywall that has been damaged through the process in order to install the tub and access the plumbing.

If you have any trouble following these steps, or you’re not confident in your plumbing abilities then calling in the professionals is a good idea. They will be able to install your new bath with ease, allowing you to relax and look forward to getting in for a good soak!
