Steps
Drain and Clean the Pool
Pump out all water and scrub the surfaces. Check local regulations — some areas require permits to drain pool water. Never drain directly into storm drains.
Estimated time: 2 days
Punch Drainage Holes
Drill or jackhammer several 2-inch holes through the pool floor to allow water drainage into the soil below. Without drainage, the pool will collect rainwater and become a swamp.
Estimated time: 2 days
Partial Fill with Rubble and Gravel
Fill the deep end 50-75% with clean rubble, broken concrete, or gravel. This reduces the amount of topsoil needed and creates a drainage layer. Do NOT use organic fill that will decompose and settle.
Estimated time: 5 days
Add Landscape Fabric and Topsoil
Layer landscape fabric over the rubble to prevent soil from washing into the drainage layer. Fill the remaining depth with quality topsoil mixed with compost.
Estimated time: 4 days
Build Raised Beds or Design Garden Layout
Build raised bed frames from cedar or galvanized steel on top of the fill. Design pathways, a small patio area, or a tiered garden taking advantage of the shallow and deep end levels.
Estimated time: 5 days
Plant and Irrigate
Install drip irrigation connected to a timer. Plant vegetables, herbs, flowers, or ornamentals. The sunken design provides natural wind protection and heat retention for extended growing seasons.
Estimated time: 3 days
