Sauna Water Bottle – White

Your sauna is doing serious work. Your water bottle should too. Most bottles aren't built for heat. Plastic leaches. Metal alters taste. The Dialed Labs Glass Sauna Bottle is different — borosilicate glass handles extreme temperatures without releasing a single chemical into your water. A natural cork sleeve acts as a thermal barrier, keeping the heat off your hand so you can grab it straight from a hot sauna bench. The easy-carry lid means one grab and you're in. Pure water, pure recovery. Nothing else. Specifications Capacity: 20 fl oz / 590ml Dimensions: 9.5" (H) x 2 5/8" (D) Material: Borosilicate glass Sleeve: Natural cork Lid: Wood Dishwasher safe: Yes (without sleeve)

Hydration isn't just about volume. It's about what's in your water. Glass construction — drink clean Conventional plastic bottles release BPA, phthalates, and microplastics when exposed to heat — exactly the conditions you're drinking in. Borosilicate glass is chemically inert, meaning nothing migrates into your water regardless of temperature. What you put in is what you drink. Cork sleeve — heat handled Natural cork is one of the most effective thermal insulators in the world. Its cellular structure traps air, blocking heat transfer so the exterior stays cool to the touch even when the glass inside is hot — no bulk, no plastic coatings. Easy-carry lid — hydration on your terms In the sauna, convenience is compliance. If your bottle is hard to grab, you drink less. The secure, leak-proof lid with carry loop means one effortless reach between sets — keeping you consistently hydrated through every round of heat. Why it matters in the sauna Core body temperature rises fast in the heat. Sweat rates can exceed a liter per hour. Consistent hydration during sessions supports cardiovascular performance, prevents heat stress, and accelerates post-session recovery. The right bottle removes every barrier to drinking enough.
