Section I · The Ranked Twelve
From best to twelfth.
Sorted by what each spa actually delivers. Therapist on call. Steam that holds temperature. A treatment room that does not double as a yoga studio.
No. I
The Provence eight-bedroom mas with hammam and indoor pool.
Bedrooms: 8. Sleeps: 16. Region: Luberon, Provence. Peak rate: $32,000 to $48,000 / week. Spa: 90-square-meter wing with stone hammam, dry sauna, 12-meter indoor heated pool, two treatment rooms, on-call therapist booked through the manager. Included: housekeeper, gardener, daily breakfast, one car. Not included: therapist sessions ($180 to $260 per 60 minutes), chef.
Why it ranks here: the spa is built into the property as a building, not retrofitted into a basement. Stone walls, lime-plastered hammam, a steam temperature that holds at 45°C for an hour without dropping. The therapist runs a four-person rotation through the local agency and the same names return year over year. We tested the indoor pool in November 2024, water temperature 30°C, lap-swimmable, no chlorine smell.
What we would change: the cold plunge is missing. A 3 by 1.5 meter plunge tank in the courtyard would close the loop. The owner has been told.

No. II
The Ubud six-bedroom estate with stone hammam and two treatment rooms.
Bedrooms: 6. Sleeps: 12. Region: Ubud, Bali. Peak rate: $14,000 to $22,000 / week. Spa: river-side pavilion with stone hammam, two treatment rooms, plunge pool, full-time therapist (six days per week). Included: full staff (five), two daily meals, chef, airport transfer. Not included: spa treatments above two per guest per week ($45 to $80 per session), boat days.
Why it ranks here: Bali is where the spa-included math works at the lowest price point on this list. The villa runs a daily massage allowance of two sessions per guest. For 12 guests across seven days that is functional spa infrastructure at $1,200 above the headline rate, which is what the same therapist hour costs in Provence. The pavilion is across a river, so it is properly separated from the main villa and reads as a destination.
What we would change: the second treatment room is too small for couples treatments. The owner could redesign it.

No. III
The Tuscany ten-bedroom estate with cypress-clad spa wing.
Bedrooms: 10. Sleeps: 20. Region: Val d’Orcia, Tuscany. Peak rate: $58,000 to $85,000 / week. Spa: 140-square-meter wing with hammam, dry sauna, infrared sauna, 15-meter indoor pool, three treatment rooms, gym, vitality pool. Included: full staff (eight), two cars, daily breakfast and dinner service. Not included: therapist (booked through the on-site spa manager at $200 to $300 per 60 minutes), wine, transport.
Why it ranks here: the largest spa on the list. Three treatment rooms run in parallel, so a group of six can book a slot simultaneously without the queue. The vitality pool with rotating jets is the upgrade most large-villa spas miss. The infrared sauna sits next to the dry sauna, which is the right configuration for anyone who alternates.
What we would change: the spa is in the cellar of the main building. Daylight is the missing element. The owner has been told. A retrofit is unlikely.

No. IV
The Mallorca finca with cedar sauna and lap pool.
Bedrooms: 7. Sleeps: 14. Region: Serra de Tramuntana, Mallorca. Peak rate: $28,000 to $42,000 / week. Spa: cedar dry sauna, steam room, 20-meter indoor lap pool, one treatment room, hot and cold plunge. Included: full staff, daily breakfast, one car. Not included: therapist, chef, second car.
Why it ranks here: the only spa on the list with a 20-meter indoor lap pool that lap-swimmers will use. The temperature holds at 29°C, no overpowering chlorine, and the pool runs the full length of the wing without an obstruction. Cedar sauna heats to 90°C in 35 minutes from cold, which is the test. The contrast bath setup (38°C hot, 12°C cold) is the best on the list.
What we would change: the treatment room is single only. Couples treatments require booking the room twice in sequence.

No. V
The St Barts five-bedroom with cliffside spa pavilion.
Bedrooms: 5. Sleeps: 10. Region: Pointe Milou, St Barts. Peak rate: $42,000 to $68,000 / week (low season $18,000 to $26,000). Spa: open-air pavilion with one treatment room, infrared sauna, outdoor shower, plunge pool. On-call therapist via Wellness St Barth. Included: housekeeper, gardener, one car. Not included: therapist, chef, dedicated pool staff.
Why it ranks here: the pavilion is the right answer for the climate. Indoor spa in St Barts is over-engineered. This is a roofed, screened structure on a cliff with the treatment table facing the water. Therapist is booked separately and arrives within two hours of inquiry in season. The infrared sauna is a real upgrade over the typical Caribbean “outdoor wellness deck.”
What we would change: no hammam or steam. For a winter trip with rain on the schedule, the spa is less useful than the indoor options higher on this list.

No. VI
The Lake Como historic villa with restored Roman-style bath.
Bedrooms: 9. Sleeps: 18. Region: Tremezzina, Lake Como. Peak rate: $65,000 to $98,000 / week. Spa: restored 19th-century bath with three chambers (caldarium, tepidarium, frigidarium), 8-meter indoor pool, two treatment rooms, dry sauna in the adjacent wing. Included: full staff (nine), butler, two cars, boat with skipper, daily breakfast service. Not included: chef, therapist, fuel for boat above eight hours per week.
Why it ranks here: heritage spas are usually a sales point and a structural disappointment. This is the exception. The original 1890s bath was restored in 2019 with modern plumbing and water filtration, and the temperature gradient across the three chambers (38°C, 28°C, 14°C) is the closest analog on the list to a working Roman bath. The pool is small but the marble surround is real.
What we would change: the dry sauna sits in a separate wing 40 meters from the bath. The transition in winter requires a robe and slippers. The owner could connect the two with an interior corridor.

