well, other than directly bathing/ soaking in natural hot springs
on the spot worldwide, the same piping method can be said for
commercial hot springs such as in Japan/ Korea/ Taiwan where hot
springs are piped to divert/ channel the water to commercial spas/
bath houses...
I mean it dun have the hot spring feel mah. I go there, it feels
like hot water coming out from the tap, like your home de shower
heater
