Except in this case.
Until about 10 years ago, if you wanted to buy stackable laundry, this type of unit is what you would purchase
The washer and dryer unitized as one piece. It has the distinction of being more expensive to buy, less featured and more difficult to install. The Frigidaire shown is the best of this lot.
With front loaders becoming more prevalent, you can stack every unit except full size Bosch and Miele...Like this Maytag EpicZ
You can even stack this Frigidaire for under $1,000
