The Wellness One Therma is a mid-range outdoor sauna available in three sizes (S, M, L) with two finish levels — Base and Therma — each fitted with an electric heater. Pricing is by personalised quotation. The Therma carries a 2-year warranty and offers a genuine sauna experience at an accessible price point.
Not Everyone Wants the Flagship. That's Fine.
Let's be honest about something the luxury market rarely admits: not every buyer needs the top of the range.
Some people want a genuine, properly constructed sauna that heats properly, holds its temperature, looks handsome in the garden, and doesn't cost what a small car costs. That's not a compromise. That's a sensible purchase.
The Therma exists for exactly this buyer. And we built it without apology.
What the Therma Is
Three sizes — S, M, and L — because sauna sizing should match your space and your household, not a marketing upsell.
Two finish levels. Base is the foundation: a clean, well-built sauna with electric heater, ready to use. Therma adds a higher specification of interior finish and detailing. Both are real saunas. Both heat properly. Both are built to a standard that we're comfortable putting our name on.
The electric heater is included in every configuration. No chasing third-party suppliers, no compatibility concerns, no guesswork about kilowatt ratings for your space.
Why Personalised Quotation?
We could put a price on the website. We choose not to, and here's why.
The Therma is configurable. Size, finish level, and the specific requirements of your installation all affect the final figure. Putting a headline price online either means quoting the cheapest possible configuration (which feels dishonest) or the most expensive (which puts people off before they've even had a conversation).
Instead, we quote accurately based on what you actually want. It takes one conversation. We'll give you a clear number with no hidden costs, and you can make your decision with real information rather than asterisked estimates.
The Sauna Experience
Here's what doesn't change between Therma and our premium ranges: the fundamental experience of sitting in a properly heated enclosed space while your muscles unknot, your breathing deepens, and the accumulated static of your day drains away through your feet.
The physics of sauna are beautifully simple. Heat the air. Heat the stones. Pour water.
The Therma delivers all of this. The heater reaches temperature. The room holds heat. The stones accept water. The experience is real.
Who the Therma Is For
First-time sauna buyers who want to experience the real thing before deciding whether to invest in a larger installation later.
Homeowners with modest gardens where the smaller S model fits perfectly without dominating the space.
Rental property owners who want to add a genuine wellness amenity without the capital outlay of the Lifestyle or Connect ranges.
Anyone who's done their research and concluded that they want a proper sauna — not a cheap barrel off the internet that smells of wet plywood by its second winter — but doesn't need the premium specification of our flagship ranges.
What the Therma Is Not
We won't pretend the Therma is the same as the Lifestyle or Connect. The construction specification is different. The warranty is two years rather than five. The material choices reflect the price point.
What it is, however, is honest. It's a genuine sauna built by a company that takes saunas seriously. It heats properly. It's built to last its warranty and beyond. And it gives you the actual, physiological, deeply pleasurable experience of a real sauna session in your own garden.
We'd rather sell you a Therma that meets your needs than upsell you a Lifestyle that stretches your budget. That's not a sales line — it's how we keep customers who come back when they're ready to upgrade, and who send their friends to us in the meantime.
Two Brochures, Clear Information
We've produced separate brochures for the Base and Therma finish levels, both available to download from our website. They contain full specifications, dimensions, imagery, and enough detail to have an informed conversation with us when you're ready.
Getting Your Quotation
Contact us directly. Tell us the size you're considering, whether Base or Therma finish appeals, and anything specific about your installation — garden access, base preparation, electrical supply.

A sauna is a considered purchase. We respect that.
