Measurement tips:

In order to get proper measurements for your vanity top, you wait to measure until your cabinets are permanently installed so there is no variation in size. Be cautious of sizes taken from cabinet drawings. These may not always included your exact vanity top size, especially for wall to wall tops or if revisions to the drawings are made.

How to take square measurements:

It is best to take a measurement from the left wall to the right wall starting first with the back of the cabinet. Next, measure the same way with the front of the cabinet. If it is more than ¼” out of square you may want to split the difference. For mostly square spaces, you may want to deduct slightly for ease of installation. If you want a tight installation, you can modify the vanity size with a belt sander.

For wall to open:

Start measuring from one corner of wall to end of cabinet adding 1″ overhang on any open sides.

For open to open:

When you measure, make sure to measure length of cabinet adding 1” over hang for each open end.

Measure depth of the cabinet:

Now measure from your back wall to front of cabinet and add 1” over hang to cabinet measurement.

Bowl Center:

Always measure from a fixed point (wall) if possible for accurate dimension. Measure from the wall to the center of the door for EACH bowl. If measuring from an open end, measure from the end of the cabinet and add for overhang. Front edge to back measurement is a set measurement depending on bowl style.

Template angle/Angle tops:

How to measure for a new bathroom vanity on walls that are not square

Want to do something special? No problem, but you will need to make a template. You will want to build a template for angles, curves, extremely out of square walls, etc. Make your template with stiff cardboard so that it will maintain its shape. Cardboard should be wider and longer than cabinet. Place cardboard on top of cabinet, cutting where needed. Hot glue the pieces together to form an exact template of the vanity top.

On bottom side of template, trace around entire cabinet. Once removed from cabinet, add 1” overhang to cabinet outline and draw out the outer edges of your vanity top with the overhang included. This should be the exact replica of your vanity top. We will manufacturer to your template and will not add any dimensions to what you have provided so make sure your template is exactly as you want it.

On top side of template, show your bowl centers as described above. Using a box knife, cut out template using the line on the bottom side that includes any overhang. Make note on topside of template any walls, open ends, bowl centers, special notes, etc. Remember, we will not alter your template so it must be supplied to us exactly as you want your top to be.  All notes should be made on topside of template.

Faucet Drill:

If using a new faucet, the box will tell you what faucet drill is required. Standard is either a single hole for single lever faucets or 4” for a faucet that has a spout and two handles as one piece.

Order a wide spread faucet drilling when your faucet has 2 separate handles and spout. Generally, anything from 8” to 16” are classified as “wide drillings”. These measurements are from center of left handle to center of right handle, center to center measurements.

The diameter of the hole is a standard 1 3/8”, which covers 99.99% of all faucets and is a standard set back from edge of bowl.
