If you’re reading this, chances are you’ve walked past a rack of outdoor spa brochures at a trade show, or maybe you’ve even tested a few at a backyard showcase—we’re the people who build those, so we’ve heard every question under the sun when it comes to hot tubs: Is it just a fancy jacuzzi for showing off? Or is there something actually risky about sitting in warm water with a bunch of other people? Today, I’m breaking down the real health stuff, no fluff, no corporate jargon, just what you need to know before you plop down $X on an outdoor spa (and yeah, I’ll be the supplier spilling the tea, so take this as insider info, not a sales pitch). Outdoor Spa
First, let’s get one thing straight: outdoor spas aren’t like indoor bath tubs. They’re exposed to the elements—dust, pollen, rain, even random debris from trees—and if you’re not keeping up with maintenance, that’s where the first health risks pop up. I’ve seen it a hundred times: a customer buys a spa, sets it up, and then forgets to check the chemical levels for a week. What happens then? Bacteria, mostly. The big one here is Legionella. I don’t know how many times I’ve had a service tech show up to a client’s house and find Legionella levels off the charts. Legionella grows in warm water (that’s why spas are perfect for it, since we heat them to 100-104°F) and stagnant conditions. If you inhale water droplets from a poorly maintained spa (like when someone is jets massaging and mist is flying everywhere), you can get Legionnaires’ disease. That’s the serious one—pneumonia, basically, especially bad for people with weak immune systems, seniors, or folks with chronic illnesses.
Wait, but that’s on the maintenance side, right? You don’t have to skimp on chemicals. We always tell our customers: test your water twice a week. Keep the chlorine or bromine levels where they’re supposed to be—chlorine should be 2-4 ppm, bromine 3-5 ppm. If you slack on that, you’re not just fighting bacteria; you’re also dealing with other yucky stuff like pseudomonas. That’s the one that causes hot tub folliculitis—those red, itchy bumps on your legs or torso a few days after soaking. I’ve seen people panic, thinking they have some weird rash, and it’s just from a spa that wasn’t cleaned properly. And yeah, even if you’re the only one using it, if you don’t shock it every few weeks (that’s a higher dose of chemicals to kill all the gunk), you’re still at risk.
Next up, what about temperature? A lot of people think “warmer is better” for relaxation, but that’s not true for everyone. Pregnant people, for example, have to be super careful. Spas heat your core body temp, and if you get too hot—over 102°F for more than 10 minutes—there’s a risk of neural tube defects in early pregnancy. We’ve had a few expectant customers reach out, and we always advise them to check with their OB first, and keep the temp down to 98-100°F, max. Even for non-pregnant folks, if you have heart issues, high blood pressure, or are on medication that makes you drowsy (some antihistamines, blood pressure meds), sitting in a hot spa can make your blood vessels dilate, leading to dizziness, fainting, or even a heart strain. I’ve had a customer with a history of mild hypertension show up to a demo, sit in the spa for 20 minutes, and say he felt lightheaded—turns out he’d forgotten to take his meds that morning, and the spa amplified that. It’s not that spas are bad, just that they’re not one-size-fits-all.
Then there’s the water itself—even if you’re maintaining chemicals, old water can build up stuff like heavy metals or mineral scales. Wait, no, I’m not talking about “hard water” stains, but things like copper from the spa’s heater or pipes. If the copper levels are too high (over 0.5 ppm), that can cause eye or skin irritation, even stomach issues if you’re drinking water from the spa (don’t drink the spa water, obviously!). Also, if you’re someone with sensitive skin or eczema, the combination of warm water and harsh chemicals can dry you out, make your eczema flare up. We tell people with skin conditions to use a gentle moisturizer before getting in, and rinse off right after soaking—no lingering in warm, chemical-laden water all night.
But let’s be real, most of these risks are avoidable. Here’s the thing: as an outdoor spa supplier, we don’t just sell the tub and walk away. We include a quick start guide that walks you through chemical testing, maintenance schedules, temperature limits, and even who should skip the spa (or at least clear it with a doctor). We’ve even got a team that does free check-ups for the first 3 months after installation, just to make sure the customer’s not messing up the water. I can’t tell you how many times I’ve talked a first-time spa owner off the ledge when they text at 9 PM panicking because their test strip is a little off—no panic, just adjust the chemicals, that’s it.
