Simple Outhouse Plans

This step by step diy woodworking project is about a simple outhouse plans. This outhouse is super easy to build, so you should not worry about if you don’t have much DIY experience. Make sure you read the local regulation so you can comply with them. This outhouse is built from wood, therefore I recommend you to invest in weather resistant. Take a look over the rest of our woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building a simple outhouse

Building-the-floor-frame

The first step of the project is to build the base for the outhouse. Cut the components at the right dimensions and then lock them together with 6″ screws. Make sure the corners are square and align the edges flush.

Floor slats

Continue the project by fitting the 2×4 boards to the base frame. Drill pilot holes and insert 2 1/2″ screws to lock the slats into place tightly.

Front-wall-frame

Next, you need to continue the project by assembling the front wall for the outhouse from 2×2 lumber. Cut the components at the right dimensions and then drill pilot holes through the plates. Insert 3 1/2″ screws to assemble everything together tightly. Make sure the corners are square.

Back-wall-frame

Build the back wall frame for the outhouse, using the same techniques described above and the information from the diagram.

Front and back walls

Fit the back and front wall frames to the base of the outhouse. Plumb the frames with a spirit level and then drill pilot holes through the bottom plates. Insert 3 1/2″ screws to lock the walls into place tightly.

Side wall supports

Fit 2×2 supports to the sides of the outhouse. Drill pocket holes at both ends of the supports and then insert 2 1/2″ screws to lock them into place tightly. Check if the corners are right angled for a professional result.

Fitting-the-rafters

Fit the 2×2 rafters to the top of the outhouse. Align the rafters with attention, drill pilot holes and insert 2 1/2″ screws to lock them into place tightly.

Side slats

Fit 1×6 slats to the sides of the outhouse. Align the edges with attention and leave no gaps between the slats. Insert 2″ nails to lock the slats into place tightly. You can also use plywood, OSB or tongue and groove boards.

Back wall slats

Fit the slats to the back of the outhouse, as well.

Fitting the roof slats

Fit 1×4 support boards to the top of the rafters, as well. Center the boards into place so you can create even overhangs on both sides. Use 2″ to lock the boards into place tightly.

Fitting the trims

Fit 1×2 trims to the sides of the roof and 1×3 trims to the front and back. Use 2″ nails to lock the trims into place tightly.

Fitting the roof sheets

Fit the roofing sheet to the top of the roof. You can use plastic or metal roof sheets for the project. Alternatively, you can use 3/4″ plywood instead of the boards, so you can install asphalt shingles.

This outhouse is super easy to build and it is also very sturdy.

Fill the holes with wood putty and let them dry out for a few hours. Smooth the surface with 100-220 grit sandpaper and remove the residues with a damp cloth.

Top Tip: Apply a few coats of paint or stain to the components, to enhance the look of the project. Design is a very subjective area, so you can make modifications to the project so it suit your needs. Check out the rest of the project, to learn how to build the seat and the front door.
