I know this is an old thread but I wanted to throw in my $0.02, in case other newbies, like me, are browsing...
I got a tortilla warmer from WM for under $4, and it's great as a water dish, could be turned over for a hide. I just set the lid over, in case I loose the one for my actual tw for us humans.
For hides, I currently have baby wipe tubs turned over with openings cut into the sides. They are a little tall, but nice and narrow for "hugging."
