Where can I find this video?

Her name is Lay The Kat. I am assuming by your question of where can you find a video of the video you posted that you either want a full length or where you can buy the original maybe? She usually only does short clips 5-10 minutes each. The direct answer to your question is that you can only by the full length from her current employer.
She works for 18onlygirls now and has sold her website laythekat,com to them as well. It is a very high quality site and I downloaded 1 terabyte of HD movies from them for $28 in a month with lots of scenes from Kat. The answer to your question therefore is to go to this site and buy a 1 month membership:
http://www.18onlygirls.com

To search for her videos available on 18onlygirls, of which there are many different scenes of her in a bathtub, you can find a Directory listing of her scenes at:

as far as the video, which is confusing because you posted a video already. Here is another version of that scene:
