FAQ
Common questions
How much is a sauna session in Boston?
An infrared sauna session at IV League Hydration is $45 for 30 minutes. You can also add a 30-minute sauna session to any IV drip visit for the same $45.
Where is your sauna in Boston?
We have infrared saunas at both South Boston clinics: A Street (West Campus) and L Street (East Campus) at 47 L Street. The cold plunge for sauna and cold contrast rounds is at L Street only.
When is the sauna open?
Monday, Tuesday, Thursday and Friday 10am–6pm, and Saturday–Sunday 10am–2pm. We're closed Wednesdays. Book online to see open times for the day.
Is it a traditional or infrared sauna?
Infrared. It heats your body directly and runs around 120–140°F instead of the 180–200°F of a traditional sauna, so most people find a 30-minute session comfortable.
Can I do a sauna and cold plunge in Boston?
Yes. At L Street you can alternate the infrared sauna with our 45–55°F cold plunge (Fire & Ice). A cold plunge session is $45.
Can I pair the sauna with an IV drip?
Yes. Sweating uses up fluid and electrolytes, so many guests add a sauna session to a hydration drip in the same visit.
What should I bring?
Swimwear or light athletic clothes and a change of clothes. Towels and water are provided. Arrive hydrated.
What Boston is saying
A selection of five-star reviews from real clients across our A Street, L Street, and mobile IV service.
"Absolute lifesaver after a long weekend. The nurses are so friendly and knowledgeable — I walked out feeling brand new. The A Street clinic is beautiful too. I'll be back!"
"Best IV drip in Boston, hands down. Courtney and the team really care and take the time to build the perfect drip for you. The Hail Mary is a game-changer before a long travel day."
"I've been going for the The Knockout drip and B12 shots for months. My energy and skin have never looked better. It's clear these are real nurses who know what they're doing."
"Booked the mobile IV for a bachelor party at our Airbnb — nurse showed up early, super professional, and everyone felt human again in 45 minutes. 10/10 would recommend."
"The semaglutide program has been life-changing. Real medical oversight, monthly check-ins, and no gimmicks. So glad I chose IV League over the sketchy online options."
"Went in for a NAD+ drip and left feeling sharper than I have in years. The team explains everything, the space is clean and calm, and prices are super transparent."
