As a cruise ship begins to sail away, the only thing more satisfying than waving goodbye to your routine life is completely forgetting the stresses of everyday life while poolside at the ship's spa. Cruises have refined and partnered with some of the best spas to set land-bound facilities afloat. Thanks to spa-inspired and curated cabins and staterooms, spa lovers can now relax for the entirety of their trip. Here are the most relaxing cruises for spa lovers.

Canyon Ranch Goes to Sea

For those unfamiliar with Canyon Ranch, this network of spas includes three locations in Massachusetts, Arizona and Nevada. While most locations are entire wellness resorts, the Canyon Ranch spa and fitness centers located onboard Celebrity Solstice ships, Cunard ships, Oceania ships and Regent Seven Seas cruises elevate luxurious relaxation to an all-encompassing experience. Bringing a facility that could easily be found on land to the high seas ensures that not only the treatments are high-quality, but that the saunas, heated tile loungers, gardens and tropical rain showers create a full, calming day at the spa. The company has even partnered with Celebrity to bring guests additional perks like another class of cabins with spa-level products and linens as well as health food restaurants.

Crystal Life Spa & Salon

Climb on Crystal's Symphony or Serenity ships to find the Life Spa and Salon designed to fully embrace feng shui. The clean design quickly ferries guests away from their stressors and into a meditation-like trance. The crowning feature of this luxurious spa is a treatment bed entirely made of quartz crystal to help reduce muscle tension while increasing relaxation. Treatment options range from salt scrubs and massages to treatments like Botox. With separate male and female sauna facilities, find balance and harmony while slipping away from everything.

LivNordic Spa by Viking Cruises

A long-standing favorite among cruise-goers, Viking Cruises' Ocean vessels feature LivNordic Spa, a renowned spa known for its stunning facilities operated by Raison d'Etre, based in Oslo. Following Nordic tradition, the spa offers its guests a range of hot and cold rooms and pools, which stimulates the circulatory system by shocking it. Visit the snow grotto and proceed to jump into the hot tub, but use caution. The stunning minimalist design is tranquil, setting a serene atmosphere for post-treatment relaxation.

Vitality Spa on Royal Caribbean Oasis Ships

Royal Caribbean's Oasis ships feature rambling spa and fitness facilities outfitted with more than 24 treatment rooms – fitting for the company's largest ships at sea. Complete with steam rooms, heated tile loungers, relaxation rooms and other standard spa features, their treatments run the gamut from reflexology and facials to medical spa treatments like Botox and acupuncture. Guests looking to sweat it out in a gym session or group fitness classes with ocean views first will love the many options to choose from at the expansive fitness center. Parents traveling with teens can also treat them to an age-appropriate and safe facial, pedicure or massage appointment in one of three YSpa treatment rooms geared to those between the ages of 13 and 17.

Greenhouse Spa Onboard Holland America Line

Holland America Line offers one of the most spacious spas onboard a ship, and thanks to their day pass option, booking a full itinerary of treatments is not necessary to take advantage of the facility. Relax in a thalassotherapy pool (one that uses seawater) with extra-strong jets to massage sore muscles and melt away tension, or visit the steam and aromatherapy center. Soak in pools infused with essential oils to hydrate skin and breathe deep to be set at ease. Hit the gym with state-of-the-art equipment, go for a swim in one of the two outdoor pools or unwind in the hot tub. The spa-quality experience doesn't have to end on the massage table, however. Book a Greenhouse Spa & Salon stateroom to continue the peace and quiet between visit to the saunas or treatment rooms.
