Nightjar Sauna Grand Opening
Nightjar Sauna is officially open, and you’re invited.
Every Nightjar sauna is hand-built right here in Grand Rapids. On December 10 we’re opening the doors to the shop where it all happens, and debuting the newest part of Nightjar: our cold plunge.
The cold plunge launch. This is the first chance anyone gets to try it. Pair it with a round in the sauna for the classic hot–cold contrast and see what the hype is about. Do 30 seconds or go for the full 2 minutes. Either way, you’ll be one of the first in. Last 2 minutes and win a Nightjar sauna towel (while supplies last).
Try the saunas. Warm up before or after your plunge.
Bites + beverages. Stay and hang out between rounds.
✂️ Ribbon cutting at 4:45 PM.
Raffle. Every guest gets a raffle ticket at check-in, and we’ll draw for prizes during the event.
This is an adults-only event (18+). Please leave the little ones at home for this one.
Please RSVP so we can plan food and get you checked in quickly. Bringing your spouse or a friend? Add them as a guest when you RSVP. Anyone planning to use the sauna or cold plunge will need to sign their own waiver.
Ready to experience the sauna and cold plunge? We’d love for you to join us for a round of heat and a plunge into the cold. Bring a swimsuit and a towel, and sign the waiver ahead of time: Sign the waiver here. Changing space is available.
Not up for a plunge this time? Come for the bites, the company and the celebration. We’d love to see you either way.
