Cut six pieces of PVC pipe to 36 inches long. Place two pipes in a milk crate. Cut more PVC pipe of different sizes any length up to 34 inches long. Fill three milk crates and arrange the pipes in an interesting design.
Sand the top of each pipe with a band sander and loose sheet of 60-grit sandpaper to remove all burrs and uneven edges. Replace the pipe in the crate. Sand all of the pipe tops in all three crates. Push the three crates together. When you are finished all of the pipes will be glued together and form a single, long, rectangular base. Adjust any pipe placement for the best appearance. Your tall pipes will support a glass top so space them evenly and wide apart.
Pick up two adjacent pipes. Apply PVC glue along the edge where the pipes touch so that there is glue on both pipes. Press the pipes together at the glue while keeping the bottom of the pipes level. Add a band of painter's tape to hold the pipes in position while the glue dries.
Glue your pipes in pairs. After the glue dries, remove the tape and glue the pairs into fours. Tape as necessary. After the glue tries, remove the tape and glue into sets of eight. Tape as necessary. Continue until your entire base is glued together.
Spray paint your pipes to cover any lettering on the pipes. Allow the paint to dry for 24 hours.
Cut clear shower door spline to fit around the top edge of your top pipes. Press the U-channel spline tight to the plastic. Rest your glass top over the pipes.
