One of the biggest Float Mysteries in the industry is how to properly deal with condensation in a float tank. Your float tank is basically a giant humidity generating machine so clearly there’s going to be some condensation, but how much and why it forms can vary for seemingly no reason, making managing it difficult. The last thing any float center owner wants is for it to affect the floats they’re running (little water droplets falling on floaters is no fun).

Graham and Ashkahn commiserate with the industry about the difficulties in dealing with this particular hot topic, while also delving into the science of it and common solutions that should help any float center owner that’s facing this problem.

Transcription of this episode… (in case you prefer reading)

Graham: Today’s question is, “I have a bunch of water drops that keep forming on the top of my float tank. What should I do to stop that?

Ashkahn: Bummer.

Graham: So, first of all, this is really common. These things are giant humidity generating machines. So, it’s not the most surprising thing in the world that it’s forming on the ceiling there.

Ashkahn: Yeah. It happens.

Graham: The problem with this too, we should say, is not that it’s on the ceiling, it’s that mid-float you’ll get these water droplets that come down. It’s like this weird water torture where you don’t know how often or what body part it will hit.

Ashkahn: It’s pitch black.

Graham: Once every 20 minutes come down and disrupt your float.

Ashkahn: It’s pretty horrible. Once it happens, you just can’t relax anymore.

Graham: Yup.

Ashkahn: So, what causes it? What causes this condensation? What’s the condensation cause?

Graham: It’s giant humidity…? It’s a pool of water that’s kept at 94 and a half degrees.

Ashkahn: Here’s what I’m getting at: usually the condensation is either existent or especially pronounced when there’s a big temperature difference between the inside of the float tank and the outside of the float tank.

Graham: Like a soda can.

Ashkahn: Like a soda can, or like anything that holds condensation.

Graham: Like any object in the world.

Ashkahn: Various float tanks have things to try to prevent those too. From the way the ceilings are sloped to radiant heaters inside the ceilings like the Samadhi tanks have. I think some other float tanks might have that too. A lot of float tanks if they don’t have that will put a lot of insulation up at the top, things like that to all cut down on the problem. Still, if you do have a pretty serious temperature difference between the outside and the inside, which usually means colder on the outside, warmer on the inside. You’re going to get that condensation. I mean it always means that, otherwise the condensation would be on the reverse.

Graham: On the other side.

Ashkahn: When you have this situation that’s when it comes. There’s I think two big things to help deal with it. One, is humidity control. That’s part of it, is making sure that you’re trying to keep the area not extremely humid.

Graham: Even a little bit of airflow getting into the tank, hopefully not enough to disrupt the float or even be felt by the person on the inside, but just any kind of circulating air towards the top will also work to eliminate some of that condensation, which is nice.

Ashkahn: Probably the biggest thing that’s going help is keeping the room that your float tank is in warmer. Actually whatever heating system you have to heat the room, you might want to consider bumping it up a little bit and trying to equal out that temperature.

Graham: It also sometimes depends on time of year.

Ashkahn: Yeah, that’s what we find at our place.

Graham: Again with the temperature differential, winter tends to be the worse time for condensation gathering on the float tanks and causing issues. Even with kind of getting this ideal – at least with floater comfort, plus stopping condensation – interior air temperature down. We still have issues with that forming in some of our rooms and the solution we have right now is actually just checking the ceiling between every person and having basically a …

Ashkahn: Stick with a …

Graham: Rag on it. We just clean our tanks with a rag on a stick.

Ashkahn: One of those almost like a Swiffer-shaped thing.

Graham: We do that. We use a telescoping pole and go in there and get the humidity off the ceilings of the cabins just in between people. I was just talking to one of our staff yesterday and they were saying they found they have to do that in between every single float right now for one of our rooms.

Ashkahn: There’s definitely a certain mystery to it too.

Graham: Even when we have identical tanks and one room has a bunch of water forming and one doesn’t.

Ashkahn: They’re the same temperature. Sometimes I’m just like, okay there’s something going on here.

