Learn how to unclog a tub drain with a drain snake in this step-by-step tutorial. Prevent future clogs with TubShroom drain protectors and other DIY plumbing tips.
A slow-draining or completely clogged bathtub is one of the most frustrating household plumbing issues. Whether it's a buildup of hair, soap scum, or other debris, a blocked tub drain can disrupt your daily routine and even lead to standing water in your shower. While many homeowners reach for harsh chemical drain cleaners, these products can damage your pipes and are harmful to the environment. A safer, more effective solution is to use a drain snake, a simple tool that physically removes clogs without chemicals. In this step-by-step tutorial, we'll walk you through how to unclog a tub drain using a drain snake, and share tips on how to prevent future clogs with the right drain protectors.
Before you begin, it's important to understand the anatomy of your tub drain. Most bathtubs have a stopper mechanism that can be removed to access the drain pipe. Once you remove the stopper, you'll see the opening where hair and debris accumulate. A drain snake, also known as a plumbing auger, is a flexible cable that can be inserted into the drain to break up or retrieve clogs. For this tutorial, we recommend using a high-quality tool like the Drain Snake Auger, 36 Inch, Power Drill Attachment, Hair Clog Remover for Bathroom Sink and Bathtub, Stainless Steel, Matte Black, which is designed to handle tough clogs efficiently. With a few simple steps, you can restore your tub's drainage and avoid costly plumber visits.

What You'll Need to Unclog a Tub Drain
Before you start, gather the necessary tools and materials. You'll need a drain snake (preferably one with a power drill attachment for easier operation), a pair of pliers or a screwdriver to remove the drain stopper, a bucket or towel to catch any water, and gloves to keep your hands clean. If you're using a manual snake, ensure it's long enough to reach the clog—typically 25 to 36 inches. The Drain Snake Auger, 36 Inch, Power Drill Attachment, Hair Clog Remover for Bathroom Sink and Bathtub, Stainless Steel, Matte Black is an excellent choice because it combines durability with a powerful drill-compatible design, making the job faster and less strenuous.
You may also want to have a flashlight handy to inspect the drain opening, and a small mirror to check for hidden clogs. If you're dealing with a particularly stubborn blockage, a wet/dry vacuum can be used to suck out debris after snaking. However, for most tub drain clogs, a drain snake alone will suffice. Remember, safety first: always wear gloves and eye protection, especially if you're using a power drill attachment.
- Drain snake with power drill attachment (e.g., Drain Snake Auger, 36 Inch)
- Pliers or screwdriver to remove drain stopper
- Bucket or towel for water spills
- Gloves and eye protection
Step 1: Remove the Drain Stopper
The first step in unclogging your tub drain is to remove the drain stopper. Most tub stoppers are either a pop-up style (with a lever on the overflow plate) or a twist-and-pull style. For pop-up stoppers, locate the lever on the overflow plate and pull it up to raise the stopper, then gently lift it out. For twist-and-pull stoppers, simply twist the stopper counterclockwise and pull it upward. If the stopper is stuck, use pliers to gently loosen it, but be careful not to damage the metal or plastic.
Once the stopper is removed, you'll likely see a buildup of hair and gunk around the opening. Use a pair of tweezers or a small hook to remove any visible debris. This alone may solve the clog if it's near the surface. However, for deeper clogs, you'll need to proceed with the drain snake. Place the stopper aside and prepare your snake for insertion.
Step 2: Insert the Drain Snake into the Drain
Take your drain snake and straighten the cable. If you're using a model with a power drill attachment, attach the snake to your drill according to the manufacturer's instructions. Slowly insert the tip of the snake into the drain opening. You may encounter resistance as the snake navigates the P-trap or bends in the pipe. Gently push and twist the snake to work it past these obstacles. Do not force it, as you could damage the pipe or the snake.
Continue feeding the snake into the drain until you feel resistance from the clog. This is the point where the snake has reached the blockage. For tub drains, clogs are often located within the first few feet of the pipe. If you're using a 36-inch snake like the Drain Snake Auger, 36 Inch, Power Drill Attachment, Hair Clog Remover for Bathroom Sink and Bathtub, Stainless Steel, Matte Black, you should have plenty of length to reach most common clogs. Once you feel the resistance, stop feeding and prepare to break up the clog.
- Insert the snake slowly and gently to avoid pipe damage.
- Stop feeding when you feel resistance from the clog.
Step 3: Break Up or Retrieve the Clog
Now it's time to tackle the clog. If you're using a manual snake, rotate the handle clockwise while pushing forward to break up the debris. For a power drill attachment, engage the drill at a low speed to spin the snake. The rotating motion will help the snake's tip bore into the clog, breaking it apart or snagging it. After a few seconds, slowly retract the snake while keeping it spinning. You may see hair, soap scum, or other debris clinging to the snake as you pull it out.
Repeat this process two or three times to ensure the clog is fully cleared. After each pass, run hot water down the drain to test if it's flowing freely. If the water still drains slowly, you may need to snake again or check for additional blockages deeper in the pipe. Once the water drains quickly, you've successfully unclogged your tub drain. Clean the snake with a disinfectant and store it for future use.
- Use low speed on a power drill to avoid damaging the snake or pipe.
- Run hot water after snaking to flush out remaining debris.
How to Prevent Future Tub Drain Clogs
After successfully unclogging your tub drain, the best way to avoid repeating this process is to use a high-quality drain protector. Hair is the number one cause of tub drain clogs, and a simple hair catcher can stop it before it enters the pipe. The TubShroom Ultra is a popular choice for bathtubs, as it fits directly into the drain and catches hair, soap scum, and other debris without restricting water flow. Its silicone design is easy to clean and reusable, making it a cost-effective solution.

Another excellent option is the ShowerShroom Ultra Matte Black Hair Catcher, Stainless Steel Drain Protector, Fits All Shower Drains, which is perfect for shower drains and offers a sleek, durable design. Both products are designed to prevent clogs before they start, saving you time and money on plumbing repairs. Simply install the protector in your drain and clean it weekly to maintain optimal drainage. By combining regular maintenance with a drain snake for occasional deep clogs, you can keep your tub drain flowing freely for years.
