Everything you need to know before you buy.

Absolutely. Every project begins with your space, your goals, and your vision. We don't believe in one-size-fits-all solutions. Every wellness space is individually designed to complement your home's architecture while creating the best possible wellness experience. Our design team works closely with you to determine:

• Layout and flow
• Overall size and dimensions
• Materials and finishes
• Interior bench configurations
• Glass placement and privacy
• Lighting design
• Audio integration
• Heater selection
• Cold therapy options
• Storage and utility areas
• Architectural details

The result is a space that feels like it was always meant to be part of your home.

Most sauna companies sell a fixed catalog of models shipped from a warehouse. Cielo doesn't. Every project is designed around your specific property, then handcrafted and installed by our own team across the New York Tri-State Area, not dropped off as a flat-pack kit. That means the design accounts for your home's actual architecture, the region's real climate, and, for New York, New Jersey, and Connecticut specifically, the zoning and permit requirements that vary meaningfully from one town to the next. It's a more involved process than ordering a prefabricated unit, and it's why our clients' spaces tend to look and perform like part of the house rather than an accessory next to it.

Yes. Many of our projects are completed in collaboration with architects, interior designers, builders, landscape architects, and pool contractors. We provide design guidance, construction drawings, material specifications, and technical support throughout the project to ensure every detail integrates seamlessly with the rest of the home.

Yes. We design both indoor and outdoor wellness spaces. Whether you're converting a basement, garage, spare room, pool house, or creating a backyard wellness retreat, every project is engineered specifically for its environment. We consider ventilation, insulation, drainage, electrical requirements, finishes, and long-term durability from the very beginning of the design process.

Every project is built using premium materials selected for durability, performance, and timeless design. Depending on the project, materials may include:

• Clear Western Red Cedar
• Thermally modified wood
• Premium hardwoods
• Insulated tempered glass
• Architectural aluminum
• Natural stone
• Large-format porcelain
• Custom lighting and architectural finishes

Material selections are tailored to each project's style, performance requirements, and budget.

Yes. One of our biggest priorities is making your wellness space feel like a natural extension of your home. Whether your home is modern, transitional, contemporary, traditional, or rustic, we customize the architecture, materials, colors, and finishes to create a seamless look. The goal is for your wellness space to feel thoughtfully designed rather than simply added on.

No. While custom saunas are at the heart of many of our projects, our expertise extends to complete wellness environments. Many clients choose to combine multiple wellness experiences into one cohesive space, including cold plunges, steam rooms, showers, relaxation areas, fitness spaces, and custom storage. Our role is to design the entire experience, not just one product.

Yes. Every project begins with a professional design process. Depending on the project, this may include:

• Design consultation
• Site evaluation
• Floor plans
• 3D renderings
• Material selections
• Technical drawings
• Construction documentation

This ensures every detail is thoughtfully planned before fabrication begins, resulting in a smoother installation and a better finished project.

When you immerse in cold water (typically 45-59°F), your body activates a powerful chain of responses. Blood vessels constrict, pushing circulation to your vital organs. Norepinephrine surges, up to 300%, improving mood, focus, and stress resilience. After you exit, blood rushes back to the extremities, flushing metabolic waste from muscles. The result: faster recovery, reduced inflammation, and a calm, sustained energy that can last hours. With regular practice, your nervous system becomes measurably more resilient to stress.

Contrast therapy is the practice of alternating between heat exposure (sauna) and cold immersion (cold plunge) within the same session. The combination creates a "vascular pump" effect, your blood vessels rapidly dilate and constrict in response to temperature shifts, giving your cardiovascular system a workout that's hard to replicate any other way. The alternating hormonal cascade (heat triggers relaxation hormones; cold triggers alertness hormones) leaves you in an unusually balanced state: calm but focused. Most researchers and practitioners consider contrast therapy superior to either modality alone for recovery, mood, and metabolic health.

Frequency matters more than session length. Research suggests 3-4 sessions per week is the sweet spot for most people to experience measurable benefits in cardiovascular health, inflammation markers, and mental clarity. Daily use is safe for most healthy adults. A typical session, 15-20 minutes of sauna, 2-3 minutes of cold plunge, repeated 2-3 rounds, takes about 45-60 minutes total and fits naturally into a morning or evening routine.

