The main distinction among bath sinks is how and where they’re mounted. Here are the top options:
Countertop: This is the most common installation, with the sink sitting in or on a countertop, typically as part of a vanity unit with cabinetry. Countertop sinks generally offer good storage and elbow room, as there is usually a sizable surface around the basin and cabinetry. This category includes the following:
- Top-Mount or Self-Rimming Sinks: These sinks have rolled edges that allow the sink to be dropped down into a countertop opening. Top-mount sinks are the easiest to install.
- Undermount Sinks: They are mounted below the countertop, exposing the edge of the countertop surface around the sink. With no rim to contend with, undermounts are easy to clean.
- Vessel Sink or Above-Counter-Sinks: These are basins that sit atop the counter and offer the most striking style.
- Integral Sinks: The countertop and sink are a one-piece unit made of the same material and sized to fit standard vanity widths. These sinks are also easy to clean.
Pedestal: A pedestal sink consists of a basin atop a tall, slender base. It’s often considered a vintage look, but there are contemporary versions, too. Pedestal sinks work well in powder rooms and small baths where counter space or storage isn’t a priority.
Wall-mount: Often found in commercial and institutional settings, wall-mount sinks work in home baths, too. They hang from the wall at a comfortable height and are open below -- the drainpipe and water supply lines are exposed. Wall-mount sinks are affordable, work well in small baths, and create a clean, open look. However, with the plumbing visible underneath, it calls for an attractive pipe finish, such as polished chrome.
Console: A popular variation of the wall-mount sink is the console sink, which resembles a traditional console table found in an entry or hallway. A console sink is basically a wall-mount sink with legs -- usually two but sometimes four. Some console sinks offer generous counter space and open shelving below.
