"I knew I wanted a permanent shower, for sure!" Hall told Insider. "Some vans have pop-up showers, outdoor showers, and all kinds of creative ways to bathe, but I knew I wanted a permanent built-in shower."
She bought a self-drying and self-cleaning shower door that retracts into a vertical box, which makes it look like a pocket door. Hall said there's a squeegee along the height of it that removes water as it retracts to limit mold production.
She felt the same about a toilet, saying that she "didn't want to be pulling out a plastic toilet from under my kitchen sink."
Hall told Insider she installed a C-Head composting toilet, which uses a fiber medium like coconut husks or sawdust to mask the odor of solid waste. Liquids are typically separated into a bottle or jug, but Hall modified the system to have it drain directly into the waste water tank she installed on the bottom of her van.
"There, it's mixed with all the used shower and sink water," she said. "Liquid waste is basically sterile, and when diluted actually makes a great fertilizer! So you can dump the tank pretty much anywhere responsibly, as long as you are using biodegradable soaps and shampoos."
