The Harvia Onni Mini Buying Guide
How It Works
The Onni Mini is the simplest sauna to bring home — full-spectrum infrared, premium materials and true plug-and-play convenience. Below is the step-by-step journey from order to your first session.
1. Place Your Order Choose the Onni Mini and complete your purchase online; you'll receive an order confirmation with your reference number.
2. Dispatch & Preparation Your order is prepared for dispatch. The cabin is supplied flat-packed in modular sections with all hardware and the instruction manual included.
3. Delivery to Your Address Free kerbside delivery across the UK mainland. Please ensure someone is available to receive the boxes; you'll typically be contacted to arrange a convenient day.
4. Receipt & Inspection Inspect all packaging on arrival and check every component against the manual. Report anything missing or damaged straight away, and keep packaging until the cabin is fully assembled and working.
5. Assembly & Plug-In The Onni Mini is designed for straightforward self-assembly — if you're comfortable with flat-pack furniture, you'll be fine (two people and basic tools recommended). Position it indoors on a level, dry floor with adequate ventilation, then plug it into a standard 13-amp wall socket — no electrician or hard-wiring required. We recommend a dedicated wall socket rather than an extension lead. Professional installation is available if preferred.
6. First Session & Aftercare Set your temperature, lighting and audio, and enjoy your first full-spectrum infrared session. Care for the wood, keep the cabin ventilated, and periodically test the controls, lighting and audio. Keep your proof of purchase for any warranty claim.
