Do laundry room cabinets need to match kitchen cabinets?

No. Not necessarily. If the kitchen and laundry are separate and not in sight of one another, you have a little more freedom in terms of design. However, if they do not match, they should at least be in theme with one another. A consistent design style should flow through your home.

For example, your kitchen may have white cabinetry with timber-look accents. It would be perfectly OK to reverse this and have the same timber-look in the kitchen for the laundry cabinets, with white accents.
