The build price gets all the attention, but the number that actually lives in your monthly budget is upkeep. Here's what owning a pool in Texas realistically costs per year.
The recurring basics
Chemicals: roughly $500–$1,200/year DIY, depending on pool size and whether you run a salt system. Texas's long swim season and intense sun burn through chlorine faster than in cooler states, so budget toward the higher end for an uncovered pool.
Electricity: the pump is the main draw — often $40–$120/month during heavy-run summer months, less in winter. A variable-speed pump (now standard on new builds and required by federal efficiency rules) can cut that dramatically versus an older single-speed unit.
Water: evaporation is real here. A Texas pool can lose a quarter-inch or more per day in August, meaning meaningful refill costs across a summer, plus whatever splash-out the kids contribute.
Professional service: weekly pool service typically runs $120–$250/month depending on market and scope. Many Texas owners do their own chemistry in the mild months and hire out for summer.
All in, most Texas homeowners land somewhere around $3,000–$6,000 per year, with heated pools and full-service accounts running higher.
The costs people forget
Homeowner's insurance usually rises modestly with a pool (it's an attractive nuisance in insurer language), and some carriers require specific fencing. Property taxes may tick up as your assessed value rises. And equipment is not forever: pumps and heaters have finite lifespans, filters need periodic cartridge or media replacement, and salt cells are consumables replaced every 3–7 years.
The big one: resurfacing
Plaster is not permanent. A gunite pool typically needs replastering every 10–15 years at roughly $10,000–$20,000 depending on size and finish. Nobody enjoys this line item, but pretending it doesn't exist is how pool budgets go wrong. Set aside a small monthly amount from year one and it becomes a non-event.
How to keep it lower
Run a variable-speed pump at lower speeds for longer periods rather than high speeds briefly. Use a cover if you'll tolerate one — it slashes evaporation and chemical loss. Keep chemistry balanced consistently rather than correcting swings, which wastes chemicals and stresses surfaces. And when you build, spend on quality equipment and finish: cheap surfaces and undersized equipment cost more over a decade than they save on day one.
Ask any builder you interview what they expect annual upkeep to run on the specific pool they're proposing — a straight answer is a good sign. Compare builders by city in the directory.
