My reptile room is my bedroom...though I only have 4 Leos and a [young] JCP so it's pretty cluttered in here, but at least my bed and dresser still fit XD I gotta keep the reptiles in my room anyways since the cat is roaming around...my room is considerably warmer than the rest of the house...awesome in the winter, sucks in the summer, lol. I'm moving on up to PVC enclosures over the tanks and tub I have now though, so things should get better.
...And yea, I'm still living at home, but been looking for apartments with 1 or 2 extra rooms in them even though I'm single, for expansion and stuff :p And having peace and quiet in my bedroom then might be possible; I swear the Leos time their sheds to my sleep schedule, rofl
*edit* derp, totally went off topic from the original post, but I'm not sure how big my room is, but it's not very high [a bit higher than the height of a regular door, about 7' ^^;] I think my room is about 11' by 11' or something, approximating because I have a mini measuring tape in my room right now that only goes up to 6' XD
