Bathroom sink drain? Yes, the sink drain. Choosing the correct type and style of drain can totally change your interaction experience and the appearance of your bathroom. Many small and vessel type bathroom sinks do not come with a drain, leaving you with the problem of finding the appropriate size and finish to fit the sink.

Types of drains


Grid Type Sink Drain

There are a few different types of drain available with the most popular drain for small and vessel sinks being the pop-up touch type. As the name suggests, the drain center can be pressed down to seal the sink and when pressed again it pops up to drain the water. Another variety of push top pop-up drain is the type that is operated by a plunger or lever located at the rear of the faucet. However, on most small sinks, the standard type is the push top.

Another popular drain is the grid type, this type of drain cannot be sealed and the water is constantly draining. These drains are great if you don’t have an overflow and are worried about someone leaving the water on and flooding the room. They are also good at preventing obstructions such as hair from entering and clogging the sink waste output. If you just need to quickly wash your hands or face, the grid drain is an ideal solution.

Bathroom sink Drain Sizes

Drain holes are fairly standard, with 1.25 (1-1/4) inches being the most common. However, there are other sizes that are used, such as; 1.5 (1-1/2) inches and 1.625 (1-5/8) inches.

The easiest and quickest way to determine the size of the drain required is to look at the manufacturers specifications on the Amazon page. This should give you the exact hole size or the size of drain required. Also on the product page are the “Frequently Bought Together” and “Customers Who Bought This Item Also Bought” sections allow you to view the drains that customers purchased with the sink.

Drain manufacturers often give the maximum hole size the product will work with, so if you have the sink hole size check it against the drain makers minimum and maximum dimensions.

Drain with or without overflow

Important: If you purchase a sink without an overflow, you will need to purchase a pop-up drain without overflow. If you purchase a sink with an overflow, you will need to purchase a pop-up drain with an overflow.

Confused? Here is a brief explanation and image to help you understand the difference between drains with and without overflow.

In a sink with an overflow, water passes from the overflow hole near the top of the sink, down an enclosed passage within the sink to the overflow hole in the drain and gets expelled through the trap.
