Need tips on cooling laundry room without AC

Like title says, our laundry room seems to have been an addition at some point and never had central air put in. It is the furthest room from the AC unit and not practical to add supply and return vents. It’s a very old home and our energy costs are out the arse as it is. The window in there is also an old bay window and not sealed very well so on top of no AC it also practically trends with the outside temperature. Being in Louisiana it gets particularly hot in there in warm months. Combine that with the fact that laundry is done in there and you’ve got a very humid space. My issue is it is way too small to justify a mini split although it couldn’t be a much easier place to put one. Has a great discrete wall space for it, outside the wall is a patch of grass no one really sees and already has electric meter, sprinkler control box, and the breaker box for the whole house is in the room itself. Problem is it’s only about 50 square feet. Way small for a mini split.

I suppose I could do a mini split and instead of always having to close the doors to the laundry to not affect the kitchen cooling etc, maybe the mini split would contribute to cooling and heating that part of the house better. The window will undoubtedly need to be updated at some point, it’s not sealed hardly and not really doing any good. First and foremost I need to remove hot, humid air and then focus on cooling and heating. I’ve considered a through the wall transfer fan, exhaust fans, portable AC, etc. What do y’all think? There’s not a great spot for a room to room transfer fan without looking like shite on the wall of our kitchen.
