Bidet.

Yeah. I said it.

LSD

Blackout curtains in combination with a sunlight alarm clock to fall asleep more easily and wake up gentler without my phone.

A microwave sandwich griller. I saw one recommended on another of this type thread, so I gave it a try. You can’t believe how great this thing is. When I worked in an office, I had grilled sandwiches several times a week, and I still use it at home all the time.

A Game Genie

Low-profile noise-cancelling earbuds. Lived with a snoring roommate for some months, don't know how I would've slept without those.

Noise canceling headphones. Yes, they exist for under $100, maybe not the best, but they’re a godsend.

One of those flip boards for folding shirts, especially if you’re adhd, it makes it so you can neatly fold them and still see the front of the shirt so no more unfolding a bunch of things to check if it’s what you want and then just get left there unfolded

Eyeing a rice cooker, it's really not a need-to-have but I might go for it...

Shower curtain with pockets. Never again will you knock bottles off of those inadequate shelves.
