Step-by-Step Method
Unscrew or pop out the drain cover. Most pry up with a flathead screwdriver or unscrew counterclockwise.
Using needle-nose pliers or a plastic drain snake tool (available at any hardware store for under $3), reach into the drain and pull out accumulated hair. This is the gross step but also the most effective.
Pour 1/2 cup baking soda down the drain, followed by 1/2 cup white vinegar. Cover the drain and let fizz for 15 minutes. Follow with boiling water.
Run the shower to test drainage. Install a drain cover with a hair catcher to prevent future clogs.
- Do not use chemical drain cleaners (corrode pipes and are hazardous)
- Do not pour boiling water down PVC pipes (softens joints)
- Pull hair from the drain cover after every shower. Takes 2 seconds, prevents months of clog buildup.
- Monthly maintenance: baking soda + vinegar + hot water flush prevents buildup.
Frequently Asked Questions
Hair is the primary cause. An average person sheds 50-100 hairs per day, and many of those come out during showering. Without a hair catcher, they accumulate in the P-trap and drain. A $3 silicone drain cover solves this permanently.
Sources & Methodology
Hair clogs are the most common residential drain blockage. Mechanical removal is more effective and safer than chemical drain cleaners.
