Something in the world of floating have you stumped?
Show Highlights
Graham goes solo today while awaiting Ashkahn’s return.
Graham takes a question about cement backer board and the reasons it should be avoided in a float room. It’s a dense episode. Real dense. More dense, in fact, than cement backer board.

Transcription of this episode… (in case you prefer reading)
Graham: All right, hello, everybody. My name is Graham, and that’s it, my name’s Graham. There’s no one else in the studio here with me today. Ashkahn’s gonna be back very shortly, and we’ll have the old Grashkamn duo.
But, for now, I’m just gonna launch right into answering today’s question, which is: “You mentioned not to use cement board when using tiles on the wall. What is the reason for that?”
There’s a couple good reasons, besides just we said so. They are related to soundproofing, and then salt, I guess, like so much else in the float world. The salt aspect, I guess we’ll talk about first because that’s more core to what cement backerboard is.
Basically, just in case you’re not familiar with it, it’s a different kind of material that you’re putting behind typical tile wall. It’s kind of porous, but still very dense, kind of inflexible type material. Typically, you’d put this directly on the studs rather than putting on drywall or something on top of them.
The kind of classic application is that the tile going on top is itself kind of permeable, especially the grout. For instance, in a shower area, you expect a certain amount of the water to kind of seep into the grout, and perhaps get into whatever’s behind it. If that’s regular drywall, then you risk it getting that wet, and molding out, and stuff like that. You want this kind of material back there that’s more solid, that’s not going to mold, but that’s also semipermeable so when the water gets in there, it’s allowed to evaporate over time, which is kind of the idea.
With our application, we’re using porcelain tile with epoxy grout, so we’re not really expecting water to get back there. The main protection from the walls is actually just that impermeable surface of the tile and the epoxy grout.
The other thing is, if water did get back in there, and if you weren’t using kind of a permeable solution with the cement backerboard, salt would also theoretically be able to get back there. That’s terrible because while water is able to evaporate, saltwater will get into something, and when it dries, the salt crystals will expand, and that thing will just start to get destroyed, which is where so much of the salt damage that we see in our space comes from. That’s kind of just on the salt-proofing side, why you don’t really see that cement backerboard.
The main reason why you see the alternative, which is some kind of either adapted drywall setup, usually MMR, mold and mildew resistant, maybe multilayered for soundproofing, or specifically soundproof drywall, something like QuietRock, also maybe MMR, mold and mildew resistant. The idea with that is in addition to trying to make these wet rooms, which is usually where cement board is going, you’re now trying to soundproof those, and turn them into the equivalent of a sound studio almost. Cement backerboard is not going to provide you the same kind of soundproofing as a really heavy drywall set up, or especially something like QuietRock.
Since you want that soundproofing, is also one of the reasons that we go with a totally impermeable surface on the outside. Other than saltwater, you just wanna make sure that now that you’ve put up this heavy soundproof drywall, you’re protecting it. So kind of for both of those reasons, and they mix together a lot, but that’s typically why you’re not seeing cement backerboard in a float center type application. Instead, what you will see, if you are using tile, is this heavy layer of soundproof drywall, again, whatever, whether it’s custom made or just multilayers of drywall with something like green glue in between. Then you’ll see the porcelain tile on top of that.
All right, that wasn’t so bad. I think that the Graham only show can hold its own, maybe we’ll just kick Ashkahn off for the foreseeable future, you know, just kind of wing it on my own.
If you do not wanna see that, let me know by going to floattanksolutions.com/podcast and I will talk to you tomorrow. Thanks, everyone.

Should Float Centers use Light or Heavy Gauge Studs? – DSP 269
Still no Ashkahn today. He’s taking a couple of post-conference days to himself.
Jake and Graham are on the scene though to answer construction questions, though. Even the straight forward ones, like today. Jake informs us which to choose when doing construction, light or heavy gauge studs when constructing a float center, while getting a little sidetracked when comparing wooden and metal studs.
Construction to Make Your Life Easier – DSP 268
Graham and Jake cover a wide range of construction tips to make running a float center easier. Everything from making sure you have extra storage to installing mop closets with sinks in them for dealing with heavy duty chemicals.
The advice is pretty much a shotgun approach of tips, tricks, and hard lessons learned throughout the years.
Draining Float Tanks into Septic Systems – DSP 267
Graham and Jake tackle the difficulties of draining float tanks and how that process can differ based on different municipalities, different water treatment systems, or whether you’re using a septic system or not.
Water treatment typically involves whole contained ecosystems and highly concentrated epsom salt water can impact that pretty drastically. The guys provide good tips for each type of system and what to be prepared for if you’re operating in a rural area with a septic system.
The Difference Between STC and Decibels – DSP 266
Post-Conference Ashkahn is still out of the recording studio, but fortunately Jake is keeping Graham company in there.
Graham and Jake break down the differences between decibels and STC ratings, two very important to understand when figuring out soundproofing. There’s a lot to digest in this episode, but fortunately the guys keep it easy to understand by providing a broad level overview of the different concepts.
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.

Home sweet home! After so many months on the road, it was strange being back here in Portland. We were exhausted, excited, and a little travel weary. The first night back, I slept in my own bed for the first time in three months and the world just melted away.
Having travelled across the United States, I’m reminded of how insular Portland is. We are aggressively fixated on keeping things local. Local beer, ketchup, bikes, pet food, pillows, phone cases… it’s part of our charm. We want to reward people for living here and being a part of the community. It’s so pervasive that, after living here for so long, I kind of forgot that Secret Aardvark hot-sauce isn’t available everywhere, and that most cities don’t even recycle, let alone compost.

Our northern neighbor – a sister city, of sorts – Seattle is the largest metropolitan area in the Pacific Northwest. It’s the land of Microsoft and Kurt Cobain, and the culture here embraces both simultaneously. It’s tech business professional in the front and rock n’ roll grunge in the back. This blend creates a perfect storm of high energy business life and high energy nightlife, making relaxation a valuable commodity. Floating helps fill the void left by nightmarish traffic and overcrowded restaurants.
Given that it’s so close to home, the float centers in Seattle are a lot more familiar to us. Our visits here were more like a high school reunion than they were like the first day of school. During some of our visits, we were picking up conversations right where we left them.

Vancouver is the largest metropolitan area in Canada, and third largest on the West Coast. It’s a major hub for international trade, with one of the largest ports in the world, giving it a large migrant population, mainly from Asia, the Middle East, and Australia. It’s also been a long-time home to the Canadian film industry, and has even been nicknamed “North Hollywood.” Dozens of film and television productions from major studios film here every year.
Vancouver is very much an international city. It has large boroughs dedicated to varying cultures, including one of the largest Chinatowns in the world. The society here is more receptive to new ideas, always looking for the next big thing; it’s not surprising that floating has blown up in Vancouver as much as it has.
In the last 3 years, 10 float centers have opened up, most of them being larger 4–6 tank centers. The really interesting thing is how they all opened within the same short amount of time about 1 ½ to 2 years ago, within months of each other.

We finally made it back to the West Coast! We went through the Canadian Rockies and were overwhelmed by the beauty of it all. We drove through hours and hours of winding mountain roads, fertile valleys, and tiny towns so picturesque they looked like movie sets. It was so captivating, in fact, I suspect Graham and Ashkahn may have secretly replaced themselves with robotic doppelgängers to hike throughout Banff.
This post will focus on the smaller communities in B.C. that are bringing floating to new people every day. We also get to visit Canadian manufacturer Pro Float. They’re relatively new to the scene, just opening up earlier this year – another exciting sign of the growth in the industry.
