Keeping Chameleon in Shower

[chubbs032]

What do you guys think of this idea? I plan on keeping the room temperature during the day at 78 - 82 degrees plus or minus a few degrees. Will keep a fake 4ft ficus and another 6 ft. ficus in there with vines. I will have a spotlight fixture with a mercury vapor bulb on a portion of the 6ft ficus as a basking site and a 75watt night bulb for nighttime when temperatures may go down to 68- 72. Room temp will be adjusted with a thermostat on a rheostat and timer. What do you guys think?

Currently my veiled is in a 4.5 ft x 2.5 x 2.5 reptarium and its just a chore to move him in and out to water him. He doesnt drink from a drip so i shower and spray, but the water collects at the bottom starts smelling and collecting.
