The Four Seasons on the Big Island debuted their new spa, and it is really well done. They have a communal outdoor waiting area in a garden –

There are many outdoor massage rooms, some with outdoor showers. Inside, they have what they’re calling the Apothecary – see photo below. The idea is that you choose the items for your scrub or wrap from all the jars on the shelves – most items are indigenous to this area — and they custom-mix it for you right there. My wrap was with volcanic mud, lava salt, and coconut.
