The elbow pipe will be under the place where you will be installing the shower drain, and it is solvent-glued type. At first, you have to adjust that elbow pipe according to the surface by trimming it as it remains ¾ -1 inch under the floor. 

Step-2: Drain Tail Adjustment 

You will see a small drain attached to the shower body, which you will have to connect with the elbow pipe. First, you have to measure out how much gap is between the elbow pipe and the drain tail. The tail needs to get into the elbow-pipe fitting snugly. 

Step-3: Drain Tail installation with Glue 

After that, brush the shower drain box’s glue to the elbow pipe’s inner part and the outer part of the drain tail. Then you will have to twirl the drain-tail that it gets into the elbow pipe. The glue will take a bit of time to join the drain tail and the elbow pipe.

When the glue will stick, and the elbow pipe and the drain-tail will be joined together, you will have to install the shower drain body. Put the drain-body over the drain-tail, and then twirl it again to get joined with the drain-tail. You have to use cement to make sure that the tail and body are joined together.

Method 03: How to Install a Tile Shower Drain

You will get to know about how to install a shower drain for tile from below.

Materials That You Need:

⦁ Screwdriver.
⦁ Hacksaw.
⦁ Cement or glue.

Step-1: Preparation of the elbow-pipe 

The first thing that you need to find a lower place for installing the shower drain. This sloppy area of your bathroom needs installing a waterproof membrane liner, which will be between the flanges. It would be best if you cut the elbow pipe to a level of ¼ inch below the surface. 

Step-2: Bottom and Middle Flange installation 

Both the bottom and middle flanges need to be installed correctly for the Tile Shower Drain’s whole installation process. These flanges should be in the way of sandwiches as the liner will be in the middle portion. The leakage check in the liner part should be done after the bottom and middle flange installation. 

Step-3: Strainer installation  

You will have to install the metal strainer after the bottom and middle flange installation. The metal strainer needs to be put on the drain tail that will be connected with the sewerage line. 

All the screws, nuts, and bolts should be tightened to keep the joints fit and snug for a long time. Without tiling, this metal strainer will be a bit higher than the surface.  

Step-4: Tiling part 

Then you will have to start the tiling process after the strainer installation. After the floor construction with tiles, it will become higher, and the strain part will be lower than the new tiled surface. 

So, water will go down the line with the help of gravity. Thus, installing a shower with no access to the bottom will be done through the Tile Shower Drain.
