A smart sauna uses an electric heater with app or remote control, letting you schedule heating or start it remotely so the sauna is warm when you arrive — especially useful in a cold climate where warm-up takes longer. The convenience is real: pre-heat on your way home rather than waiting. But remote and app start carry important safety requirements and should only be used if the heater and installation are specifically designed and approved for it, with the necessary safeguards, and installed by a licensed electrician. Smart control is a feature of electric heaters, not wood. If you value pre-heating convenience and set it up safely per the manufacturer and code, a smart sauna is a genuine cold-climate benefit.
Imagine starting your sauna from your phone on the drive home, so it’s warm the moment you arrive — no waiting in the cold for it to heat. That’s the promise of a smart sauna: an electric heater with app or remote control for scheduling and pre-heating. In a cold climate, where warm-up takes longer, the convenience is genuine — but so are the safety requirements. This guide covers what smart saunas offer and how to use one safely.
What a smart sauna is
A smart sauna uses an electric heater with app or remote control, letting you:
- Schedule heating in advance.
- Start it remotely so the sauna is warm when you arrive.
- Monitor or adjust settings.
It’s a feature of electric heaters — not wood — via WiFi or app connectivity to compatible controls.
The cold-climate appeal
Its main benefit shines in winter. Because an outdoor sauna takes longer to warm up in the cold, being able to pre-heat on your way home means the sauna is ready when you arrive — rather than waiting in the cold. Smart control turns the longer winter warm-up from a wait into something that happens before you get there — a real convenience for frequent winter use.
Safety comes first
Used correctly on approved equipment, it’s a designed-in feature; used improperly, it’s a hazard.
Not for wood heaters
Smart control is an electric-heater feature. A wood heater must be physically lit and tended, so it can’t be started remotely from an app. A wood sauna’s appeal is the traditional fire and independence from electricity — not remote convenience. The two offer different things — see electric vs wood.
Is it worth it?
| Worth it if… | Skip it if… |
|---|---|
| You value pre-heating convenience | You prefer simplicity or a wood fire |
| You sauna often in a cold climate | You don't mind waiting for warm-up |
| You'll set it up safely | You want to avoid the extra cost/setup |
The convenience is real and welcome for frequent cold-climate use — provided you accept the compatible heater, professional install and remote-start safety.
Common mistakes
- Using remote start on a heater not designed for it.
- Improvising app control without the required safeguards.
- Skipping the licensed electrician and code compliance.
- Expecting smart control from a wood heater.
- Leaving the heater area cluttered when pre-heating unattended.
Next steps
If pre-heating convenience appeals, choose a compatible smart electric heater, have it installed by a licensed electrician, and use remote start only per the manufacturer and remote-start safety. Set up safely, a smart sauna is a genuine cold-climate benefit — arriving to warmth instead of a wait. Prefer the fire and simplicity? A wood sauna is the other path.
Frequently asked questions
What is a smart sauna?
A smart sauna uses an electric heater with app or remote control, letting you schedule heating or start it remotely so the sauna is warm when you arrive. It typically means WiFi or app connectivity to a compatible electric heater and controls. The main benefit is pre-heating convenience, valuable in a cold climate where warm-up takes longer. It's a feature of electric heaters, not wood, and it must be set up safely per the manufacturer and code, since remote start carries safety requirements. Done right, it lets you skip the wait for the sauna to heat.
Can you control a sauna from your phone?
With a compatible smart electric heater and its app, yes — you can schedule or remotely start heating so the sauna is ready when you arrive, and monitor or adjust settings. This requires a heater and controls specifically designed for app or remote operation, installed by a licensed electrician, and used per the manufacturer's safety requirements, since remote start has important safeguards. Not every heater supports it. So phone control is possible with the right smart-capable heater, set up safely. See our guide on sauna remote-start safety.
Is remote-starting a sauna safe?
Only if the heater and installation are specifically designed and approved for remote or app start, with the necessary safeguards, and installed by a licensed electrician to code. Remote start means heating an unattended sauna, so it carries real safety requirements — the heater area must be clear, and the system must have the required safety features. It should never be improvised or used on a heater not designed for it. Follow the manufacturer's instructions and any code requirements. Used correctly on approved equipment, it's a designed-in feature; used improperly, it's a hazard. See our remote-start safety guide.
Do smart saunas save time in winter?
Yes — that's their main appeal in a cold climate. Because an outdoor sauna takes longer to warm up in the cold, being able to schedule heating or start it remotely on your way home means the sauna is ready when you arrive, rather than waiting in the cold for it to heat. So a smart sauna turns the longer winter warm-up from a wait into something that happens before you get there. It's a genuine convenience for frequent winter use, provided it's set up and used safely. See our winter comfort tips.
Can a wood-burning sauna be a smart sauna?
Not in the same way — smart, app and remote control are features of electric heaters, which can be switched on electronically, whereas a wood heater must be physically lit and tended, so it can't be started remotely from an app. A wood sauna's appeal is the traditional fire and independence from electricity, not remote convenience. So if you want smart pre-heating, an electric heater is the route; if you want the wood fire, you tend it in person. The two offer different things. See our electric vs wood comparison.
Is a smart sauna worth it?
It's worth it if you value the convenience of pre-heating — arriving to a warm sauna rather than waiting — particularly for frequent use in a cold climate where warm-up is slow. The trade-offs are that it requires a compatible smart electric heater, professional installation, and careful adherence to remote-start safety. If those suit you, the convenience is real and welcome. If you prefer simplicity, a wood fire, or don't mind waiting for warm-up, it's an optional extra rather than essential. Weigh the convenience against the setup and cost.
