That's right. The Asko is designed to fit under a kitchen counter, european style.
I believe the washtub capacity is 2.1 cu.ft if I remember right. Most European style machines (Unless they're LG) are typically between 1.7 and 2.2 cu.ft.
Whereas my Huebsch is 3.3 cu.ft, which is modest in the world of the North American front loader.
Yes, they require a 220v hookup, but for the North American market, the dryer has the power supply for the washer, you only connect the dryer up to the dryer outlet.
Unfortunately, I suspect that means there isn't a gas model of the dryer. :/ (I'm not sure though.)
IMHO, for a single person or two person family, a 24" Euro Style machine is perfect. A 27" machine is better for a medium to large sized family.
