Sand Base Needed
Before You Start
Tools And Materials You Need
Have everything on this list before you start. Most delays come from mid-build hardware store runs.
Long Level + String Line
Used to verify the ground is level across the full footprint before laying sand. A 6-foot or longer level is ideal.
Rubber Mallet
For seating bottom rails and adjusting uprights without damaging frame components. Do not use a metal hammer.
Cordless Drill
Most frame hardware uses a single screw size. One drill handles everything — check your manual for the correct bit size.
Masonry Sand — 1–2 Tons
Budget 1 ton for an 18' round, 2 tons for a 24' round. Use masonry or washed concrete sand — not play sand.
Garden Hose
Long enough to reach from your water source to the pool center. You will also use it to wet the sand base during installation.
Outdoor GFCI Outlet
Your pump needs a dedicated outdoor outlet. Do not use an extension cord long-term — a proper outlet is required for safety.
Steps 01–03
Site Prep And Sand Base
01
Choose Your Location
3 feet clearance on all sides. Away from overhead power lines (10 feet minimum). Good sun exposure. Away from tree roots and low-drainage areas. Call 811 before digging — check for buried utilities.
02
Mark, Clear And Level
Drive a center stake, mark your circumference plus 1 foot. Remove all sod, vegetation, rocks, and roots. Level within 1–2 inches across the full footprint — always remove high spots, never add fill dirt.
03
Lay And Tamp The Sand Base
Spread 2–3 inches of masonry sand evenly. Lightly wet with a garden hose, then tamp firm. Create a slight cove where sand meets the wall. Add foam cove before liner installation to protect against tears.
Caution
Never add fill dirt to low spots. Fill dirt compresses unevenly and creates a tilted pool. Always remove high spots instead.
Caution
Do not proceed if out of level by more than 2 inches. An unlevel pool creates massive uneven wall stress and will eventually fail.
Good to Know
Foam cove is highly recommended. Place it along the base of the wall before the liner goes in — it protects the liner at the most vulnerable seam.
Steps 04–07
Frame Assembly And Liner Installation
04
Lay Bottom Rails And Uprights
Connect bottom rails to form the circular footprint. Place one cinder block or paver under each upright position. Verify the diameter is consistent — measure across the center in multiple directions.
05
Roll Out The Wall
Unroll the wall inside the bottom rail track. This takes 2–3 people — wear gloves, the steel edge can be sharp. Orient skimmer and return cutouts toward your equipment pad side.
06
Attach Uprights And Top Rails
Slide each upright into position. Attach top rails between uprights. Verify the pool is round before fully tightening. Snug is enough — do not overtighten.
07
Drop The Liner
Warm the liner in sun for 30–60 minutes first — warm vinyl stretches more easily. Overlap: drape over wall, secure with top rails. Unibead: snap bead into receiver channel as you work around. Work out all wrinkles before adding water.
Warning
Never use sharp tools near the liner. Remove shoes before walking in the pool during installation.
Caution
Work out wrinkles before filling. Once you have 6 inches of water in the pool, the liner is set and wrinkles become permanent.
Good to Know
Liner drop needs 3 people. One from center, two guiding around the perimeter. It makes a significant difference in how cleanly the liner drops.
Steps 08–10
Fill, Equipment And Water Chemistry
08
Begin Filling
Place the hose at the center of the pool floor and fill slowly. Monitor the liner and smooth any wrinkles by hand before they set. Stay nearby during the first few inches of fill.
09
Install Skimmer And Connect Pump
When water reaches the skimmer cutout, install the skimmer and return fitting. Connect pump to skimmer and filter. Fill the pump strainer basket with water before first start — running a dry pump damages the seal.
10
Balance Your Water
Test immediately after filling. Balance in this order: Total Alkalinity → pH → Calcium Hardness → Chlorine → Cyanuric Acid. Retest after 24 hours before swimming.
Warning
Never run the pump without water. It damages the seal within minutes. Always prime before starting.
Caution
Do not cut the skimmer hole early. Wait until water reaches that level — cutting too early causes tearing.
Good to Know
Water chemistry targets: pH 7.4–7.6 · Free Chlorine 1–3 ppm · Total Alkalinity 80–120 ppm · Calcium Hardness 175–275 ppm · CYA 30–50 ppm
