Composting & Alternative Toilets
Rough-ins, vent stacks, and service for composting toilets and other low/no-water fixtures.
About this service
Composting and low-water toilets are a real answer for cabins with limited water, no septic capacity, or strict watershed rules. We rough them in, vent them properly, and service the ones that have been in service for a while.
Signs it's time to call
- Existing composting unit smells, vents poorly, or won't drain leachate.
- New build where a conventional toilet isn't an option.
- Switching from a portable to a permanent dry toilet.
- You inherited a system and have no idea how to maintain it.
How we approach it
- Spec the right unit for the cabin's use and climate.
- Run proper vent stack and leachate drain to keep the unit working as designed.
- Service: fan replacement, drain clearing, cleanout of full chambers.
- Walk you through ongoing maintenance so it stays a non-issue.
Common Questions
Do composting toilets actually work?
Yes, when properly sized, vented, and used. Cabin owners who follow the unit's instructions get a near-odorless system that handles their use. Misused or under-vented units smell — same as any toilet.
Are they legal in Idaho?
Composting toilets are allowed in many situations as part of an approved wastewater plan — but greywater from sinks, showers, and laundry still has to go somewhere compliant. We coordinate with the health district on the full picture.
What's the difference between self-contained and central composting toilets?
Self-contained units have the composting chamber under or behind the toilet — simpler, but capacity is limited. Central units use a remote large composting tank in a basement or vented chase — much higher capacity, more flexibility, more install work.
How often do I have to empty it?
Depends on capacity and use. A self-contained unit might need attention every few weeks of full-time use. Central systems can go a year or more between cleanouts.
Do composting toilets smell?
When properly vented (with the manufacturer's fan running continuously), no — they draw air through the chamber and exhaust outside, which actually pulls odor away from the bathroom. When the fan fails or wasn't installed correctly, yes.
Do they need electricity?
Most have a small fan that draws very little power — often 12V DC, easy to run on solar. Some have a heater to speed composting that draws more. We'll size to your power system.
What about leachate?
Composting toilets produce a small amount of liquid (leachate) that needs to drain to a small soakage pit or evaporation tray. Skipping this step is the most common reason units stink. We rough in the drain when we rough in the toilet.
Can I switch to a composting toilet from a conventional flush toilet?
Yes, but you still need a wastewater plan for the rest of the cabin (showers, sinks). The composting toilet by itself only solves the blackwater half of the equation.
What about incinerating toilets — do you install those?
Yes, and for some cabins they're a better fit than composting (no liquids, no cleanouts, just ash). They need power, venting, and propane or electric heat. We'll talk through whether it fits your situation.
What ongoing maintenance is required?
Manufacturer-specific, but generally: keep the fan running, add bulking material (peat, coconut coir) as instructed, empty the finished compost chamber on schedule, and clear leachate drains annually. We can fold it into a seasonal service.
