A sauna between the vines is a reason to book the cottage in November — a bookable amenity without a staffed spa department. One building, one calendar, housekeeping turns it round.

Wellness by NOOK — for hospitality
Bookable wellness, craned into place.
Finished sauna, treatment and changing buildings for hotels, farm stays and resorts — composed around the pool and gardens you already own, on site in days. The sauna from $45,000 USD.

What we build
Not a spa wing. A wellness ground.
Three buildings, finished off-site and craned into place — the landscaping closes around them. Composed as a ground: heat, cold, treatment, changing.
NOOK Sauna — the anchor.
Finnish-style heat, booked by the private hour. The one priced building: from $45,000 USD.
The sauna, in full →
NOOK 10 — the single room.
Treatment, consultation, quiet room.
NOOK 20 — the double room.
Couples treatment that splits into two singles, recovery gym, studio, lounge — or, with a bathroom built in, the changing room that keeps a robed guest from walking back through reception.
Project-specific
Cold plunge, ice bath, hot tub — project-specific scope, sourced and clad to match your finish. Your pool stays yours — in every plan we draw it appears as a dashed outline.

Glamping & landscape hotels
In your category outdoor bathing has become the norm — 64% of new outdoor-stay spaces added it in the last two years, 85% among top performers (Canopy & Stars market report). Six reversible screw piles, no poured concrete — suited to leased sites, subject to landlord and local approval.
For glamping →The Ritual → Circuit
The boutique rural resort
You don't need the wing — you need the offer: heat, cold, a treatment room, somewhere to change. Production runs 8–12 weeks by scope; installation is days on site, not a construction season.

The estate hotel
Your guests already pay for this hour elsewhere: £220 for a private 90-minute sauna-and-plunge session at Gleneagles (listed price, gleneagles.com). The question isn't demand — it's whether the hour happens on your ground, connected to your changing, treatment and gardens.

The flagship resort
Operations, design and investment teams need one diligence pack, not a pitch: the system, the compositions on a real ground, delivery and reversibility, warranty terms — with drawings and the model to follow. That is what the dossier is for.

Why now
Wellness sells the stay.
The guest
Rest is the #1 stated reason for leisure travel — 56% in Hilton's 2026 Trends survey. Wellness travellers outspend average tourists: +41% per trip internationally, +175% domestically (Global Wellness Institute — 2022 travel data, published March 2024). And the culture is compounding: UK public saunas roughly tripled between 2023 and 2025 (British Sauna Society census), and six new bathhouses open in New York in 2026 alone (Wallpaper*, Feb 2026).
The trap
The traditional answer — the spa wing — carries years of construction and a payroll that never leaves. Across 297 US hotels, spa revenue grew 1.4% in 2024 while spa department profit fell 0.5% as labor costs rose 3.9% (CBRE Hotels Research, 2025).
In H1 2025, hotels with lighter wellness footprints out-earned the heavy builds on rate ($250 vs $232 ADR), revenue ($170 vs $161 RevPAR) and profit growth (+5% vs +2.9% GOPPAR) — RLA Global × HotStats, 11,000+ properties.
The data now favours the property that builds less, better. That is the property NOOK builds for.
The evidence
What the market is charging.
None of these are NOOK installations, and no affiliation is implied — they are the market evidence: listed prices and reported demand at named properties.

The asset case
One private hour, sold seven nights a week.
The unit of revenue is the private hour: a couple books the sauna and plunge to themselves, housekeeping turns it round like a room, and the calendar does the rest. Market price for that hour at the top of the category: £220 at Gleneagles, ~2,150 SEK at Grand Hôtel Stockholm — listed prices as checked July 2026. Your rate card sits where your property sits.
Session revenue
The bookable hour.
Rate effect
Rooms sold beside a wellness offer.
The listing effect
Wellness in the OTA filter.
For hotel, glamping and short-let segments we model payback at 18–36 months end to end — and the number that matters is yours: the design consultation brings the model in spreadsheet form, built on your ADR, your occupancy, your session pricing. Your inputs, our arithmetic.
A note on benchmarks: we do not treat any published sector uplift as a forecast for your property. Sector data tells you the category moved. The dossier model tells you what YOUR ground could do.
The year-round argument
Heat sells best against cold — and the buildings are specified for it, seven nights a week, in any month.
Who you're dealing with
Hospitality on one side of the table. Manufacturing on the other.
The founding team spans hospitality and manufacturing — the conversation starts with your masterplan, your operating model and your rate card, not our brochure.
Capacity
Production lines in Europe and the United States, routed by proximity. Line reservation for phased and multi-property projects.
Adaptability
One modular chassis, your palette: cladding, interior timber, water elements clad to match — plus sloped-roof, porch and terrace add-ons on the flat-roof base. It looks designed for your property because it was.
Logistics
Conventional transport. Delivered worldwide; transport and lifting are confirmed per building, route and site.
Quality & after-sales
Every component coded; each building ships with its own building file. Tempered safety glass EN 12150; heater electrical safety EN 60335-2-53; CE marked. Structural warranty: 1 year commercial, extendable to 3. After-sales run directly by NOOK.
We are early, and we price that honestly: the first installations get the photographer, named case-study terms, and priority slots on the line — in writing. Ask about the founding operator terms.

Asked before the dossier.
How should we treat the wellness statistics on this page?
As sector evidence, not a forecast. RLA Global × HotStats segment 11,000+ real hotel P&Ls by wellness footprint — they tell you the category moved, not what your property will earn. The model is built on your ADR, occupancy, room mix and session pricing, and comes as a spreadsheet with the design consultation so your revenue team can stress-test every line.
Can we start with just the sauna?
Yes — most properties should. The sauna is a complete bookable amenity from $45,000 USD, and The Ritual, The Circuit and The Garden are the growth path: add rooms as bookings prove demand. Production runs 8–12 weeks by scope; each building cranes in in under two hours.
What does a hotel wellness amenity actually earn?
Three mechanisms: booked private sessions (Gleneagles lists £220 for 90 minutes; Grand Hôtel Stockholm 2,150 SEK entry — listed prices, July 2026), the rate effect on rooms sold beside a wellness offer, and the listing effect in OTA filters. We model payback at 18–36 months for hotel, glamping and short-let segments — on your numbers, in spreadsheet form.
What certifications do the buildings carry?
CE marking; heater electrical safety to EN 60335-2-53; tempered safety glass to EN 12150. The dossier carries the compliance documentation component by component.
Can the buildings be removed later?
They are designed for it: six reversible screw piles per building, no poured concrete. The buildings can be craned out and the site reinstated — which is also the honest answer for leased sites, subject to landlord and local approval.
What's in the dossier?
The 11-page dossier: the system at a glance, the priced anchor with its floor plan, the flexible rooms, the three compositions drawn on a real ground, how delivery lands with the scope split, the reversibility case, and the warranty terms — the document you can put in front of your board. Drawings and the ROI model on your numbers follow with the design consultation.
