According to a survey carried out by the Finnish Consumer Agency, composting dry toilets have a price range of EUR 200 to EUR 1,700. In addition to the volume, the price also depends on a number of other features.
A composting dry toilet helps to decrease waste water discharges in sparsely populated areas. It is particularly well-suited for holiday homes that are not equipped with sewers or electricity.
The Finnish Consumer Agency and Finland’s Regional State Administrative Agencies have compared the prices of composting dry toilets intended for holiday homes. The survey did not cover products using water or electricity or chemical toilets in which the waste is not composted.
The prices of 21 different composting dry toilets on sale at 71 retail outlets in different parts of Finland were compared and the information was collected in April. The products found at retail outlets accounted for only about one half of all models known to be available. Dry toilets are also supplied on order.
The price depends on many factors
There are big differences between the prices of composting dry toilets. The products included in the survey had a price range of EUR 195 to EUR 1,690. The price does not depend on any single factor but is influenced by such matters as the type, construction and volume of the toilet. The ease of use and maintenance and reliability in different circumstances may also push up the price.
For example, the Biolan Naturum dry toilet costs about EUR 1,500 but is suitable for indoor use, fits into a small space and separates different types of waste into separate containers. The Populett model of the same manufacturer has a volume of 300 litres and costs only half the price of Naturum but does not offer the same range of features.
When purchasing a composting toilet, you should pay attention to the following:
- Do you want to install the toilet indoors or outdoors and will it also be used in winter? Most composting dry toilets are installed in outbuildings and many of them are used as traditional outdoor toilets. However, there are also a large number of models that can be installed indoors.
- What is the typical/maximum number of persons using the toilet? Small dry toilets with a seat and a container are well-suited for occasional indoor use. Dry toilets with bigger volumes and more containers are suited for larger households and more frequent use.
- What kind of maintenance does the toilet require and how often should it be emptied? Depending on the number and volume of containers and the frequency of use, the emptying interval may vary between one week and several months. Large models with more than one container require less frequent emptying.
- What is the size of the toilet? Does the installation require modifications in the building? Is additional equipment needed? For many models, such features as the ventilation pipe must be purchased separately. A small number of models can also be equipped with an electric fan for better composting and ventilation. A heating cable is required for outdoor toilets used in winter.
