7 Questions to Ask Any Sauna Supplier Before It Goes on Your Gym Floor. Start With What the Heater Is Rated to Run.

You don't need to be a sauna expert to put one in a gym. You need straight answers from whoever is quoting it. Ask us the seven first. Then ask everyone else the same seven.

  • Family-run since 2021
  • 100% built in Europe, where sauna was born
  • Commercial-grade Harvia heaters
  • Import duty and customs handled by us

Editorial note. Written and published by PlusLife Health, which sells the saunas it describes, so read it as a supplier's notes rather than an independent review.

A sauna on a gym floor is a different purchase from one in a back garden, and almost none of the difference shows in a photograph. It sits in the heater, in where and how the cabin is built, and in what is on the quote before you pay a deposit. The bare list is here if you would rather just take it to your quotes.

  1. What is this heater rated to run: all day, or an evening?
  2. Where is the cabin built, and will it stand up to a British winter?
  3. What exactly is quoted before I pay a deposit?
  4. What will my electrician need, and who pays for that?
  5. When can it actually be on the floor?
  6. If it stops mid-timetable, who picks up, and how fast?
  7. Will you draw the room first?

If you only ask one, ask the first: what is this heater rated to run, all day or an evening? A home sauna runs one household's evening; a gym sauna runs a full timetable. If a supplier cannot give you an answer, that is also an answer.

Why these seven and not the seven on the brochure

Most sauna quotes an operator receives are written for a home: parts specified for one household's evening, asked to hold a hot room from the first session to the last.

The test underneath is simple: a supplier who has thought about commercial hours can tell you what the heater is rated to run without checking. One who has not will talk about the timber instead.

None of that shows in the photos. It shows in the answers.

Worth knowing

If you are not the one who signs: the seven are written to survive being forwarded, and question seven produces the one document that makes the case for you in a meeting you are not in.

01

What is this heater rated to run: all day, or an evening?

The heater is the one part that stops rather than wears. A cold room on a booked timetable is refunds and apologies that afternoon.

A weak answer sounds like

"It's a commercial sauna." "It's a 9 kW, that'll be plenty." Both swap hours for size.

A straight answer sounds like

Something specific about continuous running, tied to your hours, with the manufacturer's rating behind it. If they cannot tell you what happens at hour nine, you are being quoted a home unit at a business price.

And if a number does come back, ask whether it is the manufacturer's continuous-duty rating off the datasheet, or the supplier's own sentence. The document is the test. The number on its own is not.

Our answer

We specify commercial-grade Harvia heaters, the biggest sauna heater manufacturer in the world, publicly listed, built to run all day, sized to your room and timetable, with the manufacturer's datasheet available.

Ask us for the datasheet on the call, and ask everyone else for theirs. Anyone who has one sends it the same day.

On the controller

Every traditional sauna can be optioned with the Wi-Fi controller, a premium applies, or comes with built-in controls, depending on the heater you pick. Harvia is behind the app: it schedules heat-up, learns how long your room takes to reach temperature, and tells your smartphone when it is ready, so the room is hot for the first session rather than for whoever opens up. Prices are on the website, confirmed on the call.

  • Commercial-grade Harvia
  • Sized to your room and timetable
  • Manufacturer's datasheet available

02

Where is the cabin built, and will it stand up to a British winter?

Photos show the finish. They do not show how a cabin copes with a cold, wet January, which is exactly when your members want it most.

A weak answer sounds like

"Nordic-style." "Scandinavian-inspired." "Premium timber." Words about the look, and nothing about where it was built or what the walls are made of.

A straight answer sounds like

Where the cabin is built, documented, with a certificate of origin if you ask for one. The timber species and how it is treated for outdoor use. The wall thickness, and why that thickness. Documents and numbers, not adjectives.

Our answer

Our traditional saunas are handcrafted and 100% built in Europe, where sauna was born. Where they are produced and manufactured is documented, and a certificate of origin is available on request.

The timbers are premium thermo-treated species, Thermo-Aspen and Thermo-Pine, chosen for harsh climates, a wet British winter included. Benches are Aspen or Alder, knotless and smooth so nobody gets burnt on a hot seat, and bench heights are set for proper loyly, so the whole cabin is heated.

Walls on the premium traditional line are 42mm. Thicker walls mean better insulation, faster heat-up and a better sauna, which counts most on a cold morning. Heat-up runs 20 minutes to an hour on average, depending on the temperature you want and the weather. Every outdoor cabin is weatherproofed, so it can go indoors too.

  • Thermo-treated timber for harsh climates
  • 42mm walls for faster heat-up

03

What exactly is quoted before I pay a deposit?

