How to Measure an Opening for a Built-In Dishwasher
Measure cabinet opening width, height and depth, then check the dishwasher’s door swing, hookups and delivery requirements.
A nominal 24-inch dishwasher still has to fit the finished opening in your kitchen. Measure width at the top and bottom, and measure height from the finished floor to the underside of the counter at both sides. If new flooring stops in front of the opening, tell the installer. A change in floor height can complicate removal or replacement.
Use the installation drawing for the exact model
Compare the drawing’s required opening with your measurements. Check where the water supply, drain and electrical connection must be. The Bosch installation instructions show why enclosure and utility locations matter, but use the instructions for the model you are buying.
Check access with the door open
Make sure the door clears adjacent handles, the island and the floor. Confirm that you can pull the racks out without blocking the spot where you normally stand. For a panel-ready model, check the panel dimensions, weight and mounting instructions before ordering a custom front.
Confirm the job with the installer
Send the dimensions and a photo of the opening. Ask whether removal, new hookups, mounting parts and disposal are included. Verify the path from the exterior door to the kitchen. Once you know which machines fit, compare operating features using the ENERGY STAR dishwasher guide.
