Sunseekers on spring break and families embarking on theme park vacations are well-known for flocking to Florida throughout the year. Still, there's a steamier side to Florida's sultry shores and sparkling blue water, one that inspires relaxation and decadence -- in short, luxe, romantic spa treatments. In fact, Florida's sexiest spas may open your eyes to a world of indulgent possibilities. Whether you and your partner are keen to unwind with side-by-side massages, dip naked into an oil-infused "Love Bath," or drip hot wax on each other's backs while learning ancient massage techniques, we're sure these sexy spas will satisfy.

You might find your heart skip a beat as you and your partner enter the Ritz-Carlton Spa on Key Biscayne through a private entrance and are transported into a calming oasis, complete with a soothing waterfall and mango-scented candles. You'll be hard-pressed not to rekindle romance after paying a steamy visit to the spa's sauna, followed by time in the eucalyptus steam room and whirlpool. Lie together in the spa's relaxation lounge chairs until you're called to your treatment room. Couples can indulge in the spa's signature 50-minute Couple's Massage, where you'll be pampered in a private couples’ room with a Swedish massage for 2, followed by glasses of complimentary wine.

Looking to turn up the heat -- literally? Book a Unity Massage, where you and your partner will learn massage techniques from certified spa therapists in a private session, using an organic "wellness candle." You'll take turns dripping warm soy wax onto each other's backs, applying and massaging it, while discovering via the spa therapist the body's primary massage points and stroking techniques. Take your new knowledge home together, for the massage gift that keeps on giving.

It's a cornucopia of couples’ treatments at the Canyon Ranch Wellness Spa in Miami. The 70,000-square-foot space may be Florida's largest spa, but seamlessly manages to create a well-heeled vibe of decadent privacy for couples indulging in their spa fantasies. The spa has devised an array of treatments incorporating ancient, traditional and modern spa therapies, like the Turkish Hammam Bath Ritual and De-Stress Chakra Ritual. Still, couples should opt for one of the divine couples-only treatments, like the Mindlink Couples Relaxation Therapy, in which duos receive side-by-side massages on paired sound tables that allow both your brainwaves to resonate to the same calming soundscape.

For something a little more, er, touchy-feely, indulge in the Ultra-Moisturizing Treatment for Two. You'll each receive a light exfoliation with a loofah scrub, followed by a relaxing body massage. Next, it's off to your private steam room where you and your partner will apply muds to each other's bodies as steam fills the room. Once the muds have infused your skin, a gentle rain will wash it from your bodies. Knowing you'll likely be all hot and bothered at this point, the spa offers you a cooling elixir to sip as a parting touch.

Imagine a remote, private island resort and spa so exclusive it can only be reached by seaplane or boat; a place where your every desire for pampering and passion is handily met. If you think such an uber-luxe getaway can only be found in the far reaches of Tahiti or the Maldives, think again. Florida's answer to those ultra-exclusive island destinations is Little Palm Island Resort & Spa, a pristine, 5.5-acre island resort where you and your partner will be transported worlds away from hustle or bustle.

When it's time to turn the rest and relaxation up a notch, guests head straight to Spa Terre, where you and your partner will be pampered together quite literally from head to toe with an assortment of couples' treatments. Guests are greeted by the spa's sleek and sexy interior that neatly incorporates traditions of East and West. Crystal chandeliers will dazzle, while the spa's Indonesian teak furnishings offer a soothing vibe. Still, you and your partner may prefer to spice things up in the spa's exterior, which features a 3-walled bathhouse with retractable roof, open in the evening -- an ideal spot to slip away for a dip, sip champagne and eye the stars. Enjoy a special spa treatment for 2, such as the Javanese Royal Treatment, an epic experience that includes a Balinese massage with jasmine-scented oil, a rice-and-turmeric skin scrub followed by an application of warm, moisturizing yogurt. You'll then shower and cap off this incredible treatment by slipping into an exotic flower petal bath.

Few American locales ooze sexy like Miami's South Beach neighborhood, and it's no wonder one of Florida's sexiest spas is located here along the steamy sands at The Setai resort. The spa is a sensual haven for guests, incorporating Southeast Asian influences into its decor and spa treatments. Couples can enjoy one of the spa's private suites, which feature ocean and pool views, as well as a private bath and private steam room for relaxing before and after treatments. The specially designed suites allow duos to enjoy side-by-side, personalized treatments, like the Ila Kundalini Back Massage, which uses a blend of essential oils, including cardamom, jasmine, patchouli and argan oil, applied through ancient massage techniques.

Still, couples seeking the ultimate sexy indulgence would do well to book one of the spa's romantic bathing ceremonies, in particular, the Setai Love Bath Ceremony. Couples will undress, and soak in a terrazzo bath in their private suite that will have been infused with a unique blend of essential oils and rose petals. The treatment includes champagne and is capped off with a treat of chocolate-covered strawberries or canapes.

The Loews Don CeSar Hotel is St. Petersburg's only 4-diamond property, and it's no surprise the hotel's spa, Spa Oceana, offers top-of-the-line service and a host of decadent treatments to guests. The spa's sexy mood is set from the moment you enter, walking through the Whisper Lounge, where you'll hear the soothing sounds of a waterfall, and sip a special mineral drink, meant to inspire balance and calm. It's then possible to slip onto the spa's rooftop garden and soak in the views of the Gulf of Mexico, or head straight to the treatment rooms -- two of which are designated deluxe couples treatment rooms, complete with 2 massage beds and bathtub.

Couples can amp up the sensuality of their spa experience with Spa Oceana's The Honeymooners package, which offers private access to a couple's suite where they'll experience a hydrating bath ritual, full-body exfoliation and therapeutic massage. But the pampering doesn't end there; the package ends with a relaxing facial. If you haven't turned into jelly after all the decadence, sashay to the spa's cafe and revel in your relaxation over cocktails.
