You have to buy a kiddie pool from the Sporting Goods store in JT Ult, then go back to your dorm room and put on swimwear. Then when you go to stream on Niche it should give you the option to do a hot tub stream.
It just says I'm not wearing a bottom, I've tried a one-piece and a bikini and neither work. And yes, I've got the pool.
Just tried it in game and it worked fine for me, sounds like you've encountered a bug!
After doing a stream playing video games the viewers suggested it and now I can freely do this type of stream, thanks for the help. :D
