Stack your washer and dryer like @emilyjacks to maximize space in your laundry room. Some other design details in her space include: Electrolux appliances in titanium, all-white cabinets with chrome hardware, and a nook for folding and hanging.
Cons to Main Floor Laundry Rooms: Noise and vibration require extra insulation and a motion-arresting pad. Leaks can damage first-floor rooms. Closet installation requires a vented door and additional space around stacked machines to dissipate dryer heat. Suggest auto shutoff valve (Floodstop $145) & washer drain pan (1-2-3 Under Washer Tray)
