Summer is the perfect time for kids to enjoy outdoor activities, and nothing screams “fun in the sun” quite like a backyard pool. However, store-bought kiddie pools can be small, flimsy, or expensive. That’s where a DIY kids’ pool comes in — a customizable, creative, and often more durable option that you can tailor to your space, budget, and your children’s preferences.
In this comprehensive guide, we’ll walk you through everything you need to know about building a simple, safe, and enjoyable homemade pool for your kids. From planning and materials to step-by-step construction and maintenance tips, this is your go-to resource for creating a backyard oasis without breaking the bank.
Why Build a DIY Pool for Kids?
Affordability
Traditional kiddie pools can range from $30 to $100 or more, and in-ground plastic pools often cost even more. A DIY pool allows you to significantly reduce costs by using affordable or recycled materials. You can also avoid costly installation fees and still end up with a sturdy and long-lasting solution.
Customization
One of the biggest advantages of a homemade pool is the ability to personalize it. You can choose the size, shape, and depth based on your children’s age and your backyard layout. Want a small splash zone for toddlers and a deeper area for older kids? With a DIY pool, that’s entirely possible.
Learning Opportunity
A DIY pool project can be an excellent bonding experience and teaching moment. Involve your kids in measuring, decorating, or even the construction process — it’s a hands-on way to teach them about planning, teamwork, and sustainable DIY ideas.
Eco-Friendly Option
Using repurposed materials like tubs, troughs, or wooden crates can help reduce your environmental footprint. Additionally, smaller DIY pools use less water, which can be a plus for water-conscious families and communities.
Planning Your DIY Kids’ Pool Project
Assessing Space and Safety
Before you begin, survey your backyard for the best location. It should be:
- Flat and level ground to ensure even water distribution
- Shaded to reduce sun exposure and overheating
- Accessible to a water source and electricity (if needed)
- 远离尖锐物体或粗糙地面
Safety is paramount. Ensure that the pool is away from roads, decks without railings, or any potential hazards. If you have a fence or plan to install one, do so to create a secure play area.
Determining Size and Depth
For toddlers (ages 1–3): A shallow depth of 6–12 inches is safest and enough for splash play.
For older kids (ages 4+): Depth of 18–24 inches allows for more active play and even small floats.
Measure how many kids will typically use the pool at once and plan the size accordingly. A diameter of 3–5 feet works for a small circle pool, while rectangular designs can be as large as 6×8 feet.
Choosing the Right Material
Common materials for DIY kiddie pools include:
- Plastic storage bins or kiddie pools
- Wooden frames with liners
- Metal horse troughs or stock tanks
- Inflatable pool modifications
- Kids’ bathtubs or washbasins
Each comes with its pros and cons in terms of cost, permanency, portability, and aesthetics. We’ll explore these in more detail below.
Step-by-Step Guide to Building a DIY Pool for Kids
Option 1: Build a Wooden Pool with Liner
Materials:

- Protective gloves and sandpaper
Step 1: Choose Your Tank
Standard sizes range from 4ft x 2ft to 6ft x 2.5ft or more. Ensure it’s food-grade and has no harmful residues.
Step 2: Prepare the Ground
Level the ground and create a smooth base using sand or old pool covers.
Step 3: Paint or Decorate
Using non-toxic, water-resistant paint or a vinyl decal wrap, customize the tank for a fun kids’ look.
Step 4: Drill Drain Hole (Optional)
For easier emptying, install a garden hose faucet using rubber or plastic bushings to prevent leaks.
Step 5: Fill and Use
Hose water directly into the tank until full — and let the fun begin.
Option 3: Repurpose a Plastic Container
Old storage bins, large tubs, or even large kiddie pools can be upgraded for a more permanent setup.
Steps:
- Clean and sanitize the container.
- Secure it to a level base using bricks, pavers, or anchoring.
- Add a simple filtration system or solar cover for temperature control.
- Decorate the outside with paint, stickers, or waterproof wraps.
Adding Fun and Safety Features
Water Temperature Control
To keep the water cool, use a solar cover or a simple shade sail. For chilly areas, add a small solar heater designed for kiddie pools.
