A wall mounted sink can create the illusion of a larger room. It will also give you an area for storage, such as a wastebasket, that may not ordinarily fit with a full vanity or cabinet.

Wall-mounted sinks are typically found in offices and retail locations with large bathrooms but can also fit in nicely in a home bathroom. Depending on the plumbing set up in your home, support legs may be needed. Here's what you should know.

Step 1 - Determine if Support is Necessary

Sometimes when you add a wall-mounted sink you will find the plumbing doesn't always coincide with the design of the studs behind the wall. Since a wall mount sink is heavy, it needs to have strong support from the wall to prevent it from crashing through the wall onto the floor.

Even if you don't have the right setup, you can still install this type of sink. You will just need to add support legs to make up for what the wall can't handle.

Step 2 - Choose the Support Legs

If you have a simple sink, you are going to be able to choose pretty much any style of support legs you want. Having at least a small counter around the sink also helps with this, since the legs can be attached to the counter. If you are wanting to minimize the look of the legs, you can choose small legs that match the sink.

If you have a more vintage or classical look, you can choose iron legs that are decorative. When you add legs, the sink becomes a console sink, and table sinks are still very popular.

Step 3 - Consider Weight and Size

Since the support legs will be handling the bulk of the weight, this needs to be carefully planned before execution. Planning on adding support legs that are too weak for the sink will do nothing but get in the way. You will need an accurate weight for the sink when you decide on the best material for the support legs.

The measurements from the base of the sink to the ground also need to be considered. Legs that are too short, even by a few centimeters, will cause more strain on the sink and wall brackets.

Step 4 - Attach the Legs

Depending on the types of support legs, and the type of sink you have, you will have a few options to attach them. A sink with a counter will be the easiest to work with. The legs can be braced in the bottom of the counter. If you are wanting to add a brace to a free-standing sink, this can be done with a single support leg directly under the base of the sink.

This method will require you to either drill into the sink itself, or countersink a bolt into the support leg. If you must drill through the sink, you will need to cover this with a special porcelain sealer to prevent leaks later on.
