This is how a tub set up works.
You get a tub (if you aren't getting a rack then it also needs a good tight fitting lid)
Use a soldering iron, drill, or anything else that can poke holes in the tub. These holes let air in and help to regulate humidity.
You will need a UTH that covers approxametly 1/3 of the bottom of the tub. This will create the hot side. The UTH must be regulated by a thermostat. If money is tight you can get a hydrofarm thermostat for $30 but there are far better thermostats like the Herpstat.
The thermostat probe needs to be attached to the UTH or inside the tub. Regardless it needs to be secured so it can't move. I use hot glue for this. Just don't put any on the probe itself. Also do not use aluminum tape as it can mess with the probes readings.
Next you put your substrate in the tub, I would sugest newspaper or something similar.
You will need 2 hides. 1 that goes over the UTH and the other goes on the cool side.
You place a water bowel in the middle.
You should also have a thermometer/hydrometer in the tub. You can get this one at Wall*Mart for $12:

Just a quick note I really don't recomend using a tub if you will still be keeping a snake in your garage. I really don't think any set up will work but UTH's don't really effect air temperature so if it gets cold you will have problems.
