Whether you want a pool for summer relaxation, family fun, or just a place to cool off, there are many DIY options that do not require professional installation. These DIY homemade pool ideas combine functionality with a touch of style, so your backyard feels more like a serene retreat than a construction site.
In this guide, we will walk you through 20 classy homemade swimming pool ideas that use simple techniques, cost-effective materials, and beginner-friendly instructions. Each one focuses on durability, aesthetics, and ease of use, so even if you’ve never built anything before, you’ll find a project you can confidently complete. These ideas are designed to blend with your garden or backyard layout while still giving you that clean, polished poolside look.
1. Stock Tank Pool With Deck Surround
Stock tanks are made of galvanized steel and were originally designed for watering livestock, but their durability and shape make them excellent for repurposing as swimming pools. We recommend using a large round stock tank because it’s sturdy, easy to clean, and holds water well even in the summer heat. Building a small wooden deck around it enhances the visual appeal while making entry and exit easier and safer. 
How to Make It:
- Place the stock tank on level ground.
- Use a power washer to clean the inside thoroughly.
- Attach a pool pump and filter using bulkhead fittings.
- Build a small circular or square wooden deck around it with pressure-treated lumber.
- Secure the deck with screws and seal with waterproof outdoor stain.
- Fill the tank with water and install a chlorine float or natural treatment system.
2. Wooden Pallet Pool Frame
We suggest using reclaimed wooden pallets to build a homemade pool because they are inexpensive and structurally strong when arranged vertically. When lined properly and reinforced, a pallet pool can support thousands of gallons of water while still maintaining an attractive rustic look. This idea suits large families or those who want a deep plunge pool.
How to Make It:
- Arrange 8 to 10 wooden pallets in a circle or square on level ground.
- Strap the pallets tightly together with ratchet tie-downs or metal brackets.
- Insert a waterproof heavy-duty pool liner into the frame.
- Fold the liner over the top edges and staple to the outer pallet wall.
- Add a foam pool underlay to soften the base if desired.
- Fill with water and install a small pump to maintain circulation.
3. Shipping Container Pool
We recommend using a recycled shipping container if you want a large, long-lasting pool with a sleek, modern design. Shipping containers are made of corrosion-resistant steel and can be adapted with insulation, plumbing, and decking for a high-end result. This is a bigger project but still achievable with basic tools and time.
How to Make It:
- Purchase a watertight 20 or 40-foot shipping container.
- Grind down rough interior spots and apply waterproof epoxy paint.
- Cut and reinforce one end if you want a window or shallow entry.
- Install a basic plumbing system with intake, pump, and outlet fittings.
- Line the interior with pool-safe vinyl or install fiberglass panels.
- Set on a leveled gravel base and fill with water.
4. In-Ground Tarp Pool
A tarp pool is one of the fastest DIY swimming pool options, using basic landscaping and waterproof tarp material. We recommend this if you’re on a tight budget and want a temporary but functional cooling spot during summer.
How to Make It:
- Dig a shallow hole (about 2 to 3 feet deep) in your desired pool area.
- Remove any sharp rocks or roots from the bottom.
- Lay down a thick tarp or pond liner over the hole.
- Secure the tarp edges with sandbags or large rocks.
- Add an inflatable ring or pool noodle rim for comfort.
- Fill with water and treat with chlorine tablets or natural solutions.
5. Above-Ground Frame With PVC Pipes
Using PVC pipe for the pool frame offers flexibility and durability without the weight of wood or steel. We suggest this idea for families who want a rectangular or oval-shaped pool that can be taken down and stored during the off-season.
How to Make It:
- Cut large-diameter PVC pipes to size for the pool’s perimeter and vertical supports.
- Use T-joints and elbows to connect into a sturdy frame.
- Wrap a waterproof liner tightly around the interior of the frame.

How to Make It:
- Dig a shallow basin in your backyard with a gentle slope.
- Lay a flexible pond liner across the entire surface.
- Place large rocks around the edge to hold the liner in place.
- Add flat stones inside for natural seating or steps.
- Use a pond pump for water circulation.
- Fill with clean water and treat with natural algaecide if needed.
8. Kiddie Pool Upgrade With Seating
Instead of using a kiddie pool as-is, we suggest upgrading it with a circular bench, canopy, and water filter. This transforms a basic plastic pool into a more functional and elegant water feature for children and adults alike.
How to Make It:
