Lighting
Lights average $100 to $300 each for 50-watt built-in lights. Lighting can set the mood and provide some safety for night swimming. Traditional incandescent lights and energy-efficient LED lights are available for various prices, depending on features such as light color, floating or fixed, and output.
Heater
A pool heater installation costs $1,500 to $4,000, and the operating cost will range from $100 to $600 monthly.
Hot Tub
A basic hot tub can add $5,000 to $8,000 to your base price. If you need excavation service and customization, installing a built-in hot tub costs $15,000 to $20,000.
Backyard and Landscaping
Landscaping costs range from $1,500 to $5,200. However, the price can go up to $20,000 for significant and involved landscaping.
Retaining walls cost about $3,200–$13,000 to create a level yard to keep soil and sediment from eroding into your pool or onto your patio or deck. Retaining walls also provide additional support to slides and water features.
Semi in-ground pools cost more than an in-ground unit for a 12-by-24-foot model. They can be built directly into slopes and give you the opportunity to install an infinity edge, costing an additional $15,000–$20,000.
The cost to reslope your land is about $1,000–$3,000. Reuse the excavated dirt to level your yard, saving $1,000 or more on removal fees.
Landscaping rocks cost $460–$1,000. Available in natural and artificial, the natural look of stone makes for a relaxing escape, with the price heavily depending on the type, amount, and configuration.
Pool Deck
Pool decks and coping cost $3,000 to $12,000. If you choose a more elaborate design or expensive material, the fees will increase.
Waterfall or Water Feature
A waterfall installation costs $1,500 to $5,000 or more, and elaborate ones can reach $30,000. Budget 10% to 15% of your total project for a water feature, which can create an attractive focal point and goes well with elevated hot tubs and spas.
Water Slide and Diving Board
On average, water slides can cost $1,000 to $14,000, depending on the design, manufacturer, and features such as water jets. Diving boards can cost $300 to $5,000 on average. Installation pricing depends on your type and local codes and requirements.
Fencing or Enclosing Your Pool
Your homeowners association will likely require you to fence in your pool. Remember to always install childproof locks and latches for added safety.
Fence installation costs $13–$50 per linear foot, or a total of $1,500–$5,000.
Gates add $200–$350 each.
Removable fences cost $100–$500 per panel and include locks and latches to keep them in place.
Pool covers cost $700–$2,200 with installation. A higher-end option with automatic and security options will be between $1,000–$15,000.
Pool enclosures cost between $5,000–$15,000. Installing a pool enclosure will extend your swimming season because they retain some heat and keep the water cleaner for longer.
Fireplace
Outdoor fireplaces cost between $1,500 and $20,000, including installation and depending on the materials you choose. Expect to pay $300 to $1,000 for a contractor to install a premade fireplace kit. Custom projects will cost much more, but anticipate about $70 to $150 per hour of labor.
