SenseStack is operational readiness infrastructure for commercial saunas. It validates heat-up time, confirms operating temperature, and tells operators when their sauna is ready for guests.

How does SenseStack know when a sauna is ready?

SenseStack uses a high-temperature probe mounted externally to the sauna to record heat-up curves and measure when the sauna reaches its optimal operating temperature range.

Who is SenseStack for?

SenseStack is built for commercial sauna operators — gyms, wellness centres, hotels, and spas who need to ensure their saunas are consistently ready and at operating temperature before guests arrive.

How much does SenseStack cost?

Pilot access is €120 per monitored sauna for a 30-day operational readiness validation phase. This is credited toward ongoing subscription if you continue after the pilot.

Where is SenseStack available?

SenseStack is currently piloting with commercial sauna operators in Ireland. Apply for founding access to join the pilot programme.

Sauna Operators

Monitor temperature, door activity, readiness and operating conditions across every sauna. Know exactly when each cabin is ready, and how long it took to get there.

The Problem

What's missing today.

Operators rely on guesswork — manual checks, guest complaints when a sauna isn't hot enough, no record of how long it took to reach target.

How SenseStack Solves It

Continuous visibility, no guesswork.

SenseStack Sauna installs externally with internal sensors. Live readiness state, heat-up curves and target-range compliance — across one cabin or a fleet.

Free tool

Size the heater, estimate the heat-up.

Work out your cabin's effective volume, the heater kW it needs, how long it takes to reach 80 °C and what a day of heat costs. Free, no sign-up.
