A sod cutter, rented from a hardware store, can help you clear large areas of grass with ease. Applying a grass and weed killer here is also useful. Removing all the plants now ensures that they won’t grow back later and damage the pool.

To ensure that the rails are spaced properly, use a tape measure to gauge the diameter of the circle. The rails should be the same distance apart on all sides.

Use the level to ensure each plate is level and even with each other. Typically you will need to slide the rails into the grooves on the plates. Otherwise, leave the rails on top of the plates. Patio stones or blocks may be used in place of pavers.

Use a shovel or rake to move the sand around inside the circle. You want the sand to be distributed as evenly as possible under the pool’s bottom.

Check the sand’s consistency by walking on it. If you leave footprints, water and tamp it down again.

Instead of using a level, you can use string. Place stakes around the area’s border and connect them with strings lowered onto the soil. The spots that don’t reach the string are lower than the ones that do.

More sand is needed to to level out lower areas, so dump more of the sand there.

For instance, if your pool is 15 ft (4. 6 m) wide, connect 2 8 ft (2. 4 m) boards.

Your shoes will leave divots in the sand. These will fill in as you rotate the board. When you’re done rotating it, step out of the circle and shovel sand into the remaining divots.

The sand may need to be soaked and tamped down multiple times to be completely hardened.