Drainage and Water Removal
If you want to drain your pool quickly, install a simple valve or spigot at the bottom. Alternatively, use a pool pump or siphon hose for easy water removal.
Kids’ Play Accessories
Enhance the fun with foam noodles, floating animals, or splash rings. You can also set up a small water table nearby with cups and toys for toddlers.
Optional Shade and Protection
Set up a temporary canopy, umbrella, or shade tent over the pool to protect against sunburn. UV-protective clothing and hats for the kids can be a smart addition too.
Surface Protection
If the pool sits on grass or concrete, add a soft rubber or foam base to cushion falls and protect tender feet.
Maintenance and Storage Tips
Daily & Weekly Cleaning Tips
After each use, remove debris and rinse the pool. Once a week, drain water completely and scrub it down with a mild bleach solution (1 part bleach to 10 parts water) to kill bacteria and algae.
Winter or Off-Season Storage
If you live in a cold climate, drain and thoroughly clean the pool before storing it indoors. For in-ground or semi-permanent setups, consider covering with a tarp or insulating it.
Inspect for Wear and Tear
Regularly check for cracks, leaks, or fading color. Steel tanks can rust over time if not properly maintained. Use rust-resistant paint or a coating like Krylon or epoxy spray if necessary.
Water Quality Management
Use chlorine tablets or non-chlorinated treatments to keep the water clean. UV light sanitizers are also effective and environmentally friendly.
Budget-Friendly Inspiration and Creative Modifications
Portable Pool Bases
If you live in an apartment or have limited space, place your DIY pool on a strong, cleanable mat or inside a balcony planter box.
Mini Pools for Different Ages
Create multiple zones: a small, shallow splash pool for toddlers and a deeper area next to it for kids who can swim or dive.
Themed Pools
Transform your pool into a jungle zone, pirate ship, or beach scene with decals, vinyl letters, and themed toys for added fun.
DIY Obstacle Courses
Add floating steps, noodles, or mini inflatables to create a water obstacle course the kids can play and race through.
Recycled Material Usage
Use old bathtubs, large food-grade barrels, or truck bed liners to create one-of-a-kind pool designs while reducing waste.

What materials are needed to build a DIY kids’ pool?
To build a simple DIY pool for kids, you’ll typically need a few basic materials including a durable plastic or rubber pool liner, wooden or concrete blocks for the frame, and a level surface. Depending on the design, you might also require screws, brackets, and a tarp or landscape fabric to protect the liner. For above-ground or semi-in-ground builds, lumber like pressure-treated wood or composite decking can provide a sturdy frame, while a solid base like sand or gravel can help with drainage and leveling. It’s also advisable to keep tools like a drill, measuring tape, shovel, and saw on hand.
For added safety and comfort, consider using non-slip pool coping or edging materials around the rim of the pool. You’ll also need a way to fill and drain the pool, so a garden hose and possibly a submersible pump are practical additions. If you’re aiming for a more permanent structure, you might consider adding filtration systems or PVC piping for water circulation. Always choose materials that are safe for children, resistant to mold and rot, and capable of withstanding prolonged exposure to water and sunlight.
How much does it cost to build a homemade pool for kids?
The cost of building a DIY kids’ pool can vary depending on the size, materials, and design. On average, a basic above-ground pool using wood and a plastic liner can cost anywhere from $100 to $500. If you already have some of the necessary tools or materials, the overall expense can be significantly lower. Liners are among the largest costs, with durable ones ranging from $50 to $200 depending on the size and thickness. Wooden frames, especially if using pressure-treated lumber, can also contribute to variable costs based on your design and local lumber prices.
If you’re incorporating additional features like a filtration system, lighting, or decking, the costs can increase. However, these upgrades can also add long-term value and usability. By comparison, a store-bought inflatable or plastic kiddie pool with similar capacity may cost just as much but with less durability. Building your own offers customization and potentially a more robust and longer-lasting solution. Shopping at local hardware or discount stores, or reusing materials from old projects, can help keep costs low.
How long does it take to build a DIY pool for kids?
