Every detail engineered for therapeutic performance.

Six features you won't find combined in any other tub — designed alongside 48 doctors for daily use.

Balboa Smart Control System

While competitors rely on basic button controls, we've equipped our spas with the industry-leading Balboa Smart Control System — giving you precise, intelligent command over temperature, jets, and overall performance.

Balboa Smart Control System

High-Flow Circulation & Water Power

Most spas can't maintain strong, even pressure across every jet. Ours can. Our high-flow pump system is built to push consistent, high-pressure water across every jet, every time — so every seat delivers the same powerful massage.

High Flow Hydrotherapy System

Deep Ergonomic Seating Design

Our contoured seats are precision-designed to support your body's natural curves, ensuring every jet hits exactly where it needs to. Built for comfort during long sessions, whether hot or cold, every seat feels like it was made specifically for you.

Balboa Smart Control System

Targeted Foot Massage Jet

Your feet carry you through everything — they deserve the same attention as the rest of your body. While most spas ignore them completely, our dedicated foot jet delivers a continuous soothing massage that relieves tired, aching feet so you can soak in the relaxation.

High Flow Hydrotherapy System

Clean, High-Performance Water Filtration

Constant water maintenance is one of the biggest frustrations of owning a spa — draining your time as much as your energy. Our advanced filtration system handles it all for you, running continuous circulation and purification to keep your water crystal clear and fresh day after day, so your spa is always ready when you are.

Balboa Smart Control System

Premium-Grade Build & Finish

A spa should look just as good in five years as it does on day one. That's why every detail of ours is crafted with premium-grade materials built to withstand daily use, resist wear, and maintain a clean, modern finish that keeps your space looking sharp for the long haul.

High Flow Hydrotherapy System

Interior Chromatherapy Lighting

Most spas stop at a single basic light. Ours goes further. Our premium interior chromatherapy lighting creates the perfect ambiance for any mood, bathing your spa in rich, vibrant color that enhances the entire experience and sets ours apart from anything else on the market.

*Based on published research on hydrotherapy, heat exposure, and cold-water immersion. Results may vary.

The science is overwhelming.

The results are life-changing.

Every benefit below is drawn from published, peer-reviewed medical studies. This isn't marketing — it's decades of documented science.

+530%

Norepinephrine & Focus Surge

Cold water immersion at 57.2°F increases plasma norepinephrine by 530% — the neurotransmitter responsible for alertness, attention, and focus. The effect begins within minutes and lasts for hours after stepping out.

Srámek et al. · Journal of Applied Physiology · 2000 · head-out cold water immersion study

59%

Depression Symptom Reduction

59% of regular cold water immersion users reported a significant reduction in depressive symptoms. A brain fMRI study confirmed CWI shifts the positive-to- negative affect ratio from 1.75 to 3.0 — the threshold of psychological flourishing.

Yankouskaya et al. · Biological Psychiatry · 2023 · brain fMRI study (PMC9953392)

+40%

Brown Fat & Metabolic Rate

Cold exposure activates brown adipose tissue (BAT), increasing metabolic rate and improving glucose regulation. Your body burns calories generating heat — and the thermogenic effect continues for hours after each cold session.

Hanssen et al. · Journal of Clinical Investigation · brown adipose tissue activation

+250%

Dopamine — Lasting for Hours

Cold water immersion increases dopamine levels by 250% — and unlike the brief spike from stimulants, the elevation persists for hours. Better motivation, mood, and drive, triggered naturally by your tub every session.

Srámek et al. · J Applied Physiology · 2000 · plasma catecholamine response to cold immersion

+36%

Faster Sleep Onset

Hot water immersion 1–2 hours before bed accelerates sleep onset by 36% and significantly improves slow- wave deep sleep. The mechanism — core temperature drop triggering the brain's sleep signal — is one of the most reliable biological switches known to medicine.

Haghayegh et al. · Sleep Medicine Reviews · 2019 · 17-study systematic review

30–40%

Arthritis & Joint Pain Relief

Hot water reduces joint stiffness by 30–40% in arthritis patients. The Arthritis Foundation officially recommends hydrotherapy as a first-line treatment. Warm water buoyancy reduces joint loading by up to 90% compared to land-based therapy.

DEEP – DIVE THE RESEARCH

Decades of science.

Engineered into one tub.

Benefit #1 — Hot Mode

Cardiovascular Health & Longevity

The most comprehensive long-term research on passive heat therapy comes from Finland. In a landmark 20.7-year study published in JAMA Internal Medicine, researchers followed 2,315 middle-aged men and found a clear dose-dependent relationship: the more often they used heat therapy, the longer they lived.

A 2025 systematic review confirmed hot water immersion reduces systolic blood pressure by 6–7 mmHg for a full 24 hours after a single session. A 10 mmHg reduction is associated with a 20% reduction in major cardiovascular events.

