Hot Tub Hotels in Key West, Florida
Key West is warm for most of the year, so a hot tub here is less about warming up than about slowing down: an evening soak after Duval Street, Mallory Square at sunset or a day on the water. The hotels on this page list a hot tub, and many are small adults-only inns in Old Town with tropical gardens, wine hours and breakfast, while a few larger properties suit families. The Capitana Key West and the Hyatt Vacation Club at Windward Pointe both show 9.0, and the Almond Tree Inn and Orchid Key Inn lead the page at 9.4. Ratings run from 8.2 to 9.4.
Key West is a small, sun-soaked island at the end of the Florida Keys, known for Duval Street, sunset gatherings at Mallory Square, the Southernmost Point and a relaxed, artistic and slightly eccentric character. Old Town's historic streets are best explored on foot or by bike, and the pace slows in the evening, which is when a hot tub fits.
Where to stay
Tropical hot tubs from Old Town to beach
A hot tub in Key West is a social and sensory pleasure, in a tropical garden or on a sundeck, rather than a necessity against the cold. The group splits clearly into adults-only inns in the historic center, family-friendly beachfront hotels and an apartment-style resort with kitchens, so the first decision is the kind of trip you want. I describe each for what it lists, and I would note that adults-only rules mean these inns are not for children.
The Almond Tree Inn, adults only, and the Orchid Key Inn, adults only, share the top rating at 9.4, from 298 and 285 reviews. The Almond Tree lists an outdoor pool and hot tub, complimentary breakfast and a historic location, and the Orchid Key lists a heated pool, a hot tub, an on-site bar and a historic location. I would choose the Almond Tree for a quiet breakfast-and-pool stay and the Orchid Key for a couple who like a bar on site. Both sit in the historic center, and their review samples are decent, though smaller than the large hotels.
Two more adults-only inns stand out for their atmosphere. The Paradise Inn, rated 8.8 from 768 reviews, lists an outdoor pool and hot tub, complimentary breakfast and a wine and cheese hour, which gives guests a social evening ritual. The Seascape Tropical Inn, with 8.7 from 499 reviews, lists a hot tub, two sun terraces, a tropical garden and a deluxe breakfast, and I would choose it for guests who want a garden setting and a generous morning meal. Eden House, an Art Deco hotel rated 8.8 from 595 reviews, lists a pool, a hot tub, tropical gardens and a sundeck, and it is the character choice if children are in the party.
For families, the Capitana Key West scores 9.0 from 2,942 reviews, which is the largest sample here, and lists a beachfront location, a private beach area, an outdoor pool and hot tub, and family-friendly rooms. I would choose it for a family that wants beach access and a hot tub in the same property. The Courtyard by Marriott Key West Waterfront has 8.2 from 372 reviews and lists a beachfront location, a heated outdoor pool, a hot tub and a family-friendly policy, a simpler brand-name option. Rates, hours and conditions change by season, so I would confirm them on the booking page before deciding.
The Hyatt Vacation Club at Windward Pointe, rated 9.0 from 925 reviews, lists apartments with kitchens, a year-round outdoor pool, a hot tub and private balconies. It is the one I would choose for a longer stay or a group that wants to cook and have space, because the apartments change the feel of a trip. Key West is a small island, so distances between these hotels and Duval Street are short by bike or on foot, but I would check each address on the map before booking, as the beachfront hotels sit farther from Old Town.
A traveler's perspectiveI would choose the Almond Tree Inn or the Orchid Key Inn for a couple's stay, because their 9.4 ratings, hot tubs and historic Old Town locations suit a quiet, adults-only trip. For a family, I recommend the Capitana Key West, with its beachfront location, hot tub and 2,942 reviews behind a 9.0. Our advice is to check whether an inn is adults only before booking, to use a bike in Old Town, and to keep the hot tub for the evening.

Orchid Key Inn - Adults Only
Key West
285 reviews
Historic adults-only inn with a heated pool and a lively bar on Duval Street
Check availabilityWhy guests love itOrchid Key Inn is adults only, so I would not suggest it for a stay with children, whatever its labels say.

Rooms have a flat-screen TV and a Keurig coffee machine, and some suites add a spa bath. Guests rate it 9.4 out of 10 over 285 reviews.

Key West
298 reviews

The outdoor pool, hot tub and sun deck are on site, a continental breakfast is included, and a happy hour offers free drinks.

For couples, it scores 9.3 out of 10 across 166 reviews. The year-round outdoor pool, the hot tub, the sun terrace and the garden make a calm base, and rooms are air-conditioned with garden views. South Beach, the Ernest Hemingway Home and Museum and Duval Street are close by. I recommend it to adults who want a garden-focused stay near Old Town.

Duval Street is within walking distance, and bicycle rentals make it easy to explore the island together. An 8.8 score from 595 reviews is very good for an independent hotel.

Local tips
- 1Check whether the inn is adults only before booking, since several of these hotels do not accept children.

- 3Watch the sunset at Mallory Square, then return to the hot tub at your inn for the evening.
- 4Ask about hot tub hours and the pool schedule, as small inns may close shared areas at night.
- 5Book early for winter and holiday weekends, when the best-rated small inns in Old Town fill first.
- 6Choose the Hyatt Vacation Club or a similar apartment-style stay if you want a kitchen for a longer visit.
