A professional in-ground pool installation in the US averages $50,000 to $90,000 in 2026, and even an above-ground vinyl kit pool from Lowe’s runs $3,000 to $8,000 before deck and electrical. DIY small pool ideas on a budget close the gap between a wading kiddie pool and a full backyard build. The cheapest options start under $400, and even mid-range projects come in under $5,000 when you do the labor yourself.
Stock Tank Pools: The Cheapest Real Pool
Galvanized steel stock tanks designed for livestock have become the most popular budget pool in the past five years. Tractor Supply Company sells the most common sizes at predictable prices.
- 6 ft round, 2 ft deep: 390 gallon capacity, $260 to $320.
- 8 ft round, 2 ft deep: 700 gallon capacity, $400 to $480.
- 10 ft round, 2 ft deep: 1,100 gallon capacity, $550 to $650.
- 2x4x2 ft oval: 169 gallon capacity, $130 to $170.
Add an Intex 1500 GPH cartridge filter pump at around $90, basic chlorine tablets and pH adjusters at $40 to $60, and you have a fully functional small pool for $400 to $750 total. Plan on weekly water testing and refilling roughly every 2 to 4 weeks as evaporation and splashout deplete the volume.
Intex and Bestway Inflatable Pools
Inflatable above-ground pools have improved dramatically since the early 2010s. The Intex Ultra XTR Frame and Bestway Power Steel models hold up for 3 to 5 seasons with proper care.
- Intex 10 ft x 30 in Easy Set: $80 to $120, ideal for kids.
- Intex 12 ft x 30 in Metal Frame: $150 to $200, family-friendly.
- Bestway Steel Pro Max 12 ft x 48 in: $300 to $400, deeper and sturdier.
- Intex Ultra XTR Frame 16 ft x 48 in: $500 to $700, ladder and sand filter included.
Site prep matters. Level the ground to within 1 inch of plumb over the entire footprint, and lay a Gorilla Floor Pad underneath to prevent punctures. A sloped install puts catastrophic pressure on the wall and fails within weeks.
Container Pools and Repurposed IBC Tanks
Shipping container pools have exploded in popularity, both as DIY projects and as turnkey products. A used 20 foot container costs $2,500 to $4,500 in most US markets. Lining it requires either a custom vinyl pool liner ($800 to $1,500) or paint-on rubber pool coatings ($300 to $600). Add a small pool pump and filter system at $400 to $700 and a budget container pool comes in around $4,000 to $7,000 total.
IBC totes (intermediate bulk containers) at 275 to 330 gallons each retail for $100 to $200 used. Two side-by-side make a 660 gallon plunge pool. Cut the tops off, line with food-grade pool liner material, and frame with deck boards for a polished look. Total cost: $400 to $800 plus labor.
Verify the previous contents of any used container or tote. Anything that held chemicals or pesticides is unsafe regardless of how thoroughly you clean it. Stick to former water, juice, or food storage units only.
Concrete Block Plunge Pools
The most ambitious DIY option uses concrete masonry units (CMU) to build a real in-ground or partially buried plunge pool. A 6×10 ft plunge pool requires roughly 200 CMU blocks at $2 to $3 each, 40 to 60 80 lb bags of mortar mix at $7 each, rebar reinforcement at $300, and a custom-fit vinyl liner at $400 to $800. Materials total $1,500 to $2,500 plus excavation.
The catch: excavation. A 6×10 ft pool 4 ft deep removes 9 cubic yards of soil. Hand digging takes 30 to 60 hours. A mini excavator rental at $250 to $400 a day makes it manageable for a weekend. Hauling the soil away costs another $200 to $500 unless you can use it on site.
Permits become unavoidable at this scale. Most jurisdictions require pool permits for anything over 24 inches deep, with engineered drawings, electrical inspection, and barrier compliance under IRC R326.
Permits and Codes You Cannot Ignore
Pool permitting catches every DIYer eventually. Three rules apply almost universally in the US.
Pools deeper than 24 inches require a barrier (fence, wall, or pool cover) at least 48 inches tall with self-closing self-latching gates. The IRC, IPC, and most state codes specifically reference this. Inflatable and stock tank pools meet the 24 inch threshold quickly when filled.
Electrical work for pool pumps requires GFCI protection within 20 feet of the pool, dedicated 20 amp circuits for most pumps, and proper grounding and bonding. NEC 680 covers the details. Plug-in pumps from Intex sidestep some of these requirements, but hardwired sand filter systems do not.
Setbacks from property lines run 5 to 10 feet in most jurisdictions, and overhead electrical service typically requires 22.5 feet of clearance from any pool surface.
Filtration on a Budget
A working filter is non-negotiable. Standing water without circulation grows algae and mosquito larvae within days. Three budget-friendly options work.
- Intex 1500 GPH cartridge filter pump: $90, fine for stock tanks and small inflatables. Replace cartridges every 2 weeks at $5 each.
- Intex Krystal Clear sand filter pump 2800 GPH: $250 to $300, handles up to 14,000 gallon capacity, sand changes every 5 years at $20.
- Hayward Power-Flo cartridge above-ground pump kit: $400 to $550, longer service life, fits any pool up to 24 feet.
Run the pump at least 6 hours per day during swim season, 8 to 10 hours in hot or humid climates above 85°F average.
Chemicals and Water Maintenance
Stock tank and budget pools need the same basic chemistry as a big pool. Test free chlorine (1 to 3 ppm), pH (7.2 to 7.6), and total alkalinity (80 to 120 ppm) twice a week minimum. A Taylor K-2006 test kit at $80 reads accurate enough for any residential pool. Cheaper strip-based kits work but read less precisely.
Stock chemicals at the start of every season: 5 lb of dichlor chlorine granules, 2 lb of pH down, 2 lb of pH up, 5 lb of alkalinity increaser. Total cost roughly $60 to $90 for a season of chemicals on small pools.
Decking and Surrounds That Look Good Cheap
A simple wood deck around a stock tank or above-ground pool transforms the look. A 4 by 12 ft cedar or pressure-treated deck with stair access runs $300 to $600 in materials. Skip composite decking at this scale, since the cost roughly triples.
For container and concrete-block pools, surround with pea gravel ($50 to $150 per pool) or simple stamped concrete pads ($300 to $600 DIY). A pergola or shade sail at $150 to $400 adds visual structure and sun protection without the cost of a permanent roof.
Build a real pool on your budget. Skip the temptation to overbuild beyond what you can maintain, and any of these diy small pool ideas on a budget will pay back in summer afternoons for years.
