Hello

I'm almost ready to go shopping for things to build my first snake's home, will these things be all I'll need for building a home for a young snake?

A tub 13.5 x 16 x 7 (inches)
A thermometer, hygrometer, UTH and a thermostat (what types of each of these things are the best for BPs?) - how should I put it together to work?
2 shelters, a water bowl

And for the future, would an enclosure of these measurements: 46.5 x 17 x 17 ,be enough for an adult BP?

Thank you in advance