The research here is compelling. Multiple large-scale studies (most prominently from the University of Eastern Finland) have found that regular sauna users have significantly lower all-cause mortality rates. The mechanisms include reduced cardiovascular stress, lower chronic inflammation, improved insulin sensitivity, and better sleep quality, all factors closely tied to biological aging. Heat stress also triggers heat shock proteins, which help repair cellular damage. This is why longevity-focused physicians like Andrew Huberman and Peter Attia consistently recommend sauna as one of the highest-ROI health habits available.

Yes, and this is one of the most underappreciated benefits. An evening sauna session raises your core body temperature significantly. When you exit, your temperature drops rapidly, and this drop signals to your brain that it's time to sleep, accelerating the transition into deep sleep. Cold therapy complements this by lowering cortisol and sympathetic nervous system activity. Many customers report falling asleep faster and waking up feeling more restored within just a few weeks of establishing a regular routine.

Yes. Sauna use at high temperatures triggers a significant release of beta-endorphins, the same neurochemicals released during intense exercise, creating what many describe as a "sauna high." Cold exposure causes a dramatic and sustained spike in norepinephrine and dopamine. Together, these neurochemical effects improve mood, reduce symptoms of anxiety and depression, and sharpen cognitive function. Some researchers are now investigating regular sauna use as a potential adjunct therapy for treatment-resistant depression.

Most people notice improved sleep and better mood within the first 1-2 weeks of consistent use. Recovery improvements (less muscle soreness, faster bounce-back after workouts) typically appear within 2-4 weeks. Longer-term cardiovascular and metabolic benefits build over months of consistent practice. The experience of owning your own system at home, where you can use it on your schedule, every day if you choose, dramatically accelerates the results compared to occasional visits to a spa or gym.

Not in the way most people hope. The weight you see drop immediately after a session is water loss from sweating, and it returns as soon as you rehydrate. It isn't fat loss. What sauna use does support is real: improved cardiovascular fitness, better circulation, and a growth hormone response, all genuinely linked to metabolic health over time. If weight loss is the goal, sauna use is a legitimate complement to diet and exercise, not a replacement for either.

No, and the difference matters more than it might seem. A sauna blanket wraps a heating element around your body and raises your skin temperature directly, while a real sauna raises the temperature of the air and surfaces around you, closer to the full-body, ambient heat exposure the cardiovascular research is actually based on. A blanket is a reasonable low-cost entry point, but it doesn't replicate the same depth of heat exposure, the dedicated space, or the ability to pair immediately with a cold plunge in the same room.

With a properly engineered system, yes. Cielo's builds use the Cielo Smart Sauna System to control temperature, humidity, and lighting from a single interface, so a session can be started before you even walk into the room. This is a real, growing expectation for a home wellness space in 2026, not a gimmick: consistent heat and humidity control is part of what makes the space perform correctly session after session.

Both are legitimate, and the right answer depends on the effect you're after. Morning sessions tend to leave people alert and focused, especially when finished on cold exposure, which triggers a real norepinephrine response. Evening sessions are more associated with sleep benefits: the rapid drop in core body temperature after leaving the heat helps signal the body toward sleep. Many of our clients use their space differently depending on the day, which is part of why having it at home, rather than on a gym's schedule, actually matters.

This is a legitimate question to ask any provider, not just us. Electromagnetic field (EMF) output varies by heater design and manufacturer, and quality traditional and infrared heaters on the market today generally test at low levels, well below the thresholds health agencies flag as a concern. Ask any sauna provider for third-party EMF test data on the specific heater going into your build; a company confident in its equipment should have it readily available.

The rapid cardiovascular changes involved in contrast therapy, blood pressure rises in the heat, drops sharply in the cold, can be risky for people with uncontrolled hypertension. If your blood pressure is well-managed with medication and your doctor has cleared you for moderate exercise, sauna use may be appropriate with shorter session lengths and more gradual temperature transitions. Always get explicit clearance from your cardiologist or physician before starting.

Children can use saunas under adult supervision, but with significant modifications. Children's thermoregulation is less efficient than adults', meaning they overheat faster. We recommend limiting sessions to 5-10 minutes maximum at lower temperatures (around 140-160°F) for children over age 6. Cold plunges are generally not recommended for young children. Consult your pediatrician if you have any doubts about your child's readiness.

Exit the sauna or cold plunge immediately if you experience any of the following:

• Dizziness or lightheadedness
• Nausea
• Difficulty breathing
• Chest tightness or pain
• Sudden weakness or numbness
• Feeling of impending loss of consciousness

After exiting, rest in a cool area, hydrate, and if symptoms persist, seek medical attention. These signs are rare in healthy adults but should never be ignored.

