Take accurate measurements of the area where the cabinets will be installed. Measure all dimensions - depth, width and height. Recheck your measurements. It is extremely important that these measurements are correct.

Draw a diagram of the area and include the dimensions of the area where the cabinets will be installed. Measure and write down the size and location of the existing cabinets, if any. (You may want this information to note what cabinets are being replaced, or you may want to buy the same pieces or get a larger cabinet for a certain spot.)

Visit several cabinet vendors. Include both upscale cabinet/kitchen showrooms and major home centers.

Look at the cabinets and select the styles that you like.

Understand how cabinetry is priced: Cabinet prices are based upon the quality of construction and the materials used. Special pieces (fancy corner cabinets or those with special features such as lazy Susans) are considerably more expensive than basic cabinets. Cabinets are priced by the unit (cabinet), although some showrooms will offer the costs of display kitchens on a per-square-foot basis as well.

Ask salespeople direct questions. Inquire as to the specific reasons why one line is more expensive than another. Make sure that you understand the differences in both cost and construction.

Review your dimensions with a designer at the showroom.

Develop a plan that works for your needs and budget. Most showrooms today have computers that allow the supplier to print out plans, materials lists and even 3D views. (Remember to consider your appliances when developing the design.)

Confirm that your plan includes all the features that you want, including trim packages and other extras that may be included with the showroom displays.

Execute a contract for the purchase of the cabinets. Specify an outside delivery date and note if the vendor will provide installation services.
