Measure the depth of a 2-gallon bucket with a tape measure.
Clamp a piece of PVC pipe in a vise and cut off a section 1 inch longer than your measurement. The pipe's diameter should be large enough for the patio umbrella to slide into easily.
Stand the pipe in the middle of the bucket, and secure it in place with hot glue. Use enough glue to ensure a complete seal around the base of the pipe.
Brush a coat of petroleum jelly onto the inside of the bucket to make removal easier.
Mix enough cement and water to fill the bucket. Follow the mixing ratio provided on the cement package.
Tap the sides of the bucket with a mallet to free any trapped air bubbles.
Let the cement cure for 24 hours.
Cut the bucket off the cement with a utility knife, leaving the pipe in place. Wipe off the excess petroleum jelly with paper towels.
Decorate the stand as desired. You can paint it, glue decorative stones on it or simply leave it plain.
