The Leaders in RV Sanitation 

When it comes to RV sanitation, two names consistently sit on the throne: Dometic and Thetford. And it’s not by accident.

​

Both brands have decades of experience designing toilets, tanks, and sanitation systems that are built specifically for life on the road—tight spaces, limited water, constant movement, and heavy daily use. They don’t repurpose household plumbing; they engineer solutions for RVs.

​

What truly sets Dometic and Thetford apart is their balance of durability, serviceability, and support. Their toilets are designed to be repaired, not replaced. That means clearly defined model lines, long-running product support, and readily available replacement parts—something RV owners don’t fully appreciate until a seal, valve, or pedal fails at a campground.

​

From Dometic’s sturdy gravity-flush and porcelain designs to Thetford’s industry-leading Aqua-Magic, Tecma, and sanitation chemical systems, these brands have earned trust by being reliable when it matters most. They dominate not because they’re flashy—but because they work, they last, and they’re backed by massive ecosystems of parts, diagrams, and real-world know-how.

​

In the RV world, sanitation isn’t optional—and when things go wrong, you want the brands that have already solved the problem a thousand times.

​

That’s why Dometic and Thetford remain the undisputed kings of RV sanitation.
