A good rule of thumb for new appliance delivery and installation is, "measure twice and install once." Remember, in addition to measuring the appliance space for your washer-dryer combo, you need to measure all the doorways that your new appliance will travel through when coming inside. You will also want to verify that you have the right voltage outlet available for your machine.
When considering how much space you have for your washing dryer, expect to leave an extra 1" - 3" on the sides of the machine and 4" - 6" on the back for the washer accessories, like hoses and cords, and dryer accessories. Keep in mind, for homes without a devoted laundry room, you may need a ventless wash and dry machine.
