Spa Theme Parks in the US?

I love Safiya's spa theme park videos and so badly want to experience them for myself someday. Until I have the funds to travel internationally, I've been trying to find similar places in the US without much luck. Does anyone know of any spa theme parks/ resorts in the US that are even remotely similar to the ones Safiya went to in Japan and China?

Or even any spa resorts that are less click- baity but have unique treatments, baths, saunas, etc.?
