I'm planning to make a tub & rack system for my snakes.

Due to limited access to the tubs like what your guys use or even rubbermaid tubs. The one which is the biggest (and fitting to my application) i found in my department store a tub about 30 inch x 18 inch x 5 inch.

Im worrying if 5 inch tub height would be an issue.

What are your recommended tub height? Will 5 inch be fine? or should i find a taller one say 6 or 7 inch height?