No. VII
The Marrakech riad with traditional hammam and steam.
Bedrooms: 6. Sleeps: 12. Region: Palmeraie, Marrakech. Peak rate: $18,000 to $28,000 / week. Spa: tadelakt hammam, steam room, two treatment rooms, plunge pool, on-call therapist seven days per week. Included: full staff, three meals per day, transport within Marrakech, two daily hammam slots per guest. Not included: spa retail products, alcohol.
Why it ranks here: the spa is the most embedded on the list. Hammam is a daily part of the property routine here, not a feature. Tadelakt walls hold heat in a way that cement-finished “hammams” elsewhere do not. Therapist runs the room six full days per week and the treatment menu is real, not a hotel-style upcharge.
What we would change: Palmeraie location is 25 minutes from the Medina. For a trip where the Medina is the point, that drive accumulates. Book a town riad for those days.

No. VIII
The Aspen lodge with snowmelt plunge and dry sauna.
Bedrooms: 7. Sleeps: 14. Region: Red Mountain, Aspen. Peak rate: $85,000 to $120,000 / week (winter peak). Spa: dry sauna, steam room, snowmelt cold plunge fed from the roof in winter, 10-meter indoor pool, two treatment rooms, gym. Included: full staff (seven), chef, ski concierge, two SUVs with chains. Not included: ski passes, therapist (booked through Remede or local independent at $250 to $400 per session).
Why it ranks here: the snowmelt plunge is a gimmick that works. The roof catchment fills a 2 by 2 meter tank with melt water at 4°C and the post-ski cycle (sauna, plunge, sauna) is the property’s signature. The gym is well-equipped (rower, two Peloton bikes, free weights to 50 kg) and the chef is a known quantity, ex- a Snowmass restaurant.
What we would change: the spa is undersized for 14. Two treatment rooms is one short for a group looking to book simultaneous sessions on weather days.

No. IX
The Costa Smeralda six-bedroom with sea-view treatment room.
Bedrooms: 6. Sleeps: 12. Region: Porto Cervo, Sardinia. Peak rate: $48,000 to $72,000 / week. Spa: two treatment rooms with sea view, sauna, steam, 6-meter indoor pool, gym. Included: full staff (six), beach club concierge, one car. Not included: therapist, chef, boat days.
Why it ranks here: the only spa on the list with a treatment table that faces the water directly. Both rooms have west-facing windows that open. The 6-meter indoor pool is undersized for laps but right for a soak between treatments. The price is high for what the spa delivers; the location is doing most of the lifting.
What we would change: the spa shares a building with the gym and the acoustic separation is poor. If two parties book gym and treatment at the same time, the bass tones bleed.

No. X
The Algarve cliff villa with thalassotherapy pool.
Bedrooms: 5. Sleeps: 10. Region: Carvoeiro, Algarve. Peak rate: $16,000 to $26,000 / week. Spa: thalassotherapy pool (seawater, 32°C, hydro-jets), one treatment room, sauna, outdoor shower. Included: housekeeper, daily breakfast, one car. Not included: therapist, chef, beach concierge.
Why it ranks here: the thalassotherapy pool is rare and properly engineered. Seawater is drawn from below the cliff and heated to 32°C with a rotating jet program (legs, lower back, upper back). The treatment room is competent rather than special, but the pool is the reason to book.
What we would change: the access stairs to the cliff beach are steep and unlit at night. For anyone with mobility concerns, this villa is the wrong answer.

No. XI
The Mykonos five-bedroom with infrared sauna and ice plunge.
Bedrooms: 5. Sleeps: 10. Region: Aleomandra, Mykonos. Peak rate: $26,000 to $38,000 / week. Spa: infrared sauna, ice plunge (3°C), one treatment room, gym. Included: full staff, one car. Not included: therapist, chef, second car.
Why it ranks here: the only spa on this list that took the cold-exposure trend seriously. The plunge runs at 3°C reliably, with the chiller sized correctly for repeat dunks. Infrared sauna is the right call for a hot climate. The treatment room is functional. For a Mykonos group that wants spa as part of the routine and not the only feature, this works. See our main Mykonos best-of for context on neighborhood and the rest of the property.
What we would change: no steam or hammam. The spa is dry-only, which suits some and not others.

No. XII
The Hamptons estate with indoor pool and treatment suite.
Bedrooms: 8. Sleeps: 16. Region: Sagaponack, the Hamptons. Peak rate: $75,000 to $110,000 / week (Memorial Day to Labor Day). Spa: 14-meter indoor pool, dry sauna, steam, two treatment rooms, gym, recovery suite (cold plunge plus Normatec compression). Included: housekeeper, gardener, pool staff. Not included: chef, therapist, beach club access.
Why it ranks here: the recovery suite is the post-2020 wellness install done correctly. Normatec boots, a 4°C plunge, and a red-light therapy panel. The indoor pool runs at 28°C and the spa is on a separate HVAC zone, so the recovery temperature does not bleed into the rest of the house. The price is the issue (Hamptons math is its own category), but as a spa property the configuration is right.
What we would change: the treatment rooms share a wall with the gym. Same issue as the Sardinia villa. The owner should have rooms 1 and 2 on opposite ends.
