Place your measuring tape against the wall and pull it out to the edge of the counter to determine how much room lengthwise you have to work with. Generally, you do not want a sink to come to the edge of the counter, so be sure to account for that in your measurements.
Place the edge of the measuring tape against the far edge of the counter and draw it horizontally across the counter, until you reach the point where you want the sink to stop. Make a note of the measurement on a notepad or piece of paper. This is the maximum width your new sink can be.
Get underneath the counter and measure from the bottom of the counter down to the floor. This will allow you to determine how deep your sink can be.
Stay under the counter and hook your measuring tape around the nearest water pipes, and then draw it over to where your new sink will be. This measurement will be approximately how much new pipe you will need to lay in order to hook the new sink into the water line. It will be approximate because different sinks have different drain configurations.
Things You Will Need
- Measuring tape
- Having a sink picked out before you start measuring can give you a more accurate view of what it will look like when it is finished as you measure, and this will alleviate some of the guesswork associated with how much space you will need to make it actually look good.
- If you can't draw a straight line from the pipes due to cabinets or other items blocking your way, unwind the measuring tape outside the cabinets and place it on the floor approximately where the pipes start, and draw it out to approximately where the sink will be. This will give you a rough estimation of how much new pipe you will need.
