Custom indoor sauna space
Custom Indoor Sauna Design · New York · New Jersey · Connecticut

Custom indoor saunas designed as part of your home.

Every Cielo indoor sauna is thoughtfully designed around your space, handcrafted by our team, and professionally installed throughout the New York Tri-State Area.

Designed around your home, not adapted to it.

Designed Around the Room You Have

Your room is not a limitation.
It is the starting point.

Cielo studies the ceiling height, existing framing, electrical capacity, moisture path, and the materials already in the room before a single design decision is made. That might mean transforming an underused basement into a dedicated wellness space entirely - the same approach that turned one New Jersey basement into a custom seven-person sauna with its own dedicated zone, alongside a separate home gym. Or it might mean building a sauna and cold plunge directly into an existing bathroom footprint, matched to the same stone and tile already specified for the room. Almost any underused space in your home - a basement, a spare room, a primary bathroom - has the potential to become that wellness space. The result isn't a sauna installed in your home. It's engineered to read like it was always there.

The Real Question Isn't Whether - It's How It's Finished

Built to match the room, not interrupt it.

Indoors, a sauna sits inches from your existing materials - the same tile, stone, and cabinetry already specified for the room around it. That's why material selection is part of the design conversation from the first site visit: cedar or Kelo wood tones considered against your stone and millwork, glass and hardware finished to match existing fixtures, and mechanical components - chillers, vents, controls - planned to stay out of view rather than added as visible equipment afterward.

Your home shouldn't have to accommodate a prefabricated wellness structure. The structure should be engineered to belong to your home. Its ceiling height. Its materials. Its electrical capacity. Its layout. Considered first. Built second.

Longevity isn't a single session. It's a routine you can actually sustain.

Longevity isn't built in a single session - it depends on whether a routine survives contact with daily life. An indoor build makes that distance as short as it can be - steps from the bedroom, the gym, or the kitchen, not a separate trip outside. Cielo designs around that reality, so a consistent routine becomes part of how the room is used every day, not a feature that goes quiet after the first season.

Two Real Starting Points. No Fixed Footprint.

Every Cielo indoor project begins with the room - a basement, a primary bathroom, a spare bedroom, or a garage all call for a different approach. A full room build and a suite-integrated build are two proven directions, not fixed models. Once your space has been studied, either can be developed into something fully bespoke.

Full room build - basement transformed into a custom sauna and wellness space

Room Build

Designed for a basement, spare room, or garage where the goal is transforming unused square footage into a dedicated wellness space, built from the studs out. Walls, framing, and layout can be reconfigured entirely - the same approach that turned one New Jersey basement into a custom seven-person sauna with its own dedicated zone, engineered ventilation, and app-based control over temperature, humidity, and lighting.

Suite-integrated build - sauna and cold plunge built into an existing bathroom footprint

Suite-Integrated Build

Designed for a primary bathroom or en-suite, where a sauna and cold plunge are built directly into the existing footprint - wet and dry zones properly separated, materials matched to the stone, tile, and cabinetry already specified for the room, and mechanicals like a chiller concealed rather than left in view.

And for a room with a more specific structural or material requirement, many Cielo indoor projects become fully bespoke once the space has been studied - layout, materials, and integration developed from a blank page:

From Room Study to Installation

Your room. Our starting point.

Consultation

Complimentary · 30 min

Cielo begins at your property, not a showroom. We study the room's ceiling height, framing, electrical capacity, and moisture path, and how the space will fit your daily routine, before a single design decision is made.

Site-Specific Design & 3D Renders

1–2 weeks, typical

We develop the layout, materials, and relationship to the surrounding room - matched to existing stone, tile, or millwork where relevant. You review detailed renders before fabrication begins.

Precision Fabrication

6–10 weeks, typical

Handcrafted in clear cedar, insulated glass, and precision aluminum, built to the approved site-specific design and engineered for genuine daily use.

White-Glove Installation

1–3 days, typical

Cielo coordinates delivery, site protection, placement, and final commissioning, with a walkthrough before the project is considered complete. A suite-integrated build working within existing plumbing typically installs faster than a full room build involving new framing or wall removal.

Timelines above are typical planning ranges. Permitting, structural scope - such as wall removal or new framing - and the extent of customization can extend either phase, reviewed in detail during your consultation.

Frequently Asked Questions

Every Cielo indoor sauna is a fully custom design - there's no fixed lineup of models to choose from. Almost any room can become a dedicated wellness space: from a compact suite integration to a full basement transformed into a custom seven-person build.

That's the starting question, not an afterthought. Cedar or Kelo wood tones, glass, and hardware are selected against your existing stone, tile, and cabinetry, so the finished room reads as one continuous space, not two competing ones.

Often, yes. A 7 to 8-foot ceiling is ideal, and some states, including New Jersey, require a 7-foot minimum for finished, habitable basement space specifically. Every room is measured and assessed individually before a design is finalized.

Through a continuous vapor barrier, a two-vent system, and - for suite-integrated builds - a properly separated wet and dry zone. This is well-established building-science practice, planned into the design from the start rather than addressed after the fact.

At minimum, a dedicated circuit sized to the heater - infrared systems typically need 15 to 20 amps, with larger traditional heaters sometimes requiring more. This is planned early, ideally before walls and finishes are set.

Requirements vary by municipality and by the scope of electrical, plumbing, or structural work involved - nearly every real indoor build needs a permit somewhere. Cielo can help identify what your specific project requires and coordinate with the appropriate architect, engineer, or local building department as needed.

It depends on the scope. A suite-integrated build working within an existing bathroom footprint is typically less disruptive than a full basement or spare-room build involving new framing or wall removal - both are reviewed honestly during your consultation, not glossed over.

About five minutes of care after each use, a weekly wipe-down, and a professional heater and electrical check about once a year - the same upkeep as any well-built indoor sauna, regardless of room type.

Yes - a cold plunge can be built to fit a tight footprint alongside the sauna, with the chiller concealed and engineered ventilation built in, the same approach used in Cielo's own completed suite-integrated projects.

Design typically runs 2 to 3 weeks and fabrication 4 to 6 weeks. Installation varies more than an outdoor build - a suite integration with existing plumbing often finishes in days, while a full basement or room build involving new framing can take longer. Your consultation will lay out a realistic timeline for your specific scope.

Yes. When a project is part of a larger renovation, Cielo works within that existing team - architect, builder, or contractor - to keep the sauna's electrical, ventilation, and layout requirements aligned with the rest of the project.
