Attached are photos of our Nature's Head (NH) install that allow it to rotate out of the way for showering. The NH is wider than the factory head, so installing it in a fixed location was going to have an effect on some aspect of using the head/shower. Having it rotate a few inches gives a lot more usability to both.

The NH is mounted on a piece of HDPE plastic that is secured to the hull liner where the OEM head was mounted. The plastic board is held down with two washer-headed screws, one of which rides in a slot that allow the board to rotate. The NH unit is just mounted on the board with the included brackets.

I used the existing OEM flush switch wiring for the fan power. The vent hose is routed through the hole in the bulkhead where the original plumbing was. I cut a hole in the starboard side of hull about mid-way between the tank vents and the heater exhaust, where I installed a Vetus vent.

All-in-all, I haven't found anything I would change from the original design.

2 more questions: 1) did you use bolts or screws to attach the vent 2) did you use a gasket or sealant? (No, I’m not nervous about punching a hole in my new boat…much.)

Not at all.

Here is the vent I used:

I installed it so the elbow points up, creating a loop in the hose that is above the vent. Water would need to be forced pretty high into the hose before it could get past the loop. So far, it hasn't been an issue.

You'll need to remove the ceiling panels in the quarterberth (cave) to access the area where the vent will go. Once I determined where I wanted the vent to be from inside the cave, I taped a strong magent in the center of where the hole would be cut. That made it easy to use another magnet to determine where to start the hole saw from the outside of the hull. Measure 10 times, cut once...you only get one shot at it!

I seal most of my hull penetrations with Bed-it butyl tape and that's what I used for the vent. Any good marine sealant will get the job done, though. I through-bolted with stainless machine screws, which required my wife to hold the screw head while I tightened the nut from inside the hull.

One other thing I did was to seal the edges of the hole with thickened epoxy. The hull in that area is cored with plastic honeycomb, so I wanted a smooth, sealed surface where the vent would penetrate.

This is great picture, I was wondering about the core. Epoxy great idea too.
