17 Simple Outhouse Plans You Can DIY Cheaply
Simple outhouse plans help you DIY a wooden structure to accommodate your choice of a toilet, be that a pit, flush, or composting toilet. Free online DIY outhouse plans and ideas outline the materials, tools, and techniques you’ll need to build a hygienic, compliant, and durable outhouse. Cheaply!
Essentially, an outhouse has two main parts:
- The waste disposal system (toilet type).
- The sheltering structure (the outhouse).
The type of toilet you will use in the structure will play a significant role in the planning and design of your DIY outhouse structure.
- If you plan to build a traditional outhouse with a pit latrine (a hole in the ground), you will need a light wooden structure that can move without fuss when the outhouse hole fills up.
- A flushing toilet in an outhouse will need a septic tank. But the structure will typically be permanent and can therefore be as elaborate as you desire.
- A composting toilet is portable, dry, and self-contained. The structure, therefore, can get elevated (a tree outhouse, anyone?), freestanding, or set in a foundation.
- There is a fourth option! A composting outhouse, where the solid waste gets composted in bins beneath the elevated permanent structure (on a slope or a deck).
There’s much more to cover regarding the best way to manage pee and poop on a homestead, which we’ll get into as this article unwinds.

To prevent poo from releasing pathogens into groundwater and the atmosphere, eco-wise homesteaders are building composting outhouses like this one at Dirtpatcheaven.

Urine is diverted into a separate container and used to nourish compost heaps and garden greenery.

Simple Outhouse Plans – FAQs
Building a simple outhouse is much easier with the plans shared in our guide! We also know you may have questions after examining these outhouse ideas.
So – we compiled a list of answers to help! May they find you well.
An outhouse can be kept free of odors by keeping urine off the fecal matter using a urine diverter. Covering the fecal matter in lime, wood ash, sawdust, woodchips, or peat moss will eliminate smells from the feces.
Ventilating the outhouse and toilet with an extraction fan and pipe vent or chimney will also help eliminate bad smells. A 50:50 mix of water and vinegar used in a spray bottle kills bacteria that add to odor formation.
An outhouse hole should be at least four-feet deep and three feet by three-feet wide to comply with most state regulations. In some states and countries, outhouse pit latrine holes should be at a minimum of four-feet deep.
In most jurisdictions, outhouse holes can only get dug if they’re at least 70 feet from the nearest well or water source.
A simple outhouse can get built in as little as two days if the earth is easy to dig and the builders have all the skills, tools, and materials necessary to make the construction process as smooth as possible.
You can build an outhouse for under $20! The secret is to use repurposed timber, materials, and fittings.
Outhouse foundations can get built using heavy timber beams, stones, rocks, or concrete. A good outhouse foundation will be level, durable, strong, weather-resistant, and termite-proof.
Zero dollars! If you have a shovel – you can dig an outhouse hole for free. Hiring a contractor to dig the outhouse hole with an excavator or backhoe could cost around $300.
A legally compliant outhouse must have a vent to expel pathogens from the structure and eliminate odors that attract insects and critters that could transmit harmful bacteria to humans and animals in the area.
The origins of the crescent moon cutout on an outhouse door are uncertain. Some say the moon represents mythological feminine order, while others claim the design is purely functional as a door handle and air vent.
The best wood for an outhouse will be weatherproof and termite-resistant. Cedar is the most popular wood used for custom outhouses, while treated timber and pallet wood are excellent for DIY project outhouses.
It is always safer to consult with your local building code authority before erecting an outbuilding on your property. In many states, a rural outhouse without a concrete foundation can get erected without planning permission.
Traditional outhouses often have two holes to extend the period the outhouse can remain in one location. When one outhouse hole fills, the other empty hole gets opened for use. Sometimes, one outhouse hole is used for urine, while the other gets used for feces. Composting outhouses sometimes use a two-bin method to allow one toilet to be in use while the other bin composts in situ.
Human feces exposed to oxygen, carbon, nitrogen, heat, and time provide a natural feeding and breeding ground for microbes that break down the solid waste into a soil-like substance that can get used as composting material.
Putting the Lid Down
With these 17 plans to assist, you can make an informed choice and begin your DIY outhouse project.
For our money, a composting toilet is the best way to go – no digging, no splashing, no holes in the outhouse floor, no flies, and no smells if you ventilate well and cover the poo with sawdust or wood ash.
Get a Kreg pocket hole jig to execute professional screw joints in the timber frames and to make a cheap urine diverter using an automotive funnel feeding into a one-gallon jug strapped to a five-gallon bucket. House this outhouse contraption in a wooden box with a toilet seat, and you’re sitting pretty!
Whichever DIY outhouse plan you choose, make that throne your own!
