Why is a C-Head better than an outhouse? - For homesteaders and cabin dwellers, outhouses may be quaint and it may seem
simple in remote areas to just dig a hole in the ground, cover it with a small outhouse building and then cover the hole and move
the building when it gets full in a year or so, but consider the outhouse for a minute. It stinks, it wastes a valuable resource, it
pollutes the ground around it and worst of all, it is outside exposing you to the elements and wildlife. A BoonJon can easily be
installed inside your home or cabin. It is much less expensive and labor intensive to install; there is usually no ventilation needed;
there is no sewage smell; insects are easily controlled; the waste is available for use as valuable fertilizer in liquid and solid form; and
you can use it without having to go out into the night or bad weather. This is a no-brainer.
Is the C-Head a legal marine toilet? - Yes, the C-Head falls in the Type III MSD classification. C-Head meets and exceeds all the
criteria for a "portable" or "installed" toilet. As a portable unit, the entire unit and/or the collection containers are designed to be
easily carried on and off the boat. The waste can be removed using an attached or integrated portable rigid container and disposed
of using onshore facilities, and it does not require water or electricity from the boat. "Portable" and Type III MSD toilets do not
require certification by the USCG on pleasure craft. (
click here to read USCG reg) This allows us to customize our products for the
buyer. Portable toilets are accepted on virtually all bodies of water in the United States. They are the simplest, easiest and cheapest
method of responsible waste control and by their simplicity they encourage good environmental stewardship. All portable toilets are
required by regulation. The C-Head can be secured to the boat using any of several
quick release methods laid out in the instructions
to prevent spills in rough seas or collision.) The C-Head can be "installed" and used in conjunction with a Type III MSD holding tank
using an EUD.

