Indoor pools are great but they cost a substantial amount of money to be built. If you’re building an indoor swimming pool with the help of a pool contractor and looking for ways to lower the costs, here are a few things you can do.

Tips For Reducing The Cost Of Building An Indoor Pool

Choose Affordable Materials

The shell and interior finish make up a big share of your budget, so pick materials that deliver solid performance without the premium price. A vinyl liner costs far less than tile or polished aggregates and can be replaced affordably if it wears out.

If you prefer concrete, standard white plaster is much cheaper than pebble finishes or glass tile. On the other hand, fiberglass shells can also save money because they install quickly, which cuts labor hours. Ask the contractor to price at least two finish options so you can see the real savings side by side.

Keep The Shape Simple (Rectangle Or Square)

Curves, custom angles, and freeform designs look impressive, but they drive up forming, excavation, and finishing costs fast. A simple rectangle shape is the cheapest to build because it uses standard forms, simplifies plumbing, and wastes less space.

Straight edges also make covers, liners, and decking easier to fit, which lowers material waste. If you want visual interest, achieve it with coping choices, lighting, or landscaping instead of geometry. Save the dramatic shapes for a future project; a clean rectangular pool delivers the same swimming experience at a noticeably lower price.

Consider A Smaller And Shallower Pool

Every extra foot of length, width, and depth adds excavation, structural material, water, heating capacity, and chemical costs. Most families swim, play, and relax in a modest pool, so resist the urge to build big in-ground pool when you can make do with a small one.

A shallower pool, around four feet deep at its deepest point, needs less digging and less steel, and it heats more cheaply for years to come. Consider a compact lap configuration or a smaller footprint paired with a spacious deck. You can always add features later, but you cannot easily shrink a pool once it is in the ground.

Finalize The Design Before Construction Begins

Change orders are among the most expensive surprises in any pool project. Once the crew is on site, moving a skimmer, upgrading a finish, or rerouting plumbing means downtime, wasted materials, and extra labor charges. Spend some time on the planning stage: walk the space, confirm dimensions, choose every fixture and finish, and sign off on detailed drawings.

A complete set of plans lets contractors quote accurately and locks your price in writing. A few extra weeks of decision-making up front can save you thousands of dollars and weeks of delays later.

Get Multiple Quotes

Never accept the first quote you receive. Get detailed estimates from at least three licensed, reputable builders, and make sure each bid covers the same scope so you can compare them fairly. Request itemized pricing for excavation, shell construction, plumbing, electrical work, and the dehumidification system, because indoor pools need moisture control that some builders underprice.

Remember to watch out for quotes that seem too good to be true. Unusually low costs often mean corners will be cut. Mentioning that you are comparing several bids politely often encourages builders to sharpen their pencils and offer a better price.

Build During The Off-Season

Pool builders get flooded with requests in spring and early summer, and demand drives pricing. Schedule your project for late fall or winter when crews are hungry for work; many will discount labor or throw in upgrades just to keep their teams busy. Materials like concrete, steel, and pipes also tend to be cheaper and more available during slow months.

An off-season start means your pool may be ready the moment warm weather arrives, so you lose nothing. Just confirm your builder can properly cure concrete or set a fiberglass shell in cold conditions. This tip applies to building other outdoor structures as well like patios, decks, etc. Consult patio contractors Long Island who offer discounts during the off-season.

Choose The Location Wisely

Where you put the pool affects its cost more than you would think. Building close to existing water, sewer, gas, and electrical lines shortens utility runs and lowers connection fees. Keeping the equipment room directly adjacent to the pool, or sharing a wall with it, cuts hundreds of dollars in piping and reduces heat loss through long pipe runs.

Avoid areas that need retaining walls, major grading, or extra structural support for the surrounding floor. Your contractor can mark utility locations on the plans before work begins, and a few feet of planning can save real money.

DIY Simpler Tasks

Labor is a huge line item, so look for tasks you can safely take on. Hauling debris, cleaning the site, final grading around the enclosure, painting walls, and pool landscaping are all realistic do-it-yourself jobs. Some homeowners even handle basic excavation for accessible backyards, though indoor projects with tight access usually need professionals.

But before you grab a shovel, talk with your contractor about which tasks they will allow, since liability and warranty rules vary. Coordinating your own dumpster rentals or material deliveries can also trim the invoice without touching any technical work.

Skip The Unnecessary Extras

Waterfalls, sheer descents, built-in slides, fiber-optic lighting, and infinity edges add drama and thousands of dollars. Inside a pool enclosure, dramatic water features also increase humidity, which means a larger dehumidification system and higher operating costs.

So, stick to the essentials: a sturdy ladder or wide steps, standard returns, and one or two efficient light fixtures. Even a diving board or a spa spillover can trigger structural and safety upgrades that inflate the budget. You can always add a feature in a year or two once you know how you actually use the pool.

Reuse Excavated Soil And Leftover Materials

Digging an in-ground pool produces a huge amount of soil, and paying to haul it away gets expensive quickly. Ask your contractor whether the excavated dirt can stay on site for grading, berms, or raised planting beds around the building. Leftover concrete can be crushed for drainage fill, and cutoffs of pipe or lumber often serve other parts of the project.

Every load you do not pay to truck off site, and every load of fill you do not buy back later, is pure savings. Discuss disposal and reuse plans before the contract is signed.

Phase The Project And Add Non-Essential Later

You do not have to finish everything at once. Get the pool structure, plumbing, filtration, heating, and moisture control done right the first time, then delay the finishing touches. Decorative flooring, custom lighting scenes, furniture, artwork, and surrounding landscaping can be added over subsequent seasons as budget allows.

Building the shell and equipment with future additions in mind, such as extra conduit or roughed-in plumbing lines, costs little now and prevents expensive demolition later. Phasing also spreads the expense across many years and lets you learn how the space works before spending on refinements.

Conclusion

An indoor pool doesn’t have to be too expensive. You can build a cheaper one by following these tips. But hiring a good pool builder Long Island is critical who can plan the project and also suggest you practical ways to save money.
