A pedestal sink is one with a column base supporting a sink bowl, with no cabinet or vanity top. The sink fits inside of a small bathroom where space is limited. If you are installing a pedestal sink, there are several measurements to consider. Each measurement applies to a different part of the sink and may vary based on style or manufacturer.

Pedestal Sink Height

The height of most pedestal sinks is between 33 and 34 inches. This standard size suits most adults and allows for easy operation of the handles and convenient access to the sink bowl. At this height, the pedestal sink fits easily into any bathroom.

It is lower than hanging vanity cabinets, so it does not interfere with these appliances. Standard bathroom cabinets are 34 inches high. This height, however, may interfere with window sills.

Pedestal Sink Exterior

The width of the exterior of the pedestal sink bowl varies based on your model and manufacturer. However, most pedestal sink bowls measure 22 to 24 inches wide at the exterior. This is the total distance across the sink, from side to side. This measurement is important when figuring out which type of pedestal sink to install in your bathroom.

When installing the sink, you will need to measure space that is a bit wider than the exterior width of the sink. The sink is much wider at the top than the bottom pedestal, which makes it ideal for small spaces.

Distance From Wall

The width of the pedestal sink is also important when installing this appliance. The width applies to the distance from the front to the back of the sink at its widest point. If you're installing the sink against the wall, this is the distance it will protrude from the wall. Measure out this distance from your wall at the height of the pedestal sink to determine if you have room to install it.

Faucet Mount Measurements

The other measurement encountered when choosing a pedestal sink is the faucet mounting measurement. This applies only to the type of faucet you plan to install in the pedestal sink. Most pedestal sinks have pre-drilled holes to install a faucet. The holes must line up to match the mounting shafts on your faucet.

A typical pedestal sink includes pre-drilled center set faucet holes, each spaced 4 inches apart on center, or 8-inch spaced holes for a wide-spread faucet. Match the pedestal sink holes to your particular type of faucet for a proper installation.

Prepping to Install the Sink

Once you have prepared the plumbing for your new sink and measured the sink for its height, sink width at the top and protrusion from the wall, it will take about three hours to mount the sink. Once you've followed the faucet directions to connect the faucet and drain, installed the valves, drain stub and sink mounting bolts, you'll need to set the sink on the pedestal properly.

You may need to shim the pedestal, because the pedestals don't always mount perfectly. Use foam pads under the sink bowl to level it. Then mark the wall and floor for the mounting screws. You may need to use silicone caulk to fill in the floor gaps and the gaps between the pedestal and the sink bowl.
