Structure Kit with Nature’s Head® Through-the-Floor Urine Diverter Toilet

Upgrade your off-grid sanitation setup with the Structure Kit featuring the Nature’s Head® Through-the-Floor Urine Diverter Toilet. Designed specifically for installations in tiny homes, cabins, outhouses, and other permanent structures, this complete kit includes essential components for a smooth installation and dependable long-term performance.

The Through-the-Floor Urine Diverter Toilet is ideal for installations where urine needs to be routed below the toilet to an external holding tank, approved liquid waste system, or a gray water tank already in use for shower or sink water. This model features a straight urine outlet that routes only liquid waste directly from the urine spout down through the floor of the installation. Solid waste remains contained in the composting chamber, where it is mixed with peat moss or coconut coir using the agitator handle.

User-supplied plumbing is required to connect the toilet’s flange connection to the user’s external tank or approved liquid waste system. Installation is made simple with the included template, which helps guide placement for drilling through the floor. A 1-3/4" hole saw is required to create the floor opening and is not included.

An easy-to-install cover is included to help conceal the plumbing for a clean, finished appearance. Mounting hardware for the cover is also included.

Whether you're outfitting a new build or upgrading an existing off-grid setup, this kit provides essential components—including ventilation hardware, composting medium, and power accessories—so you can install with confidence and get up and running quickly.