What is the best way to get rid of the urine? - Mixing urine with solid waste is what creates that horrible head odor smell that
cruising boaters and RV owners are familiar with. To prevent this, separating the urine is critical, so disposing of the urine is a
necessary issue. With the C-Head you have several options that are not available with other systems. Because the C-Head uses
inexpensive and easily available one-gallon water jugs, you can first, simply fill and store gallon jugs of urine. Having them in one
gallon jugs allows you to place them in small, out-of-the-way spaces until you can empty them. A cloth grocery bag is designed to
hold two one-gallon water jugs and is a discreet way of carrying them ashore. Adding a squirt of diluted Campa-chem deodorizer to
your gallon jugs, after each use of the toilet, will eliminate all the smell completely. Pour them out in the restroom or overboard
offshore. You may also opt to use an external urine diverter (EUD). Managing urine this way is a little more work but it is worth the
trade off for total control of head odor and the convenience of not having to find a pump out or dump station. Making it part of
your daily routine will prevent overflow, which can be a problem with the other composting toilet systems. And finally, if you are
using your C-Head for weekend forays or week long cruises, you can take the urine home and dilute it 5 parts water to 1 part urine
and pour it in your flower beds or around your trees as a great fertilizer.
Can you put toilet paper inside the toilet? - I highly recommend using flushable wet wipes. These are small and do a good job
and don't fill up your toilet with paper. They are ideal for people who are used to using a bidet. You can put toilet paper inside the
toilet, however, it will fill up the toilet faster. I recommend using a small 2-gal waste basket with a lid (lined with removable, small
plastic grocery bags) if you use toilet paper. Using a waste basket for toilet paper is a common practice for people cruising and living
aboard boats and is a cultural or modesty issue rather than a health or sanitation issue. It also does not produce any noticeable odors
contrary to what one would think. You can also use paper towels instead of toilet paper if you are going to put it inside the toilet as
it will cause you to use significantly less paper overall. Simply tear the sheets into convenient, usable sizes. You cannot use flusable
wet wipes with other composting toilets.
What is an EUD and how does it work? - An EUD or external urine diverter is an accessory that you can purchase that allows
you to divert the flow of the urine outside the toilet to a larger collection container. This is very useful in applications like bunkers,
cabins, homesteads, other OTG situations with a drain field or septic field. It is also a good solution for boaters, campers, RVs and
trailers with holding tanks. Using an EUD in conjunction with a holding tank allows you to extend the use of the holding tank
between pump outs significantly. Using a well designed hybrid system of a portable toilet for solid waste and a holding tank system
for urine collection is probably the best solution for waste storage aboard a vessel, prevention of illegal waste dumping, and for odor
control and increased range of use.
Is a C-Head legal in my home? - With respect to permanent residences, codes vary, but in general, you can use a C-Head for
temporary or emergency use anywhere you are allowed to use a cassette or porta-potty type portable toilet. This might include, use
by bedridden patients, homes with overflowing septic fields, prepper bunkers, hurricanes, storms or other failed utility incidents, etc.
Using a C-Head portable composting toilet in your home is dictated by local codes. Contact your county or city authority for
information regarding the use of composting or dehydrating toilets in your area. Always dispose of waste responsibly and remain
conscious of the effects that composting of waste have on the surrounding environment. Congested or environmentally sensitive
areas are more likely to restrict the use of composting toilets.
So what are the advantages of a composting toilet over other systems? - There are several. Managing waste using the C-
Head system is cleaner than other waste management systems (including other available composting systems). Dividing the waste
helps eliminate the odor common to other systems that mix the liquid and solid waste (your local waste treatment facility is a case in
point). For boats, travel trailers and RVs, the C-Head system eliminates the use of water and frees you from the restrictions of having
to find a pump-out or dump facility or pay fees. This allows you to travel to sensitive areas on land as well as on the water, areas like
the Keys, the ICW and the nation's lakes, bays and rivers, or go "boondocking" in the national forests, uninterrupted for extended
periods of time. The C-Head is considerably less expensive to install, retrofit, repair and maintain, and it adds a beautiful and novel
feature to you boat, camper, or cabin.  
How is the C-Head different from the other compact composting toilets? - It is smaller, lighter, and the seat is larger and
positioned lower and is more comfortable. It is easier to empty, clean, maintain and operate. The waste it produces is more safely
and securely removed because it pours out easily and completely and encourages use of inexpensive rigid disposal containers for
disposal rather than plastic bags. It is far more attractive and it can be custom finished to suit your wishes. It uses non-proprietary
containers and components that are inexpensive and easily replaced. The C-Head has a double containment system to protect against
spills. It is easy to repair with minimal skills. It is more versatile in its waste storage capabilities and it is much less expensive than its
competitors. See the "C-Head
How is the C-Head portable toilet different from a so-called Porta-Potty? - The biggest difference between a C-Head and
other portable cassette type flushing and non-flushing toilets is the separation of the liquid and solid waste. Mixing the two can create
a strong odor or require the (often unsuccessful) use of strong chemicals which add to the overall cost and hazard of use. Mixing
waste also creates "effluent", a slurry of sewage that can be a disgusting chore to dispose of. A Porta-Potty will also fill up quickly
which severely limits the time it can be used and it is generally impractical for use on a cruising boat or camper for extended periods
of time.
How is it made and is the construction strong? - C-Head toilets are manufactured
from a composite of plastics, including PVC, phenolic plastic, epoxy glass and HDPE.
The toilet seat is a modified household toilet seat with heavy duty plastic hinges. The
toilet hardware and fasteners are stainless steel. The designs arecapable of supporting
more than a 300 pound person.

Don't composting toilets attract pests? - An occasional problem with composting toilets is fruit flies, sewer flies and house flies.
The Key to controlling insects is to limit the time they can occupy the toilet and this means emptying the toilet frequently. There is no
advantage to storing waste in your toilet for long periods if you have to clean up the mess insects can make. This problem is avoided
with the C-Head for several reasons. One, the C-Head is emptied more often, removing the waste from the home and any eggs and
larva before they can hatch. Two, the churning method that the C-Head uses causes almost all of the waste to leave the collection
container when dumped. Three, the C-Head housing will accommodate a "No-Pest" strip that kill any insects that enter the toilet. It
also has a basket that will hold 2 moth balls which produces a slight chemical odor but helps discourage insects.
What comes standard with every C-Head? -

