Evaluate the function.
Is your outdoor shower for bathing sandy kids or for full-fledged relaxation? If all you want is a quick rinse, you can get away with the barest of plumbing, but if you want to bring the conveniences of the indoors out, you’ll have a bigger project on your hands. Consider upgrading your hot-water system if guests linger under the spray. And get serious about privacy: If you’re planning romantic showers under the stars, build a door.

Design the drain.
When you build over sandy soil, you may need only an opening in the pressure-treated flooring, but soils that drain slowly will require more elaborate systems, such as a French drain, which directs water underground into drain fields or dry wells. Soap and shampoo residue can clog drainage systems, in addition to threatening the natural vegetation, so use eco-friendly products.

Remember the plumbing.
If you’re constructing a new home, run plumbing in the wall that the outdoor shower shares with the house. But if you have to retrofit a shower, consider hiding exposed pipes behind a wall built for this purpose.
