The washer and dryer each stand on a pedestal with pull-out storage basket. The dryer has a left-hinged door, the washer door is hinged on the right. Between them is a counter with knee space. To the right of the dryer is a counter with a sink and knee space.
The user does the laundry independently. Placing the washer and dryer on pedestals raises them to a suitable height for the user. The family collects the dirty laundry in a laundry basket on casters (see associated tip) and the user moves the clothing from the basket into the washer. When she sits at the counter between the washer and dryer she can easily move the laundry from one appliance to the other. She transports the dry laundry on her lap to the large counter and sorts it in piles for the different family members.
It was not easy to find machines with right-hinged and left-hinged doors.
