Description

Heat + Cold Recovery System

Two Therapies. One Protocol. The Most Complete At-Home Recovery Setup Available.

Separately, the SaunaBox® SmartSteam and the PlungeBox XL are each effective recovery tools. Together, they form something more powerful — a contrast therapy protocol that alternates deliberate heat exposure with deliberate cold exposure in a single session. The Recovery Bundle XL gives you both, bundled at a meaningful saving over purchasing each individually. With over 1,800 five-star reviews across the SaunaBox product line, it's a combination that's earned its reputation.

The science behind contrast therapy is well-established. Heat exposure — the SaunaBox reaches 115–120°F with near-100% steam humidity — triggers cardiovascular responses, relaxes muscle tissue, and drives deep circulation. Following immediately with cold immersion in the PlungeBox XL causes vasoconstriction, reduces inflammation, increases norepinephrine, and activates the body's thermogenic response. The alternation between the two states creates physiological adaptation that neither modality produces alone: improved resilience, faster recovery, improved sleep architecture, and a natural adrenaline and mood lift that typically lasts hours.

The Bundle XL pairs specifically the SmartSteam portable steam sauna — fully set up in 5–10 minutes — with the PlungeBox XL lay-flat cold tub, which at 48.4" long accommodates users up to 6'6" for complete full-body cold immersion. No permanent installation, no renovation. Both set up anywhere in your home, backyard, garage, or patio.

The Science of Contrast Therapy

What Happens When You Alternate Heat and Cold

Contrast therapy — also called hot-cold cycling or Nordic bathing — has been studied extensively in sports science and sports medicine. The physiological mechanisms are distinct from either modality used alone.

♨️

Steam Heat Session

10–20 min at 115–120°F

Vasodilation · Deep muscle relaxation · Elevated heart rate · Cortisol reduction

Transition

🧊

Cold Plunge

3–5 min in cold water

Vasoconstriction · Norepinephrine surge · Inflammation reduction · Metabolic activation

🔄

Cardiovascular Pumping Effect

The alternation between heat-induced vasodilation and cold-induced vasoconstriction creates a pumping effect on the cardiovascular system. Blood vessels expand and contract in sequence, improving peripheral circulation and accelerating the clearance of metabolic waste products from muscle tissue — including lactate and inflammatory cytokines.

🧠

Neurochemical Response

Cold water immersion following heat causes a significant norepinephrine release — up to 300% above baseline in some studies. This neurochemical response is behind the characteristic mood lift, mental clarity, and energy boost that contrast therapy practitioners report. The effect is distinct from either heat or cold used in isolation.

💪

Muscle Recovery Acceleration

The combination addresses muscle recovery from two directions simultaneously: heat relaxes and lengthens muscle tissue while driving nutrient-rich blood flow; cold reduces post-exercise inflammation and edema. Athletes using contrast therapy protocols consistently report reduced DOMS (delayed onset muscle soreness) compared to passive recovery.

🔥

Brown Fat Activation

Repeated cold exposure activates brown adipose tissue (brown fat), which burns calories to generate heat. Unlike white fat, which stores energy, brown fat is metabolically active. Regular cold exposure — particularly following heat — increases brown fat mass and activity, supporting metabolic function and thermogenesis independent of physical training.

🔥 The Heat Side

SaunaBox® SmartSteam — Your Portable Steam Sanctuary

The SaunaBox® SmartSteam is the steam sauna half of this bundle — a portable, app-enabled steam system that sets up in 5–10 minutes wherever you need it. Pour distilled water into the SmartSteam chamber and within 10 minutes, steam flows into the insulated tent at 115–120°F with near-100% humidity. The high humidity environment makes steam heat significantly more intense than equivalent dry heat — the moisture carries heat energy directly to your skin and deep muscle tissue in a way dry air cannot replicate.

PlungeBox XL lay-flat cold plunge tub showing 48-inch oval shape for full-body cold immersion

🧊 The Cold Side

PlungeBox XL Lay-Flat — Full-Body Cold Immersion

The PlungeBox XL is the cold plunge half of this bundle — a 500-liter oval lay-flat tub that at 48.4" long accommodates users up to 6'6" in complete full-body submersion, lying flat rather than seated. Standard barrel-style cold plunge tubs leave taller users with their legs above the waterline. The XL's lay-flat design means everything from shoulders to feet is submerged simultaneously — which is the point of cold immersion. Fill with water and ice and you're ready in minutes. Extra thick insulation retains cold temperature longer between ice additions.

Dimensions 48.4" × 31.1" × 29.5"

Capacity 500 liters

Fits Up to 6'6" / 350 lbs

Tub Weight 5.7 kg empty

Oval lay-flat design — full-body submersion from shoulders to feet

Setup Guide

Both Ready in Under 30 Minutes. Total.

The SaunaBox sets up in 5–10 minutes and is steam-ready in 10 more. The PlungeBox XL inflates, fills, and ices in about 15 minutes. Run them in parallel and your first contrast therapy session is within the hour.

Assemble Frame + ThermoShield Cover

Connect the fiberglass frame sections and fit the ThermoShield cover over it. Takes about 5–10 minutes first time.

Fill SmartSteam® with Distilled Water

Pour distilled or purified water into the SmartSteam chamber — not tap water, which causes mineral buildup over time.

Power On + Wait 10 Minutes

Turn on via the SmartSteam unit or the SaunaBox® app. Steam begins flowing into the tent within 10 minutes.

