Small Pools, Big Savings: 22 Affordable Backyard Ideas
Not all pools need Olympic sizes or five-figure budgets. These 22 ideas show how small pools can fit your yard and wallet.
From simple DIY projects to smart pre-made options, you’ll find choices for every skill level and style. Each idea comes with cost estimates and best-use tips to help you pick the perfect small pool for your needs.
1. Stock Tank Pools
Metal or plastic stock tanks made for farm animals make perfect small pools. They come in round or oval shapes from four to eight feet across. Add a pump filter system to keep water clean. The metal ones heat up fast in the sun and look great with wooden decks built around them. Their firm walls stand up well to use year after year.
- Estimated Cost: $200–$600
- Weather Resistance: High with proper sealing
2. Inflatable Pools with Wooden Decking
Step up your inflatable pool game with a simple wooden deck built around it. This hides the plastic sides and makes the pool feel like part of your yard design. The deck helps keep grass and dirt out of the water. When summer ends, deflate the pool, store it, and use the deck space for other things until next year.
- Estimated Cost: $100–$800
- Weather Resistance: Seasonal use
3. Repurposed Shipping Container Pools
Old shipping containers make strong, ready-made pool shells. Cut to your wanted length, sealed, and fitted with proper plumbing, these metal boxes last for years. Their straight lines fit well in modern yards. Some people paint them, while others keep the raw metal look. You can set them above ground or sink them for a built-in feel.
- Estimated Cost: $3,000–$8,000
- Weather Resistance: Excellent
4. Above-Ground Pools with Landscaping
Store-bought above-ground pools look much better with smart landscaping. Plant tall grasses, small bushes, or flowers around the base to hide plain walls. Add a partial wood deck at one end for easy entry and a spot to sit. Stones or mulch paths leading to the pool help it blend with your yard’s overall look.
- Estimated Cost: $1,000–$4,000
- Weather Resistance: High
Enhance your above-ground pool’s appeal with these creative and budget-friendly deck ideas.
5. DIY Concrete Plunge Pools
Small concrete pools work well for cooling off fast. A simple square or round shape from 6 to 10 feet across makes a perfect plunge spot. Though they take more work to build than other options, concrete pools last for decades with proper care. Keep the depth around 4 feet to save on concrete costs while still having enough water to dip fully.
- Estimated Cost: $2,500–$5,000
- Weather Resistance: Excellent
6. Pre-Made Fiberglass Shell Pools
Small fiberglass shells cost less than big in-ground pools but offer the same smooth finish. They come ready to install in many shapes with built-in steps and seats. The slick surface fights algae growth and needs less scrubbing. Many companies now make small “cocktail pool” sizes just for tight spaces and modest budgets.
- Estimated Cost: $5,000–$10,000
- Weather Resistance: Excellent
7. Kiddie Pools with Stylish Surroundings
Even the humblest plastic kiddie pool looks better with thoughtful design around it. Place it on a level sand base or patio tiles. Add potted plants, outdoor rugs, and low tables nearby to create a fun water spot. This super budget choice works well for young families who want water play without big costs.
- Estimated Cost: $20–$100
- Weather Resistance: Low
8. Sunken Tubs Turned Cold Plunge Pools
Old bathtubs, especially deep claw-foot styles, make perfect small cold plunge pools when set in the ground. These tiny pools help with muscle recovery and boost health. Keep them cool with shade or ice. The smooth sides feel nice and clean easily. Some people add simple pump systems for water flow.
- Estimated Cost: $500–$2,000
- Weather Resistance: Medium
9. DIY Natural Swimming Ponds
Mini natural swimming ponds use plants instead of chemicals to clean the water. Create a small swimming zone with a plant zone next to it. The plants filter water while adding beauty to your yard. These pools take more planning but use fewer harsh products while making a home for helpful bugs and small wildlife.
- Estimated Cost: $1,500–$5,000
- Weather Resistance: Seasonal
10. Pallet Pool Decks Around Inflatables
Free or cheap wooden pallets make budget-friendly decks around basic inflatable pools. Sand the wood smooth, seal it against water, and arrange pallets around your pool. The wood warms in the sun, feels nice on bare feet, and gives the pool a more finished look. Add hinges to some sections for storage spots to hide pool gear.
- Estimated Cost: $300–$700
- Weather Resistance: Medium
11. Half-Buried Pools
Setting an above-ground pool halfway into the ground gives you the best of both worlds. It costs less than fully in-ground pools but looks more built-in than fully above-ground models. The half-height walls need less landscaping to hide them. This method also makes getting in and out easier for kids and older swimmers.
- Estimated Cost: $2,000–$4,000
- Weather Resistance: High
12. DIY Tiled Mini Pools
Small pools lined with bright tiles bring a touch of Spain or Morocco to your yard. Build a simple concrete shell, then add ceramic or glass tiles in blues, whites, or complex patterns. Though tiling takes time, the results last for years and catch the sun in stunning ways. Small tiled pools work great in sunny corner spots.
- Estimated Cost: $1,000–$3,000
- Weather Resistance: High
13. Upcycled Hot Tub Pools
Find an old hot tub for cheap or free, remove the jets and heater, and turn it into a small cool-water pool. The built-in seats work well for lounging. Many hot tubs have good shells that last years after the mechanical parts fail. Add a simple filter system and fresh coping around the edge for a nearly-new pool feel.
