Bathroom Sink Drain Buying Guide

Important things to know when purchasing a new lavatory drain for a bathroom or bar sink:

Drains are measured at the threaded portion of the drain (this is the section that will go through the sink and countertop). A standard sink hole is 1-½” in diameter and will accommodate most lavatory drains. This information is listed with drain products.

Drains can be purchased with or without overflow openings. An overflow opening is a small hole drilled in the top of the threaded portion of the drain that allows overflow water from the sink to enter the drain pipe. If your sink features an overflow, it is very important to purchase a drain with an overflow opening so that your sink and drain function properly. If your sink does not feature an overflow it cannot be paired with a drain with an overflow opening.

Types of Lavatory Drains

Press and Seal Drain

Also called pop-up drains, press and seal drains are easy to operate and install. The pop-up mechanism is activated by simply pressing down on the drain cover.

Twist and Turn Drain

A twist and turn drain, sometimes called a lift and turn, features a small nob that is used to manually lift the drain cover. Like press and seal drains, these drains are very easy to install and do not feature any beneath the counter mechanisms. Twist and turn drains are closed by pressing the drain cover down and turning, or “twisting”, to hold in place.

Grid or Strainer Drain

Drains with strainers are often used in bar sinks and have no closing function. The grid on the drain cover allows water to flow through the drain at all times while blocking larger items.

Chain and Plug Drain

Chain and plug drains are operated manually by plugging and removing a stopper. These drains usually come with a small basket, or crumb cup, to keep unwanted items from falling into the drain when the stopper is removed.

Drain with Pop-up Rod

Drains with pop-up rods feature stoppers and lift rods that are activated by pulling up on the lift rod located at the back of the faucet. The lift rod is attached to the drain underneath the sink and will lift and close the drain cover.