The following items come standard with the C-Head.
  1. Stock or Custom portable toilet housing (primary container)
  2. Five gallon solid waste collection container with a built in churn
  3. Churn handle
  4. Gallon jug with EUD or P-tank option
  5. Ventilation hose and attachments
  6. Sealing lid - covers and seals the urine diverter (not shown)
Is the C-Head difficult to install? - No, it is not difficult. While the C-Head is both a portable or installed type toilet, the USCG
requires that all toilets be anchored to the boat in some fashion, so that they will be secure in heavy seas or collision. Common sense
would dictate that this applies to travel trailers, campers and RVs as well. There are several unique and novel ways to anchor a C-
Head toilet shown in the manual. Venting is done to control the build up of condensation inside the toilet. You may or may not
need to vent the toilet and we recommend that you wait and see if it is necessary. Venting requires running a vent hose either
outside or else into a vented locker or using passive or active air flow. A shower seal kit or shower cover is required for installation
in a shower stall where you will be sitting on the toilet to shower. Both are available as an accessory. Only one is needed. In other
applications, such as travel trailers, RVs, cabins, etc., installation is simplicity itself. Routing the vent hose will be the most challenging
aspect if needed at all. For a better understanding of venting,
go to this page.
Is the C-Head hard to use? - Not at all! It is important that the liquid and solid waste be separated as much as possible, but it takes
only one or two uses to get the "feel" of where to position yourself. Most people can just sit down and go without any issues. The C-
Head has a comfortable but unique seat that is designed to give you a better "feel" for correct positioning. It requires no adaptor seat
for children to use. It requires no coffee filter paper barriers to keep it clean. We offer a simple, inexpensive accessory that ladies can
use if they are having difficulty keeping urine out of the solid waste, which is rare. While the round toilet seat is the standard,
elongated toilet seats are available to people who prefer them.
How do you install a C-Head with a wood floor? - The C-Head is usually stabilized by docking it into a wall cabinet for use at
home. The wall cabinet holds individual charges of composting medium, cleaners, toilet tissue, hand wipes, candles, etc.
What is a ventilation hood? - The ventilation hood or vent hood is a separate appliance from the toilet itself and aids in
transferring the waste from the toilet to a separate storage bucket for storage purposes. It is primarily for live aboard boaters and
prepper bunkers. If you are not going to need to store the solid waste then you do not need the vent hood.
How long does it take to get one after you order it and is there a warranty? - All of our toilets, including custom finishes
usually ship within a day or two and arrives within 2-3 days. Shipping and handling costs are included for all 50 states including
Puerto Rico and the Virgin Islands. Florida residents pay sales tax. You can pay with a check, money order or with a credit or debit
card. A full refund is available for toilets for thirty days from the day the unit ships unless you have used or modified the toilet by
cutting holes for anchoring or ventilation. The cost of the original shipping will be deducted from the refund. The owner is
responsible for return shipping costs, including insurance. The toilet will be inspected upon receipt and any damage will be
documented and sent to you for claim purposes. We will deduct the cost of any repairs from the refund. Please repackage carefully.
Do you ship outside the United States? - Yes, we ship internationally. Contact us for a price quote. Please remember that the C-
Head uses non-proprietary containers for waste disposal that are common to the USA and Canada. We do include an additional
more durable urine container with international customers. You may have to order these products online if they are not available in
your country. Other containers may not fit as well the space allotted. Consider using the P-tank that we offer as an alternative. If you
are ordering the EUD (external urine diverter) this will not be an issue.

Online Forum Questions

Won't installing a C-Head make the value of my boat go down? - People are still learning about the advantages of
composting toilets over holding tank systems. It is a new paradigm. Head odor from existing holding tanks can be a serious problem
when it comes time to sell your boat. Head odor is the primary reason people buy a C-Head. The only person who is likely to buy a
stinky boat at the seller's price, is someone who is going to replace the current system with a composting toilet (which you could
easily suggest). If you do have a "composting" toilet at the time of the sale, you can reinstall a conventional holding tank system if
you need to, to satisfy the new owner, without having to tear out the old system or pay someone a healthy sum to do it for you.

