Plunge pools · glass saunas · coastal Europe
Cold plunge pools and glass saunas, built to measure for Europe's coasts
We design and build the whole contrast circuit: a small built-in cold plunge pool held at 3–5 °C, a hot-and-cold pair when you want warmth too, and a glass sauna for one to twelve people. Made in our own workshop, sized for Mediterranean heat and Atlantic damp, drawn in 3D in up to five working days. For boutique hotels, holiday villas, padel clubs, clinics and private homes.
The collection
Start with the cold: what we build, and in what order
Plunge pools and hot-and-cold pairs come first because the cold side is what a circuit is organised around. Saunas, tubs and chillers follow, drawn on the same sheet so that the water, the heat and the plant room agree with each other.
Cold plunge pools built into the terrace
Round or square, glass mosaic or tile, flush with the floor and held at 3–5 °C. The machinery stays out of sight.

Warm pool, cold pool, one plant room
A 38 °C pool and a 4 °C pool side by side, with a sauna or without. One plant room, one drawing.
Read on
Glass saunas, one seat to twelve
One or two full glass walls, 1 to 12 seats, a Harvia heater and a view that fills the room.

Custom saunas cut to the room
A dry sauna sized to the alcove, basement or bathroom you have, from one seat to twelve.

Outdoor saunas that stand on a deck
Free-standing glass-walled cabins for gardens, roof terraces and pool edges, built to weather sun, salt and storms.

Wooden plunge tubs with a white liner
Oval or round tubs in ash or cedar with a white liner, 250 to 1,000 litres, for private homes.
Read onTwo coasts
The Mediterranean wants a bigger chiller; the Atlantic wants better stainless
Europe's coasts fail in different ways, so we draw for them differently. A pool that is still 4 °C in a Costa del Sol August and a sauna that is still tight after an Irish winter are the same promise made twice.
| Mediterranean coast | Atlantic coast | |
|---|---|---|
| Worst week | 38–40 °C air, dry, sun on every surface | cool, wet and windy, salt in the air |
| What fails first | the chiller's air path, and timber left in full sun | seals, fixings and anything that is not marine-grade stainless |
| What we change | size the chiller for 38–40 °C, shade the glass, give the plant room a real air path | membrane roofs with falls, sealed cladding, 316 stainless, drained decks |
| What the owner notices | water that is still cold in August | a sauna that is still tight in March |
Inland and mountain sites, such as Madrid, the Troodos foothills and the Italian lakes, add frost nights and big temperature swings to the list. The two notes to read first are cold plunge in a Mediterranean summer and salt air, timber, glass and steel.
Who it is for
A villa with a terrace, or a business with a rota
A household needs a pool that looks right and a plant room nobody notices. An operator needs documents, a duty cycle and a cleaning rota. Same workshop, two different drawings.
For villas and homes
A plunge pool in the terrace, a glass sauna in the garden or a timber tub on the deck: the house keeps its character and gains a place to cool down.
Villas and homes
For hotels, clubs and clinics
Wellness corners drawn for a rota: shared pools on a documented plant, saunas for eight to twelve, and drawings your architect and engineer can use.
Commercial projectsThe market
The audience, counted by people who are not us
We quote no return, because we have no source for one. What can be sourced is the size of the audience that a hotel, a club or a villa is already serving. Each figure names its publisher and its year.
| Figure | What it counts | Source |
|---|---|---|
| 75.5 million | members of health and fitness clubs in Europe at the end of 2025, up 5.8% on 2024, with revenue of €39.1 billion | EuropeActive and Deloitte, European Health & Fitness Market Report, April 2026 |
| 96.8 million | international tourists in Spain in 2025, a record | INE (Spain), Frontur, definitive data for 2025 |
| 951.6 million | nights booked through Airbnb, Booking and Expedia in the EU in 2025, up 11.4%; 189.5 million of them in Spain and 49.5 million in Portugal | Eurostat, short-stay accommodation offered via online platforms |

| $6.8 trillion | the global wellness economy in 2024, up 7.9% | Global Wellness Institute, Global Wellness Economy Monitor 2025 |
These describe markets. They are not our results, and they are not a forecast for your project or your return. What they let you say, truthfully, is that the people a recovery corner is built for are many and their numbers are growing.
Where we work
Seven countries and twenty-four places, each with its own set of questions
Spain first, then Portugal, Ireland and Cyprus; Italy, Greece and Croatia on request. Every place has its own page with the weather, the property types, the paperwork to ask about and a sample configuration with an indicative range.
The workshop
Joinery and chillers from our own lines, drawn together with the glass and the plant
The cabin, the tub and the chiller come off our own lines and are drawn together. That is why the heater, the glass and the water agree with each other about temperature.
Technical survey by video or laser, a workshop page that says what goes into each part, and payment in 40 / 40 / 20: deposit, production, delivery. The last instalment waits for a signed temperature test.
Gallery
Sixteen frames, pools first
Round pools, square pools with a seat edge, warm-and-cold pairs, then the saunas and tubs. Each frame has a button that asks about that exact option.
Kit builder
Compose a circuit, read the range, send it on WhatsApp
Choose the sauna size, the pool or tub and the extras. The builder adds the chiller by the litres (1 HP to 260 L, 2 HP to 570 L, 4 HP to 1,200 L), the heater by cabin volume, and shows an indicative range in euros.
How a project runs
Five steps from a phone photo to a signed temperature test
Photos and measurements

Free 3D layout
In up to five working days: the circuit drawn into your site, an equipment list, the power it needs and an indicative range.
Contract and 40% deposit
The specification, the schedule and the price are fixed. The deposit books your place in the workshop.
Six to ten weeks of making

Read onQuestions
Seven questions to settle before you write to us
How much does a custom sauna cost in Spain, Portugal or Ireland?
A four-seat glass sauna is indicatively €9,700–14,000, a two-seat cabin €7,100–9,700 and an eight-seat commercial cabin €18,500–26,000. A built-in cold plunge pool starts at €8,400. See the price list and the note on what an outdoor sauna costs.
Does a cold plunge pool stay cold in a 40 °C summer?
It does when the chiller is sized for it. We design Mediterranean pools for 38–40 °C air and let the chiller class follow the litres: 1 HP to 260 L, 2 HP to 570 L, 4 HP to 1,200 L. The machine stays out of sight and out of the sun. Details in cold plunge in a Mediterranean summer.
Do I need planning permission for an outdoor sauna?
It depends on the country, the region and sometimes the street, and we will not guess. Our note on permits compared gives what we could verify and the questions to put to your town hall.
Which countries do you cover?
Spain, Portugal, Ireland and Cyprus have full pages with local detail; Italy, Greece and Croatia are on request. See where we work.
How long from signature to first session?
The 3D layout takes up to five working days. Production takes six to ten weeks and assembly on site up to seven days. Delivery depends on the address; the layout carries the figure.
Can a holiday let have a sauna and a plunge pool?
Yes. Read the holiday-let circuit for what to plan around, and the page for holiday lets.
What does the warranty cover?
Everything we build carries a two-year warranty, with assisted service visits during the first year. Payment is 40 / 40 / 20, and the closing instalment is released only after the thermometer has been read and the test signed.
