If you own a hot tub (or you’re about to), one question comes up fast: Should you keep it running all year—or shut it down seasonally?
For most owners—especially in climates with real winters—keeping your hot tub running year-round is usually the easiest and safest option, as long as you do it efficiently. Here’s how to decide, what it costs, and what to expect.
The quick answer (for most hot tub owners)
Keep it running year-round if…
- You live where temperatures drop near freezing (winter shutdown increases freeze-damage risk if not winterized correctly)
- You use it at least a few times a month
- You want less hassle and more consistent water quality
Consider shutting it down if…
- You truly won’t use it for months and
- You’re prepared to winterize it correctly (or have a professional do it)
Pros of keeping your hot tub running year-round
1) Convenience: it’s always ready
No draining, deep cleaning, refilling, heating from cold water, or rebalancing from scratch. You keep a steady routine.
2) More consistent water care
Stable temperature + consistent filtration typically makes the water easier to maintain. The CDC emphasizes maintaining proper disinfectant and pH levels for safer soaking—consistent routines make that easier
3) Better “real life” value
If you bought a hot tub for stress relief, sleep, sore muscles, or simple joy—turning it off for long stretches can quietly turn ownership into a project instead of a lifestyle.
Cons of keeping it running
1) Monthly electricity cost
Energy cost depends on your:
- local electricity rate ($/kWh)
- outdoor temps (winter costs more)
- how often you open the cover
- insulation quality + cover quality
- set temperature
Utility guidance breaks down how heater/pump wattage and your electric rate affect cost.
2) You still have maintenance
Even if you don’t use it daily, you still need basics like:
- water testing
- sanitizer maintenance
- filter cleaning
- cover care
3) Better “real life” value
If you bought a hot tub for stress relief, sleep, sore muscles, or simple joy—turning it off for long stretches can quietly turn ownership into a project instead of a lifestyle.
What it costs to run a hot tub year-round
There’s no single number, but here’s what drives cost:
Temperature choices matter
Many owners soak around 100–104°F, and public health guidance commonly recommends not exceeding 104°F (40°C).
If you want to reduce cost, you can often lower your set temp slightly when you know you won’t use it for a few days.
The cover is your best “money saver”
Evaporation is a major source of heat loss. The U.S. Department of Energy notes that covering water when not in use is the single most effective way to reduce heating costs (the same heat-loss concept applies to spas).
EPA also notes covers reduce evaporation and help retain heat, saving water and energy.
Bottom line: If you keep it running, your cover habits matter a lot.
If you’re thinking about turning it off seasonally…
Here’s the part many owners underestimate: shutting a hot tub down isn’t “turning a switch off.” It typically means:
- draining fully
- removing water from plumbing lines
- preventing residual water from freezing
- cleaning + drying
- covering and protecting equipment
If you’re in a freezing climate and the tub isn’t properly winterized, freeze damage can get expensive fast. (This is why many owners simply keep it running.)
How to run your hot tub year-round more efficiently (without ruining comfort)
Try these high-impact habits:
- Keep the cover closed and latched when not in use
- Use a sensible temperature strategy (comfort + safety; don’t exceed 104°F)
- Maintain sanitizer + pH consistently (easier than “fixing” water later)
- Clean/replace filters on schedule (your dealer can guide you based on usage)
- Plan electrical correctly (safe, code-compliant GFCI/disconnect requirements fall under NEC guidance for spas/hot tubs)
