Domes for a Spa or Wellness Business

Why domes suit wellness commercially

• An experience guests pay for. A relaxation or treatment dome under open sky is a differentiator: the kind of space that helps justify premium pricing and gets shared online.
• Moisture-resistant and durable. Plunges and wet treatments create punishing conditions. Solid polycarbonate resists moisture and holds its shape where fabric tents sag and fail, though humid use still means condensation, so ventilation matters (see below).
• Year-round, weatherproof. Cold therapy is at its most bracing in winter, and a sauna is most welcome when it's freezing. Domes keep both practical all year, with guests sheltered from the weather between rounds.
• Flexible offering. Cold plunge, yoga, meditation, post-treatment relaxation or a cool-down space beside a purpose-built sauna: domes flex across your menu, and several together create a wellness garden.

Why Extreme for a spa setting

Public, humid, high-turnover use is the toughest test:

• Our strongest specification. Extreme has 3 mm panels, twice as thick as Original and stainless steel bolts, nuts and anchors, a sensible choice around plunges and wet treatments, and it's the specification we recommend for commercial use and exposed sites. For a bigger studio, the 5 m Large comes in one maximum-thickness specification.
• Included openings keep costs predictable at scale. The solid sliding door, windows and roof vents come with every dome rather than as extras, which keeps a multi-dome spa's sums simple; when comparing suppliers, check what each includes and their current terms. A wellness garden of three or more domes saves on every one: £100 off each at three, rising in steps to £300 off each from ten.
• Reliable supply. UK stock, free next-day delivery to eligible UK destinations for orders placed by 2pm, Monday to Friday and Extreme's 5-year warranty support a planned build-out, and our Built for you installers can build and anchor the domes for you.

Ventilation, hygiene and safety

Wellness use puts ventilation and safety front and centre:

• Ventilation and saunas: the included roof vents, windows and door are essential in a humid space. A dome is a garden room, not a sauna cabin, so keep sauna or steam heat inside a purpose-built unit installed to its maker's instructions and clearances, rather than heating the dome itself (more in our guide to a sauna or cold plunge in a garden dome).
• Heating: electric heaters are the simplest option. Any fuel-burning heater needs ventilation and a carbon monoxide alarm, and a wood burner needs a HETAS-registered installer, a proper flue and the clearances the installer specifies. Keep every heat source well away from the panels; see how to heat a garden dome.
• Hygiene: plan wipe-clean, non-slip flooring and proper drainage for plunges and wet treatments, and check the base can carry a filled plunge tub's weight (ask the tub maker; a concrete pad may be needed). Commercial wellness has cleaning and water-management standards to meet.
• Electrics and water: mains electrics by a registered electrician (Part P in England and Wales) with outdoor-rated fittings and RCD protection; plumbing by qualified trades.
• Fire documentation: if your venue needs a specific fire classification (UK/EU: EN 13501-1), contact us and we'll confirm the documentation. Airflow and clearances around heat sources remain your responsibility.

Compliance for a wellness business

Treating paying clients brings obligations to handle properly:

• Fire safety: a fire risk assessment covering heating, saunas, furnishings and escape routes.
• Planning and licensing: commercial use usually needs planning permission (change of use, siting), and some treatments carry licensing or registration requirements; check locally.
• Insurance and health standards: commercial and treatment liability cover, plus relevant health, hygiene and water-safety standards.