  • Reduces arterial stiffness — a key marker of cardiovascular aging
  • Improves endothelial function comparable to exercise training
  • After 8 weeks, cardiovascular improvements matched those of sedentary adults who began an exercise program
  • Associated with 65% lower risk of Alzheimer's disease and 66% lower risk of dementia over a 20-year Finnish cohort
  • Reduces CRP — the primary circulating inflammation marker
BENEFIT #2 — COLD MODE

Mental Health & Mood Elevation

Cold water immersion triggers one of the most powerful neurochemical responses available without medication. Within minutes, the brain floods the body with norepinephrine and dopamine — the neurotransmitters at the center of attention, motivation, and mood.These elevations last for hours after you step out of the water.

A 2023 fMRI study demonstrated that cold water immersion shifts the brain's positive-to-negative affect ratio from 1.75 to 3.0 — crossing the threshold associated with psychological flourishing. Regular users show sustained reductions in depressive symptoms, anxiety, and chronic stress.

  • 530% increase in norepinephrine — sharper focus and mental clarity for hours
  • 250% increase in dopamine — sustained motivation and mood elevation
  • Brain fMRI data confirms structural changes in emotional regulation after regular cold immersion
  • 59% of regular users report meaningful reduction in depressive symptoms
  • Used by elite athletes and military personnel as a core mental performance tool
Benefit #3 — Hot Mode

Sleep Quality & Recovery

Hot water immersion in the evening is one of the most evidence-backed sleep interventions available. When your body exits warm water, your core temperature drops — sending a powerful biological signal to initiate sleep. Sleep researchers call this the "warm bath effect."

A 2019 systematic review of 17 studies found that a warm bath 1–2 hours before bed at 104 - 107.6°F for just 10 minutes significantly improved sleep onset, sleep quality, and slow-wave deep sleep — by accelerating the natural nocturnal drop in core body temperature.

  • Accelerates sleep onset — falling asleep up to 36% faster in clinical trials
  • Increases slow-wave (deep) sleep duration — the most restorative sleep stage
  • Reduces nighttime waking and improves overall sleep efficiency
  • Reduces cortisol levels — promoting calm before bed
  • Hydrotherapy jets relax muscle tension — removing physical barriers to sleep
  • Regular use associated with reversal of insomnia symptoms in multiple studies

Here is The Math

Why the Hot Spring 7™ is the best value in the lineup: At $24,999 for 7 seats it costs just $3,571 per person — the lowest per-person price of any model.

The Hot Spring 2 at $10,299 costs $5,150 per person and includes none of these. If three or more people will use it — the 7 is the obvious choice.

THE INVESTMENT CASE

$25,999 is the smart choice.

Most people who want year-round contrast therapy end up spending far more trying to piece together a solution that still doesn't match what the Icy Hot Spring 7™ delivers.

Premium 7-person hot tub (other brand) $12,000–$22,000
Medical cold plunge unit (separate) $8,000–$15,000
Dual electrical installations (220V × 2) $2,000–$4,000
Delivery (two units) $1,000–$3,000
5 years of spa memberships $6,000–$12,000
5 years of energy bills (running both units) $5,000–$10,000
5 years of chemicals, filters & cover replacements $2,000–$5,000
Separate maintenance on two units (5 yrs) $2,500–$7,500
Repairs & service calls over 5 years $1,500–$3,000
Total combined approach $40,000–$75,000+
Icy Hot Spring 7™ — all-in-one $24,999
You Save
Up to $50,000
vs. piecing it together separately

PER-PERSON VALUE

Seven People. One Investment.

$24,999 across 7 family members used 3× per week for 10 years works out to less than $0.50 per person, per session — for access to the world's most advanced home wellness spa. No gym membership, no spa club, no cold plunge membership comes close to that value.

HEALTH ROI

The Cost of Not Having It

One chronic health event — a cardiac episode, a series of physical therapy visits,ongoing sleep medication — can easily cost $10,000 $50,000. The Icy Hot Spring 7™ is preventive medicine. The peer-reviewed studies above show it works. This is the investment that pays you back

HSA / FSA ELIGIBLE

Tax-Advantaged Purchase

Because the Icy Hot Spring 7™ is designed for documented medical and therapeutic purposes, many customers use HSA or FSA funds toward their purchase. Call us for supporting documentation. 0% APR financing available — most approvals are same day.

HOW THE ICY HOT SPRING 7™ WORKS

Two powerful therapies. One extraordinary tub.

