Well when I started with GTPs last year I looked all over for a "How to" on the right way to set up a GTP Neonate tub. I found nothing. Sooo I figured I would show people in a step by step tutorial. This setup holds humidity well, is easy to maintain and makes the neo comfortable. So here you go:
First off get what you need:
Supplies:
- 6.5 quart plastic shoebox tub(rubbermaid, iris, KIS, sterilite)
- At least 2 Plastic hangers

Ok lets get started. You have your tub:

Spider man not included, my son helped)
Drill 3/16" holes all around the rim of the tub about an inch from the top and 1.5" between each hole. Shave the excess plastic off with a razor or Xacto

Cut the coat hangers down to size so they fit snug in the tub length-wise and side to side. I use 2 long ones and 2 short ones to make a tic-tac-toe pattern for my tubs, it makes it more stable and easier to handle. Not to mention it gives the snake options. It should fit snug about 2.5" down from the top(about in the middle of the tub)

I added a little bit of silk foliage to make it more cozy and it just looks cooler.
Its good to have a helper

Then the last thing you need is to drill a hole for your thermostat probe and viola!! I will be adding pictures of how I heat it once I get the UTH.
Thanks! Hope this helps someone in the future!!!
