Which Composting Toilet Is Best? Virro Renew vs Nature's Head, Airhead, OGO and More (2026)

Robauto Team · Published Nov 13, 2026 · Last updated Nov 13, 2026

We checked Virro's comparison chart against official brand sites. Here's who should buy Renew, Nature's Head, Air Head, OGO, or a dry-flush, plus limited Early50 and CyberMonday codes.

There is no single “best” composting toilet for every bathroom. The right one fits your space, matches how often you can empty it, and handles urine the way you actually live. We started with Virro’s own comparison chart and then checked current prices and key specs on each brand’s official site on November 13, 2026. Where a brand’s site disagrees with the chart, we use the official figure and say so. Feature checkmarks below come from that chart, which also notes that some features are optional add-ons and that category prices are averages and can change.

The short version: Virro’s Renew is the most feature-complete residential-style option here, and the only one whose official pages describe installing over a standard toilet flange. Nature’s Head and Air Head Classic still lead on solids capacity and warranty length. OGO Origin is the compact, push-button pick. Dry-flush, bag, and cassette toilets solve a different job.

Cassette figures are Virro’s category averages only, not a verified official list price for one model.

Virro Renew: the residential-style pick, with current coupon codes

The Renew Compost Toilet — Manual is $999. Renew Electric is $1,149, and Renew Flex is $1,249, matching the chart’s $999–$1,249 range. All three are waterless and source-separating, with a 45-plus-use solids cycle, three colors (Fresh White, Slate Gray, and Soft Black), and a three-year warranty that includes electrical parts (Virro model comparison).

Virro’s launch post says Renew can sit on an existing toilet drain flange, with urine sent to the drain or stored in the optional 2.3-gallon bottle. Every model includes a continuous 12V aeration fan (about 0.02A), an active carbon filter on the exhaust, and, on official pages, a urine full-sensor. Flex includes both urine options plus both a hand crank and powered mixing.

Dimensions need a careful reading. The Manual product page currently lists 17.5–18.5 × 19.5 × 20 inches, with an 18.75-inch seat height, and 34 pounds empty (35 pounds for Electric and Flex on the same table). Virro’s compare-models page and FAQ still list 16.5 × 19.5 × 20.5 inches and 34 pounds. The chart listed 32 pounds and 18.75 × 19.5 × 17.5 inches. Measure your space and confirm current dimensions with Virro before you order. As of November 13, 2026, the product page estimates first units will ship at the end of November, with phased production resuming in 2027.

Virro also has a limited number of promotional codes for Renew: Early50 for 50% off, and CyberMonday for $100 off. Both are limited, while supplies last; check the discount at checkout, and confirm the final price before you pay. We are not publishing an expiry date. Shop the Renew Manual at virrolife.com.

Nature’s Head: the high-capacity workhorse

Nature’s Head prices its standard composting toilet at $965, matching the chart. Official solids capacity is 60–80 uses, or about a month for two people — the chart’s “60 uses” is the low end of that range. The liquids bottle is 2.2 gallons. Agitation is manual. The unit weighs 23 pounds empty, measures 21 × 19 × 19 inches with the Spider handle (20 inches wide with the Foot Spider), and carries a five-year warranty.

That mix makes Nature’s Head a strong choice for full-time off-grid living. Diverter models and a shorter Weekender are also $965. The chart credited it with a deep urine diverter and manual agitation; the official lineup supports that. We did not find a urine-level sensor listed as standard on the main Nature’s Head page.

Air Head Classic: customizable for boats and RVs

Air Head Classic is $1,095, matching the chart, and has been sold since 2001. The official page rates the 5-gallon solids tank at up to 80 uses, so the chart’s 60-use figure is conservative. Liquids are a 2-gallon standard bottle or a 1-gallon compact bottle. Mixing is a manual crank; you choose left or right when you order, and that side is fixed after installation.

Official dimension drawings for the Classic with the comfort seat show about 18.76 inches of overall width including the crank, a 19.00-inch seat depth, a 17.50-inch base depth, and a 19.75-inch height. Buyers can pick a household or marine seat, a flat-back or hull-shaped tank, and fan-housing options — useful on boats and in wet heads. Air Head publishes a five-year limited warranty.

OGO Origin: small footprint, electric mixing, a full-bottle light

OGO Origin lists at $984.99 (the chart rounded to $985). Official specs are a 16 × 15 × 18.375-inch footprint, 28 pounds, a 2.4-gallon urine bottle, and about 25–30 solid uses — the chart listed 25. A push-button electric agitator runs a cycle of about 45 seconds, and a liquid sensor lights when the bottle is nearly full (OGO feature page).