A typical 20-minute sauna session at 185°F causes you to sweat out approximately 0.5-1 liter of fluid. We recommend drinking at least 16 oz of water before your session, having water accessible inside the sauna, and drinking 16-24 oz after you finish. Electrolyte supplementation is helpful for those doing multiple rounds or longer sessions. Avoid alcohol before or during sauna use, it significantly impairs your body's ability to regulate temperature.

No. Sauna use is contraindicated during pregnancy. Elevated core body temperature, especially in the first trimester, is associated with neural tube defects and other developmental complications. Cold plunges are similarly inadvisable during pregnancy. If you are nursing or recently postpartum, consult your OB/GYN before resuming.

People with Raynaud's (a condition causing excessive vasoconstriction in the extremities in response to cold) should approach cold plunge therapy with extreme caution and only under medical supervision. Even brief cold exposure can trigger severe arterial spasm in affected individuals. In most cases, we recommend against cold plunge use for people with moderate to severe Raynaud's.

Traditional Finnish saunas operate at 160-195°F. This range delivers the strongest cardiovascular and hormonal effects documented in the research. Infrared saunas operate at lower temperatures (120-150°F) and may require longer sessions (30-45 minutes) to achieve comparable benefits. Most experienced users settle into 175-190°F as their preferred temperature. Session duration of 15-20 minutes per round is the sweet spot for most people.

The research suggests that temperatures between 45-59°F (7-15°C) are effective for triggering the cold shock response and the associated hormonal and vascular benefits. Water below 45°F is unnecessarily harsh for most users and increases the risk of cold shock. If you're new to cold therapy, starting at 55-60°F and working down to your target temperature over several weeks is a smarter approach than jumping straight to the coldest setting.

Always sauna first. The standard contrast therapy sequence is: heat → cold → rest, repeated in rounds. Starting with heat opens up blood vessels and relaxes muscles, maximizing the contrast effect when you transition to cold. Ending on cold has the additional benefit of leaving you in a more alert, energized state, ideal for morning routines. If you prefer a more relaxed finish, end on 5-10 minutes of gentle heat or a few minutes of room-temperature rest.

Yes, and many performance athletes consider post-workout sauna one of the most effective recovery tools available. Sauna after exercise extends the cardiovascular load and enhances muscle recovery by increasing circulation and growth hormone release. If you're using cold plunge post-workout for immediate inflammation control, do the cold plunge first (within 30 minutes of training), then move to the sauna. Note: for strength training, some research suggests waiting 1-2 hours before sauna to avoid blunting the anabolic response to resistance exercise.

Most consumer electronics, including iPhones, Apple Watches, and Android devices, are not rated for temperatures above 113°F (45°C). Taking them into a 180°F sauna will likely permanently damage them. We recommend leaving devices outside and using the time as a deliberate digital detox, which, anecdotally, our customers say is one of the most valuable parts of the practice.

Most Cielo saunas require a dedicated 240V circuit. Depending on the heater size:

• Smaller units: 30-amp, 240V circuit
• Standard units: 40-50-amp, 240V circuit
• Larger custom configurations: up to 60-amp, 240V circuit

This work must be performed by a licensed electrician. Electrical work typically takes 2-4 hours and costs $300-$800 depending on run distance and local labor rates. In some New York counties (Westchester is a notable example), electricians also need a current county-level electrical license in addition to their New York State license, so it's worth confirming that specific credential if your property is in one of these areas.

Almost always, yes, and the specifics depend heavily on your exact town, not just your state. Electrical permits are essentially universal for any new 240V circuit, and your licensed electrician typically handles that filing. Structural and zoning requirements are where it gets genuinely local: two towns in the same county can have very different rules for where an accessory structure like a sauna can sit on your property. We research your specific municipality's requirements before finalizing a design, and Cielo actively assists with the permits connected to our own scope of work, coordinating directly with your local building department, and with an architect, engineer, or historic preservation commission where one is already involved in your project.

More than most homeowners expect. In New Jersey, the state's Uniform Construction Code is consistent everywhere, but zoning (setbacks, lot coverage, accessory structure size) is set town by town: a 100-foot accessory setback in one Bergen County town can be a 15-foot setback in the next one over. Some New Jersey towns with rockier or steeply sloped terrain also require an engineered drainage plan for any new construction, which isn't something every town asks for. In New York, if your property sits in a designated historic district (true for parts of Brooklyn and several older Westchester and Hudson Valley towns), a Landmarks Preservation Commission review can apply as a separate approval process from your standard building permit, not a substitute for it. Coastal New York properties can also fall under additional flood-zone or erosion-control requirements. Connecticut's municipal zoning varies by town in the same directional way New Jersey's does; we recommend confirming your specific town's accessory-structure rules directly with its building department. For a deeper look at how this plays out town by town, see our guide to navigating municipal permits and zoning for custom outdoor spaces.

