Frequently Asked Questions
How long does the sand take to run through?
Exactly 15 minutes — a full drain matches a typical sauna session, so you can flip it and know when your time is up.
What is the Rento Sand Timer made of?
A bamboo and aluminum frame around the glass hourglass, built to handle sauna heat and humidity without warping.
How do I mount it in my sauna?
It’s designed to hang on the sauna wall. Keep it a comfortable distance from the heater so the glass and sand inside last.
Does it need batteries or maintenance?
No — it’s a simple gravity timer with no batteries, wiring, or moving parts. Just flip it over to start again.
What if I want more than 15 minutes?
Flip it again for another 15-minute round, or use it as a visual pace-setter rather than a strict cutoff.
