NEW: First UK barrel sauna available with gas heat — Steam & Oak × FinSteam

Pick "+ FinSteam Aurora 81 R14S Gas Heater" at checkout and your barrel ships with engineered ventilation built for gas + a bundled FinSteam Aurora 81 R14S gas heater package — ready to light on a UK propane bottle the day it lands. Steam & Oak is the only UK retailer offering this. No electrician, no chimney, no fire to tend. Hot in 15 minutes, turn a dial. The Aurora 81 is the only CE-marked electricity-free sauna gas heater on the European market (FinSteam's stated claim) and the heater that powers the FinSteam NOIR Signature packages.

Why gas changes the equation

Humidity	Naturally humid (combustion vapour)	Dry until löyly	Dry until löyly
Running cost / session	~£1.50-2.00	£2-4 logs	£1.75-3.25
Safety	EU-cert, auto O₂ shut-off	Open flame	Electrical

The real cost to your first sauna — gas vs electric

An electric sauna's shelf price isn't the price to your first löyly. A 6.8–9 kW electric heater needs its own dedicated circuit, wired by a qualified electrician and signed off under Part P — typically £800–£1,500, plus the wait to get one booked. The FinSteam gas heater connects to a UK propane bottle outside, like a patio heater: no dedicated circuit, no electrician for portable use, and it's hot on the day it arrives.

	Electric (from)	Gas (FinSteam)
Cabin + heater	£4,795	£6,790
Electrician — dedicated circuit + Part P	£800–£1,500	£0
Ready to use	After wiring is booked + signed off	Day of delivery
Real total	£5,595–£6,295	£6,790

The ~£2,000 gap on the shelf narrows to roughly £500–£1,200 once the electrician is in the sum — and the gas sauna doesn't wait on a sparky's diary. (Portable use needs no Gas Safe engineer; a fixed install does. A standard UK 13 kg Calor propane bottle runs the heater for a dozen-plus sessions.)

What "gas-ready" means — engineered vents built into the cabin

The gas variant ships with wooden louvre vents at the FinSteam-specified sizes built into the cabin: intake ≥350 cm² low next to the heater (drawing fresh air directly from outside), exhaust ≥250 cm² high in the opposite corner (discharged directly to outside). FinSteam explicitly exclude plastic disc / twist valves — the gas variant doesn't ship with those. The vent configuration and the FinSteam heater are certified together under EU Gas Appliance Regulation 2016/426. Pick the electric or wood-fired variant instead and the sauna ships with the appropriate vent set for that heat type — pick the heater at checkout and the build matches.

What's in the gas variant package

The barrel shell + porch + alder bench + 8mm tempered glass — same build as the electric/wood variants of this model.
Engineered gas-ready ventilation built in (wooden louvres, FinSteam-spec sizes).
FinSteam Aurora 81 R14S gas heater — 8.1 kW, EU Type-Examination Certificate, AENOR-tested under Reg 2016/426. ODS oxygen-depletion auto-shutoff + flame monitoring. Configuration includes Orbis 14 stone cage + Halo safety rail + Njord heat shield as standard.
UK propane regulator + 1.2 m CE-marked gas hose (I3P 37 mbar, 27 mm clip-on for standard Calor 13 kg propane bottles).
40 kg pre-washed FinSteam sauna stones, sized for the cage.

The Aurora 81 R14S retails standalone for £2,395 — the gas variant bundles it with the engineered cabin build at a single price (£6,790 inc VAT). Zero warranty returns on the FinSteam heater in the last 12 months. More on the Aurora 81.

What you'll need to source locally

A standard UK 13 kg Calor propane bottle — bought locally. The included regulator + hose connects to one.
A Gas Safe registered engineer for the gas connection on a fixed install. Required by UK regulation for fixed gas connections.

Steam & Oak Barrel Sauna 2.4m with Porch — pick your heater at checkout

Steam & Oak — one of the very few UK sauna brands that lets you choose gas, wood-fired OR electric on the same listing. Pick at checkout.

