An outdoor shower-toilet enclosure is a reasonably straightforward DIY project from a carpentry-assembly viewpoint. The difficulty lies in what features to provide, particularly since not a few people (esp. women) are understandably uncomfortable with the idea of taking showers out of doors.
So, the biggest challenge is to provide a facility that ameliorates this discomfort by providing complete privacy while at the same time providing access to a surround view of Trouthaven’s vistas. So, there will be no roof and no sides so tall as to unduly obstruct the views from within the enclosure.
Here are some examples of outdoor shower-toilet enclosures I am currently contemplating. I’d be very interested in any thoughts, comments, suggestions, recommendations, or personal experiences you may wish to provide.
The shower enclosure pictured on the right is very much along the lines I favor. However, the enclosure is 4′ wide and 12′ long providing plenty of room for a dressing room, shower, and throne.
The toilet is a dry composting toilet by Nature’s Head. These toilets are very popular with the tiny homes community because there is, quite truthfully, no residual odor.
