Designed Around Your Home
Every Summit sauna is built for one home — yours.
No two mountain homes are alike, and no two Summit saunas are either. We design every environment from the ground up — dimensions, materials, glass, light, and heat — so the finished sauna feels inevitable within your architecture, not added to it.

Sauna Experiences
Four ways to experience the heat.
From high-temperature Finnish tradition to full wellness suites — every Summit experience is engineered around how you actually live in the mountains.
02
Outdoor Mountain Sauna
Standalone sauna structures designed for snow, altitude, mountain views, and extreme Rocky Mountain conditions.
03
Luxury Indoor Sauna
Architecturally integrated sauna rooms for primary bathrooms, wellness spaces, home gyms, and private spas.
04
Steam + Wellness
Optional wellness environments combining sauna, steam, cold plunge, showers, and dedicated relaxation areas.
Materials
Selecting wood like fine architectural finish.
We build exclusively with four species, each chosen for how it looks, feels, and performs inside a working sauna. No substitutions — only the right wood for the right application.
01
Aspen
The Nordic Standard
Pale, whisper-soft in tone with a clean, almost snow-like finish, Aspen is the traditional benchmark of fine sauna craftsmanship — chosen for its purity as much as its performance.
Appearance
Creamy white to pale straw, with a soft, uniform tone that brightens any interior.
Grain & Texture
Fine, straight, and understated — a smooth, almost silken surface with minimal visible grain.
Feel Against Skin
Naturally low resin content keeps surfaces cool and comfortable, even at high heat.
Heat Performance
Excellent heat tolerance with minimal expansion; stays comfortable on benches and backrests.
Durability & Stability
Lightweight and stable in fluctuating humidity; resists warping in traditional use.
Best Applications
Benches, backrests, and wall paneling in traditional Finnish-style interiors.
02
Thermally Treated Aspen
Aspen, Deepened by Heat
A thermal-treatment process transforms Aspen's pale complexion into a rich, coffee-toned wood — adding warmth and depth while enhancing its natural performance.
Appearance
Deep caramel to espresso brown, with rich tonal variation from the thermal process.
Grain & Texture
Heat treatment draws out subtle grain patterning for a more dimensional surface.
Feel Against Skin
Retains Aspen's cool-to-touch quality with a smoother, slightly burnished surface.
Heat Performance
Thermal modification improves moisture resistance and reduces expansion over repeated cycles.
Durability & Stability
More dimensionally stable than raw Aspen — suited to humid, high-cycle environments.
Best Applications
Feature walls, ceilings, and benches where a darker, architectural palette is desired.
03
Abachi
The Quiet Luxury Wood
Prized in European sauna design, Abachi offers an exceptionally light, low-density structure that stays remarkably cool — a favorite where comfort and refinement matter most.
Appearance
Pale blonde with a soft, even tone and subtle luminosity.
Grain & Texture
Very fine, tight, and consistent grain; sands to a glass-smooth finish.
Feel Against Skin
Among the lowest thermal conductivity of sauna woods — exceptionally comfortable at peak temperature.
Heat Performance
Outstanding heat tolerance with very low resin bleed and minimal surface heating.
Durability & Stability
Naturally resistant to warping; performs beautifully through high-heat, high-humidity cycles.
Best Applications
Benches, headrests, and any surface with direct, prolonged skin contact.
04
Thermally Treated Abachi
Modern. Espresso-Toned. Refined.
Heat-treated to a deep espresso tone while retaining Abachi's signature coolness underfoot, this wood defines the modern, architectural sauna interior.
Appearance
Rich espresso to dark chocolate brown, with a matte, sophisticated finish.
Grain & Texture
Fine, tight grain with subtle depth drawn out by the thermal process.
Feel Against Skin
Retains Abachi's naturally low thermal conductivity — cool, smooth, and comfortable at heat.
Heat Performance
Enhanced moisture resistance and dimensional stability from thermal modification.
Durability & Stability
Highly stable across repeated heat and humidity cycles — ideal for daily use.
Best Applications
Accent walls, contrast benches, and minimal interiors pairing dark and light tones.
The Summit Process
From first conversation to first heat.
01
Consultation
We start by understanding your home, your space, your architecture, and the sauna experience you're after — whether that's a quiet daily ritual or a full wellness retreat.
02
Design
We develop the full sauna design: layout, wood species, glass, lighting, heater selection, and every architectural detail that will make it feel built-in, not built-on.
03
Visualization
Before a single board is cut, you'll see realistic 3D renderings of your sauna — so every material, dimension, and detail is confirmed before construction begins.
04
Build
Our team fabricates and installs with precision, coordinating closely with your builder, architect, or interior designer to keep the project moving on your timeline.
05
Experience
We complete final commissioning and hand off a fully finished sauna — tested, calibrated, and ready for its first true mountain heat.
Selected Projects

Why Summit Saunas
Considered. Engineered. Built to last at altitude.
Built for Altitude
Every design accounts for mountain climates — snow load, dry air, temperature swings, and elevation.
Architectural Integration
The sauna should look like it was always part of the house — never an afterthought or add-on.
Precision Craftsmanship
Premium materials, exacting joinery, and meticulous installation — down to the smallest detail.
Complete Design + Build
One team, start to finish — from initial concept and 3D visualization through final installation.
Our Story
A Rocky Mountain ritual, built into your home.
"There's a particular kind of quiet that arrives with heat after a cold day in the mountains — after the last run, the last summit, the last mile on the trail. We build spaces designed around that exact moment."
Summit Saunas started with a simple observation: the people who love these mountains most — skiers, climbers, trail runners, and the families who chase every season here — deserved a sauna that matched the caliber of the homes they'd built. Not a prefab box in the corner of a basement, but a considered architectural space, built from real timber, real glass, and real craftsmanship.
Today we design and build custom saunas for homes across Aspen, Vail, Telluride, Breckenridge, and the private residences in between — working directly with homeowners, architects, and builders to create wellness spaces that feel less like an amenity and more like the reason you built the house.