The choice (heater options)

★ + FinSteam Aurora 81 R14S Gas Heater (UK first) — the new gas option. See full details above.
Shell only — buy the cabin, source your own heater.
+ Electric Harvia PC70 6.8kW — sized for the interior, single-phase ~25A circuit.
+ Electric Harvia PC90 9kW — for faster heat-up.
+ Wood-Fired Etna 12 stove + flue kit — traditional log-fired ritual, no electrical install. Includes chimney pipe + flashing kit. (Wood-fired stove is rated for 6-12m³ saunas.)

The 2.4m barrel extends the entry barrel with a 0.4m covered porch — the small detail that turns a sauna kit into a proper garden building. The porch is where people sit to cool down between löyly throws, change footwear, hang towels. 44mm Scandinavian spruce walls + alder benches + 8mm tempered glass throughout.

Running cost + warm-up (the question buyers ask first)

Configured with the FinSteam Aurora 81 R14S gas heater, running cost is approximately £2.00-£2.50 per 60-90 minute session (around 0.6 kg propane per session at a typical £47 / 13 kg Calor refill). Warm-up: 15-20 minutes from cold to 70-75°C.

Configured with a Harvia 6.8kW electric heater, this sauna runs at £1.75–£2.25 per 90-minute session at the 2026 price cap. Warm-up takes around 30 minutes. Configured with a 9kW Harvia, those numbers move to about £2.00–£2.50 per session. With the Etna 12 wood-burning stove, the running cost moves off the electricity bill entirely — typical hardwood log cost is £2–£4 per session. See our full running-cost breakdown.

The porch advantage

Comparable 4-person UK barrels — our own Rustic Barrel 6ft is the closest at this capacity — don't have an integrated porch. The 0.4m covered space at the door is genuinely useful: somewhere to sit during cool-down without standing on wet grass, to remove boots before stepping inside, or to position a small wood log store next to the wood-fired heater. Practical detail, real quality-of-life difference.

Warranty & Aftercare

Warranties on hot tubs, saunas, cold plunge tubs, and heat pumps look complicated because each product category has different fault patterns and different cover periods, but the underlying logic is consistent: the warranty protects you against manufacturing defects and premature equipment failure, not against wear-and-tear, misuse, or installation errors. This FAQ explains what's covered across our product range, what isn't, how to register a warranty, and what we need from you to handle a claim quickly. We're a UK retailer working with accredited UK distributors; warranty support flows through us as the customer-facing channel with the distributor's engineer network handling on-site work.

Sauna warranties vary by manufacturer and model, but the typical coverage on saunas we sell breaks down as: structure and cabin (5 years) — wood panelling, glass panels, structural fixings; heater (2 years) — element, controls, thermostats; electrical components (2 years) — control panels, lighting, audio, Bluetooth modules. Outdoor saunas typically carry the same structural cover as indoor, plus a separate sealant/weatherproofing guarantee that runs 2 years. Our Slate, Cairn and Holl’s ranges follow this pattern; specific cover periods are confirmed in the warranty card shipped with each unit. The warranty covers manufacturing defects (faulty welds, electrical faults out of the box, panels failing within cover period) and premature failure (a heater failing in year one rather than year ten). Faulty components are repaired or replaced at the distributor's discretion; we coordinate the on-site engineer visit.

Warranty cover excludes anything outside of manufacturing defects or premature failure. Specifically excluded:

Wear-and-tear — filter replacements, sauna stones requiring rotation/replacement, gasket softening over years of use, normal acrylic ageing.
Water-chemistry damage — corrosion, scaling, or shell damage caused by neglected water chemistry (pH out of range, sanitiser at incorrect levels, calcium hardness untreated). This is the #1 reason claims are declined.
Installation errors — damage from poor electrical install (wrong cable rating, missing RCD, exposed connections), unsuitable base (uneven, undersized, settling), or non-compliant pipework. See the dedicated question below.
Misuse — using a hot tub or sauna outside its rated parameters (e.g. exceeding rated occupant load, running an outdoor unit indoors or vice versa without manufacturer approval).
Cosmetic damage caused after delivery — scratches, chips, knocks. Cosmetic damage at delivery is covered if reported within 48 hours.
Acts of nature — flooding, lightning strikes, freezing damage from un-winterised tubs. Insurance handles these.
Modifications — third-party heater retrofits, unofficial accessories, or any change that takes the unit outside its certified configuration.
Consumables — sauna stones, filter cartridges, water-care chemicals, replacement bulbs.

