Most people think that they need a special size pipe for their shower drain. However, this is not the case. The size of the pipe needed for a shower drain is actually quite standard. Most homes have a 1/2-inch or 3/4-inch pipe running to the shower drain. This is typically enough to handle the water flow from a shower.

If you are having a problem with your shower draining properly, it is likely due to blockage in the drain, not the size of the pipe. If you have a clog in your shower drain, you can try using a plunger or a plumbers’ snake to clear it. If these methods do not work, you may need to call a plumber to help clear the blockage.

What Size Drain Pipe Do You Need for a Shower?

The size of the drain pipe you need for a shower depends on the shower tray or base you are using. If you are using a standard shower base, then you will need a 2-inch drain pipe. If you are using a large shower base, then you will need a 3-inch drain pipe.

Factors to Consider When Choosing a Shower Drain Pipe

When you are choosing a pipe for your shower drain, there are a few factors that you will need to take into account in order to make sure that you choose the right size. The first factor is the amount of water that your shower will be using. You will need to know how many gallons per minute (GPM) your shower will be using in order to choose the right size pipe.

The next factor is the distance that the water will be traveling from the shower head to the drain. The further the distance, the bigger the pipe you will need in order to prevent any clogs or slow drains. The last factor to consider is what kind of soil you have. If you have sandy soil, you will need a bigger pipe than if you have clay soil.

Now that you know what factors to consider when choosing a pipe for your shower drain, you can narrow down your choices and find the perfect pipe for your needs!

Tips for Installing a Shower Drain Pipe

Installing a shower drain pipe is not a difficult task, but there are some words of caution that need to be heeded in order to avoid any future problems. Here are some tips for installing a shower drain pipe:

-Make sure that the drain pipe you select is the correct size for your shower. Generally, a 1/2 inch pipe will suffice, but if you have a large shower or one with multiple showers heads, you may need a larger pipe.
-It is also important to make sure that the drain pipe you select is durable and will not corrode over time. PVC pipes are a good option as they are resistant to corrosion and easy to clean.
-When installing the drain pipe, be sure to use plumber’s putty or silicone caulk around the base of the drain to create a watertight seal.
-Once the drain pipe is installed, be sure to test it by running water through the shower and checking for any leaks.


Be sure to read the instructions that come with your shower drain kit carefully. Many kits will require you to use a hacksaw to cut the pipe to size. Once you have everything you need, follow these simple steps and you’ll have your shower drain installed in no time.
