I wouldn't use the sink because there are all sorts of chemical/soap residues in there. ...although folks use bathtubs without ill effects. Trouble with a sink also is its size and lack of a lid. LOL Squeezer (cute name!) may not want to stay in there. A big sterelite tub with a lid would work well. Make sure it can get air and the lid is secure and do not leave unattended!


As for the humid hide...opaque or dark would be best because they'll really feel like they're hiding.

You don't really know for sure if your temps are too cold because those dials just aren't accurate enough to tell. They are frequently as much as 10+ degrees off. Plus, they are measuring the part of the tank where they are stuck on...and what you want to know is the temperature of the floor of the tank where the snake is actually laying.

A UTH is usually enough to warm the hot side, and will often get TOO hot if it is not controlled with a thermostat or rheostat (dimmer switch) of some kind. Can you rest your hand on the floor of the tank over the UTH without burning yourself? If so, then I'm sure it's safe enough for now until you can get a real thermometer in there.
