A mid-size vinyl liner pool (about 16×32) installed in Colorado typically runs $51,500–$80,500 with standard equipment and a basic deck. The liner itself is replaced every eight to twelve years at $4,600–$8,000:
| Job | Typical Colorado price |
|---|---|
| Small vinyl liner pool (about 12×24), installed | $40,500–$57,500 |
| Mid-size pool (about 16×32), installed | $51,500–$80,500 |
| Large pool (about 20×40), installed | $75,000–$109,000+ |
| Polymer wall upgrade over steel | $2,300–$5,800 |
| Vinyl-covered steps, benches or sun ledge | $2,300–$6,900 |
| Decking and coping | $6,000–$17,500 |
| Equipment upgrades (heater, salt, automation) | $3,500–$10,500 |
| Safety cover | $2,300–$4,600 |
| Permits and inspections | $500–$2,900 |
| Liner replacement, later (every 8–12 years) | $4,600–$8,000 |
Colorado pricing is above the national baseline used for these estimates, mainly on labor and permitting. Rectangles cost less than freeforms, steel walls less than polymer, and a thicker liner (27 or 28 mil) adds a little up front and years to the first replacement.
The second liner is part of the real cost of a vinyl pool — ask every bidder what a replacement will run and how long the first one should last.

Expansive bentonite clay is the Colorado headline: it swells dramatically with moisture, so soils reports, structural engineering, and sometimes pier systems aren't upsells — they're how shells survive. Freeze-thaw cycling drives deck and plumbing specs, and hail shapes equipment placement. Vinyl liner pools dominate freezing climates because the wall system tolerates frost heave better than a rigid finish and the liner is forgiving of winterization.
The largest listed markets are Denver (2 companies).
Ask about the wall system, floor material and liner gauge, confirm the liner warranty in writing, and get a price for the first liner replacement now so you know the long-term cost. Compare at least three itemized bids for the same size and shape. Colorado licenses contractors at the city and county level (Denver-metro jurisdictions each run their own programs) — verify local licensing and insurance, and confirm the electrician on the equipment permit. Pool permits and residential-code barrier requirements run through your municipality; HOA review is near-universal in newer developments.

Eight to twelve years is typical, longer with a thicker liner, balanced water and a cover. Fading, brittleness, wrinkles and leaks at seams or fittings are the signs it is time. Replacement is a one-to-three-day job once the new liner arrives, and the pool is otherwise unchanged.
Usually four to eight weeks after permits: a few days to dig and set the walls, a week or two for plumbing, the floor and the deck, then the liner is installed and the pool filled in a day. Custom liners are made to measure and can take two to four weeks to arrive. Liners install best in warm weather, so spring and summer book first.
The smooth surface uses fewer chemicals than plaster and never needs resurfacing, but the liner itself is the recurring cost — roughly the price of a resurfacing spread over a similar interval. Keep the water balanced, avoid letting the level drop, and use a cover to extend liner life.
The outdoor season in Colorado runs late May through mid-September — about 4 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. Late May through mid-September, with intense high-altitude UV and cool nights that make heaters standard. Sunny winter days tempt, but hard freezes rule — full winterization is the norm.

Both perform well. Galvanized steel panels are the lower-cost standard and very strong; polymer (plastic) panels cost more but cannot rust and suit salt systems, coastal air and wet soils. Either way, ask how the panels are braced and how the deck is tied to the walls so the coping does not shift.
Yes — walls are built on site, so the depth profile is yours to choose, including diving depths. Spas are usually added as a separate fiberglass or gunite unit beside the pool rather than inside the liner structure. Tanning ledges and benches are formed and then covered with the liner.
