Congratulations on your decision to renovate your home. Not everyone is brave enough to take such a risk. Dealing with the right size of shower drains can be quite tricky. Especially if you are trying to convert it.

How to reduce 2-inch to 1.5-inch shower drain?

There are 6 steps to this task. First, you’ll need to prepare the work area. Then, cut the tiles around the drain. Then drain covers need to be taken off. When you see the pipes, you’ll need to mark the place to cut them. After that, apply thin-set mortar and set the tiles again. 

We’ve only mentioned the gist of the whole process. However, there’s more to it. Let’s get started on learning how to execute this procedure!

2 Inch to 1.5 Inch Shower Drain: Just With 6 Steps

First off, it’s a good idea to make a temporary shower during renovation. Since you can’t use this bathroom during this period, this would help

Getting a 1.5-inch shower drain has many benefits. It isn’t rocket science to do it. 

All you’ll need to do is follow a few steps. You may simply perform a terrific job at home with a little patience and time. To undergo the task, you’ll require a few items. Let’s take a look at what you’ll need. 


Cross-check these tools to make sure you have all:

  • Angle Grinder
  • Screwdrivers
  • Thinset Mortar
  • Wrench Pipe
  • A scale
  • Pencil

You’ll need to get screwdrivers that will fit the drain cover. It’s best to check which type would fit.

While we are on screwdrivers, you should buy the best quality ones. On that note, here are the top two products we’ve gathered for your convenience-

You now have a fairly good idea, so we can proceed to the steps.

Step 1: Preparing Work Area

Please make sure the floor and work area are clean before beginning the procedure. Another crucial consideration is that dirt or filth cannot enter the shower drain. 

The folded pre-assembled sealing membrane or a towel can be used to shield the drain. Will multiple people use the shower? If so, you need to consider the shower dimension for two people.

Step 2: Cutting the Tiles

You’ll need to cut the tiles surrounding the drain area. First, cover the shower drain with a sheet of tracing paper. With a pencil, trace around the drain’s outside border on the paper. You’ll need to cut out this section of the tile. To do so, you may use an angle grinder. 

Step 3: Taking Off Drain Covers

After you are done with tiles, move on to drain covers. Using a wrench pipe, adjust the hex portion of the locknut of the shower drain. This is located beneath the subfloor. 

Turn the lock nut counterclockwise to loosen it. Allow the nut to slide down over the drain pipe. Then, pull it down to remove it from the drain body.

Step 4: Cutting the Pipe

It’s time for the main thing. Trace the drain pipe’s course with a scale to determine how much you’ll need to cut. After you’ve figured it out, grab your pencil and unleash your inner artist! 

During marking, try to be as exact as possible. Even if you’re not a great artist. Otherwise, you risk cutting the pipe more than is necessary.

Find a suitable central position on the pipe. Then, you can make a straight cut and still have enough pipe to attach a coupler. You’ll need to use an angle grinder to cut the iron pipe. 

After you are done cutting, get rid of the leftover pipe. Measure to see if you have 1.5 inches. Once you are done with the job, make sure you screw the drain cover into place. 

Step 5: Applying Thinset Mortar

You’ll need to retile the bathroom floor. Before you do that, you’ll need to apply the thin-set mortar. This will make sure the floor is not uneven. 

The first thing you’ll need to do is mix the thin-set mortar. Pour a few inches of liquid into the bottom of a 5-gallon bucket before adding powder. 

After mixing properly, dump the mortar into the surface and spread it over the three-inch surface. Finally, please comb the mortar. Make sure to produce an even surface. 

Step 6: Retiling the Floor

Once you’ve applied thin-set mortar to a part of the wall, it’s time to attach the tiles in place. Ascertain that the tiles are in the same location as before. If required, refer to the number while placing the tiles.

While renovating, you should keep in mind the duration of retiling a bathroom. Make sure to be very careful to avoid any mishaps.

And that’s it. You have successfully converted your shower drain to 1.5 inches.


Question: How long will it take to renovate a bathroom all by myself?

Answer: This is mostly determined by your skill level. Also, how quickly you can work. You can do the job in a week if you work 5-6 hours every day.

Question: Why is it important to have a level shower drain?

Answer: To ensure that all water is drained, floors must be slanted towards the channel. If it’s not leveled, water may clog. 

Question: Why are tubs and shower drains different sizes?

Answer: Your house’s draining system has different pipe diameters. To meet it, tubs and drains have different connection sizes.