The surprises are almost never in the cabin price: they are in delivery, assembly, customs and the line items nobody mentioned because nobody asked.

A weak answer sounds like

A cabin price, "plus delivery", "we'll sort the rest closer to the date". Or one all-in number with no breakdown: the same problem wearing a suit.

A straight answer sounds like

Cabin, heater specification, delivery, assembly, each with a figure, plus a named list of what is excluded. The exclusions are the more useful half.

If the cabin is built abroad, ask who the importer of record is. If it is you, the customs bill is yours as well.

Our answer

Your written quote itemises the cabin, the heater specification and delivery, each with a figure, before any deposit. The delivery charge on your order confirmation is the whole delivery charge: nothing is added later, as long as the address and site access are as you described them.

Every sauna is supplied delivered duty paid. We are the importer of record, so customs clearance, import duty and import VAT are ours, and nobody asks you for customs charges on delivery. Prices are in pounds: the website lists them including VAT, and your invoice shows the VAT separately.

The exclusions, in full

A page telling you to interrogate suppliers cannot be vague about its own. Delivery is kerbside as standard, with the crate unloaded within reach of the vehicle. Moving it on from there, siting, assembly and the electrical connection are not included unless we quote them separately, in writing, and the connection is always made by a registered electrician.

Whether commercial heater specification changes the cabin price is confirmed in your quote, in writing.

  • Itemised before any deposit
  • Import duty and customs on us
  • Exclusions named, not implied
04

What will my electrician need, and who pays for that?

Traditional saunas hard-wire, and the registered electrician who makes the connection is a separate, mandatory line in your budget.

A weak answer sounds like

"It just plugs in." "Your sparky will work it out." Neither is a specification, and unknowns get quoted generously.

A straight answer sounds like

The supply the specified heater requires, the phase, and a clear statement that this is a separate cost you pay someone else. Ask for it in a form you can forward to your electrician.

Our answer

Electrical connection is not in our quote unless we quote it separately, and we say so before you ask, because it depends on your premises rather than our unit. UK supply is 230 volts single phase, or 400 volts three phase, and a traditional sauna is hard wired either way.

The work must comply with BS 7671, the IET Wiring Regulations, and be carried out and certificated by an electrician registered with a competent person scheme such as NICEIC or NAPIT. The heater needs a dedicated circuit with RCD protection, some heater ratings need a three-phase supply, and an outdoor cabin needs a weatherproof, earthed connection.

The supply and phase for your specified unit comes in writing after the call, in a form you can forward to your electrician. Keep the installation certificate they give you: it is part of registering your warranty.

  • Hard-wired, registered electrician required
  • BS 7671, certificated
  • Supply and phase in writing after the call

Bring the room and the timetable. We come back with the space drawn.

The commercial consult is with a person rather than a form, and afterwards we build a 3D floor plan of your space with the units placed, so you see the suite your members would move through before you spend a pound on it.

Book the commercial consult

Bring your room dimensions.

05

When can it actually be on the floor?

A recovery suite is usually a dated plan, and "soon" is not a date, so ask early: the answer changes which unit you should buy.

A weak answer sounds like

"A few weeks." "It's on the next container." Neither is a date you can put in a timetable.

A straight answer sounds like

Whether the unit is made to order, a lead time in weeks, and a delivery window booked with you in advance. Enough to put a date in the timetable.

Our answer

Every sauna is made to order. Typical lead times are 6 to 10 weeks, depending on the specification, and yours is stated on your order confirmation. If your opening has a date, count back from it: the build comes before the delivery.

We deliver to mainland Great Britain, in a window agreed with you in advance, and the crate arrives kerbside, so plan the route from the kerb to the room.

  • Every sauna made to order
  • Typical lead time 6 to 10 weeks
  • Delivered to mainland Great Britain
06

If it stops mid-timetable, who picks up, and how fast?

A sauna that is down is a timetable of cancellations. What happens in the first working day after it stops matters more than anything in the brochure.

A weak answer sounds like

"We have great support." "Just give us a call." No hours, no target, and nothing about what happens after the call.

A straight answer sounds like

A named channel and the hours it is staffed, a response target for a unit your members cannot use, and the route to a fix: diagnosis, then an engineer or a part. In writing, in the terms you sign.

Our answer

Support is written into our commercial terms. Our UK support line and email are staffed Monday to Friday, 9am to 5pm UK time. When a sauna is out of use, our target is a first response within one business day of a complete report; when it is usable but impaired, two.

We diagnose remotely first, from your photos, video and error codes, then send an engineer or a replacement part. A complete report means the serial number, the fault and any error code, so putting all three in the first message is the quickest route to a fix.

