Blocked bathtubs can be caused by a variety of factors. Some of the most common reasons for bathtub blockages include:

• Hair: As hair falls out during baths or showers, it can accumulate in the drain and create a blockage over time.
• Soap Scum: Soap scum can also build up in your drain over time, creating a slimy layer that traps other debris and prevents water from flowing through.
• Mineral deposits: Hard water can cause mineral deposits to accumulate in your pipes, making it harder for water to move through.

Some signs that you may have a bathtub blockage include:

• Slow draining water: If your bathwater is draining more slowly than usual, this is a sign that there may be a blockage.
• Strange noises: If you hear gurgling noises when the water is draining from your bathtub, this can also indicate a blockage.
• Water backup: If water is backing up in your bathtub or overflowing onto the floor, this is a clear sign of a serious blockage.

If you're experiencing any of these issues, it's important to take action as soon as possible. A blocked bathtub can quickly become a major problem if left unchecked.
