Washer and dryer hookups (water, electric, vent) should be located so the washing machine can be on the left & the dryer on the right. Most front-load washer doors swing open to the left and can’t be reversed. If you have two front-load machines (ideal for universal design), the doors need to open away from each other so it’s easy to move clothes between each. If the doors open toward each other, they’re going to get in the way.
The majority of front-load washers do not have reversible doors.
