The Promise

Turnkey. Designed by specialists.

That's the work. Here's how we do it. We design your sauna, supply every material, and coordinate the install through our partner installer — overseen by our team from first measurement to final orientation. We coordinate directly with your electrician (or refer one we've worked with) so you're never middlemanning trades. You don't need to become a sauna expert. You say yes. We make sure the rest happens right.

"The quality of their work exceeded every expectation."
I recently had a custom-made sauna installed in my home, and I couldn't be more impressed. Nick, James, and Freddie did an absolutely outstanding job from start to finish. Their craftsmanship, attention to detail, and professionalism were truly first class. The sauna looks incredible, functions flawlessly, and feels like a true luxury addition to my home. A five-star experience all around.

"It has become the highlight of my daily routine."
Nick is a true professional who goes above and beyond to ensure customer satisfaction. He patiently answered all my questions and guided me through choosing the perfect sauna. The sauna itself is top-notch — beautifully crafted, easy to use. Since using it, I've noticed a significant improvement in my relaxation and overall well-being. Nick's dedication and expertise make all the difference.

"When I decided to use them, I felt they had earned my business."
They walked me through every step — helping me pick the right sauna, understanding the electrical, finding the right place in my yard. They explained everything about the wood, the heater, WiFi, and every detail that would affect my experience, and they were spot on. The delivery and installation was more than professional. I've been using it several times a week and everything works as advertised.

How It Works

From here to finished sauna.

Three steps. Most homeowners are surprised how simple it actually is.

1

Tell Us About Your Space

Share your room dimensions, location, and timeline. We'll have a quick conversation about what you're picturing and confirm the right approach for your home.

2

Get Your Free Design + Estimate

Within 48 hours, you receive a custom design of your sauna — bench layout, heater placement, ventilation, electrical — with a detailed itemized estimate.

3

Site Visit, Then Build

We come out for final measurements and answer every question. Once you're ready, we coordinate the build. Most projects complete in 8–12 weeks.

What's Included

The complete build.

Nothing left for you to source, guess, or figure out.

Custom Design

A detailed design of your sauna — bench layout, depths, heights, vent locations, heater placement, electrical routes — tailored to your exact room.

All Premium Materials

Sauna-grade wood, heater, pre-hung door, bench and backrest materials, vapor barrier, hardware, lighting, accessories — everything sourced and supplied.

Coordinated Installation

We assign a vetted partner installer to your project and oversee every detail from scheduling to walkthrough. You deal with one team: us.

Electrical Coordination

We work directly with your licensed electrician (or refer one we've used before) so you're never middlemanning trades.

Post-Install Orientation

Once your sauna is in, we walk you through how to use it — heat schedules, löyly technique, maintenance, controls — so you get every benefit from day one.

2-Year Warranty

The heater and wood are backed by a full 2-year ECS warranty. If anything fails, we replace it. No fine print.

Our Belief
Most people think a sauna is something you add to a home. We think it's something a home isn't quite finished without.
East Coast Saunas

We only take 8 new builds per month.

Every project is designed from scratch and overseen personally by our team. To protect that standard, we don't go beyond eight. If you're thinking about a build for this year, the conversation worth having is now.

Real Clients, Real Texts

What clients send us once it's in their home.

Unfiltered messages from homeowners who built with us. No edits. No marketing speak.

This is the part nobody tells you — once it's in your house, you'll wonder why you waited.

Common Questions

Frequently Asked

Most of our custom Long Island sauna projects are completed for $20,000 to $30,000, depending on room size, wood species, heater selection, and design features. Larger or higher-spec builds run higher. You'll receive a detailed itemized estimate within 48 hours of submitting your project details.

It's the question we hear most often. Honest answer: almost every client we've built for ends up using their sauna 4–7 times a week within the first month, and most tell us they wish they'd done it years sooner. We design the room and the daily experience to be frictionless — pre-set heat schedules, fast warm-up, easy access from inside the home — so it becomes part of how you wind down.

From first conversation to your first sauna session is typically 8–12 weeks on Long Island. You'll receive your free design and estimate within 48 hours. Once you say yes, materials arrive within about four weeks, and the build itself usually takes three to five days.

Yes. On Long Island, you make one decision: yes. We design your sauna, supply every material, coordinate the installer, and work directly with your electrician. You don't need to source materials, find an installer, or middleman trades. The whole project runs through us.

Electrical work must be performed by a licensed electrician (sauna heaters require dedicated high-amp circuits). You can use your own electrician — we coordinate directly with them so you don't have to middleman the back-and-forth. If you don't have one, we'll refer a licensed electrician who has wired saunas for us before.

The heater and wood are backed by a 2-year ECS warranty. If anything fails within that window, we replace it. Installation labor is covered separately by the installer team.

Everything we do is rooted in Nordic tradition — simplicity, purity, and real heat. The landmark studies demonstrating sauna's cardiovascular benefits were conducted on traditional Nordic saunas operating above 176°F. Infrared rooms typically don't reach above 150°F and strip away the two things that make a sauna a sauna: real steam (löyly) and high heat.
