Everything seem ok?

Hey,
i went to staples today and bought a 43L box, im not to sure if this is the right size because i want to fit 2 hides in a water bowl and some decoration. This is why i bought the bigger one, anyway im going to be getting a hatchling 2011 hopefully in the next few months. The measurements for the tub are, 53Cm Long, 36Cm Wide and 21Cm Deep. What do you think?
here is what i want the enclosure to look like.

converted is 20" Long 14.2" wide 8.3" deep, seems a little big for a hatchling, but with 2 hides, water bowl, some foliage, it may work.

thanks for the reply,
i think i will just fill it up with alot of decoration and maybe a few more hides if they fit.