Your statutory rights under the UK Consumer Rights Act 2015 are unaffected: if the product is faulty, not as described, or not fit for purpose, you have remedy regardless of what the manufacturer warranty says.

For Steam & Oak hot tubs and most accessory items, warranty registration happens automatically at order — your order record on Shopify serves as proof of purchase and warranty start date. No further action needed. For manufacturer-branded units (Holl’s saunas, Harvia and HUUM heaters, Passion ice baths, heat pumps), some manufacturers require a separate registration step on their own portal — the warranty card shipped with the unit will tell you. We recommend: register within 30 days of delivery, keep your order confirmation email safely archived, take photos of the unit serial number plate at install (usually on the equipment compartment for hot tubs, the heater for saunas, the chiller unit for cold plunges, or the side panel for heat pumps), and keep a basic ownership log (commissioning date, water-change dates, filter changes for hot tubs). The serial number is the single piece of information a warranty engineer will ask for first.

Yes. Every product we sell carries the relevant manufacturer's warranty (Steam & Oak own-brand, Holl’s, Harvia, HUUM, Passion, PortaSauna, FinSteam, etc.) and is backed by UK consumer-protection law. The warranty card shipped with each unit specifies the exact cover periods; for a quick summary by product type: hot tubs — 2 years equipment pack (some performance models 3 years), 5 years cabinet, shell varies by model; saunas — 5 years structure, 2 years heater and electrical; cold plunge tubs — 2 years on the chiller and electrical, 5 years on shell/structure; heat pumps — 2–5 years depending on brand and tier. Browse our hot tubs, saunas, and cold plunge tubs collection pages for per-product cover.

You contact us; we coordinate with the distributor's engineer network. Don't go direct to the manufacturer or distributor — the cover terms route through us as the retail channel, and going direct can complicate the claim or push you outside the documented process. The fastest channel: email help@steamandoak.co.uk with your order number, the unit serial number, a clear description of the fault, and (ideally) a short video showing the symptom. Founder Sarb Gill (BSc Biology) personally reads warranty enquiries and replies the same working day. For urgent cases (no heat in winter, water leak, electrical fault), call 03330 1515 33 Monday–Friday 9:00–17:00.

What do you need from me to process a warranty claim?

To process a claim quickly, please include:

Order number (from your Shopify confirmation email).
Unit serial number (from the serial plate on the unit).
Date of installation/commissioning (warranty start date for hot tubs runs from delivery).
Clear description of the fault — what it does, when it started, what changes if anything (running on jets only, running on heat only, etc.).
Photos or short video — engineer time is precious; a 30-second video showing the symptom often skips a needless first-visit diagnostic.
For hot tubs: water-chemistry log — if the fault could be water-chemistry-related (corrosion, scaling, shell discoloration), recent pH/alkalinity/sanitiser test results help us argue the case with the distributor.

The distributor's engineer typically books within 5–10 working days for non-urgent cases, sooner for safety-critical ones.

Does poor installation affect warranty?

Yes — installation errors are one of the main reasons claims are declined. Specifically: a hot tub installed on an unsuitable base (uneven decking, undersized concrete pad, soft ground) and developing shell stress cracks will not be covered as a manufacturing defect. A sauna heater wired without the correct RCD, cable rating, or supply circuit and failing prematurely will not be covered. A cold plunge tub installed without considering freeze-protection requirements and damaged by ice formation will not be covered. Always use a qualified electrician for hardwired installs (Part P-registered, working to BS 7671 18th Edition), and confirm the base meets the manufacturer's published spec before delivery. Our Hot Tub Base & Placement Guide and Site Prep Checklist cover the install requirements for each product category.
