The floor space is 2x2,60 and you are making it smaller. And he will have only one cool hide. If he wants to use the belly heat, he does not need a hide. It won,t be that full, the hide size is 11x10 inches. And the water bowl is not that large, it is designed only for drinking not soaking 8x6,6 inches. By the way, my boa got a very big enclosure size in feet: 7,20 long, 2,60 deep, 4,60 high because i excpect him to reach the 10 feet at least as adult. He is 17 months old now and eating large rats. This is his latest feeding video: https://www.youtube.com/watch?v=-oNLd45lb2A