Wait, are there any other weird risks? Oh, right! I almost forgot about slips and falls. Outdoor spas are usually placed on a deck or patio, and when you get out, your feet are wet. I’ve seen so many people slip—even ourselves, after a long day at the warehouse, walking back to the office with wet feet on a concrete floor. That’s why we always recommend installing non-slip mats around the spa, and maybe a small handrail if the spa’s raised off the ground. It’s not a health risk you hear a lot about, but it’s a real one—spas aren’t just for sitting in, they’re places where you move around, so safety around the area matters too.
Another one: water quality from the source? Wait, if you fill your spa with tap water that has a lot of chlorine or chloramine, that can react with the spa’s chemicals and create chloramines, which are the stinky stuff you smell around poorly maintained spas. Those chloramines are irritants—they can make your eyes burn, your nose run, even trigger asthma attacks if you’re prone to them. So we advise customers to let tap water sit for 24 hours before filling the spa, to let the extra chlorine evaporate. It’s a simple step, but it makes a big difference.
Now, let’s address the elephant in the room: is there any way to use an outdoor spa safely? Absolutely. Let’s list the easy stuff we tell everyone: 1. Test your water 2x a week, adjust chemicals as needed. 2. Keep the temperature at 100°F or below for most people, pregnant people stick to 98-100. 3. Shower before getting in (to wash off sweat, sunscreen, dirt—those mess with chemical levels) and after (to rinse off chemicals). 4. Don’t go in if you have an open wound or a contagious illness (like a cold or flu—you don’t want to spread germs, same as you wouldn’t swim in a pool sick). 5. Keep the area around the spa non-slip, no clutter.
I know, I sound like a broken record, but as someone who’s been in this game for 10 years, I’ve seen the good and the bad. I’ve seen a family use their spa every weekend, maintain it right, and have zero issues. I’ve also seen a customer buy a spa, leave it covered for 2 months while they were on vacation, and end up with a bacteria bloom that required a whole spa deep clean (and a visit to the doctor for their kid who got folliculitis). The difference? They took 10 minutes a week to check the chemicals. That’s all it takes.
Wait, but what about if you’re shopping for a new outdoor spa, like, right now? Let me be honest with you: not all outdoor spas are built the same. Some cheap ones have flimsy filters that don’t catch bacteria, or cheap heaters that can’t regulate temperature, leading to overheating. That’s why a good supplier (ahem, us) uses commercial-grade filters, stainless steel heaters that keep temp consistent, and even has a self-cleaning feature that shocks the water automatically every few days. That cuts down on so much maintenance hassle, and reduces the risk of bacteria way more than a cheap model.
Another thing: a lot of people ask if using an outdoor spa is better than an indoor one, health-wise. Well, outdoor is better for ventilation, right? If you’re in a small indoor jacuzzi, the mist builds up, and you’re more likely to inhale those bacteria droplets. Outdoor spas have fresh air circulating, so that lowers the risk of Legionella and other airborne irritants. That’s a big plus—we always tell customers who are worried about air quality to go with outdoor, not indoor.
But let’s wrap this up without being too salesy, because the point is, outdoor spas can be super fun, great for relieving stress, hanging with friends, even gentle exercise (those jets are good for muscle soreness, trust me, I’ve had a bad back and used our demo spa to work it out). The health risks are real, but they’re totally manageable with the right maintenance, a little common sense, and a supplier who actually cares about you using the spa safely, not just selling it.

Just reach out, and we’ll walk you through whatever you need. No pressure, just good info.
Wait, let me make sure I didn’t miss any health risks. Oh! Maybe dehydration? If you’re in a spa for a long time, you sweat, right? Even if you don’t notice it, warm water makes your body lose fluids. So we tell people to bring a water bottle, especially if they’re staying in there for more than 30 minutes. Dehydration can lead to dizziness, which adds to that slip risk we talked about. That’s another small, easy thing to remember.
And for people with diabetes? If you have low blood sugar, sitting in a hot spa can make that worse. I’ve had a customer with type 1 diabetes say he had a hypoglycemic episode after a long soak—so if you have diabetes, check your blood sugar before getting in, and keep a snack nearby. Again, not a reason to skip the spa, just something to be aware of.
All right, that’s the real tea. Outdoor spas aren’t dangerous, but they do have rules, same as anything else. The key is choosing a good model, keeping up with maintenance, and listening to your body.
