drain funnel

Listings indicate bathroom and shower drains are commonly made from stainless steel, steel, and brass.

Pop-up drains fit sink hole diameters from about 1 7/16" to 2 5/16" and deck thicknesses from 1" to 2 3/4". Vessel drains fit drain holes around 1.5"–1.9" with sink thicknesses about 0.78"–1.97"; one vessel listing also specifies a 1.25" drain pipe diameter.

Some shower and floor drain listings specify a high flow capability of about 20–25 L/min.

Many drains include removable strainers, filter baskets, or anti-clogging basket strainers (hair catchers) to trap hair and debris and reduce blockages.

One listing recommends cleaning shower drains every two weeks to prevent hair and debris buildup. Features that ease maintenance include removable covers, hair catchers (filter baskets), and small lifting hooks for removing strainers.
