Making a concrete slab for an outdoor shower can be a profitable addition to the garden and outside landscape. An outdoor shower can be a great way to cool off on those hot summer days or to clean up from a day in the garden. It is a rewarding experience and will put money into your pocket by doing it yourself.
Things You'll Need
- 16 p nails
- 2 by 4’s
- Ready mix concrete
- Finish trowel
Dig the ground where you want the slab to be placed. The overall size is your choice, but the slab should be placed below ground level, where the top of the slab is approximately one inch higher than the surrounding grade level. Be sure to lay in at least three to four inches of gravel below the wood form. This will make the hole about seven to eight inches deep.
Form the concrete slab, by cutting the 2 by 4’s to the correct size, and nail the 2 by 4’s in place to form the square or rectangle of the slab form. Set the form in the ground on top of the gravel base, and backfill around the form with dirt to keep it in place while you are pouring the concrete.
Mix the ready mix concrete in the wheelbarrow using the hoe to mix the concrete. Follow the instructions on the bag for adding the correct amount of water and consistency of the concrete. Fill the form with the concrete using the shovel and fill the corners of the wood form first and work your way into the center.
Use the finishing trowel to give the slab a slick finish. The smoother the finish, the more water-resistant the slab will be. Since this is an outdoor shower, the water can simply run off onto the lawn.
Remove the forms after the concrete has thoroughly cured; generally, it takes two days for a full cure. Backfill around the new slab with gravel. You should have at least twelve inches around the slab for the water run off. This will allow the water to drain away from the slab.
