Cost by pool type
Chicago-area pricing runs above national averages because of our freeze-thaw climate: deeper frost footings, freeze-rated plumbing, and a shorter build season all add cost. The construction type is the biggest single price driver, so it is the first decision worth making.
- Vinyl liner: the lowest upfront cost of the three. Budget for a new liner every 8-12 years as part of owning one.
- Fiberglass: mid-range upfront, and the lowest lifetime maintenance. Sizes are limited to shells that can be trucked in.
- Gunite / concrete: the highest cost and the widest range, because it is fully custom in shape, depth and finish. Longest build time and the most ongoing care.
What pushes the price up (or down)
Two identical pools can differ by tens of thousands of dollars based on the yard they go into and what surrounds them. The big variables:
- Site work: access for excavation equipment, soil conditions, drainage, and slope
- Decking and patio: concrete, pavers, or travertine around the pool is often 15-25% of the project
- Equipment: heaters, automation, salt systems, UV sanitizers, and variable-speed pumps
- Water features: spas, tanning ledges, waterfalls, and lighting
- Fencing: Illinois requires barriers around residential pools; municipal codes vary by town
- Permits: Kane County and municipal permits add fees and lead time. Budget weeks, not days
The ongoing costs nobody budgets for
Plan on annual operating costs on top of construction. In the Fox Valley a realistic yearly picture looks like:
- Opening and closing: quoted per pool, once each per season
- Chemicals: $600-$1,200 per season, depending on pool size and sanitizer system
- Electricity: $50-$150 per month while running, less with a variable-speed pump
- Gas heating: $200-$500+ per month if you heat consistently. A cover cuts this dramatically
Timeline: when to start planning
Vinyl and fiberglass installations typically take 6-12 weeks once permitted; gunite builds run 3-6 months. Permits and HOA approvals add lead time before any digging starts. If you want to swim next summer, start the design conversation in fall or winter. Spring is when everyone else calls.