Tap to feel the difference
Hot Mode

104°F

Therapeutic heat • deep muscle relaxation • detoxification

The Icy Hot Spring 7™ operates in two distinct therapeutic modes — Hot Mode
and Cold Mode. Switch anytime from the touchscreen. Most families use Cold Mode
from May through September and Hot Mode from October through April.
PERFECT FOR FALL & WINTER

Hot Mode

80°F – 1d4°F · 100 Hydrotherapy Jets Active

Set the Icy Hot Spring 7™ to Hot Mode and experience a full-body clinical-grade hydrotherapy session. The 100 precision jets target every major muscle group while heat therapy activates your cardiovascular and recovery systems.

  • Precise temperature control from 80° to 104°F
  • 100 active hydrotherapy jets for full-body massage
  • All 7 seats fully functional with targeted jets
  • 40% lower all-cause mortality with 4–7x/week use
PERFECT FOR SPRING & SUMMER

Cold Mode

50°F – 72°F (10°C – 22°C) · All 7 Seats Available

In summer, switch to Cold Mode and enjoy therapeutic cold water immersion — what elite athletes and longevity researchers call the single most powerful recovery tool available.No ice required. No separate unit. Just set the temperature and step in.

  • Integrated chilling system — no ice bags needed
  • Cools to 50°F and maintains temperature precisely
  • All 7 seats available for cold immersion simultaneously
  • UV + Ozone filtration keeps cold water crystal clean
How modes work: Hot and Cold modes are not used simultaneously — the tub operates in one mode at a time. This is how you get maximum therapeutic benefit from each temperature. Switch seasonally (cold in summer, hot in winter) or any time you want a change — there is no restriction on how often you switch. Hot-to-cold in a single session is not supported because each mode requires all 470 gallons to reach a stable therapeutic temperature.
Life before. Life after.

WITHOUT THE ICY HOT SPRING 7™

  • Hot tub unused 6 months a year Paying electricity to maintain a tub nobody touches insummer
  • Cold plunge for one person Your family waits outside. The ritual never happens together.
  • $450/month on wellness memberships Cryo clinics, spa clubs, physical therapy — costs that never end
  • Poor sleep, stiff joints, high stress No consistent recovery practice means compounding health debt
  • Seasonal health Hot therapy in winter. No therapy in summer. Half a year wasted.
  • Wellness is a solo activity Nobody does it together. The habit never sticks.

REAL, UNCENSORED, UNEDITED REVIEWS
To help you decide for yourself how effective Medical Hot Springs are, we have listed real, uncensored reviews, emails and comments from customers who have paid for and used them.
★★★★★
"As a cardiologist, I read every study on heat and cold therapy before I bought one. Fourteen months in, my resting heart rate is down, my sleep tracker numbers are way up, and I genuinely look forward to my evening contrast session. I've started recommending it to my own patients."
Dr. James W.
Houston, TX · Owner for 14 months
★★★★★
"We were paying for two spa memberships, a separate cold plunge club, and weekly PT. The Icy Hot Spring 7 replaced all of it inside the first month. The kids fight over who gets the next session and my husband finally stopped complaining about his back. Best single purchase we've made for the house."
Linda M.
Park City, UT · Owner for 8 months
★★★★★
"I have rheumatoid arthritis. Hot mode cuts my morning stiffness in half, and a cold session after a bad flare-up is honestly life-changing. Knocking off one star because the 220V install took longer than the install guy expected — but once it was running, zero regrets."
Robert P.
Seattle, WA · Owner for 11 months
★★★★★
"I used to drive 35 minutes each way to a cold plunge studio three times a week. Now I roll out of bed and step into mine. Recovery from leg day is at least 30% faster, and I'm sleeping through the night for the first time in years. Honestly wish I'd bought it the day it came out."
Lisa E.
Austin, TX · Owner for 6 months
★★★★★
Started having brutal night sweats and broken sleep after 50. Hot mode three evenings a week, cold on weekends — my sleep is finally back. Four stars only because the cover is heavier than I'd like and switching modes takes about a day to fully stabilize. Results made me a believer anyway."
Priscilla R.
Phoenix, AZ · Owner for 9 months
★★★★★
"We're both in our late 60s and our knees and shoulders had kept us out of the community pool for two years. The Hot Spring 7 changed our routine completely — 20 minutes together every evening, hot mode in winter, cold in summer. It's become our favorite hour of the day."

