Well the bath and the bin were things I went out and bought after I had a baby, because I recognized a need for them - and I used the hell out of both.
A snow suit/pram suit was essential, because it would get really cold where we lived. Like, -25C cold. So, snow suit and blanket. I could have used the wipe warmer, for the same reason; our bathroom had no heat and very, very cold wipes probably aren't much fun.
And I LOATHE sleep suits. Has anybody who inflicts them on their baby ever tried sleeping in footed pajamas? Try it once and you'll never put your child in one again. When I see a baby wearing one I assume wonder if the parent just couldn't be bothered dressing them. A simple dress in the summer, or leggings and a top, is easier and probably a lot more comfortable.
