yes, regular bathtub. I try to get all of my body under the hot water for the 45 mins, but my knees stick out. Drain, and then I just scootch down on my back till my hinder region is under the stream of cold water out of the tap and knees are bent up above me, kinda in a fetal position on my back. So my feet and everything else are out of the water.
Yeah, it's great I haven't been cold all winter and my nerves are better...as far as not getting nervous around people, public speaking and such. But that may have to do with the lecithin.
