Tank size

[TGC]

Hi i would like to ask, will my tank:
24" X 18" X 18"
Be large enough for my male ball python, when he is an adult?
Currently he is 24" long and it seems just fine for him..

Additionally, I would like to know, what size hide will be required for an adult male ball python?

Please keep in mind for the hides, i have this terrarium in my bedroom and i would like it to look attractive. Therefore, i am not open to the idea of using plastic containers as hides. If there is an exo-terra product (like one of those caves they sell) that would be suitable for an adult male python, please just let me know.. and possibly show me a link to where i can buy one.
I would like to get all the extra stuff ready for when i will inevitably need it, when my snake grows bigger.


-thanks.
