Who Can Use Dry Flush Toilets?
Dry flush toilets like our S1 Dry Flush Sealing Toilet are perfect for RVs, vanlife, cabins, boats, tiny homes, and more.
They’re designed to be easy to use, easy to clean, and completely water-free, with mechanical sealing mechanisms that lock away solids instantly and keep odors at bay, especially thanks to the urine diversion system that separates liquids from solids
We have good news! You can convert your Cuddy or Cuddy Lite toilet into a dry flush toilet with our S1 Dry Flush Adapter Kit.
Our plug-and-play kit comes with an S1 sealing mechanism, solids bin, battery pack, control panel with housing, power connector, and power cable (adapter not included).
A dry flush toilet is a type of portable toilet that operates without water, chemicals, or composting.
Instead of using water to flush and move contents to a holding tank, it uses a dry system like a bagging or sealing mechanism, sometimes powered by a compressed air system, to encapsulate and isolate waste immediately after use.
Our S1 Dry Flush Sealing Toilet is a perfect example of a true dry flush toilet. It’s portable, eco-friendly, and ideal for off-grid living.
Not all dry flush toilets work the same way. Broadly, there are two main types:
These use a clever mechanical or air-powered system to wrap, seal, or compress each “flush” into a tough liner or bag. Each use is individually sealed off, keeping odors locked away and making disposal a breeze.
The S1 Dry Flush Sealing Toilet even separates liquids from solids before sealing, reducing bag use, smell and mess.
Some dry flush designs use preloaded cartridges with multiple sealed liners or pouches. Each time you “flush,” a new section of liner is advanced and sealed. When the cartridge is full, you simply remove and replace it.
While convenient, these systems create more plastic waste since you have to “flush” with every use, even for #1’s.
Both types are waterless, chemical-free (if you want them to be), and some models are portable.
The S1 isn’t just another dry flush toilet. It’s the first to combine push-button sealing with urine diversion, keeping things cleaner, drier, and smell-free.
Unlike other systems that rely on harsh chemical powders to mask moisture and odor, the S1 needs none of it. No powders, no chemicals, no guesswork. Our built-in separation and sealing system locks solids in an odor-proof liner. No mixing, no mess, and nothing extra to pack.
Cleaner. Simpler. Smarter.
Not if they’re well designed—like the S1. Sealing or separating mechanisms prevent odors from escaping.
Absolutely! The S1 was practically made for it. It’s compact, portable, and doesn’t need hookups.
No. Dry flush = sealing toilet that seals waste for disposal. Composting = begins breakdown but needs time to become compost.
Yes, but always check local disposal rules, especially for bagged matter.
If you’re dreaming of a bathroom setup that’s clean, odor-free, and totally independent from plumbing or power grids, a dry flush toilet might just be your perfect throne.
