I have had this aloe plant for about a year. So far it has stayed in the pot it came in. It is a house plant residing in my bathroom. It sits on the ledge of a garden tub that has a sunlight. I want to repot it but not sure what the best way to go about it is.

1. What kind of pot is best....plastic, terra cotta?
2. How big of a pot shoul I use?
3. Anything else I should know?

Also, what type of aloe is this? Thanks for all your help!