Building a DIY kids’ pool can typically take anywhere from one to three days, depending on the complexity of the design and the materials used. A simple above-ground wooden frame pool with a pre-made liner might take just a few hours to complete, especially if the ground is already level and prepared. The process includes assembling the frame, securing it in place, laying down the liner, and filling it with water. If you’re incorporating more advanced elements like filtration or a custom base, additional planning and installation time will be needed.
Weather conditions and the number of people helping can also influence the timeline. Weekend projects with two people are often manageable and efficient. It’s important to allow time for materials to settle and for the liner to conform properly once filled with water. If working with concrete or wood that requires sealing, drying time should also be factored in. Overall, with a clear plan and proper materials prepared ahead of time, constructing a backyard pool for kids can be a quick and rewarding project.
Is it safe to build a homemade pool for kids?
When built correctly, a homemade pool for kids can be just as safe as a store-bought one. The key is to focus on construction quality, materials, and supervision. Always ensure the structure is stable, the liner is properly secured, and the edges are smooth and free from splinters or sharp components. Using slip-resistant materials for the surrounding area and ensuring the base is secure helps reduce accidents. Additionally, avoiding deep designs and maintaining a relatively shallow depth keeps the pool appropriate for younger children.
However, safety should not end with construction. Even small backyard pools require active adult supervision when in use. Consider adding safety features such as a removable cover, pool fence, or alarm for added security. Regular maintenance like cleaning, checking water quality, and ensuring water is drained when not in use helps prevent bacterial growth or mosquito breeding. Ultimately, a well-constructed and thoughtfully maintained DIY pool can offer a safe, fun, and educational water play option for children.
What size should a DIY kids’ pool be?
The ideal size for a DIY kids’ pool typically depends on the age and number of children who will be using it. For toddlers and young children, a pool that is 4 to 6 feet in diameter and around 1 to 2 feet deep is usually sufficient. This allows them to splash and play safely without the risks associated with deeper water. If you have multiple children or plan for older kids to use it, you might consider a larger pool, up to 8 feet in diameter or more, to give everyone enough space to enjoy without overcrowding.
It’s important to balance the pool size with the available backyard space. You’ll also want to leave enough room around the pool for safe access and deck seating or lounging areas. Keep in mind that larger pools will use more water and take longer to fill and clean. If the pool is meant for occasional use, a smaller and more portable design might be preferable. For a permanent installation with added features like a filter, a slightly larger footprint may be worth the added usability and fun.
Can I make the DIY pool portable or permanent?
Yes, a DIY kids’ pool can be built as either a portable or permanent structure, depending on your preferences and available space. A portable pool can be constructed using a removable frame, such as wood or PVC, and a durable liner that can be disassembled and stored when not in use. This option is ideal for small backyards or those who want to clear space after the summer season. Using lightweight materials and keeping the size manageable helps with portability and ease of setup each year.
On the other hand, a permanent installation involves securing a more durable frame, possibly using concrete or composite materials, and ensuring the pool is well-integrated into the landscape. A permanent DIY pool may also include a simple filtration system and a surrounding deck or patio for comfort and aesthetics. This version adds more value and convenience over time. Whether you choose portable or permanent, always ensure the structure is safe, well-drained, and built to withstand seasonal weather changes and regular use.
How do I maintain and clean a DIY kids’ pool?
Maintaining a DIY kids’ pool involves regular cleaning and proper water care to ensure it remains safe and enjoyable. Drain and refresh the water every few days, especially during hot weather and frequent use. Remove debris like leaves and insects regularly with a net or skimmer, and scrub the liner with a soft brush and mild detergent to prevent algae or bacteria buildup. If the pool is above ground, make sure the surrounding area is free of dirt and trash that may blow into the water.
To further extend its usability and cleanliness, consider using a pool cover when the pool is not in use and installing a small filtration system or pump for continuous water circulation. Water treatments like chlorine tablets or non-chemical alternatives can also help keep the water clean and safe, especially for longer use. Always dry the pool completely before storing it at the end of the season to prevent mold and extend the life of the liner. With proper care, your DIY kids’ pool can be a clean, fun, and long-lasting addition to your backyard.
