How Much To Run A Hot Tub

So, you’ve finally done it. You’ve taken the plunge into hot tub ownership. Maybe you pictured yourself soaking under the stars, a drink in hand, while the neighbor mows his lawn in jealous silence. But then the first electricity bill arrives, and suddenly that jealousy feels a little more like pity. The truth is, running a hot tub is a bit like adopting a very hungry, very warm pet—one that drinks electricity instead of kibble.

Let’s break down the real cost, the kind your wallet feels every month. On average, expect to drop between $20 and $60 per month on electricity alone. That’s the price of a nice dinner out, or two fancy coffees you tell yourself you’ll skip. But like a stubborn child, your hot tub doesn’t care about your budgeting app. It wants to stay at 104°F, always.

The Energy Hog: Winter vs. Summer

If you live somewhere with actual seasons, prepare for a plot twist. In the summer, your hot tub is a chilled-out teenager—it sipped power just to keep the pump running. But in the winter? Oh, it becomes a ravenous beast, burning energy to fight off the cold air. Imagine your water heater trying to heat a swimming pool with a hairdryer. That’s your January bill.

A good cover is your only shield. Invest in a thick, well-insulated cover, and you’ll save $10 to $20 a month. It’s like putting a winter coat on a shivering friend—except that friend is your bank account. And no, that flimsy bubble wrap from Amazon won’t cut it. Your hot tub will laugh at it, then double its electricity appetite.

The Hidden Hungers: Chemicals and Filters

Electricity gets all the attention, but chemicals are the sneaky sidekick that empties your pockets. You’ll spend roughly $15 to $30 per month on chlorine, shock, pH balancers, and the occasional algaecide when you forget to check it for a week. Think of it like buying a new bottle of shampoo every month because you keep leaving the cap off—except this shampoo is toxic if you drink it.

Filters are the unsung heroes that demand sacrifice. A new set of filters costs about $30 to $50, and you should replace them every 3–6 months. If you skip this, your water turns into a murky swamp that smells like a gym locker. Nobody wants to soak in a gym locker, no matter how cold the beer is.

The Water Bill: A Gentle Nudge

Refilling the tub (about 300–400 gallons) once every three months adds maybe $5 to $10 to your water bill. That’s less than the cost of a single latte, which is nice. But here’s the catch: you’ll waste more water wrestling with the hose than the actual fill. I once spent twenty minutes trying to unkink a hose that had twisted itself into a pretzel. That water is free, but your sanity is not.

Maintenance: The Surprise Dates

Then there’s the occasional repair. A pump can fail, a heater can go kaput, or a jet can clog with calcium. These unplanned dates cost anywhere from $100 to $500 per incident. It’s like when your car makes a weird noise and you pretend it’s fine, then it dies on the highway. Except your hot tub doesn’t move—it just sits there, mocking you with its stillness.

DIY maintenance is your friend. Learn to clean the filters with a garden hose sprayer. Buy a simple test strip kit ($10 for 50 strips). Avoid the expensive “water treatment” packages sold by the tub dealer—they’re like paying a premium for a fancy water bottle that does the same thing as a mason jar. Your wallet will thank you.

The Big Picture: Is It Worth It?

So, adding it all up: electricity, chemicals, filters, and water, you’re looking at $50 to $120 per month. That’s roughly the cost of a Netflix subscription plus a pizza delivery twice a month. But the question isn’t “Can I afford it?”—it’s “Do I use it enough to justify it?”

If you soak three times a week, each session costs you about $1.50 to $3.00. That’s cheaper than a therapy session, and you get to wear a swimsuit. On the other hand, if you treat it like a lawn ornament that you wave at from the kitchen window, you’re paying a premium for a very large, heated dust collector.

My advice? Use it, darn it. Invite friends over. Bribe yourself with a waterproof phone holder. The cost doesn’t sting as much when you’re the one floating, steam rising, while the neighbors scrape ice off their windshields. Just don’t look at your electric bill until spring—your heart might need a defibrillator.

And if anyone asks how much it costs to run, just smile and say, “About the same as a monthly car payment.” Then change the subject to how great the jets feel on your lower back. Trust me, they’ll nod in envy. Even if their wallet is secretly relieved.