Frequently Asked Questions
ABOUT THE PRODUCT
Can I switch between hot and cold in the same session?
Yes — you set the temperature anywhere from 50°F to 104°F. Small changes happen quickly. A full swap from hot soak to ice plunge takes 1–2 days for the water to fully change over. Most owners pick a mode per day or per season: hot one day, cold the next, or cold all summer, hot all winter.
How long should I stay in each mode?
Hot: 15–30 minutes is the typical session. Cold: start with just 1–3 minutes and build up — 5 minutes is plenty for most people, with 10 minutes as the upper limit for experienced users. Always listen to your body and consult your doctor first if you have cardiovascular conditions.
What does the science say about cold water immersion?
Cold water immersion has been studied for its effects on mood, alertness, and post-exercise recovery. Many regular users describe feeling more energized after a cold plunge, with better sleep and faster recovery from workouts. Individual results vary, and cold immersion is a tool used by athletes worldwide.
How often should I use each mode?
Most healthy adults enjoy hot soaks several times a week and shorter cold sessions a few times a week. Find a rhythm that works for your body — many owners hot soak in the evening to wind down, and cold plunge a few times a week for a recovery boost. Always check with your doctor about what's right for you.
PURCHASE, DELIVERY & INSTALLATION
How much does it cost to run each month?
Comparable to running a refrigerator. Heavy-duty insulation and our high-efficiency cover keep energy draw low. Most owners see only a small bump on their monthly electric bill.
How long until I can use it after delivery?
Most owners are soaking within 48 hours of delivery — that covers filling, heating, and balancing the water. Cold mode takes a little longer on its first chill-down, but once it's there, you're set.
What does the 5-year warranty cover?
Our 5-year tiered warranty is one of the strongest in the industry: 5 years structure, 3 years parts, 1 year labor. If anything goes wrong, we send a certified technician to your home — you ship nothing, lift nothing. Most claims resolved within 2 weeks.
What kind of base does it need?
A flat, level surface that holds about 5,000 lbs when filled — a reinforced deck, concrete pad, or compacted gravel all work great. We'll walk you through the right setup for your space before delivery. No surprises on the day.
ELECTRICAL & POWER
What are the electrical requirements?
The Icy Hot Spring 7™ runs on a dedicated 240V / 60A circuit protected by a Class A GFCI breaker, installed by a licensed electrician. We send you the full electrical specs as soon as you order so your electrician can prep before delivery day.
Do I need GFCI protection for both 240V and 120V?
Yes — both. The main 240V service needs a Class A GFCI breaker, and the internal 120V heat pump system needs its own GFCI protection not exceeding 5mA. Your electrician will handle both as part of a code-compliant install.
What wiring needs to be run from my house?
One main 4-wire cable — Black, Red, White, Green — in minimum 6 AWG copper rated for 90°C. The white (neutral) wire is mandatory: even though the tub runs on 240V, the neutral powers internal 120V components like the heat pump, ozonizer, and circulation pump.
Do I need a second line for the heat pump?
No. The 120V heat pump connects directly to the tub's internal control box (Port J33). Everything runs off the single 240V cable you already installed — no second line from your house panel needed. Saves you time and installation cost.
Where does the GFCI disconnect get installed?
Per National Electric Code: within sight of the tub and at least 5 feet from the spa walls. Your electrician will install it in your main house panel or a dedicated sub-panel.
For your electrician — technical details
Key install specs to hand to your electrician:
  • Torque: Main terminal block (TB1) to 27–30 in. lbs.
  • Access: Remove the cabinet panel opposite the spaTouch 3 screen to reach the Balboa control box
  • Conduit entry: 26mm hole at the bottom of the corner skirt panel closest to the box
  • Bonding: Use the external bonding lug with #8 AWG solid copper to the spa's common bonding grid
  • HiPot testing: Disconnect the slip terminal (green wires) from Port J11 before testing — reconnect after
  • Power shedding: The 5.5kW heater auto-disables when 2+ high-speed massage pumps run, keeping draw within the 60A breaker limit
HEALTH, SAFETY & MAINTENANCE
Is it safe for people with health conditions?
Hot tubs are safe for many healthy adults. If you have any medical condition — heart issues, high or low blood pressure, diabetes, pregnancy, or take any prescription medication — please consult your doctor before using it. We also strongly recommend never using the tub alone if you have a medical condition; always have someone nearby to supervise.
Can it be used outdoors year-round in cold climates?
Yes — it's built to be outdoor. Heavy insulation, freeze-protection sensors, and our high-efficiency cover keep it running smoothly through every season. If you'll be away during a hard freeze, see our winterizing note below.
What water care does it need?
Simple. Test strips, sanitizer as needed, and a full drain every few months. How much care it needs depends on how often you use it. We include a starter kit and a step-by-step guide so you'll know exactly what to do.
Is it safe for kids and family use?
Built for the whole family. The water heats up to a maximum of 104°F — for children we recommend a lower setting and shorter sessions. Children must be supervised by an adult at all times — no exceptions. With basic safety in place, your hot tub becomes the favorite hangout in the house.
How much maintenance does a hot tub need?
Very little. A quick filter rinse, a deeper clean every so often, and a full drain every few months is usually all it takes. Most owners are surprised how easy it is to keep their tub ready to enjoy.
How do I winterize it if I go away?
We recommend draining the system. It's easy to do, and we'll walk you through every step.