The Virro chart only checked OGO for the urine storage sensor. OGO’s own site also describes a patented trap-door that diverts urine from solids, so that official feature belongs on the record. Warranty is three years. Origin fits best when the bathroom is tiny and you want one-button mixing more than a 60-use solids bin.

Dry-flush, bag, and cassette toilets: useful, but different jobs

These belong on a buyer’s radar, but they are not composting toilets with a mixing chamber and a bulking medium.

Laveo by Dry Flush seals waste in a twist-liner cartridge. The official U.S. DF1045 package with battery and charger is $1,045 in white and $1,125 in black, below the chart’s $1,225. Capacity is up to 15 powered flushes per cartridge, matching the chart, with no urine jug, dimensions of 20 × 18 × 16 inches, and a two-year limited warranty.

For bag toilets, the Virro chart lists a category average of $599, about 15 uses, and a 1.3-gallon jug. An official example, Compo Closet’s Cuddy Lite, is $650, with 8–12 uses per bag and a 1.7-gallon bottle, and no agitator. Cassette toilets, on the chart, average about $1,130 and about 30 uses and typically empty at a dump station. That $1,130 figure stays attributed to Virro’s average.

Who should buy which

Choose Renew if you want a residential-height seat, color options, a urine sensor, a carbon-filtered fan, and a standard-flange or 2.3-gallon-bottle setup. Pick Manual, Electric, or Flex, then check the Renew Manual page for shipping and the Early50 or CyberMonday codes at checkout.
Choose Nature’s Head if maximum solids capacity, a five-year warranty, and a lighter 23-pound shell matter more than electric mixing or a flange install.
Choose Air Head Classic for a customizable marine or RV fit — hull-shaped tank, wet-head seals, crank side, and seat style — plus up to 80 solid uses.
Choose OGO Origin if the room is tight and you want electric agitation plus a bottle-full light, and you can empty solids about every 25–30 uses.
Choose dry-flush for sealed cartridges, a bag toilet for a simpler short-trip setup, or a cassette if dump stations are already part of how you travel.

A buyer’s checklist

Measure width, depth, height, and rear clearance, including the lid and any crank handle.
Decide how urine will leave the toilet: internal bottle, existing drain, or an external tank.
Be honest about emptying: 25 uses, 45 uses, and 60–80 uses are very different routines for two people.
Check 12V fan or mixing power, warranty length, stock or ship dates, and ongoing costs such as coco coir or refill cartridges.
If you are replacing a household toilet, ask whether the unit can sit on a standard flange.
Look up local disposal rules, and if you use a coupon, confirm the discount at checkout before you pay.

FAQ

Which composting toilet is best in 2026?

It depends on the job. Renew is the strongest residential-style option here if you want flange installation, color choices, a urine sensor, and manual or electric mixing. Nature’s Head and Air Head Classic lead on official solids capacity and a five-year warranty. OGO Origin is better in a very small van. No model wins every column.

How much is the Virro Renew, and what do Early50 and CyberMonday do?

Official prices on November 13, 2026, are $999 for Manual, $1,149 for Electric, and $1,249 for Flex. A limited number of 50%-off coupons use the code Early50, and a $100-off coupon uses the code CyberMonday. Both are while supplies last; check the discount at checkout. We are not stating an expiry date.

How often do you empty a composting toilet?

Official solids figures here range from about 25–30 uses (OGO Origin) to 45-plus (Renew) to 60–80 (Nature’s Head and Air Head Classic). Urine bottles usually need emptying every one to several days.

Do composting toilets smell?

A well-maintained urine-diverting toilet should not smell like a sewer. Odor usually means urine reached the solids, the vent fan is blocked or off, or the chamber is too wet. See Virro’s odor-control explainer.

Can Renew install on a standard toilet flange?

Yes, according to Virro. Confirm fitment for your flange and floor before you buy.

How is Nature’s Head different from Air Head, OGO, and Renew?

Nature’s Head and Air Head Classic are manual-mix, high-capacity toilets with five-year warranties. OGO Origin is smaller, mixes electrically, and includes a bottle-full light. Renew sits in the middle on capacity and adds a standard seat, color choices, flange installation, and a choice of mixing method and bottle or drain urine handling.

Is a dry-flush or cassette toilet a composting toilet?

No. A dry-flush toilet seals waste in a liner or cartridge. A cassette toilet uses a removable holding tank. Composting toilets separate liquids and solids and use a carbon medium and air so solids can dry and break down.

The Robauto takeaway

Capacity, warranty, and customization still favor Nature’s Head and Air Head Classic. Renew is the one to look at if you want a household-like seat, color options, flange installation, and flexible mixing and urine setups — especially if a limited Early50 or CyberMonday code applies at checkout. OGO is the compact electric alternative, and dry-flush or bag toilets are better when you do not want to compost at all.
