How to Build an Outhouse That Doesn’t Smell?

  • Choose an appropriate site for your outhouse. Look for a spot that’s at least 100 feet away from a water source. Make sure the spot is on level ground and protected from wind.
  • Dig a hole that’s at least three feet deep. Line the sides and bottom with gravel and use a level to ensure it’s flat.
  • Construct the outhouse frame. Use rot-resistant wood, such as cedar or pressure-treated lumber. Make sure the floor is raised and the walls are securely attached to the frame.
  • Add ventilation. Cut two 4-inch holes near the top of the outhouse and fit them with vent pipes. This will help reduce odors.
  • Install a door. Make sure it fits securely in the frame and keeps out wind and rain.
  • Add a toilet seat and a bucket or a composting toilet. Composting toilets are much less smelly and require less frequent cleaning.
  • Cover the hole with a lid. Use a large, heavy rock or a thick board to seal the entrance.

How to Build an Outhouse That Doesn’t Smell

Building an outhouse is a great way to add a sense of privacy to your outdoor space and to provide a convenient place for your guests to do their business. But if not done correctly, it can also lead to an unpleasant smell. Fortunately, there are a few steps you can take to ensure that your outhouse doesn’t smell.


One of the most important steps to take when building an outhouse is to ensure that it is well-ventilated. Adding a vent to the roof of your outhouse will help to draw air out and reduce odors. You should also make sure that the door of your outhouse is fitted with a good seal to prevent any smells from escaping.

Proper Positioning

The positioning of your outhouse is also important when trying to prevent odors. Make sure to place it away from any sources of heat, such as barbecues or fire pits, as this can cause smells to linger. You should also make sure that the outhouse is positioned away from any windows or doors to your home, as this can cause unpleasant smells to enter your home.

Clean Regularly

It’s also important to clean your outhouse regularly to prevent any build-up of odors. Make sure to use a disinfectant to clean the interior and exterior of your outhouse, and to empty the waste regularly. You should also use a deodorizer to help reduce any lingering smells.

Choose the Right Materials

Finally, it’s important to choose the right materials when building your outhouse. Using materials such as wood or metal can help to reduce odors, as they are less porous and therefore less likely to absorb smells.

By following these steps, you can ensure that your outhouse is well-ventilated, positioned correctly, and made from the right materials to prevent unpleasant odors. With a bit of effort, you can make sure that your outhouse is a pleasant and convenient place to use.
