No, not all kitchens have a washer and dryer. In fact, it's relatively uncommon to find a washer and dryer in a standard residential kitchen. In most homes, the washer and dryer are usually located in a separate area, such as a laundry room or a utility room.
The kitchen is typically designed for food preparation and cooking, and it typically includes appliances like a stove, oven, refrigerator, and sink. While some modern homes may have a combination washer-dryer unit or a compact laundry station tucked away in the kitchen, it is not the norm.
As mentioned earlier, the washer and dryer are commonly found in dedicated laundry rooms, utility rooms, basements, or even in a closet or separate area specifically designated for laundry purposes. This separation helps keep laundry tasks and appliances separate from the food preparation and cooking areas, maintaining cleanliness and organization in the kitchen space.
