Before we delve deeper into this new trend, what is a kitchenette? It is a simple small kitchen used for basic food and beverage preparation activities.
Basement kitchenettes are starting to gain popularity as more and more basements are turned into warm living areas. We are seeing many homeowners including a kitchenette or some type of beverage center in their basement renovation plans.
In almost all cases, a basement kitchenette is a small part of a larger basement living area. For example, you might have a family room in the basement with a kitchenette built at one end. Maybe you have a theater area with a kitchenette nearby where the family can enjoy some refreshments; or even a guest bedroom with a kitchenette–giving the occupant some additional privacy and saving them the trouble of using the main kitchen. It could also be part of an entertainment area, or a basement bar or anything else you have in mind.