How do you get rid of the waste? Isn't dumping bags of poop in the trash illegal? - Many, if not most local laws do allow
for the discarding of "feces contaminated waste" in the trash as long as it is sealed in some kind of plastic bag or container. This
accommodates people who discard child and adult diapers, colostomy bags, pet waste and other bodily waste of that type. The C-
Head system advocates using a 5-gal plastic bucket with a locking lid if you are going to discard it. Treat the waste with chlorine
bleach and seal it from public contact using a durable rigid 5 gallon container. (One could argue that contrary to what many people
say, placing non-biodegradable plastic buckets in the landfill is a valid and effective way to "sequester" carbon, keeping it out of the
atmosphere. If the carbon molecules it is made from are still there in a thousand years, so much the better). Treating the waste with
liquid chlorine bleach should meet and exceed the spirit of the law, since all pathogens and parasites will be killed and the waste
rendered harmless. For those owners who have the great option of storing the waste until they can compost it or manage it at home
can refer to the
BoonJon System. There are several good ways to manage your waste, either by composting, using insects to reduce
the volume, dehydrating or converting waste to bio-char.   

Aren't most of the composting toilet owners just dumping their waste overboard and polluting the environment? -
Well first, dumping your waste overboard 3 miles offshore is legal in the USA and for many people, a good way to get rid of the
waste. You risk losing half of your toilet doing that with the other composting toilets (if you accidentally drop the bottom half in the
water), but it is a reasonable solution. If however you are opposed to dumping your waste in the ocean, the beauty of the C-Head
system is that it allows you to conveniently store your waste until you can dispose of it in a way that you feel is more responsible.
Unlike the holding tank systems that become unusable when full, you can literally carry months of waste, securely stored in 5-gallon
containers, in a space smaller than your existing holding tank takes up.

With respect to illegally dumping waste, a surprisingly large number of boat owners with holding tanks dump their holding tanks
illegally, and holding tank systems are without a doubt the greatest polluters in the pleasure boating world. Some owners dump
regularly without compunction, some only in emergencies. Sometimes you arrive with an overflowing holding tank at that lone
outpost marina, just to find out that their pump-out service is "out of service" making it easy to justify a midnight dump in the minds
of many. A single illegal holding tank dump creates more bacterial pollution in 15 minutes than a C-Head owner would by pouring
just their pee overboard during the entire life of the product. But the beauty of the C-Head system is that there is no reason or
incentive for anyone to dump any of their waste. A C-Head owner can't dump solid waste material overboard without incriminating
himself, since most of the waste will float for some time creating a trail of evidence, not to mention he would have to go on deck to
do it. With holding tanks, it is much easier just to sneak below and open the Y-valve for a few minutes. The fact that there is
emergent need
to empty your waste with the C-Head system, gives the owners little reason to break the law or pollute the

Which model do I choose?

To determine which model and accessories you need, follow these guidelines.
inches overhead, you should probably order a
Basic C-Head model.
  1. If you are wanting to locate the toilet in a corner or the bow of a boat or back against the sloping hull, you should consider
    the Compact C-Head.
  2. If you are locating your toilet on top of an existing pedestal that is at least 11 inches front to back, you should consider the
    Shorty model. You may be able to extend the pedestal top out if it is under 11 inches front to back to accommodate the
    Basic C-Head or Compact C-Head model.
  3. If you have overhead space restrictions or a pedestal or you want to store the toilet in a cabinet, you should consider the
    Shorty model.
  4. If you want to pipe the urine collection out of the toilet into a tank or drain field, consider the "EUD" external urine
    diverter" (gravity feed) or if to an elevated holding tank, the "pump-out tank".
  5. If you are installing your C-Head over an existing RV or camper toilet flange and want to pipe the urine down the hole,
    consider the "BEX" (bottom-exit) kit. The BEX kit is only available with the Basic C-Head model.
  6. If you need to access behind the toilet or if you plan on using your C-Head in several different locations, consider using the
    "rubber latch tie-down kit."
  7. If you are an off shore blue water sailor or an off road, all terrain boondocker, you should consider using the integrated
    "urine tank."
