What Size Bottle Trap for Bathroom Sink?

Choosing the right size bottle trap for your bathroom sink is essential to prevent leaks, ensure proper drainage, and maintain a hygienic environment.

P-Trap:

Resembles the letter "P" and is commonly used under sinks and lavatories. -

S-Trap:

Drain Pipe Diameter:

The diameter of the drainpipe, usually 1-1/2 inches for sink drains, determines the minimum size of the bottle trap. -

Sink Basin Size:

Larger sinks require larger bottle traps to accommodate the increased water volume. -

Height Requirements:

The bottle trap must be tall enough to create a water seal that prevents sewer gases from escaping into the bathroom. -

Tailpiece Length:

The tailpiece, which connects the bottle trap to the sink drain, varies in length depending on the distance between the drainpipe and the sink basin. -

Clearance Under the Sink:

Adequate clearance below the sink is necessary to accommodate the bottle trap's height and the drainpipes. ### Standard Bottle Trap Sizes The most common bottle trap sizes for bathroom sinks range from 1-1/2 inches to 2 inches in diameter. The following table provides guidelines for selecting the appropriate size: | Drain Pipe Diameter | Bottle Trap Diameter | |---|---| | 1-1/2 inches | 1-1/2 inches | | 1-1/2 inches | 2 inches (for larger sinks) | ### Troubleshooting If you encounter issues with your bathroom sink drainage, the bottle trap may be the culprit. Common problems include: -

Bad Odors:
