Building a pool is one of the biggest home improvement projects you can take on. It is also one of the most rewarding — a well-planned pool adds living space, boosts your home’s value, and gives you a place to exercise, entertain, and unwind for years. But the planning stage is where most people either set themselves up for success or end up with expensive regrets.
This guide walks through every major decision, from pool type and materials to permits and inspections, so you know what to expect before you break ground.
Step 1: Choose Your Pool Type
Each pool type comes with different costs, installation timelines, and long-term maintenance demands. Here is an honest look at each option.
In-Ground Pools
In-ground pools are the most popular choice for permanent residential installations. They offer the most flexibility in shape, size, depth, and features. You can build a freeform lagoon, a lap pool, or a geometric design that matches your home’s architecture. They also add the most resale value to your property.
Cost range: $35,000-$100,000+ depending on size, material, and features.
Installation timeline: 6-12 weeks for most projects.
Lifespan: 20-50+ years depending on the material.
Above-Ground Pools
Above-ground pools are the most affordable and fastest way to get a pool. Modern designs look far better than the flimsy options from decades past — steel-wall and resin-frame models can be paired with decking to create a polished look. They do not require excavation, which means no heavy equipment in your yard and no risk of hitting underground utilities.
The trade-off is longevity. Most above-ground pools last 7-15 years before the liner or frame needs replacing. They also have limited depth (typically 48-54 inches) and fixed shapes. For a detailed comparison, read our guide on above-ground vs. inground pools.
Cost range: $1,500-$15,000 depending on size and quality.
Installation timeline: 1-3 days.
Lifespan: 7-15 years.
Fiberglass Pools
Fiberglass pools arrive as a pre-molded one-piece shell that gets lowered into an excavated hole. Installation is fast because there is no curing time — once the shell is set, backfilled, and plumbed, you can fill it. The smooth gelcoat surface resists algae growth and requires less chemical treatment than concrete.
The limitation is customization. You are choosing from the manufacturer’s existing mold shapes and sizes. If you want a custom shape or a pool longer than about 40 feet, fiberglass is not the right choice.
Cost range: $25,000-$65,000 installed.
Installation timeline: 2-4 weeks.
Lifespan: 25-30+ years.
Swim Spas
A swim spa is a compact unit (typically 12-20 feet long) that generates a current you swim against, giving you a lap-swimming experience in a fraction of the space. Most models include a hot tub section on one end. They are self-contained with built-in filtration and heating, so installation is simpler than a traditional pool — they sit on a reinforced concrete pad and plug into your electrical panel.
Swim spas work well for homeowners with small yards or those who primarily want a pool for exercise rather than recreation. They are not ideal for pool parties, games, or multiple swimmers at once.
Cost range: $15,000-$40,000.
Installation timeline: Delivery and setup in 1-2 days (plus pad preparation).
Portable and Inflatable Pools
Portable pools range from large inflatable rings to semi-permanent steel-frame setups. They require no permits, no excavation, and minimal commitment. The largest models (18-24 feet round) provide enough space for casual swimming and basic pool games.
These are a good option if you rent your home, want to test whether your family will use a pool before investing in a permanent one, or need something for a few seasons. They will not increase your home’s value and typically last 2-5 years.
Cost range: $200-$3,000.
Setup timeline: 1-4 hours.
Step 2: Pick Your Construction Material
If you are going with an in-ground pool, you will need to choose between three main construction materials.
Concrete (Gunite/Shotcrete)
Concrete is the most versatile and durable option. Gunite (dry mix) or shotcrete (wet mix) is sprayed over a rebar framework, then finished with plaster, pebble aggregate, or tile. You get complete control over shape, size, depth, and features.
Pros: Unlimited design flexibility, longest lifespan (50+ years with proper maintenance), accommodates any depth or feature, can be resurfaced rather than replaced.
Cons: Highest cost, longest build time (8-12 weeks), rough surface can be abrasive on bare feet, requires more chemical maintenance because the porous surface promotes algae, needs resurfacing every 10-15 years.
Fiberglass
As described above, fiberglass is a pre-formed shell. The smooth, non-porous surface is its biggest maintenance advantage.
Pros: Fast installation, low maintenance, smooth surface, algae-resistant, no resurfacing needed.
Cons: Limited shapes and sizes, cannot be customized once manufactured, potential for bulging if groundwater pressure is not managed during installation.
Vinyl Liner
A vinyl liner pool uses a steel, polymer, or wood frame with a custom-cut vinyl sheet as the waterproof barrier. The liner conforms to the pool shape and is held in place by a track system at the top edge.
Pros: Lowest in-ground cost, smooth and comfortable surface, wide variety of patterns and colors, good for colder climates where freeze-thaw can crack concrete.
Cons: Liner needs replacement every 5-9 years ($3,000-$6,000), vulnerable to punctures and tears, limited depth and feature options compared to concrete.
Step 3: Choose the Right Location
Where you put your pool affects everything from construction cost to daily enjoyment. Consider these factors before committing to a spot.
Sun exposure. A pool that gets 6+ hours of direct sun stays warmer naturally and reduces heating costs. In very hot climates, you may want partial afternoon shade to keep the water from getting uncomfortably warm.
