Understanding the reason behind your blocked bathtub drain is the first step to resolve the issue. Generally speaking, the drainage of your bathtub may get blocked due to the following reasons:

• Hair: Simply put, human hair is the most common perpetrator that causes bathtub blockages. When you take a bath, tiny hair particles combine to form a strand, and over time, these strands accumulate and cause a blockage.

• Soap: While soap dissolves, it also leaves behind a residue that can stick to the inside of your bathtub drain pipe, which then builds up over time and causes a blockage.

• Mineral buildup: This is hard water, where minerals like calcium and magnesium can build up over time and clog the drain.

• Foreign objects: Sometimes, foreign objects can accidentally find their way into the bathtub drain, causing an obstruction in the drain pipe.
