If you search “best sauna NYC” long enough, one place keeps coming up in the serious reviews — not the listicles that count steam rooms and infrared boxes as saunas, but the reviews from people who clearly know what they’re looking for.
That place is Bathhouse in Red Hook, Brooklyn.
I haven’t been. I’m not in New York yet. But I’ve read enough about it to say it’s the right benchmark — and to explain exactly what you should be looking for when you walk in.
What the reviews actually say
The detail that comes up most consistently: you can throw water on the stones. That sounds like a small thing. It isn’t. In a city where most “sauna” stoves have a “do not add water” sign bolted to them, this is the whole game.
Reviewers on Google and Yelp describe the kiuas as genuinely hot — temperatures in the 80–90°C range, which is where sauna actually starts. Multiple reviews mention the löyly by name, which tells you the people going are not first-timers looking for a warm room. The cold plunge gets consistently good marks. The space itself — an old industrial building in Red Hook — sets the right tone before you’ve even undressed.
The criticisms are minor and consistent too: book well in advance (weekend slots fill by Wednesday), the pricing is around $65 per session, the ambient music is reportedly more wellness-spa than sauna-cabin. None of these are deal-breakers.
What matters: a real kiuas, real steam, real cold contrast. In NYC, that’s rare enough that it’s worth the trip to Red Hook.

What to actually look for when you visit any sauna in New York
Since most people reading this are evaluating places for the first time, here’s the short version of what separates a real sauna from a hot room with Nordic branding:
The stove. Is there a kiuas with actual stones on top? Are the stones stacked properly — not a thin layer, but a real pile that holds heat? Ask before you book whether you can add water.
The temperature. Anything below 70°C is not a sauna in any meaningful sense. 80–90°C is the target. Some places post their temperature; others you have to ask.
The steam. If you can’t throw water on the stones, you can’t get löyly — the burst of steam that is, quite literally, the whole point. A dry sauna is a hot room. Fine, maybe, but not what we’re talking about here.
The cold contrast. A proper session needs heat and cold alternating. A cold shower works. A plunge pool at 10–12°C is better. “Cold” that’s actually 18°C is not cold. But nothing beats an actual ice hole.
Go to Red Hook. Check these things when you arrive. You’ll know within the first round whether it’s the real thing.
