How Do You Drain A Portable Bathtub

Draining a portable bathtub without a built-in draining option is much easier than you think. This guide will explore simple and effective methods to empty your portable bathtub. 

A Portable Bathtub

Whether you use a bucket, a portable electric water pump, a simple pipe or Create a Drain System, we’ll provide step-by-step instructions to help you effortlessly drain your bathtub. Say goodbye to standing water and hello to hassle-free bathtub drainage. So let’s get started.

4 Ways to Drain A Portable Bathtub

If your portable bathtub lacks a draining option, don’t worry! I’ve got you covered with some simple and hassle-free methods to empty it in no time quickly.

1. Use Bucket 

A bucket is one of the simplest ways to drain a portable bathtub. Depending on the volume of water in the tub, you’ll need a large or smaller bucket. Fill the bucket with water from the tub and pour it into a nearby sink or drain. Repeat this process until the tub is completely emptied. This method requires manual effort but is effective for smaller tubs.

2. Try a Portable Electric Water Pump for the Tub

If you prefer a more automated and convenient option, consider using a portable electric water pump designed explicitly for draining tubs. These pumps are lightweight and easy to use. 

You can place the pump at the bottom of the tub and connect it to a garden hose or an appropriate drainage pipe. Turn on the pump, and it will start sucking the water out of the tub and directing it to the desired drain. This method is fast and requires less effort compared to using buckets.

Note: Remember to exercise caution when using electrical devices or water drainage. Always follow the manufacturer’s instructions and take necessary safety precautions.

3. Simple Hose Pipe

Another method to drain a portable bathtub is by using a simple pipe. You’ll need a flexible hose or pipe long enough to reach from the bottom of the tub to a suitable drainage area. Place one end of the pipe at the lowest point of the tub and create a siphon effect by sucking on the other end until the water starts flowing out. 

Once the water starts flowing, place the free end of the pipe into a sink or a drain to let the water empty out. This method requires some initial manual effort to create the siphon. Draining more oversized portable bathtubs can take time, making the process, as mentioned above, less effective for such cases.

4. Create a Drain System

To create a drain system for a portable bathtub without an existing draining option, you can follow these steps:

Materials needed:

  1. Flexible hose or PVC pipe
  2. Rubber gaskets or washers
  3. Hose clamps or zip ties
  4. Hole saw
  5. Plumbing tape or sealant
  6. Sink or external drainage area
  7. Male/Female Threaded Outlet with Turn Ball Valve


  1. Choose a suitable location where you want the water to drain. It can be a nearby sink, a floor drain, or an external drainage area.
  2. Measure the distance from the bottom of the tub to the chosen drainage location. Cut the flexible hose or PVC pipe to this length using a saw or pipe cutter.
  3. You’ll need to create one if the tub doesn’t have an existing drainage hole. Use a Hole saw to carefully create a hole in the side or bottom of the tub, close to the bottom edge. Make sure the hole is the same as the diameter of the hose or pipe you’re using.
  4. Proceed by installing a Male/Female Threaded Outlet with a Turn Ball Valve into the hole of the bathtub. Additionally, incorporate an extra 2-inch long PVC pipe with a Turn Ball Valve.
  5. Next, connect a hose pipe to the PVC pipe and ensure a secure connection using hose clamps or zip ties. Position the other end of the pipe at your desired drainage location. Voila! Your setup is now complete.

Additionally, it’s a good practice to use plumbing tape or sealant on the threaded connections to prevent all leaks. 

What Type of Portable Bathtub is Not Acceptable to Build a Drain System?

In a fourth way, I have discussed the process and procedures of constructing a drain system in a portable bathtub. It is advisable to refrain from attempting this method on ceramic materials, as installing holes and kits without prior experience can be challenging.

Improper installation may result in significant damage to the ceramic tub. Exercise caution and consider seeking professional assistance when dealing with ceramic materials.
