In this photo from the path onto our property from the south, the stone shower enclosure is on the right side of the palapa building, behind and to the right of the wheel barrow. Our well is where the pvc pipe is at the bottom of the photo. We have a pump and solar panel that will pump water whenever there is sunshine to the tank upstairs in the new palapa/bathroom. You can see the shadow of the solar panel on the grass roof. The bathroom palapa wasn't built when this was taken, but it is maybe 15 feet away from the palapa in the picture, in the trees to the left of the house. From that we will route poly pipe above ground or only slightly buried to the shower area. Excess water (overflow from the tank) will either water gardens or overflow into the cave opening to the left of the low wall on the left side of the path. A little confusing but this is the only view I could find that shows almost everything.
If you like to try to find things in pictures, see if you can find Rosaline- he has on a green shirt.