Graham: We call those … in the business we call those “float mysteries”. Get used to them – is my best advice for those.

Ashkahn: This whole conversation has sounded very logical up to this point, but in reality sometimes you’re still scratching your head. Wiping it off, I haven’t found it to be, even at worst case scenario if you’re wiping it between every float. It usually seems to do the job for the course of that float.

Graham: I love having it so the drops aren’t falling on people.

Ashkahn: Which is nice.

Graham: A couple other things to keep in mind. One is this idea of using like bubble wrap type cover for your float tanks. Oftentimes we’ll find the most condensation seems to gather when people aren’t using the float tank. Especially if you’re leaving the door closed to keep in the temperature. You want to keep the water temperature warm so you close the door to the float tank, you didn’t have a floater in there in that session, next person goes in and opens it up and it’s just drip city.

Ashkahn: Yeah, why? Why?

Graham: Because you’ve creating this contained environment. Something about humans and …

Ashkahn: Where’s the person in there? Why would the person change?

Graham: Float mystery. Don’t even try to worry about it, my friend.

Ashkahn: It matches with experience, but I don’t understand.

Graham: One thing is to leave the door to the tank opened so that doesn’t happen. You get the airflow going in, but then the water in the tank will get cool, which is where you have this combo of door opened perhaps, some kind of a bubble wrapped cover in the tank to stop heat from going up.

Ashkahn: It’s kind of like a light pool cover, I guess. We call it bubble wrap because it has a lot of bubbles on it. We’re not just like saving the bubble wrap scraps from our packaging.

Graham: Right, don’t actually just throw bubble wrap in there. Much more official than that. I promise you.

Ashkahn: They’re usually blue, kind of thick plastic. I mean you’re looking up a pool cover.

Graham: Very serious. It’s very commercial, professional.

Ashkahn: Professional business.

Graham: So, anyway, that’s one of the tricks at least when you have an empty tank in between some clients. Both keeping the water warm and stopping that massive amount of humidity from gathering on the ceiling.

Ashkahn: Yeah, you know it’s just rag-stick.

Graham: You can on some tanks, depending on the construction of the fiberglass, you could also retrofit it with a heater on the ceiling, if it didn’t come with a radiant heater.

Ashkahn: Yeah, that’s true.

Graham: Not possible on all tanks. You know, if it’s double shelled fiberglass, it’s going to be really hard to do any kind of retrofitting or anything like that. In a lot of the units it is actually possible to go back and put a radiant heater on top of the float tank – which like Ashkahn mentioned before – is how Samadhi and a few other tanks control the drips on the inside there, is actually having a heater that’ll heat the ceiling enough that it just kind of evaporates that water or stops it forming, which kind of is like the most surefire way to stop this from forming. Other than stick-rag, which obviously is without saying the best solution.

Ashkahn: Or, more insulation is a nice easy step. See if that works.

Graham: So, good luck. Good luck with the drops out there on your ceiling. Again even if you have to wipe it in between every person, the most important thing is just even if there’s humidity forming try to make sure it’s not falling on your customers. That’s where it starts to cause trouble.

Ashkahn: Okay. If you guys have more questions for us go over to floattanksolutions.com/podcast and just type them right into there.

Graham: Yup, those will go straight into our trash folder and we’ll make up our own questions from there. All right talk to you all tomorrow.

Should I Wire my Float Tanks into the Wall? – DSP 265

Ashkahn is currently recovering from his talk and the after-party last night, but Jake and Graham have gracefully taken the time to answer a construction question again today.

On the docket today is a question about wiring a float tank directly into the wall. Graham and Jake provide an overview of why some people may prefer this (it’s much easier to keep waterproof, e.g.), and why at Float On they use the twist lock for their outlets and how to properly utilize them. 

Can I Keep My Old Ceiling With My Buildout? – DSP 264

Hopefully everyone had a lovely time at the Friday Activities and the after-party.

Ashkahn is still busy running the conference, but Graham and Jake have stepped in to talk about construction!

