I have a carriage house with no plumbing. As this is the place that I do my woodworking, I wanted to install plumbing and sewer. The problem is that there is no close sewer and the expence to put in a septic (in the city) is prohibitive. I wonder if anyone has any experience with the advertised chemical or incinerating toilets? I wonder specifically about code problems, odor problems or any other concerns that you might share.
