Spas are special features in the home landscape that deserve special treatment. Flowering shrubs, screened enclosures, arbors, trellises and statuary are a few of the ornamental choices to decorate. Whether your spa plans are simple or elaborate, your options include live plants and wooden structures. It's not difficult to build a spa enclosure as a weekend do-it-yourself project.

Things you need
- 4 pieces of 10-feet-by-4-by-4-inch pressure-treated timber
- 4 pieces of 10-feet-by 2-by-6-inch pressure-treated support boards
- 4 pieces of 4 feet-by-1-by-1-inch timber
- 4 pieces of 3 feet-by-1-by-1-inch timber
- 3 pieces of 3-by-9-feet trellis
- 4 pieces of 3-by-8-feet trellis
- Tape measure
- Large clamps
- Galvanised screws and power drill
- Posthole digger
- 4 large utility buckets with handles removed
- Pea gravel
- Weather-seal deck paint and brushes
Paint all the wood and lattice pieces with weather-seal deck paint, before you assemble the wood structure, and let them dry thoroughly.
Measure 8-by-8-feet around the spa and mark four corners.
Dig 2 feet deep postholes (or holes as deep as the utility buckets) at all four corners, large enough in diameter to fit the utility buckets. Put a utility bucket into each hole and put a 1/2 inch of pea gravel in the bottom of each bucket.
Place a post in each bucket and fill the buckets with cement around the posts, ensuring they are straight and level.
Brace each post by screwing a 1-by-1-inch-by 4-feet length of wood horizontally across the front and back three feet from the ground for cross-bracing. Place a 1--by-1-inch-by 3-feet length of wood so that one end sits under each cross-brace and the other end touches the ground, bracing the post in a level position to dry. Let the cement cure for one day.
Screw two support boards to the outside of parallel posts 6 inches from the top of the posts and two support boards to the inside of the same posts, also 6 inches from the top. If you are working alone, use the clamps to hold them in place while you are drilling. These are the supports upon which the three 9-feet pieces of trellis will rest.
Place the three 9-feet pieces of lattice on top of the support boards, above the spa, and screw them in place.
Place an 8-feet piece of lattice on the outside of each corner post and screw them into place to complete the spa enclosure.
Tips and warnings
- Attach hooks to the ends of the support boards for hanging plants.
- Make a larger enclosure for a larger spa with posts spaced farther apart and longer support boards.
- Use rounded posts and sapling trees for support beams for a rustic enclosure.
- Plant climbing plants like roses, honeysuckle, clematis, or grapes at the posts to grow up and over the top of the enclosure for a green, growing roof. You can plant gourds, pole beans, zucchini, and cucumbers to cover the trellises.