Set Duration + Step In

Place the portable chair and SweatLock mat, zip the flap, and begin your heat session. 10–20 minutes is typical for contrast therapy protocols.

Inflate with Hand Pump

Use the included hand pump to inflate the oval tub walls to firm rigidity. Takes 5–10 minutes manually — no power source required.

Fill with Cold Water

Fill to your desired session depth via garden hose. At 500 liters, filling to immersion depth takes 10–20 minutes at typical household flow rates.

Add Ice + Wait for Temperature

Add ice and wait 10–15 minutes for temperature to equalize. The XL's thick insulation helps maintain cold through your session.

Lie Flat + Submerge

Step in and lie back for full-body lay-flat immersion. 3–5 minutes is typical for contrast therapy. Cover the lid between sessions to retain cold.

Bundle Value

Why the Bundle Makes Sense

The Recovery Bundle XL gives you both modalities at a combined discount — plus the option to add a chiller later when you're ready for ice-free cold plunging.

💰

Bundle Savings

Purchasing the SaunaBox SmartSteam and PlungeBox XL as a bundle saves meaningfully versus buying each product separately. Both items ship together in a single order — one delivery, one setup session, one complete recovery system.

🔌

Upgrade to Ice-Free Later

The PlungeBox XL is compatible with the PlungeBox 1/2HP Water Chiller Pro. When you're ready to eliminate ice management, add the chiller — it connects directly to the XL for continuous temperature control down to 35°F with built-in filtration and ozone sanitation.

Common Questions

Frequently Asked Questions

Answers to the questions most commonly asked about the Recovery Bundle XL and contrast therapy protocols.

Contrast therapy is the deliberate alternation between heat and cold exposure in a single protocol. Heat causes vasodilation — blood vessels expand, circulation increases, muscle tissue relaxes. Cold causes vasoconstriction — vessels contract, inflammation decreases, norepinephrine surges. The alternation creates a cardiovascular pumping effect that accelerates clearance of metabolic waste from muscles, while the cold-induced norepinephrine response produces the mood and energy lift that contrast therapy practitioners report. The effects are distinct from either modality used alone.

A common starting protocol is 10–20 minutes in the SaunaBox steam sauna followed by 3–5 minutes in the PlungeBox cold plunge. This cycle can be repeated 2–3 times in a single session for more advanced practitioners. The key is transitioning between hot and cold relatively quickly — within 1–2 minutes — to maximize the vascular response. Always consult a healthcare professional before beginning contrast therapy, especially if you have cardiovascular conditions.

The SaunaBox SmartSteam included in this bundle reaches 115–120°F with near-100% humidity. Because water carries heat energy more efficiently than dry air, the steam environment at 115–120°F produces physiological effects comparable to a dry sauna running significantly higher — elevated heart rate, deep sweating, and full cardiovascular stress. For most people, this temperature range is actually more intense than it sounds.

The PlungeBox XL's lay-flat design at 48.4" long accommodates users up to 6'6" in complete full-body submersion. For contrast therapy to be most effective, maximizing the body surface area in cold water matters — the more skin exposed to cold simultaneously, the stronger the physiological response. Standard barrel-style tubs seat users upright with legs partially above the waterline. The XL Lay-Flat puts your entire body — including your legs and hips, which are the largest muscle groups — into the cold simultaneously.

No — contrast therapy protocols use the modalities sequentially, not simultaneously. The SaunaBox and PlungeBox are used in alternation: steam session, then cold plunge, then optionally repeat. Both can be set up and ready in their respective states at the same time, making the transition between them quick and convenient. Having both set up and ready is the practical advantage of owning the bundle — you don't have to prepare one while the other is running.

SaunaBox: After each session, leave the door flap open to air out and wipe down interior condensation. The SweatLock Floor Mat is machine washable. The anti-microbial interior handles hygiene passively between sessions. PlungeBox XL: Change the water every two weeks based on use frequency. Between changes, wipe down the interior with a natural cleaning spray and rinse. The insulated cover lid keeps debris out and helps maintain temperature between sessions.

Yes — the PlungeBox XL is compatible with the PlungeBox 1/2HP Water Chiller Pro, which is available separately. The chiller connects via the tub's hose port and provides continuous temperature control down to 35°F with built-in 20-micron filtration and ozone sanitation. This eliminates ice purchasing and management entirely. The chiller's hose set is included with the chiller purchase — no additional adapters required for the XL tub.

The Recovery Bundle XL may qualify for HSA/FSA purchase through Truemed for customers with qualifying medical conditions. Both steam therapy and cold water immersion therapy have documented medical and rehabilitative applications — including post-surgical recovery, chronic pain management, inflammation reduction, and sports medicine. Eligible customers typically save 25–35% using pre-tax health dollars. Eligibility is confirmed through Truemed's qualification process at checkout.

Both setups can run in parallel. The SaunaBox takes 5–10 minutes to assemble, then is steam-ready 10 minutes after powering on. The PlungeBox XL takes 5–10 minutes to inflate, then 10–20 minutes to fill and ice. Running both simultaneously, your first complete contrast therapy session can begin within 20–30 minutes of starting setup. After the first time, setup is significantly faster as you learn both systems.

Yes — the SaunaBox SmartSteam and PlungeBox XL are fully independent products that can be used on their own in any session. Many people use the steam sauna for evening relaxation without cold plunging, or use the cold plunge alone for post-workout recovery without heat. The bundle's value is in having both available for contrast therapy when your protocol calls for it, while not requiring you to use both every session.
