Don't use a barn door or pocket door. Use a regular door to block as much noise as possible from the washer and dryer.

What is under this bedroom? The garage?

How do you plan to vent/exhaust the dryer?

We lived in a townhouse for a year which had all of the bedrooms on the 2nd floor and a 2nd floor laundry. We found it to be really convenient. One consideration is the effect of a leak in washing machine hoses or the machine itself on the 2nd floor. Our practice is to install a Watts Intelliflow valve which will shut off water flow if a leak is detected. https://www.watts.com/our-story/brands/intelliflow

The garage is under the bedroom, and we are planning to vent it out to the overhang. Currently, it has over ten feet of venting going under the house which concerns me. I didn't think about the door for noise or leaks. I'm not sure if the contractor already took that into consideration. I am trying to figure out if it would work better upstairs because there are times I forget and change it when I am in the kitchen. However, there are plenty of times where I start it late or forget something because it is upstairs.

I've had laundry upstairs, downstairs, off the kitchen, in the basement, in the garage, off the family room . . . you name it and I've had it. The laundry room in the second floor hallway adjacent to all of the bedrooms was, by far, my favorite.

I can't help you place your laundry room in your home, but hopefully one of these smart builder-types will show up and offer you a solution. Good luck with your project, Emily.

I wonder if it is cheaper to provide maid's quarters than relocate the laundry room??

I wish! lol

Laundry up is the best. Hauling laundry up and down stairs is way worse than hauling your butt up and down stairs.

Put a reach in closet here and change the door swing.

I, too, have had laundry all over. Second floor was the worst for me personally. I have a fair amount of things that don’t go in the dryer or limited dryer time. I never hung out on the second floor so going up and down was a huge pain. Also, the W/D vibrates a fair amount despite getting the best units for that reason- the bed and wall next door vibrates and it’s annoying. Another limitation was that was required by my insurance company is the pan under the washer for leaks. I have front loaders there and I cannot use the drawers in the pedestals because of the pan. My laundry room is original to the house. One of the big fails, IMO.

A friend's house has her machines on the 2nd floor. The house was built as such, not a retrofit. I was there once when the washer was running, apparently directly above where I was sitting. The vibration and noise transmission through the floor/ceiling was surprisingly loud.

I too have had laundry both upstairs & down. When remodeling our previous home we had the laundry moved upstairs, due to the fact that I tripped & fell down the stairs while carrying a basket of laundry down. Upstairs was the BEST decision ever. Our contractor utilized part of a guest room closet & we had stackable full sized washer & dryer.. BTW, never heard any noise from the machines while downstairs.

Noise is definitely a concern. The room is used as a bonus area right now, and the other bedrooms do not share a wall with it. It is over the garage, so hopefully, no one will hear it rattle too much from below. The laundry is under the bathroom right now, and it shakes the room from the lower level. It drives me crazy. I was thinking the closet should be right inside the door or where the wall slopes. There's a small attic access there that could be concealed that my kids find creepy, lol. Or no closet? I don't know how it will alter the value of the house though.

Are there other locations on the second floor that would potentially a better location for laundry?

Do not take any design advice from anyone that suggests putting barn doors on a laundry room (although I just finished a beach cottage that has a pair of barn doors on the laundry room. I still object but sometimes I have to do what the client wants).

The barn door was my idea, and now explains why he looked confused when I suggested it. I didn't think about the noise just trying to avoid losing space with door swing.

Door swings take up about as much space as it takes to pass through the doorway.

Before you move the laundry to the second floor, you need to figure out if thats the best place for it. What time of day do you do laundry?? How much time, do you spend on the second floor, once you are up in the morning. Etc. You might find that you just want it right where it already is, for convenience and less running up and down the stairway, to change the washer and the dryer. etc. I would hate to have to go upstairs, to change laundry loads. I dont know your age either, so maybe you dont mind running up and down the steps several times a day while doing laundry.

If bedrooms are upstairs, unless you have a laundry chute you're going up and down the same amount to haul clothes. Either your butt or a basket is going with you, but it's the same up and down regardless. I don't hang out upstairs either but going up to change a load every hour isn't the worst IMO. Carrying laundry OTOH.... Sucks.
I really don't get the argument that having the laundry on the main level is less running up and down stairs.
