    BioLet Composting Toilet 55 BIO55a

    The all new BioLet 55 is the world's first fully automatic composting toilet. In our quest to provide our customers with a toilet that is as convenient to use and operate as a regular flush toilet, a fully automatic mixing system has been added in addition to the quiet fan, compost covers and double heaters.

    The BioLet 55a is an excellent choice for that extra bit of luxury for any location where a conventional toilet is difficult or impractical to install. Designed with the smaller family in mind the BioLet 25a is the perfect option for those applications where the extra capacity of the BioLet 65e is not needed.

    Rated at 3 - 4 people seasonal use the BioLet 25a is an excellent choice for the cottage, basement, barn, pool house or any place where an easy-to-use and convenient composting toilet is wanted.

    Equipped with a compost cover which hides any content from view, fan, automatic mixer and double heaters the BioLet 25a is the most convenient composting toilet on the market today. As with all BioLet toilets, the BioLet 25a is easy to install and very easy to maintain.

    About BioLet

    In 1972, Sture Andersson founded the original company in Sweden. His vision was to manufacture the most convenient waterless composting toilets in order to give customers a real alternative to regular flush toilets. The first model was called MullToa meaning composting toilet in Swedish. The MullToa fast became a wide-spread toilet alternative in Scandinavia. His idea to offer the best designed waterless composting toilet spread around the globe and by the mid 1980s MullToa and BioLet - its international brand name - were being patented and sold in over 30 countries.

    As the global leader in waterless toilet systems, BioLet introduces new features like the automatic liquid sensor & indicator light for emptying to make using and maintaining the BioLet toilets more convenient than ever!

    BioLet Toilet Systems introduces another milestone in composting toilet history. Improved air re-circulation combined with two new high-efficiency heaters and an adjustable digital power setting makes BioLet the most advanced waterless toilet system in the world. We added a soft closing toilet seat, improved compost cover technology and a smoother look to make it the most appealing composting toilet on the market today.

    Good and fast service. I’m remodeling the floor. I can’t wait at the moment I will connect it. Thank you for the quick delivery!

    Damien Rivera
    Comfortable and Attractive

    We're a family of four and the toilet works great for us. It's easy to use, easy to clean, easier than cleaning my cats litter box. Overall worth the price.

    Jair Collins
    Functions perfectly for us on our camp.

    There was no smell, no mess, discrete, doesn’t emit odors and easy to clean. Small size, easy to install and no water needed.

    Composts nicely

    Comfortable and composts well. Took a while to fit in but we did it with little help.

    Great improvement to our motorhome

    I’m simply in love with the comfort and lightweight style of this toilet. The seal is tight and odor free.
