Testimonials
“Ten out of ten. We are thrilled with Kai's design, quality materials, and craftsmanship of our sauna. His knowledge and expertise are outstanding. We will actually miss having him onsite, and are so grateful for the new gathering place he created for our family.”
— Jim & Andrea M.
“I’m blown away by the quality, materials, craftsmanship, and design from Kai. Every detail is so well thought out. Kai is an incredible craftsman—smart, meticulous, and detail-oriented. This sauna brings so much happiness into my life; I sleep better and feel better. I love that I can heat it up from my phone. It’s perfect! I highly recommend it. It’s even better than I expected, with high-quality insulation and attention to details you can’t even see (like real sheep wool insulation instead of synthetic alternatives, the best quality lumber, etc.).”
— Maria Gonzalez - Blanch
“We couldn't be happier with our new sauna from Kaiborg Builds. The entire process, from the initial site visit to completion, was seamless and professional. Kai's passion for his work is evident in the spectacular result—it looks and performs even better than we expected. We opted for the larger heater, and it heats up incredibly fast and stays hot too. The sauna has a wonderful, fresh scent, like a massive cedar forest. We highly recommend Kaiborg Builds for anyone looking for top-quality craftsmanship.”
— Dave C.
“Kai brings a high level of professionalism and attention to detail to his work. He adjusted and customized an outdoor sauna design to sit perfectly within our preferred outdoor space. The finished product has exceeded our expectations and we’ve been beyond satisfied after several months of daily use. I’d highly recommend Kai to anyone considering installing a home sauna.”
— Billy B.

Frequently Asked Questions
-
Barrel saunas look great in photos, but most people don't realize how much performance they're giving up. They underperform in heat retention, durability, and usable space — and that adds up over time.
Our cabin saunas are craftsman-built to outperform in every category: robust framing for structural integrity, premium insulation for faster heat and lower energy use, proper moisture protection to extend lifespan, and better space efficiency so every square foot works harder.

It comes down to size and capacity. The Vesper is our compact model — a 1–5 person sauna with a 60" x 80" footprint and a 4.5kw Huum Drop heater, perfect for individuals, couples, or small households. The Vesper XL steps up to 1–7 people with a 70" x 90" footprint, ideal if you want more bench space or entertain with friends. The Ember is our largest build — a 1–9 person sauna at 82" x 100" with a more powerful 9kw Huum Cliff heater and an L-shaped bench layout that offers deeper, more spacious seating. All three share the same height, modern cabin aesthetic, WiFi control unit, and upgrade options including red light therapy and under bench lighting.
-
We use beautifully designed Huum Brand heaters with wifi capable controllers, allowing you to control your sauna heater from the Huum mobile app.
-
We have options for heater upgrades, glass door variations, red light therapy and under bench lighting.
-
We use Havelock sheeps wool, the best in the business. Non-toxic and the most sustainable insulation on the market.

A concrete pad is best, but we can place our units on level gravel or pavers as well.
-
No. No volatile or toxic chemicals are used anywhere in our Saunas, keeping our saunas clean, healthy and smelling with beautiful cedar aromas.
-
For the interior, wipe down the benches regularly with a damp towel — occasionally with a small amount of diluted natural soap for a deeper clean. For the glass door, we recommend Bioclean glass cleaner (available on Amazon). On the outside, a fresh coat of stain once a year keeps it protected and looking great.
