What is the Best Composting Toilet for Full-Time Living?

When it comes to full-time living—whether in a home, cabin, tiny house, or off-grid retreat—not all composting toilets are created equal. Reliability, odor control, and minimal maintenance are non-negotiables. So what should you look for when choosing the best composting toilet for everyday use?

Key Criteria for Full-Time Composting Toilet Use

1. Large Solids Capacity

One of the most important features of a composting toilet for full-time living is a large container for solids. Ideally, the toilet should only require servicing 1–5 times per year. That means fewer interruptions to your daily routine and a more comfortable, hassle-free lifestyle.

2. Odor-Free Operation

Smells are the number one concern people have about composting toilets. The best systems use passive or powered ventilation, effective liquid separation, and natural composting process to eliminate odors completely. A well-designed system should work so effectively that even guests won’t notice a difference.

3. High Reliability

Full-time living means daily use—often by more than one person. You need a composting toilet that performs day in and day out, even during peak use. Whether it’s a quiet weekend at home or you’re hosting visitors, your toilet should never be a source of stress.

4. Split-System Design (Ideal Setup)

For maximum convenience and capacity, the ideal setup includes a porcelain toilet seat in the bathroom connected to a composting unit installed below floor level—either in a basement, crawl space, or under the house. All waste drops directly into the composting chamber below, which is easy to access and service just a few times a year.

Best Composting Toilets for Full-Time Living at Waterless Toilet Shop

Several models available at Waterless Toilet Shop meet these criteria

Green Toilet Lux composting toilet

Green Toilet Lux is product family of indoor-use batch composting toilets. There are two Green Toilet Lux models: a smaller 120 and a larger 330 model. The Green Toilet Lux is a batch composting toilet which means that the product package comes with two (or more) Green Toilet composting units used one at a time. Learn more about batch composting toilets.

• Robust batch composting system
• Ventilated, odor-free, and easy to use
• Works with standard porcelain toilet
• Excellent for year-round living

Green Toilet Lux provides excellent capacity and value. The product comes with two sizable composting units, ideal for full-time living. The Green Toilet composting containers feature a double-base design that separates the excess moisture from the compost, keeping the toilet odorfree at all times.

CF composting toilets

The CF composting toilets are a group of continuous composting toilets which means that they come with a single, large composting unit fixed in place under the bathroom floor level. Unlike the Green Toilet Lux composting toilets, CF composting toilets are emptied gradually through a hatch on one side of the composting unit. The CF composting toilets  include two models: a smaller CF 4 and a larger CF 8.

• Single large underfloor composting chamber
• Ideal for homes with basement or crawl space
• Suitable for families or multiple users
• Service needed only a few times per year

The advantage of CF composting toilets is that because the composting units are fixed in place (they are not exchanged like the composting containers of the Green Toilet Lux), the composting unit can actually be half buried in ground (depending on ground conditions, of course). Thus, they require much less underfloor space compared to batch composting toilets. CF composting toilets provide tremendous capacity – yet they do not require so much underfloor clearance. For example, the CF 4 composting toilet only requires a minimum of 13 inches of underfloor space when half buried in ground.

Rota-Loo composting toilets

Rota-Loo composting toilets are special batch composting toilets that feature a unique rotating compost unit with six individual bins. Rota-Loo composting toilets provide the largest, single unit capacity, combining convenience of batch composting and low underfloor space requirement of fixed-in-place systems.

• Rotating chamber system for continuous composting
• High capacity for large family or public use
• Underfloor installation with low-maintenance design

No Underfloor Space? Here Are Your Best Alternatives

If there’s no underfloor space available, a self-contained composting toilet is the next best solution. These units are compact, easy to install, and still provide excellent odor control and reliability—especially for 1–2 full-time users.

Some of the best self-contained options include:

• Oz-e-Pod
• Green Toilet 100 Easy

If your household has 3–5 full-time users or more, we recommend reaching out to us directly. Without underfloor space, finding the right solution for heavier daily use requires a bit more planning—but we’re here to help you find the most practical, low-maintenance option for your situation.
