How to Create a Greenhouse From an Empty Pool

Remove the pool equipment and disconnect it from the power supply. Drain the pool of any water.

Measure the sides of the pool about 12 inches out from the edges. Cut sections of 2-by-4s to line up horizontally around the measured edges of the pool, meeting at the corners.

Drill holes every 12 inches through the boards and into the pool's concrete surface with a masonry bit. Blow out as much of the debris as possible from the hole with a hand held leaf blower.

Drive a concrete screw through the board into the concrete below. Set your drill on the slow speed setting and slowly sink the screw until the head is flush with the surface of the board. Repeat for all the drilled holes.

Place another layer of 2-by-4s on top of the anchored boards and screw them in every 24 inches with 2 1/2-inch wood screws. The top boards only screw into the bottom boards, not the concrete.

Drill 1-inch-wide holes, 2 inches deep, every 12 inches down the 2-by-4s on the long sides of the pool.

Measure the distance across the long sides of the pool from side to side. Multiply the result by pi (3.14) and divide it in half. This is the length of the 3/4-inch PVC pipes you'll stretch from side to side.

Using the measurement from Step 7, cut enough sections of the PVC pipes to fill the holes you drilled in Step 6, using a PVC cutting tool.

Set the ends of the PVC pipes into the 1-inch holes drilled in Step 6, forming an arch above the pool.

Drill two 1-inch holes, 2 inches deep, into the center of the frame on the short side of the pool where the door will go. Space each hole 24 inches apart and drill them straight down, not at an angle.

Slide two PVC T-fittings over the cross section of PVC pipe closest to the door end of the greenhouse. Slide them to the center, spaced 24 inches apart. Measure the distance from the T-fitting to the hole below. Cut a section of PVC to fit and slide into the hole in the board and then into the top T-fitting. This will serve as the outline for the door opening.

Cut four 6-inch sections of 1-inch PVC pipe. Slide two over the left side pipe in the door opening.

Stretch 12 mil plastic sheeting over the PVC pipes. Fasten the seams together with white plastic tape. Clamp the plastic in place to the door frame using PVC snap clamps.

Staple the edges of the plastic to the outside of the 2-by-4s framing the pool.

Make a PVC framed door by joining 4 sections of PVC to fit your doorway. Add the other two 1-inch-wide sections of 4-inch long PVC pipe to the left side of the door to act as the hinge, Glue them in place with PVC cement. Wrap the door in plastic and clamp the plastic in place with the PVC snap clamps.

Line up the door in the opening. Match the hinges and glue the left edge of each hinge on the door with the hinges on the frame. Hold it steady for 30 seconds until the hinge cements in place.