- Estimated Cost: $500–$1,500
- Weather Resistance: Medium
14. Compact Lap Pools
Narrow, long pools let you swim laps even in small yards. A pool just 3 feet wide, 4 feet deep, and 20 feet long gives enough room for good exercise. Some have current machines to let you swim in place, making them even smaller. These pools focus on function over lounging space but serve health goals well.
- Estimated Cost: $4,000–$10,000
- Weather Resistance: High
15. Tiny Pools with Water Features
Small pools feel special with added water features like fountain spouts or small waterfalls. The moving water adds sound, helps with cooling, and keeps bugs away. Even a simple wall spout that pours into the pool makes a basic design feel fancy. These features work well for pools meant mostly for sitting and cooling off.
- Estimated Cost: $2,000–$5,000
- Weather Resistance: High
16. DIY Pool with Sandbags and Tarpaulin
The simplest DIY pool uses sandbags to form walls with a heavy tarp liner. Fill the bags, arrange them in a circle or square, and drape the tarp over and down into the middle. Fill it with water, and you have an ultra-budget pool. This works best for one-season use or testing pool locations before building something more lasting.
- Estimated Cost: $100–$300
- Weather Resistance: Low
17. Portable Spa Pools
Soft-sided spa pools serve as great small swimming spots when used without heating. Most come with built-in benches and bubble systems that still work for cool water. These pools set up fast and pack away for storage. Their round shapes fit well in tight spots, and the insulated walls help keep water at nice temps.
- Estimated Cost: $400–$1,000
- Weather Resistance: Medium
18. Backyard Courtyard Pools
Turn a small patio or courtyard into a mini oasis with a pool that fills most of the space. In tiny urban yards, the pool becomes the main feature, with just enough decking around the edges for chairs. These pools make the most of limited square footage while still giving you full water fun without leaving home.
- Estimated Cost: $3,000–$6,000
- Weather Resistance: High
19. Modular Plunge Pools
Factory-built modular pools ship in sections that bolt together on site. These strong pools come in small, fixed sizes perfect for yards with tight access. Most have clean, simple lines that look great in modern settings. The parts fit through standard gates and doors, making them good for spots where cranes can’t reach.
- Estimated Cost: $3,500–$7,000
- Weather Resistance: Excellent
20. Raised Pools with Privacy Screens
Build small above-ground pools with tall privacy walls on one or more sides. These screens block views from neighbors while creating a cozy swim space. Add built-in benches along the screens for changing or sitting. The walls can hold planters, lights, or hooks for towels to make the small pool area work harder.
- Estimated Cost: $1,000–$3,000
- Weather Resistance: Medium
21. Trough-Style Pools for Long Spaces
Skinny, long pools fit well along property lines or in the narrow side yards many homes have. Just 3-4 feet wide but up to 20 feet long, these pools give enough room to cool off without taking much space from gardens or play areas. Their simple shape makes them easier to build and cover when not in use.
- Estimated Cost: $1,000–$2,500
- Weather Resistance: High
22. Converted Water Trough Pools
Large plastic livestock troughs from farm supply stores make great small pools. Round models span 6-8 feet across, while oval ones run longer. Their tough walls stand up to sun and weather. Most come in black, blue, or green, which heat well in the sun. Add simple pool filters meant for above-ground systems to keep water clear.
- Estimated Cost: $300–$900
- Weather Resistance: High
Common Mistakes to Avoid with Budget Pools
Building a small pool on a budget works best when you dodge these common issues. Many people rush their projects or skimp in the wrong places, leading to problems down the road. Review these points before starting your small pool project to save time, money, and stress.
- Skimping on water treatment – Even small pools need proper chemicals or salt systems to stay safe for swimming
- Forgetting about permits – Check local rules first; many places require permits even for tiny pools
- Placing pools too close to trees – Leaves and roots cause constant cleaning and possible damage
- Ignoring proper foundations – Shifting ground under pools leads to cracks and leaks
- Using wrong materials for DIY – Not all plastics, woods, or metals work safely with pool water and chemicals
- Underestimating water weight – Small pools still hold tons of water that need proper support
- Cutting corners on electrical work – All pool pumps and lights need proper GFCI protection and sometimes professional installation
- Making pools too shallow – Pools under 3 feet deep heat up too fast and limit usage

How to Keep Your Small Pool Cool & Clean in Summer
Small pools heat up fast in hot weather and can get dirty quickly with less water to dilute debris. A few simple steps help keep your small pool fresh and cool all summer long.
Adding shade is one of the most effective ways to keep water temperatures pleasant. You can use umbrellas, sail shades, or plant trees nearby to block direct sunlight.
For particularly hot days, adding ice cubes or frozen water bottles provides quick cooling relief. Many pool owners find that running their filter systems at night when air temperatures drop helps maintain cooler water.
Small pools require more frequent cleaning since dirt and debris are more noticeable in less water.
Follow these maintenance tips for best results:
- Skim surface for leaves and bugs daily
- Brush pool sides and bottom twice weekly to prevent algae growth
- Test water chemistry twice weekly, adjusting chemicals as needed
- Use a pool cover when not in use to keep out dirt and slow evaporation
- Change about 20% of the water weekly for very small pools
- Consider installing a small UV filtration system for extra cleaning power
- Clean the filter more often than you would for larger pools
- Vacuum the pool bottom at least once a week
- Keep pets out to reduce hair and dander in the water
These simple practices help maintain clear, clean water throughout the swimming season without requiring excessive time or money. With proper care, even the smallest pool can provide refreshing relief all summer long.
