Collection: 3 Person Indoor Infrared Saunas

3 Person Indoor Infrared Saunas — Family Cabins from £3,695

A 3 person infrared sauna gives you genuine family capacity — or the luxury of stretching out solo. At around 1.5m × 1.5m, these cabins offer full bench width for three seated adults, or enough length for one person to recline, while still fitting comfortably in a home gym, garage conversion, or garden room. Like all infrared cabins they run at a gentle 45–65°C and cost pennies per session.

Our 3 Person Range

The 1500mm × 1500mm KY007 (£3,695) delivers full-surround far infrared heating, chromotherapy lighting, and Bluetooth audio at the most accessible price in this size. The flagship GH Vision T3 Low-EMF Full Spectrum (£5,995) adds near-infrared LEDs for skin renewal, mid-infrared for muscle recovery, an oxygen ioniser, and app-controlled pre-heating — our premium 3 person choice.

Space and Wiring

Allow around 1.5m × 1.5m of floor space, 1.9–2m of ceiling height, and a small air gap around the cabin. 3 person cabins typically need a 20-amp dedicated circuit rather than a standard plug — a straightforward job for a qualified electrician, and we confirm the exact requirement before you order. Flat-pack assembly takes around 2 hours with two people; no plumbing or flue needed.

Running Costs

Expect a draw of 2–2.5 kW — roughly £0.50–£0.60 per 45-minute session at average UK rates. Even used daily by a family, that's a few pounds a week. Model your exact figure with the Sauna Running Cost Calculator.

Other Sizes

Couples can save space with a 2 person infrared sauna; larger households should compare 4 person cabins. Browse the full indoor infrared saunas range or the complete infrared sauna collection.

3 Person Infrared Sauna FAQs

How much does a 3 person infrared sauna cost in the UK?

From £3,695 for the 1500mm far infrared KY007 up to £5,995 for the low-EMF full-spectrum GH Vision T3 with delivery and installation included.

What size is a 3 person infrared sauna?

Around 1.5m × 1.5m of floor space with a cabin height of roughly 1.9–2m — wide enough for three seated adults or one person reclining.

Do 3 person infrared saunas need special wiring?

Usually yes — most need a 20-amp dedicated circuit rather than a standard 13-amp plug. It's a routine job for a qualified electrician and we confirm the requirement per model before purchase.

Can one person use a 3 person sauna?

Absolutely — many buyers choose this size for solo use because the bench is long enough to lie down, which isn't possible in 1–2 person cabins.

Is full spectrum worth it in a 3 person sauna?

If you're buying for training recovery or skin benefits, yes — the GH Vision T3 adds near and mid infrared on top of far infrared. For relaxation-first use, the far infrared KY007 delivers the core experience for £2,300 less.
