Clogged shower drains are one of those small household annoyances we all have to deal with -- but one plumber's simple hack is making waves for solving it without harsh chemicals or expensive tools. In a YouTube short video, a home repair expert demonstrates how to unclog a shower drain using nothing more than a toilet plunger.

Instead of pouring chemical drain cleaners down the pipe (which can damage plumbing and pollute waterways), creator Plumber John (@plumberjohn) shows how to use a few strong plunges to break up the clog and get water flowing freely again. The method uses air pressure and good-old elbow grease rather than harmful chemicals, offering a quick, clean, and eco-friendly fix for a common problem.

"If you ever have a backup in your shower or even your sink, you wouldn't think to do this, but try the plunger. I guarantee this will help," he said.

To do it, just make sure there's enough standing water in the shower to cover the plunger's rubber cup, creating a tight seal. Hold the plunger upright over the drain and push down firmly several times to force air through the pipes. The pressure dislodges hair, soap scum, and other debris that clog it up. Once the clog breaks free, rinse the drain thoroughly with hot water to flush out any remaining buildup.

This same trick can work for bathroom sinks or tubs, though it's not a bad idea to have a separate plunger dedicated to non-toilet use. This hack is an inexpensive fix that avoids pouring toxins into your plumbing system and saves you from buying single-use plastic drain cleaner bottles.

Aside from being cheap and effective, this hack keeps chemical drain openers -- many of which contain sodium hydroxide and bleach -- out of your home and local waterways. Those products can corrode pipes and harm aquatic life when washed into the environment. By using mechanical methods like plunging or natural solutions such as baking soda and vinegar, homeowners can protect their plumbing and the planet at the same time.

Reducing our reliance on store-bought cleaners also cuts down on plastic waste from disposable bottles. For more ways to clean safely and sustainably, check out these tips for using natural cleaning products and explore similar eco-friendly cleaning hacks.
