The making of a Master

The Dometic MasterFlush is a clean, odor-free toilet with a powerful flush. The stainless steel macerator blades ensure an easy and thorough discharge of the holding tank as waste is macerated into a fluid slurry. It also allows the tank to be located anywhere you please. The MasterFlush's two low-flush options ensure water supplies last longer while also flushing the bowl clean. The compact design, featuring an angled back, saves space in the head while also facilitating user comfort. Finally, its ceramic bowl is both easy to clean and adds a premium finish to the toilet.

The reason you need a macerator toilet

Macerator flushing technology has many advantages. Firstly, it allows the toilet and waste holding tank to be positioned apart from each other. This offers flexibility in terms of installation and also means that smells are more easily isolated away from the vehicle's living space. The macerator's stainless steel blades also ensure that holding tank effluent is more fluid and avoids the “mounding” of waste. This makes discharge from the tank easier and more thorough. And there is no need to worry about potential blockages caused by wads of toilet paper. A macerator toilet removes risks and simplifies waste disposal – making it a quick job!
