Choosing a Toilet Seat

My toilets offer several different options with respect to toilet seats. One size does not fit all and since options are available with flushing toilets, why shouldn’t they be with a dry, composting system toilet? Let’s look at why someone would prefer one over the other.

The standard C-Head toilet seat is a modified, non-proprietary, “round” white toilet seat (per industry standards). It is designed to fit on a standard “round” porcelain toilet bowl. The C-Head comes with an upgraded model with heavy-duty hinges, since it will probably be exposed to more abuse than the standard at home toilet seat and it should last longer in a fixed use setting such as a cabin, tiny house, tree house or regular home for the same reason.


The C-Head uses what is somewhat erroneously called a “wood” or wooden” toilet seat. It is in fact made from a very high density material which consists of a plastic resin impregnated fine wood powder to create essentially a plastic seat with a wood powder filler/binder. That makes it highly water resistant. That being said, water droplets should not be allowed to remain on the seat if it is used to sit on when showering. Drying the seat is standard with any seat, plastic or wooden, simply to prevent the build-up of mildew on the toilet or in the bathroom. So the wooden toilet seats don’t take any more care than do the solid plastic toilet seats.

Solid plastic seats will not work on the C-Head toilet. This is because solid plastic seats are hollow on the underside and use increased camber to strengthen the plastic and save material and weight. This causes the seat to wrap down inside the bowl itself which can be done with a large mouth porcelain bowl but not with the flat surface and smaller opening on the C-Head housing lid. The C-Head purposely has a smaller opening because of design constraints and to help conceal the contents of the toilet from view.

The standard wood toilet seats we use come in five versions.


White round, White round with slow close feature (sometimes called soft close.Black roundWhite elongatedWhite elongated with slow close feature (special order)

Let’s look at each. First, round vs. elongated. The default white round seat has the advantage of using the least space which is a valuable consideration when being installed in boats, RVs and travel trailers. The seat extends over the front of the toilet cabinet (or housing as we call it) by two inches making the distance from the back of the toilet to the front lip of the seat 20 inches overall. This distance may effect the ability to open and close adjacent doors or allow more standing room in a small bathroom. It is also the least expensive alternative. The only real downside to the round seat is that it restricts visibility which can be helpful when learning to use the urine diverting aspect of the toilet.

The elongated seat can help to better see what you are doing to get everything to go where it is supposed to until you can establish a feel for the correct positioning. Even with the round seat, it usually doesn’t take more than a couple of uses to establish the correct location and position for sitting and it can be done without visualizing (flying blind so to speak), but that may take a few more tries. Larger people tend to have more difficulty visualizing what they are doing and may prefer the elongated seat. The elongated seats also have the advantage of giving the ladies more working space in the front, which can be desirable.

Slow close vs. regular close. It is always shocking when a toilet seat slams shut. The recent introduction of the “slow close” or “soft close” toilet seats has been a success for just that reason and not just the novelty of it. With the different types of applications that use the C-Head, it can be more than just eliminating a nuisance. It can be a safety feature. Two cases in particular come to mind. First, in any moving application, like boats or RVs it is easy to imagine that if the toilet is being used while underway, there is always the danger that an open seat or lid will be tipped by the movement and come slamming down if unattended. With the slow close feature, the seat will be softly lowered down, avoiding any injury or damage.

The second case where a slow close toilet seat lid would be advantageous is with a C-Head that is being used in a handicap user application. Here it is probable that the user may have limited strength or reflexes and the addition of a slow close feature eliminates the danger of the seat getting away from the user when closing the lid. This is a case where the owner would want to special order the elongated slow close toilet seat.

Black and White. With respect to color, white seats are easier to keep clean and don’t show scratches or fingerprints as easily as do black seats. Black seats may have some very minor scratches or burnish marks when they come from our factory but nothing that is visible from more than a few feet away. Black seats are beautiful and do enhance the appearance of C-Head toilets with a wood grain finish. That being said, it is a matter of preference.

People sometimes ask about whether we offer a “kids” seat. Actually, one of the great features of the C-Head is that, with the small opening, it has a built-in kids seat. Any child old enough to go to the bathroom by themselves can master the urine diverting feature of the toilet and doesn’t need to fear falling inside in the process. Children are naturally curious about “bathroom” stuff anyway so make it a game and tell them to be sure that everything goes where it should. In that regard, any of our seats should work for children.

Finally, it should be noted that all of the churnless versions of the C-Head come with no modification for the churning mechanism, specifically a hole in the top. They do come with the duo-lock seat-to-housing-lid snap down and the screws have been changed out with stainless
