Taking accurate measurements is a critical step in ensuring you will be
happy on install day.

• Take your time and be accurate.
• Round each measurement down to the nearest 1/8 inch.
• Use a pencil; it's easier to make corrections.
• Measure twice, just to make sure, and write clearly.
• On graph paper (preferably), sketch the rough shape
  of your room, then measure and note the following:
• All the interior dimensions including the width, height and depth.
• Necessary clearances.
• Note the location of any fixtures, faucets and the # of holes they require, electrical outlets, or any other structural obstacles.