Proximity to the house. Closer is almost always better. A pool near the back door gets used more often, is easier to monitor when kids are swimming, and costs less to run plumbing and electrical lines.
Underground utilities. Call 811 (the national dig hotline) before you plan anything. Gas lines, water mains, sewer pipes, and electrical conduits can all derail your pool placement. Moving utilities is expensive and sometimes impossible.
Drainage and grade. Your pool should not be at the lowest point of your property, where runoff water collects. Water flowing into the pool after rainstorms brings dirt, debris, and potential contamination.
Trees. Overhanging trees mean constant leaf cleanup and potential root intrusion into pool plumbing. Plan your pool landscaping with low-maintenance plantings set back from the pool edge.
Setback requirements. Local building codes specify minimum distances from property lines, structures, and easements. Check these before you fall in love with a specific location.
Step 4: Determine the Size and Depth
Pool size depends on how you plan to use it. Here are some guidelines.
Lounging and wading: A pool as small as 10×20 feet works fine. Depth of 3-4 feet throughout.
Family recreation and games: 15×30 feet minimum. A mix of shallow (3.5 feet) and deeper (5-6 feet) areas gives flexibility. If you plan to play water volleyball, the ideal pool depth is between 3.5 and 4.5 feet.
Lap swimming: At least 40 feet long and 8-10 feet wide per lane. Standard lap pool depth is 3.5-5 feet.
Diving: A diving board requires a minimum depth of 8-9 feet in the diving zone, with a gradual slope to shallower areas. Check your local codes — some jurisdictions have stricter depth requirements.
General rule of thumb: Build slightly larger than you think you need. Nobody has ever said “I wish my pool were smaller.” But plenty of people wish they had gone bigger.
Step 5: Plan Your Features
Features add cost but also add significant enjoyment. Decide which ones matter to you before getting quotes so builders price the same scope.
Heating. Gas heaters warm the water fastest, heat pumps are the most energy-efficient, and solar heaters are the cheapest to operate but slowest to warm. If you want to extend your swimming season, heating is the single best investment. Consider the differences between saltwater and chlorine systems as well.
Lighting. LED pool lights extend usable hours into the evening and dramatically improve the look of your pool at night. Color-changing LEDs are popular and surprisingly affordable.
Water features. Waterfalls, bubblers, deck jets, and spillover spas add visual appeal and the sound of moving water. They also help with circulation.
Automation. Smart pool controllers let you manage pumps, heaters, lights, and chemical dosing from your phone. The upfront cost pays for itself in convenience and efficiency.
Safety features. Pool fencing, self-closing gates, pool alarms, and safety covers are required by code in most areas. Budget for these from the start — retrofitting is more expensive.
Step 6: Get Multiple Quotes
Contact at least three licensed pool builders for quotes. When comparing bids, make sure each builder is pricing the same scope of work. Common items that get left out of low bids include:
- Permits and engineering
- Electrical work and gas lines
- Decking and coping
- Fencing and safety barriers
- Landscaping restoration
- Pool cover
- First season of chemicals and startup
Ask each builder for references and visit at least one completed pool in person. Look for clean tile work, level coping, smooth plaster, and a well-functioning filtration system.
Step 7: Handle Permits and Inspections
Every municipality has different permit requirements, but almost all require a building permit for in-ground pool construction. Your builder should handle the permit application, but you should understand the process.
Typical permits needed: Building permit, electrical permit, plumbing permit, and in some areas a separate fence permit.
Common inspections: Pre-dig (utility clearance), steel/rebar (before shotcrete), plumbing (before backfill), electrical (before burial), barrier/fence (before filling), and final inspection.
Timeline impact: Permit approval can take 2-6 weeks depending on your municipality. Factor this into your project timeline, especially if you are targeting a specific completion date.
HOA approval. If you live in a homeowners association, you likely need architectural committee approval before applying for permits. This can add another 2-4 weeks.
Step 8: Construction and Final Inspection
Once permits are approved and your builder is scheduled, the typical in-ground pool construction sequence looks like this:
- Excavation (1-2 days)
- Steel/rebar framework (1-2 days)
- Plumbing and electrical rough-in (2-3 days)
- Shell construction — gunite, fiberglass set, or liner install (1-3 days)
- Curing time for concrete pools (7-28 days)
- Tile, coping, and decking (3-7 days)
- Equipment installation (1-2 days)
- Interior finish — plaster, pebble, or liner (1-2 days)
- Fill and startup (1-2 days)
- Final inspection
After the final inspection passes, your builder will walk you through equipment operation, chemical balancing, and maintenance basics. The first few weeks of water chemistry management are critical — follow the startup instructions carefully.
Getting Ready for Your First Swim
Once your pool is built and inspected, check our guide on how to open your pool for summer for a step-by-step startup checklist. Think about how much it will cost to maintain over time by reading how much does a pool cost for the full picture, including ongoing annual expenses.
Building a pool is a significant investment of money and time, but with thorough planning, you end up with something your family uses every day for decades. Take each step seriously, hire a reputable builder, and do not rush the planning phase. The pool itself gets built in weeks — the decisions you make beforehand last a lifetime.
