Best Hot Tub Features: Jets, Lighting, Controls & More

When you're looking at hot tubs, you're going to see a lot of marketing language. Luxury jets. Chromotherapy. WiFi-enabled. Premium seating. Waterfall aromatherapy.

Some of it matters. Some of it doesn't.

I've been selling hot tubs in Lexington for 50 years. I've tested them all. I can tell you which features will actually improve your experience and which ones are just ways to charge you more money. Let me walk you through the real ones.

Jet Systems: This Matters

The jets are the whole point. This is where you need to pay attention.

There are different types of jet systems. Directional jets hit you from the side. Clustered jets create a massage effect. Some systems have jets you can turn on and off individually. Some let you adjust the pressure.

An American Whirlpool commercial-grade jet system is engineered differently than consumer models. The pumps are bigger. The jet action is more targeted. A 6-person American Whirlpool doesn't have the same power as some 8-person spas from other brands, but the water flow is optimized to hit the exact places your body hurts.

Vita Spa models come with advanced jet technology that rivals systems you'd find in spas costing twice as much. The jets are positioned to target your lower back, mid-back, shoulders, neck. You get that targeted therapy instead of just bubbles.

Here's what matters: does the spa have jets that address your specific pain points? Lower back pain? You need jets positioned on your lumbar. Shoulder tension? You need jets at shoulder height. Sore feet? Some models have foot jets.

Count matters somewhat. A 40-jet system sounds better than a 20-jet system, but if those 40 jets are shallow surface jets doing nothing, they're worthless. Better to have 16 well-placed, high-flow jets doing real work.

You sit in the spa before you buy it. Feel where the jets hit. Ask yourself if that's where your body hurts.

LED Lighting and Waterfalls: Nice to Have, Not Essential

Most spas now come with LED lighting under the rim. You can change the color. Blue, green, purple, whatever. It looks nice. It adds ambiance. It's aesthetic.

Does it improve the spa experience? No. You're not there to look at the color of the water. You're there because your back hurts.

That said, lighting is nice on winter nights in Lexington when you're out there in the dark. It makes the spa feel more inviting. And LEDs use virtually no electricity, so it's not costing you anything to run them.

Waterfalls fall in the same category. A waterfall spillway from the spa into a deck or basin looks beautiful. It's relaxing to hear. Some people love it. But it's not essential, and it adds cost and maintenance.

If you're choosing between a model with a waterfall and a model with better jet placement and you've got limited budget, pick the jets. You're not paying for the waterfall every time you use it. You are paying for the jets.

Digital Controls and WiFi: Worth It

This one's becoming standard, and it's actually useful.

A digital control panel lets you see your water temperature, adjust the jets, control the pump speed, set filtration cycles. You're not guessing. You're not fumbling around trying to find the temperature dial.

WiFi and app control is where it gets practical. You're home from work. It's 5 PM. You know you want to use the spa at 6. You open your phone, tap the app, and the heater starts warming up the water. You get home and the spa's ready to go.

In winter, this saves electricity. You heat the water only when you're going to use it instead of keeping it warm 24/7.

Some spas will let you control multiple settings from the app: turn jets on and off, adjust temperature, control lighting. It's convenient. You're not running in and out of the house to adjust things.

Is it essential? No. But if you're spending $5,000 or more on a spa, $300 to $400 for WiFi control is worth it.

Insulation and Cover Quality: Critical

This is where people mess up. They focus on jets and lighting and ignore insulation.

Full-foam insulation in the cabinet and underside means heat stays in the water. You're running the heater less. Your monthly electricity bill is lower. American Whirlpool builds with full-foam. That's standard. You're not paying extra for it, but you're getting it.

The cover is equally important. A cheap, thin cover doesn't insulate. A quality cover, like the ones that come with American Whirlpool and premium Vita Spa models, has high-density foam. It seals tight. Heat doesn't escape.

A $300 cover difference between models might cost you $15 to $20 a month in wasted heating if the cheap one isn't insulating. That pays for itself in less than a year.

If you're comparing two spas and one has better insulation and a better cover, that's worth more than an extra 10 jets.

Filtration Systems: Important

The filter cleans your water. You need it working. Most modern spas have cartridge filters that filter down to 20 microns. That's clean water.

Some systems have dual filters. One filters continuously, and you can switch to a second filter without shutting down. That's nice for maintenance, but not essential.

What you want is a filter that's easy to access, easy to clean, and easy to replace. If you have to drain the spa every time you change a filter, that's annoying. If the cartridge is $80 and you need to replace it monthly, that's expensive. Good spas have accessible filters and cartridges that last 2 to 3 months.

American Whirlpool and Vita Spa both have well-designed filtration. Easy access. Standard cartridges you can buy anywhere. That's what you're paying for.

Ergonomic Seating Design: Matters More Than You'd Think

How the seats are contoured affects how you feel in the spa.

Some spas have flat benches. You sit upright. That's not therapy, that's a hot water bench.

Good spas have contoured seats with headrests. Your neck and back support. Your body settles into the seat naturally. You're not fighting the design. The jets hit you correctly because you're positioned right.

Lounge seats in some models let you recline. Your legs are up, your back is reclined. The jets can target your entire back, not just your lower spine.

Sit in the spa before you buy. If the seat doesn't feel right, the rest of the spa doesn't matter. You'll get out uncomfortable.

Hot Tub Gimmicks to Ignore

Aromatherapy: Some spas have little aromatherapy oil dispensers. They smell nice for about five minutes. Not worth the cost.

Entertainment systems: Some spas have Bluetooth speakers built in. You can play music. Nice, but not essential. You can bring a waterproof speaker for a fraction of the cost.

Ozone generators: Some spas claim ozone reduces chemical needs. Maybe slightly. Not a game changer. You're still using chemicals.

Saltwater conversion: Some spas can be converted to saltwater. Salt systems generate chlorine. It's gentler on skin. But it costs more upfront and adds maintenance complexity. Standard chemicals work fine.

What You Actually Need

1. Jets positioned to address your pain points. That's the priority.
2. Full insulation to keep operating costs down. Don't skip this.
3. Quality cover. Easy maintenance, good heat retention.
4. Digital controls. Modern and practical.
5. WiFi app control if you want it. Convenient.
6. Ergonomic seating that fits your body. You're going to sit in this thing 500 hours a year. Make it comfortable.

That's it. Those features combined will cost you between $5,000 and $7,500 for a solid 4 to 6-person spa. American Whirlpool or Vita Spa at those price points includes all of those.

You don't need 60 jets. You need the right jets. You don't need a waterfall. You need good insulation. You don't need aromatherapy. You need a comfortable seat that supports your back.

Come sit in an American Whirlpool or a Vita Spa. Feel where the jets hit. Try the seat. See if the digital controls make sense. Ask me about the insulation and the cover quality. Those are the things that determine whether you actually use the spa for 10 years or you're frustrated with it by year two.
