How much Epsom Salt is needed for initial setup?
800 lbs. (363kg) is needed for the initial setup whether you purchase the tent or tank. We recommend buying an additional 50-100 lbs. for maintenance over a year. To make it easy, we sell pallets of float tank epsom salt on our website here. 

 

Do you sell the Tank and Epsom Salt together in one package?
Yes. For customers in the lower 48 United States we offer a Float Tent Ready Package and Float Tank Ready Package that includes one complete Tank/Tent, Epsom salt for the first year, Shipping & Handling to anywhere in the lower 48 United States, plus extras to get you started.

Our Float Tent and Float Tank can also be purchased individually by itself in on our Online Shop and can be shipped anywhere in the US or Worldwide! 

What Grade of Epsom Salt Could I Use? Is Agricultural Grade Okay?
We prefer and sell pharmaceutical grade Epsom salt as it’s more refined (e.g. cleaner without grit) and generally more pure. That said, you can use agricultural grade Epsom salt and that is often the only salt some of our customers can locate in their area. With agricultural grade you may end up with grit in the tank and would need to clean that out, which isn't easy but may be worth the savings. You would also want to look at the chemical makeup to ensure there's not any additional, harmful additives or chemicals in the salt that you would not want to be floating in.

Could I Use Table Salt, Ocean Water or Water Softener Salt?
You could, but we think it’s a really bad idea... MgS04 (Epsom salt) and NaCl (ocean, table, & water softener salt) are not the same thing. You can’t filter the biome out of ocean water before you fill the tank, and NaCl brine is likely to pickle you while you float AND destroy the tank structure and components. But hey, it’s your tank to do with as you please - just don’t ask Zen to warranty it.

How do you heat and maintain heat in the Zen Float Tent and Zen Float Tank?
Included with your purchase are two radiant heating pads that can always be left on to maintain the temperature of the water in between and during floats.  For more information please read this post about our radiant heating design here

How often does the salt need to be changed?
If maintained properly, the water and salt solution should last you anywhere from 1-2 years or longer.  

How do you drain the Zen Float Tent and Zen Float Tank?
Get buckets, get some friends and start a bucket brigade - 200 gallons, 5 gallon buckets, 40-ish bucket-loads and you’re done! OR, you could invest $80 in a sump pump and be done within 20 minutes. Click here for the pump we recommend.

What is the liquid capacity of the Zen Float Tent and Zen Float Tank?
Approximately 201 gallons (760 litres) if filled 10” (25cm) high.

What is the weight of a Zen Float Tank/Zen Float Tent once filled?
Approximately 2200 lbs. (998kg)

Can a Tank or Tent be used on an upper-level?
Both the Tent and Tank were designed to meet most US building codes and are similar in weight to a waterbed. However, you need to confirm that your floor load-bearing capacities are able to support the Float Tent or Tank weight when filled and occupied by contacting a registered structural engineer. They’ll need to calculate at approximately 50 lbs per square foot + body weight.

Does water leak when you enter/exit the tank?
No, water doesn’t leak from the unit, but when you get out, your body will be wet, like getting out of a shower, so a bath mat is a great idea. There may be condensation on the inside of the door when you open it, but thanks to the steep walls of the pyramid design, most will run into the tank.

Are your tanks sound proof?
When designing our tanks we really focused on a light-weight, thin walled design so it would be affordable, shippable, and easy to move. Keep in mind, even the most expensive float tanks don’t eliminate sound, they only reduce it. You’ve got to have a quiet setting if you want to float at home. Read more about what goes into creating the perform home floating environment here. 

How do you know when you have enough salt in the water?
The best way is to use a Hydrometer which is included with the purchase of your Zen Float Tent or Tank. Salt is added until specific gravity is between 1.23 and 1.3, which is indicated by an easy to recognize “Float Zone” marker on Zen hydrometers.  More information about this can be found here. 

