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

Introducing the Nature’s Head® Through-the-Floor Urine Diverter Toilet, a reliable and convenient waterless sanitation solution designed for RVs, vans, cabins, tiny homes, off-grid homes, and more where liquid waste needs to be routed away from the toilet.

Based on the proven Nature’s Head® composting toilet design, this model separates liquid and solid waste to support efficient composting, reduce odors, and simplify maintenance. Solid waste remains contained in the composting chamber, where it is mixed with peat moss or coconut coir using the agitator handle. Only the urine is routed elsewhere.

Unlike the standard urine bottle configuration, this version features a straight through-the-floor urine diverter outlet that routes liquid waste directly from the urine spout down through the floor of the installation. This makes it ideal for users who want to direct urine to an external holding tank, gray water system, or other approved liquid waste containment setup while keeping the proven Nature’s Head® solid waste composting system unchanged.

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.

Weighing just 23 lbs and measuring 21"H × 20"W × 19"D, the Nature’s Head® composting toilet is compact, lightweight, and easy to install in small spaces. Each unit features a durable agitator handle available in two options. The Spider Handle is designed to be spun comfortably by hand and includes plastic knobs for easy grip. The Foot Spider Handle features looped handle ends that allow the agitator to be operated by hand or foot for added convenience.

The Nature’s Head® design separates liquid and solid waste to support composting and help reduce odors. The solids bin holds approximately 60–80 solid uses before emptying, depending on conditions and composting medium.

Built to withstand demanding environments, the Nature’s Head® Through-the-Floor Urine Diverter Toilet provides a durable, eco-friendly sanitation solution for off-grid and mobile living. It offers the same trusted composting performance as the standard Nature’s Head® model while eliminating the need to empty a urine bottle in installations where an external liquid waste system is preferred.
