The world hasn't gotten any quieter since your last float. If the stress has crept back in, the sleep has slipped, or the body's tightened up again — the tank is right where you left it.
Both are here at 515 Medford Street now. Jump straight to the one you came for.
Our XL Dream Pod is one of the only couples tanks in the Boston area — two people, one hour, no phones, no talking required. It's the rare thing you can do side by side and still come out feeling like you got time to yourself.
Good for date night, anniversaries, or dragging a friend along who's never floated. Plenty of people book it just to have the extra room.
Nobody stops floating because it stopped working. It's always the same thing — a stretch of long weeks, a full calendar, and the one hour that was just for you quietly falls off the list.
Here's the part worth remembering: the calm you felt walking out of the tank wasn't a one-time thing. It's a baseline you can get back to. And it usually only takes one float to feel it return.
You already know how it feels. Here's what's actually happening — and why a single float still does the work.
Stress compounds. Weeks of being switched-on keep your body braced without you noticing. An hour with no light, no sound, and no gravity pulls the nervous system out of fight-or-flight and back to baseline — the reset you can't get from your couch.
The deep sleep floating gives you fades when you stop. Many people float specifically to break a bad stretch — the magnesium, the full-body decompression, and the calm afterward tend to show up that same night.
900 lbs of Epsom salt takes every pound of gravity off your spine and joints for a full hour. For chronic pain, tight backs, and old injuries, that decompression is the relief that's hard to find anywhere else.
If you're back to training hard, your body is carrying the load. Floating flushes tension, speeds recovery, and gives your muscles an hour of true zero-load rest — so the next session feels better than the last.
A lot of people try one float and never get around to the beginner 3-pack — the first-timer deal that gets you three floats at $50 each instead of $75.
If that's you, it's still yours to claim. It really does take about three floats for your body to fully learn to let go — the first is your body learning the room, the third is the one people are actually chasing. Three is how you get there.
Just $50 a float — your one-time first-timer price.
Already used it? No problem — just book your next float below.
The floats are the same as you remember. These are worth a look on your way back in.
One of the only couples tanks in the Boston area — roomier, longer, and built for two. Floating solo? Just request the XL when you book any float; there's a lot more room to stretch out.
See couples floats →Sauna and cold plunge cycles, plus targeted cold therapy for pain and recovery — both pair perfectly with a float. Float first, then recover, same day.
Learn more →If floating is becoming a habit again, membership starts at $65/mo — extra floats at $59, discounts on recovery services, and it's shareable. It pays for itself fast.
See membership options →This place is excellent. I consistently leave feeling relaxed and refreshed. The owner, Mark, keeps upgrading the float and recovery experiences they offer, and I am always impressed at the friendly, helpful service I receive there.
My fiancé and I had a wonderful experience. We both found the space warm and welcoming, the float itself very comfortable, and found ourselves incredibly relaxed afterwards. Highly recommend!
I'm glad my first float tank experience was at Float Boston. The owner Mark was willing to answer any questions to help ease my nerves and excitement. I immediately felt comfortable in his space.
A private suite with an infrared sauna — red light therapy built in — and a cold plunge. You cycle between them for a full hour: heat, cold, rest, repeat. Timers on the wall keep the rhythm, so you're not doing math in a hot room.
The whole suite is yours, and up to 2 people can use it at the same price. Most studios charge per person and put you in a shared space. We don't do either.
First session $50 with code love2sweat — enter it at checkout.
Everything below is included in every session — no add-ons, no upsells at the door.
Infrared penetrates into tissue rather than just heating the air, so you warm from the inside out. The 660nm red light layer runs the whole time you're in there — nothing extra to book, no extra time.
A serious plunge, right there in your suite. Start at 30–60 seconds and build from there. The first few seconds are the hardest part; what comes after is the reason people keep booking it.
Every session ends with time in the vitamin C filtered shower. It neutralizes chlorine and leaves skin and hair noticeably softer — a small thing that makes the finish feel finished.
The heat-cold cycle pumps blood through the system, flushing metabolic waste and moving fresh oxygen into tired tissue faster than rest alone.
Cold immersion is well studied for post-exercise soreness. If you're training again, or just carrying a stiff back around, this is the fastest-acting thing we offer.
Cold exposure is associated with a sharp dopamine response, and the heat brings its own endorphin lift. People tend to walk out talkative. No caffeine involved.
Heat forces stillness — no screens, nowhere to be — and the cool-down after a plunge mirrors the drop in body temperature that starts sleep. Best finished a couple of hours before bed.
Every session is a full 60-minute private suite. Packs never expire, and you can bring a guest every time at no extra charge.
$25 off a single 60-minute session. Regular price $75.
Book a sessionA flexible way to see what a regular practice feels like.
Buy 3-packBoth run on the same schedule, so we can book them back to back with a transition window between. Contrast first and you'll drop into the tank faster than you ever have; float first and the calm carries straight through the heat and cold. Just tell us you want both when you book.
Questions? Call or text 617-875-0725. New to it? Wear a swimsuit and bring water — we handle the rest.
Handheld cryotherapy with the Kaasen device — cold delivered to one area at a time instead of a whole-body chamber. Two very different reasons people book it:
Knees, shoulders, backs, old injuries, post-workout soreness. The cold pass drops tissue temperature fast to calm inflammation and quiet pain in the specific spot that's bothering you.
The aesthetic side: targeted treatments on specific areas, done as a series of sessions spaced days apart. Best paired with the rest of what you're already doing.
Full details, pricing, and what to expect are on the cryotherapy page.