The transition time between your sauna and cold plunge directly impacts the physiological effect, the shorter the transition, the more dramatic the vascular response. We recommend positioning your cold plunge within 10-15 feet of your sauna. Ideally, they're adjacent, with only a towel rack or outdoor shower between them. Avoid designs where the transition requires going through a door, up stairs, or across a long stretch of exposed yard in cold weather.

For a typical 2-person sauna and cold plunge system:

• Foundation prep (if needed): 1-3 days (depending on concrete curing time)
• Sauna assembly: 2-4 hours (for two adults)
• Electrical installation: 2-4 hours (licensed electrician)
• Cold plunge setup: 1-2 hours

Most customers are using their system within 3-7 days of delivery, with the majority of that time being foundation or electrical scheduling.

Cielo saunas are built for year-round outdoor use across all U.S. climate zones, including harsh winters, high heat and humidity, and coastal salt air. Our materials are selected specifically for outdoor durability: pressure-treated structural members, marine-grade hardware, insulated tempered glass, and exterior-grade cedar or thermally modified wood that resists moisture, UV, and insects. We've installed systems in Minnesota winters and South Florida humidity with equal success.

Our saunas ship via LTL freight on a pallet. Delivery is curbside, meaning the freight carrier brings the unit to the edge of your driveway or street. For most configurations, moving components to your installation site requires 2-3 people and a hand truck or dolly. If you require white-glove inside delivery or help moving components to a backyard installation site, let us know at the time of order and we'll arrange it.

Inspect your delivery carefully before signing the freight bill. If you notice visible damage to boxes or pallets, note it on the delivery receipt before the driver leaves, this protects your damage claim. If concealed damage is discovered during assembly, contact our customer support team within 48 hours with photos. We will ship replacement components at no charge. We take full responsibility for any shipping-related issues.

Currently, standard shipping covers the continental 48 states. Delivery to Alaska, Hawaii, and international destinations is available with additional shipping charges and extended lead times. Contact us directly for a shipping quote to your location.

Yes. We can hold your completed order at our facility for up to 30 days at no charge. If you need more time, contact us, we'll work with you. We'd rather delay delivery than have your unit sitting at your home without a ready installation site.

Cold plunge water quality is important for both hygiene and equipment longevity:

• Weekly: Check and balance water chemistry (pH 7.2-7.6; sanitizer levels)
• Monthly: Clean the filter and inspect the pump inlet for debris
• Every 3-4 months: Full water change for units used daily
• Annually: Professional chiller service inspection

We provide a detailed maintenance guide and support line for any water chemistry or mechanical questions.

Interior: No. Cedar's natural oils provide inherent moisture resistance, and interior sealants can off-gas at high temperatures. The interior should be left untreated and cared for with light sanding as needed. Exterior: Yes. We recommend applying a penetrating UV-protective wood oil annually or as needed when the wood begins to look dry. Without treatment, cedar will naturally silver over time, which many customers consider beautiful. Sealing simply preserves the warm honey tone longer.

Our systems are designed for year-round use in all climate zones, including cold winters. For active winter use, the sauna generates its own heat and requires no special winterization. The cold plunge chiller should be protected with a weatherproof cover and insulation on exposed plumbing lines in climates that regularly drop below 20°F. If you choose to winterize:

• Drain the cold plunge completely and blow out lines
• Cover the sauna door opening with our weatherproof cover kit
• Disconnect and store the heater control unit indoors

We provide full winterization instructions specific to your configuration.

A high-end wellness club or spa membership with sauna and cold plunge access costs between $200-$600/month in most major U.S. markets. A Cielo system, amortized over 10 years, costs roughly $150-$230/month, and that's without accounting for the time you save (no commute, no waiting, no scheduling) or the home value it adds. Beyond the economics: people who own their system use it dramatically more often than those relying on a gym or spa. And frequency is everything when it comes to results.

Yes. We offer financing options through our lending partners with terms from 12 to 84 months. Qualified customers can access 0% APR promotional financing on select configurations. Contact us for current financing offers and to get pre-qualified. We can usually have a financing answer within 24-48 hours.