Today the guys talk about keeping a drop ceiling or T-bar ceiling in an existing space that you’re converting to a float center. The short answer is don’t keep it, as it can cause problems, but the guys do have some workarounds if your landlord is opposed to changing the ceiling. 

What to Expect When Expanding from 1 to 3 Tanks? – DSP 263

Ashkahn is busy preparing for everything that happens tonight and tomorrow for the Conference, but that doesn’t mean Daily Solutions will stop being daily. 

Graham and Jake talk construction and what to expect when you’re expecting… a giant expansion for your float center. What’s it look like when you go from one tank to three? How do the demands change? What needs to be put in place to make sure that you’re not hitting snags? 

Fortunately, these guys know the score and are happy to share. 

All About Floor Drains – DSP 262

As Ashkahn gets everything ready for the Start a Center Workshop (happening today) and the Float Conference this weekend, Graham and Jake tackle answering construction questions on the podcast. 

Today they’re talking about floor drains. What to consider for drains and how they might pair with different types of flooring. Given the hefty price tag for these more advanced drains, having as much research before making a decision on these is essential. Luckily, the guys have done the hard part already and identified a lot of things to consider. 

How to Deal with Float Room Humidity – DSP 261

Graham and Jake are at the helm again while Ashkahn puts the finishing touches on the Float Conference. 

Today, the guys are talking all about humidity and how to deal with it when constructing your float rooms. They talk about all the little nuances that you (or your contractor) might not think about when it comes to humidity and how soundproofing and regular airflow may not always go hand in hand.

Alberta is often called the Texas of Canada. Part large oil industry, part cattle country.

Don’t Mess With Alberta!

At the base of the Rocky Mountains, replete with an Olympic Stadium, Calgary is a world-class destination for winter sports. The float community developed here similarly to Edmonton – there wasn’t anything nearby except for one or two residential float tanks, and then, in a short period of time, several centers opened all at once. Instead of competing, they’ve decided to work together and have developed one of the tightest knit float communities we’ve seen. They even have monthly Float Dinners, much like we do with the float centers in Portland. They don’t keep meeting minutes, so it’s hard to determine what they talk about at these dinners; my guess would be salt, the effects of salt on various substances, and how salty salt damage can make someone salty.

After Montana, we blazed our way back into Canada. The drive was long, but the scenery was beautiful. We followed the Rockies north, driving up to Edmonton. It’s a bit of a detour but, there are so many float centers in Edmonton, it seemed crazy not to stop by.

The city itself is primarily made up of workers from the oil fields – high risk, high income jobs that fuel the economy. At least until recently. Our visit was right in the middle of the Fort McMurray wildfire which has displaced a lot of the workforce, forcing 100,000 people to leave their homes. Many came to Edmonton, being the nearest metropolitan area to Fort McMurray. Some already split their time between the two cities, living in Edmonton and traveling to Fort McMurray for weeks or months at a time for work.

It’s understood that, in economic hardship, luxury commodities are typically the first thing people cut back on. Surprisingly, this doesn’t seem to be the case for floating. In fact, more people seem to be trying it to help alleviate the stress, many centers even offering free or discounted services to those displaced in an effort to help in a small way.

We’ve got two more stops in Colorado Springs before heading west. It’s a town known for its military base and long history of weapons testing. With such a large military presence, it comes as no surprise that the float center owners here are veterans, themselves.

After that, we shoot across to Salt Lake City. Utah is filled with gorgeous sights, from breathtaking lakes to stunning painted hills. With an international landmark famous for its effects on buoyancy, Salt Lake City should be pretty familiar with the concept of floating. With five different float centers, and the manufacturer of the Zen Tent out there, there could be some cause and effect.

After that, we head up into Idaho and Montana to close out the Central United States portion of our Tour. We’ll follow the Rocky Mountains north, taking in the scenery along the way.

Denver has been home to a vibrant float community for a long time. Some of the earliest commercial centers that started up in the ‘70s and ‘80s were out here. 30 years is a long time, and most of the old centers aren’t around anymore, but there’s a conscious community that has been floating since the old days and they love how much the industry has evolved and grown.
