1. Make three slots (whites, colors, baby clothes) in higher part of the wall between the bathroom and the laundry room.

2. Get three high plastic boxes. Set one below every slot. Make a big hole at lower part of every box. That's a washing queue for every kind of clothing.

3. Place a combo washer dryer below boxes to make loading efficient. Place also something like washing powder dispenser right above the detergent drawer of the machine.

4. Use the laundry room also as a walk-in closet. So you can hang clothes straight from the machine.

Sorting is done by slots. Instead of folding use cloth hangers. Ironing is mostly done by the dryer.
