Float Therapy San Antonio

Enjoy a Float Pod Session In One Of Our Cutting-Edge Tanks Today!

A float tank, also known as a sensory deprivation or isolation cabin, is filled with a super concentration of Epsom salt, allowing you to float easily and effortlessly on the water’s surface.  Floatation therapy frees you from the effects of gravity, your body is weightless – joints and muscles can truly relax, all tension melts away. No longer needing to process sensory input, your brain and nervous system begin to fall into a deep, meditative state.

Each floating session ranges from 30–90 minutes long. Once you are in the float cabin, you’ll hear the sound of waves, as well as see colored lights. Then, all sound and lights are eliminated, and you float into deep relaxation. At the end of the session, gentle sound and light effects are reintroduced to let you know the session is ending.

Krysus is the first human performance and recovery center in San Antonio featuring our unique ultra-hygienic cabin in a float spa setting. Before and after each floating session, 100% of the water is filtered and disinfected automatically, and the emptied cabin is disinfected by hand, making it ready for your float.

What is float therapy?

Float therapy is a method that uses a specially-designed sensory deprivation tank to achieve a unique isolation experience.  This stress-free, sensory deprivation experience helps our patients address both physical and non-physical trauma.


Many people consider floating to be effective in obtaining different health benefits and mental benefits.  Over the past few years, floating has become much more popular. Read the Top 21 benefits of floating.

Float therapy on the Dead Sea

History of Float Therapy

Floating on highly salt-saturated water is not new – thousands of visitors travel to the famous Dead Sea between Israel and Jordan seeking medical treatment and relaxation. Our float cabins offer the same salinity and buoyancy right here in San Antonio. A Krysus isolation cabin contains about 2/3 of water and 1/3 of pure Epsom salt – roughly 850 pounds of salt, ten times as salty as the ocean!

Many of us are deficient in magnesium, an important mineral that supports bone and nervous system health. Symptoms of low magnesium include fatigue and muscle cramps, and if untreated, can lead to serious medical complications. While it’s important to include plenty of magnesium-rich foods in your diet, absorbing the magnesium sulfate (Epsom salt) found in the float cabin will help increase your levels, detoxifying the body.

How does Floating Work?

The float pod experience in San Antonio starts with attaining a water temperature of 93.5 degrees Fahrenheit, the average external temperature of the body. This means the mind does not distinguish between where the body ends and the water begins, a level of tactile sensory deprivation that is nearly impossible to replicate. As you float, pain and tension fall away, positive endorphins are released, and stress hormone levels drop.

While the benefits of floatation therapy for pain relief, injury recovery, muscle and joint soreness, and stress are clear, studies are ongoing exploring the effects of gravity reduction (floating) and sensory deprivation on a wide variety of conditions. Patients with fibromyalgia, a debilitating condition with few remedies, have reported reduced pain both during a session and over the course of a series of sessions. Sensory deprivation can also be a huge relief to people with autism, since a difficulty filtering and processing sensory information is a major symptom.

Enjoy The Benefits of Float Therapy

One of the most exciting applications of float therapy in San Antonio, and a particular focus at Krysus, is in treating PTSD (post-traumatic stress disorder). Through gravity reduction and sensory deprivation within our cutting-edge float tanks, patients suffering from PTSD and other trauma-induced disorders can work through emotionally painful experiences without triggering a new wave of stress. The production of dopamine and decrease in cortisol help send the body a signal of safety and calmness. This can be life-changing for military veterans, those in tactical occupations, and other communities prone to traumatic stress.

Interestingly, EEG readings taken in studies on sensory deprivation, such as experienced in float cabins, have revealed an increased synchronicity of brainwave frequencies between our left and right hemispheres. Float therapy has the potential to enhance our problem solving and cognitive abilities, as well as our creativity. Anecdotal evidence abounds of creative breakthroughs, both in technical skill and inspiration, after a series of float sessions.

A float pod session is also the perfect spa-like environment in San Antonio to learn new information. There are no distractions from the body or external stimuli, setting the mind up to absorb information more deeply and retain it more completely. Students have used the deep “theta” state of relaxation produced in the isolation cabin to enhance memorization and language learning, as well as support hypnosis and visualization techniques.

Whatever your reason, once you experience floatation therapy, you will want to make floating in our tanks a regular part of your health, wellness, and performance regimen.

Have Questions About Floating in San Antonio?

Frequently Asked Questions

Floating is all about achieving a relaxed state. Avoiding or reducing things that increase nervousness or anxiety will help improve your float experience.

Try to avoid or reduce caffeine, alcohol and drug intake in the 24 hours leading up to your float.

Eat a light meal 60 – 90 minutes prior to floating.

Avoid shaving or waxing as freshly shaved skin can lead to irritation.

Floating is a unique and refreshing experience with several benefits including de-stressing and pain relief.  There are at least 21 benefits to floating.

We recommend arriving 10-15 minutes prior to your float start time.

Our staff will take you to your prep room to change into a robe and slippers. Once changed, you will be escorted to your float room. Each room is equipped with its own float tank and shower for your privacy.

You’ll start your float by showering, prior to entering the pod. Then, you’ll enter the tank in privacy. You may either close the lid or opt to leave it open if you are claustrophobic.

Once in the tank, simply lay still, relax and float. After exiting, you’ll shower once more to remove the salt and head to your prep room to re-dress.

Nothing but yourself! We provide everything you need for your float (towels, robes, earplugs, body wash/shampoo…)

Each float room is completely private. We recommend that you float nude, but you are welcome to bring a swimsuit if it makes you feel more comfortable.

Wear something that is comfortable and easy to change in and out of after a float at our facility.

You can wear a bathing suit during your float, but often times our customers float nude. For some customers, wearing clothing can be a distraction from the float experience. Ultimately, what you wear is based on your personal comfort level.

Each float tank is in a private room with a private shower.

There are very limited side effects to floating. The most common after a float is irritated skin, especially for customers with freshly shaved/waxed skin or open cuts. Most floaters do not experience nausea or motion sickness, but on occasion some customers who are already prone to suffer from motion sickness may have this reaction to floating.

Float tanks are filled with such a high concentration of salt that the body automatically floats with no effort. Many customers achieve such a state of relaxation that they fall asleep while floating.

However, being under the influence of drugs, alcohol and/or medications with a sedative effect will increase the risk of drowning during a float. People with uncontrolled disorders that may cause them to lose consciousness at any moment could also be at risk of drowning during a float.

See “Who should avoid float therapy?” below.

Customers with the following should re-consider scheduling their float sessions:

  • Those with incontinence not medically controlled
  • Those with kidney or respiratory infections
  • Those with infectious disease or contagious skin conditions
  • Those with injuries or open cuts/wounds
  • Those under the influence of alcohol or drugs
  • Those with dementia or Alzheimer’s not medically cleared
  • Those with low or high blood pressure not medically cleared
  • Those with diabetes not medically cleared
  • Those who’ve received chemotherapy within the last 30 days and not medically
  • Those who take medication(s) which magnesium from Epsom Salt can have
    interactions with (e.g., certain antibiotics and muscle relaxants)
  • Those with a condition which may be adversely affected by cutaneous absorption of magnesium
  • Those experiencing a heavy menstrual period or external vaginal issues that
    cannot be managed with a tampon or feminine cup
  • Those with a history of heart trouble, schizophrenia, epilepsy, seizures or blackouts not medically cleared
  • Those who’ve had any type of hair color/treatment within the last 14 days
  • Those who’ve recently spray tanned where it is still easily washing off
  • Those who’ve recently gotten a tattoo (less than 4 weeks old)

With a little preparation you can float without worrying about your hair.  Here’s everything you need to know about floating and hair color before scheduling your session.

Floating is incredibly safe for the majority of the population, but rare negative side effects can happen like restlessness and nausea.   

We offer 30-minute and 60-minute float sessions. You won’t be in the water the entire time, though. We recommend arriving ten minutes before your session to check in and prepare. You’ll spend the first few minutes changing, going to your private room, showering, and settling in. You’ll also shower after the float. All in all, you can expect to be in the water, floating, for 20 minutes out of a 30-minute session and 45 minutes out of a 60-minute session.


You’ll be inside a small tank for an extended period of time, so we don’t recommend floating if you have moderate or severe claustrophobia. However, some people with mild claustrophobia enjoy floating! Proper preparation and coping strategies make it possible to overcome mild claustrophobic tendencies before a float, but this differs from person to person. While you’re always free to exit the float tank if you feel uncomfortable, we recommend chatting with a mental health professional before floating to make sure it’s a fit for your situation.

Krysus HP float tanks contain over 1,000 pounds of Epsom salts. This makes your body float in the water, but it also has added benefits. Epsom salt contains magnesium, which helps with muscle relaxation and pain relief. Some people say their skin feels softer after a float, although we don’t recommend floating with open cuts or wounds. Others say the Epsom salt has mental benefits like improved sleep and lower anxiety.

Krysus is the first San Antonio float tank center to follow careful hygiene practices and keep our water impeccably clean.

We ask all floaters to shower before entering the tanks, significantly reducing the amount of oils, sweat, and other contaminants introduced into the water. All of our water goes through a high-efficiency filtration system between floaters. It removes impurities, hair, and other small particles in the water tanks. While the high concentration of Epsom salt is a natural disinfectant, we also use chemical sanitizers to kill bacteria and viruses.

With that said, we also change the water regularly, skim the water surface, and disinfect the tanks manually between every session.

Yes, it’s common for people to fall asleep in the float tanks. It’s generally safe because the Epsom salt in the water makes you highly buoyant, so you float effortlessly. This buoyancy makes it almost impossible to turn over in the tank, significantly reducing the risk of drowning. At ten to 12 inches deep, the water is actually pretty shallow. Krysus also provides float pillows that will keep you right-side-up as you float.

However, we don’t recommend float therapy if you have seizures or other medical conditions that could cause you to completely lose consciousness inside the float tank.

Usually! Many pregnant women find that floating reduces pressure on joints and improves circulation. Others find that the Epsom salt in the water works wonders for their anxiety and depression. However, you do need to be able to get in and out of the float tank without assistance during all three trimesters. We don’t recommend floating after 37 weeks of pregnancy because there’s always the risk of your water breaking while in the tanks.

Yes. Anyone under the age of 18 must have written authorization from a parent or legal guardian. If someone is 14 to 18 years old, they must have a chaperone in the facility, like the waiting room, while they receive services. Children under the age of 14 must have their parent or guardian physically with them in the room at all times.

Absolutely! Nobody wants to float hungry, after all. However, we recommend sticking with light snacks and drinks before a float. Some people feel nauseous floating on the highly buoyant water, especially during their first session. It’s also a good idea to avoid large doses of caffeine or alcoholic drinks before you float.

It depends on your schedule and individual preference, but most people see the best results when they float once or twice a week.

Floating can’t cure or treat any disease, but many Krysus HP customers find floating helps manage the symptoms of arthritis, insomnia, migraines, back pain, anxiety, and depression. This is because of the soothing experience of floating in a gravity-free environment, plus the healing properties of the Epsom salt in the water.

Yes! We ask everyone to shower before and after their float session. This keeps the float tank water nice and clean. It also removes excess salt from your hair and skin after a float session, reducing the odds of skin irritation.

Yes, as long as it isn’t a recent tattoo. Getting a tattoo breaks the skin’s surface, so floating could irritate your skin and increase your risk of infection. It takes about four weeks for a fresh tattoo to heal, so it’s best to wait at least a month before floating. When in doubt, ask your tattoo artist or dermatologist for their opinion.

The water in Krysus float tanks is around ten to 12 inches deep. It’s just deep enough to give you the sensation of weightless floating, but shallow enough that it’s easy to enter and exit the tank.

Absolutely! Our float tanks will quietly play music when you settle into the tank and when it’s time to end your session. You can float in dark silence or choose to turn on the float pod lights and music. You can listen to the pre-downloaded sounds on the pod, which are designed to help you relax and enjoy your session.

Saltwater can sting if it gets into your eyes. If that happens, use the towel provided by Krysus to gently wipe your eyes. You can also exit the pod to rinse your eyes in the shower.

We also provide swim caps and earplugs to prevent water from entering your ears. If you get water in your ears and it becomes uncomfortable, you can often get rid of it by tilting your head to the side and gently pulling on the earlobe to open the ear canal. If that doesn’t work, use over-the-counter ear drops to evaporate the water trapped in your ear.

Probably! Many people with arthritis find float therapy helpful for alleviating pressure on inflamed joints. That said, you need to be able to enter and exit the float tank independently. If you struggle to move independently, it’s best to consult a doctor before trying float therapy.

Yes. The high Epsom salt content in the water helps to relieve muscle soreness and stiffness. This can be particularly beneficial after intense workouts or competitions. Try floating the day after an intense workout when you’re good and sore for the best results. Athletes also reap mental benefits from float therapy, claiming they feel more focused, alert, and well-rested after a session.

It’s easy! Visit the Krysus booking page and specify how many people you want to book for. Select “Float Therapy” from the menu options and choose between a 30-minute or 60-minute session. Specify a room preference, if you have one, and a date and time. You’ll need to create an account to manage the booking. Once you log in, the system will approve your booking.

If you have questions, you can also book over the phone at (210)-600-4093, and our friendly staff will be happy to help.

All of the float tanks at Krysus are identical. We have four private float therapy rooms available for booking, but you can specify a specific room during booking if you prefer.

Some services, like salt therapy, can accommodate four people at a time. However, floating is designed to be a solitary experience with as few distractions as possible. You and another person can certainly visit Krysus at the same time, but you’ll each have a private float tank room and won’t be able to share tanks. If you’re scheduling for multiple people, call us at 210-600-4093 for help with booking.

Float therapy is just as much about mental benefits as your physical health. It’s easy for your mind to wander in a sensory deprivation tank, especially if you haven’t tried it before. Mental preparation is key.

Before your session, take some time to think about what you hope to achieve during your time in the tanks. This could be relaxation, meditation, problem-solving, creative thinking, or simply experiencing something new. Deep, slow breathing can calm your mind and body. Practicing breathing exercises before your session can make it easier to relax once you’re in the tank. If you already practice mindfulness or meditation, consider doing a short session before floating. This can help put you in a receptive and relaxed state of mind.

If you’re feeling anxious about your float, check out our Learning Center for a better idea of what to expect before your first session.
