I am gearing up to buy my first BP and bought a tub which is big enough for an adult. I had intended to use a divider of sorts to halve the size of the tub for a juvenile and then remove the divider as it got larger. But now I'm wondering if I should have just bought a smaller tub. The dimensions of the one I have are 19"L x15"W x12"H (46qt, but it's pretty deep instead of long.)
I would be using a hard plastic sheet like PVC as the divider and potentially use small PVC tubes as backing if the little bugger decides it wants to push on it a lot.
I do have literally everything else I need for the enclosure, 2 tiny hides and 2 medium hides, heating pad, thermostat, water bowl, etc. and I bought a couple dollar store pillow cases that I cut up to make a sort of darkening drape for the enclosure since it's going to be sitting close to my PC as it's nice and warm in my room due to the electronics and no central AC. I mostly use headphones so noise won't be too much of an issue except for my own voice. I can include pictures later if it would help get an idea for anyone who would like to help. Currently taking a 15 minute break from cleaning up around the house.

Thanks in advance!