What about water maintenance?
We have designed the UV filter to take care of majority of the maintenance of the water. You can also find a copy of our water care guide and videos here

Does the filter and heating pad need to be running at all times?
We recommend leaving the heating pads running at all times to properly maintain water temperature and quality.  Your filter should also remain running at all times and should only be turned off while you are in a float session.  

What is the warranty on the Zen Float Tank?
We want you to trust that anything you buy from us, we will stand behind. That is why we have a 5-Year Warranty on all manufacturer defects on our Version 2 Tank structure. If we make a mistake in manufacturing, we'll replace it every time.

Mechanical parts are a little different, as there is a natural wear and tear like any machine and we can't say it will last forever. We can say, however, that we will replace any mechanical part that is faulty for one full year. It's our promise to our customers that anything they buy from us is made to last.

What is the warranty on the Zen Float Tent and Version 1 Tank?
There is a 1-year warranty on all manufacturer defects that occur in the structure – If we make a mistake in manufacturing, we'll make it right. Same goes for the mechanical parts, we will replace any mechanical part that is faulty for one full year.

Is the warranty transferable if I sell my tent or buy a used float tent?
No, the warranty is not transferable and only applies to the original float solution (Tank or Tent) owner. 

Where can I buy replacement parts?
All the parts included with the tent such as the filter and heating pad are designed to last. Other replacement parts such as filter bags, vent caps, etc are available for purchase in our online shop at an affordable price.  

Are there patents covering the Zen Float Tent and Zen Float Tank?
Yes we have submitted and we are currently patent pending for both float solutions.

Is the material BPA free?
Our Tents are BPA free and the materials are lab tested and certified (more info here). We have not, yet, had the Tank materials undergo the same lab work and we do not know if or claim they are BPA free.

Can the Zen Float Tent and Zen Float Tank also be used for commercial purposes?
To be clear, the Zen Float Tanks and Tents were not designed for commercial use and we have not tested them for that use. Any use in commercial applications instantly voids all warranty coverage Zen provides for the structures and the components (heating and filtering). If any issues were to arise with the structure or the components you would need to pay retail prices to replace any damaged part.

That said, we have sold the Zen Float Tank to people that are using them in commercial applications including float centers, retreats, spas, and athletic recovery. The Tanks have done very well for them, and they've saved sizable amounts over purchasing traditional commercial float pods. Some have had to replace pumps due to misuse, but report that these costs are still far lower than maintaining a pod. As you know, it would take replacing a whole, complete Float Tank four times to equal the same cost as one of the lower-priced commercial float pods.

There are things to think about while deciding on commercial use of our Tanks, which we cannot provide support for. Most importantly you'll need to know what your local health code laws are and if you can follow them. You'll also want to consider that the filtration in our Tanks takes about 45 minutes to circulate the water 3 times, this is about a third slower than most commercial systems, so you'll need to allow that amount of time between floats.

As far as differences between the Zen Tank and the commercial pods, there are many:

  • Commercial pods are normally made of rigid fiberglass and are bulky to ship; the Zen Tank is inflatable paddle board material that becomes rigid after inflation and ships easily in the two medium-size boxes.

  • Commercial pods made of fiberglass require float rooms to be built that have plumbing, sound-deadening, and are mostly light-proof; the Zen Tank does not require plumbing because it is self-contained, it also already provides sound-deadening and light-blocking due to the two-layer walls that have 2 inches (5cm) of insulating air in them.

  • Commercial pods generally have commercial level filtration that is able to filter the water 3 times in 15 minutes allowing for quick intervals between floats, they normally self-dose the water with cleaning chemicals like ozone or H2O2 and the filtration can be remotely controlled; Zen Tanks take three times as long to cycle the water during after a float, the H2O2 must be added manually and you would need to create your own solution for remotely controlling the filtration.

  • Commercial pods can be optioned with lights, sound, and other additions; you would need to add these things to the Zen Tank as we do not offer options.

  • Commercial pods heat the water externally and require it to be cycled for reheating which limits the length of a float to around 1.5 hours; Zen Tanks have always-on radiant heating that allows floats to go as long as you'd like without the water getting cold or needing to be circulated.
