I got a bunch of stuff for my new B that I think you might find handy (all of which I got on Amazon):
Collapsible stuff - you can get most anything in a collapsible form these days. They are made out of silicone.
I also got a towel bar, knife holder and bag storage:
Paper towel holder, magnetic spice rack and soap dispenser:
Hanging clothes hamper:
And stuff for the bath - toilet paper holder, magnetic brush, suction cup towel bar and a soap dispenser:
