Toilet Options for Tiny Houses


If you decide to go off-grid, you will have to search for a toilet for your tiny house. The good news is that there are lots of tiny house toilets to select from. And just like normal toilets, tiny toilets vary from one type and brand to another.  So, how to find good flushing toilets for small houses?

We’ve created a list of some of the best tiny toilet options to consider. Before buying a tiny house toilet of your choice, you should consider how comfortable it is, its size, price, ease of maintenance, and whether it meets your needs or not.

At the start, using a tiny toilet may be challenging, but when you get used to it as I have become, you’ll find that handling human waste is not a big deal. The toilets that we’re going to discuss will offer you with different options and you can select a toilet that you feel meets your needs and budget.

What to consider when choosing a tiny house toilet

  • Size – the size of the toilet you select is very vital because there is limited space. A compact and portable toilet is a good choice. A big toilet will take up much space and be challenging to install.
  • Ease of use – tiny toilets have no connections to the sewerage system where waste is disposed. This means you will have to do a lot of cleaning and maintenance. Getting a toilet that is easy to clean after use is important. You may incur a bit of a higher sewer line repair cost, but that’s a fair trade-off for usability.
  • Maintenance – be ready to spend time and money to maintain your portable toilet. The simpler the toilet is, the more you’ll have to look after it and ensure that it is in good shape.
  • Price – look for a toilet that is within your budget. Composting toilets are the best and are offered at a great price. Incinerating toilets are efficient, but very costly.
  • Industry standards – the toilet that you acquire should meet industry standards so that different people can have an ample time using it.
