When we started the basement apartment project, I had a wishlist of stuff like towel warmer (because otherwise towels get mildewed if you don’t hang them out properly) and a vent in the kitchenette.
But everything is like $1000 each and we’re using the downstairs as an infrequently used guest space, and more stuff means more stuff that can break down the road, so now I’m not sure about all the extras anymore.
I’ve had a black&decker dustbuster just for cat litter for maybe five years? I picked it because it seemed less likely to be ruined by litter dust and so far it’s been a champ.
I recommend a 2-in-1 that converts from hand vac to cordless stick vac. I can’t recommend my Electrolux (it’s…ok.) The Bissel Ion looks nice? Kinda pricey though, iirc.
I door-in-door refrigerator. I mean, almost any newer fridge would be an improvement, I hate my fridge. But I realllllllly like this door-in-door thing. Very handy when you live with kids.
I bought a cheap plastic one the second year I canned and I couldn’t believe how much easier it made everything. Like, so much faster, so much less mess.
