The main advantage of a stackable washer and dryer is that the units take up less space. Other advantages include using less water, lowering the utility bill and operating in a quieter manner.
Traditional washers and dryers can take up to double the ground space of stackables. In many apartments and condominiums, tenants simply don't have the room for them. Purchasing a stackable washer and dryer can be a great alternative to using a laundromat or the common area for washing clothes.
Some potential disadvantages of a stackable washer and dryer set are that they often come with fewer options, and the height of a stackable dryer may be inconvenient for some people.
