6 Quart tub?

So, I know that baby western hoggies need very small enclosures. How would you heat a 6 quart tub?
Is there any way to get a UTH off of the bottom of a tank, or would I need to keep buying new ones? I know different sized enclosures need different sized UTH's, but if I got one sized for a 20 gallon long, could I put part of the UT on the bottom of the tub and than when the snake isbig enough, remove it and put the whole UTH on the 20? Sorry if its confusing:O

My advice is go on Reptile Basics website and buy a ultratherm UTH 11 X 6 , it will work for you tub and later own with you permanent enclosure. They don't stick and are very sturdy which is ideal if you move them around, and of course do not forget a thermostat.
