Standard Size Bathroom Sink Drain

The standard size bathroom sink drain is 1 1/2 inches in diameter. This is the size of the opening in the sink where the drain stopper fits. The drain stopper is typically made of rubber or metal and has a flange that fits into the drain opening. The flange helps to keep the drain stopper in place and prevents water from leaking out around it.

There are some bathroom sinks that have a 1 1/4 inch drain opening. These sinks are typically found in older homes. If you have a sink with a 1 1/4 inch drain opening, you will need to purchase a drain stopper that is specifically designed for that size opening.

In addition to the diameter of the drain opening, there are other factors to consider when choosing a drain stopper. The material of the drain stopper is important because it will determine how durable it is. Rubber drain stoppers are less durable than metal drain stoppers, but they are also less expensive. Metal drain stoppers are more durable, but they can be more expensive.

The style of the drain stopper is also important. There are many different styles of drain stoppers available, so you can choose one that matches the style of your bathroom. Some drain stoppers have a simple design, while others have a more decorative design.

Types of Bathroom Sink Drains

There are three main types of bathroom sink drains:

Pop-up drains are the most common type of drain. They have a stopper that pops up and down to open and close the drain.
Lift-and-turn drains have a stopper that is lifted and turned to open and close the drain.
Toe-touch drains have a stopper that is opened and closed by pressing on it with your toe.

Each type of drain has its own advantages and disadvantages. Pop-up drains are the easiest to use, but they can be more difficult to clean. Lift-and-turn drains are more durable than pop-up drains, but they can be more difficult to open and close. Toe-touch drains are the most convenient to use, but they can be more expensive than other types of drains.

Your personal preferences. Some people prefer pop-up drains, while others prefer lift-and-turn drains or toe-touch drains.

Once you have considered all of the factors, you can choose the right bathroom sink drain for your needs.