  • UK support line, Monday to Friday
  • One business day target when a sauna is down
  • Remote diagnosis, then an engineer or a part
07

Will you draw the room first?

The last question separates a supplier from a box mover: will they lay out your actual space before anything is ordered?

A weak answer sounds like

"Send us the dimensions and we'll tell you what fits" is a stock check, not a layout. The wet path is what catches operators out: members come out of the showers or the cold plunge dripping, and if nobody drew where that water goes, it goes into the timber.

A straight answer sounds like

Yes, here is what we need and here is what you get back. Ask whether it costs anything and whether it shows your room or a generic one. Your own room, drawn, is the thing to put in front of whoever signs.

Our answer

Yes. Commercial spaces get drawn first. On the call we go through the room, the timetable, the power, where the drain is and how many units the space realistically takes. Afterwards our team builds a 3D floor plan of your wellness space with the units placed and sends it to you, free. No gate, no form beyond the booking.

Why we do it first

It is free because drawing the room is how we scope the job: work we do anyway, done before you commit rather than after.

What we do not promise: a turnaround time, or a plan built by anyone other than the people who took your call.

  • Free, after the call, no gate
  • Your room, your units, your wet path
  • The thing to hand to whoever signs

Will you still pick up in year three? Fair question.

PlusLife is family-run since 2021 and founder-operated, with husband and wife founders named on our About page. The team that takes your call specifies commercial-grade Harvia heaters, with Harvia parts behind every unit. Our commercial terms, warranty and support levels are published on this site and governed by the law of England and Wales, and every term comes in writing before any deposit.

We've done full wellness fit-outs with multiple sauna and cold rooms, and we drew the 3D floor plans that planned them.

The units these questions get asked about

Every price below is the cabin as listed on its product page today, in pounds including VAT, and subject to change. Heater specification and delivery are quoted on the call before any deposit, and question three sets out what else is on the quote and what is not.

Before you choose

Your spec sheet and the technical drawings for your model come with your written quote, so dimensions, seating and specifications are in writing before you decide.

When you do not need the commercial build

Not every commercial address runs a gym timetable, and paying for an all day specification you will never use is a poor purchase. A clinic seeing clients by appointment, a sauna for staff rather than members, or a floor still testing demand before it commits: loads like these look nothing like a full timetable, and a home-specified unit can be the right call.

And if the room, the power or the timetable does not justify an all day build, you hear that on the call rather than after the plan is drawn.

The seven, on one screen, ready to forward

Screenshot this or send it on. It works on our quote as well as anyone else's.

  1. What is this heater rated to run: all day, or an evening?
  2. Where is the cabin built, can you document it, and will it stand up to a British winter?
  3. What is on the quote before I pay a deposit, what is excluded, and who pays the import duty?
  4. What supply and phase will my electrician need, and can you send that to them?
  5. Is this unit made to order, what is the lead time, and how does it get from the kerb to the room?
  6. If it stops mid-timetable, who picks up, in what hours, and to what response target?
  7. Will you draw my actual room before anything is ordered, and what does that cost?

Not all seven weigh the same. Two decide the purchase: what the heater is rated to run, and what is quoted before the deposit; vagueness on either is the disqualifier. Two more tell you what kind of company you are dealing with: where the cabin is built, and who picks up when it stops. The other three are scheduling and scope.

One rider on question one, and it is the part that does the work: if a supplier gives you a number, ask them to email the manufacturer's datasheet it came from. A sentence instead of a document is your answer. That applies to us as well. Ask us for ours and the datasheet arrives the same day.

Ours in one line: commercial-grade Harvia heaters with the datasheet available; cabins 100% built in Europe; the quote itemised, exclusions named, import duty ours; a UK support line with a written response target; the room drawn after the call. If someone above you signs, the plan and the quote are what you send. Hold every supplier to the same seven, us included.

The questions operators ask next

Is there a commercial warranty?

Commercial warranty terms are published on our website. They carry usage requirements for commercial settings, how members use the units matters for cover, and both the term and the requirements are confirmed in writing on your quote.

Is anyone running one at commercial use that we could talk to?

Ask on the call about the full wellness fit-outs we have delivered. What we can put in front of you before you commit is the specification for your room in writing, our published commercial terms, and a 3D plan of your own floor.

What actually happens on the call?

You describe the room and the timetable, we ask about power, access and the drain, and you put as many of the seven to us as you want answered. You leave with the specification for your room, what a quote covers, and a date for the plan. There is no presentation to sit through.

What does a whole recovery suite cost?

The parts are published: cabin prices are on this page and every product page, in pounds including VAT. Heater specification and delivery are quoted on the call, import duty is ours, and siting, assembly and electrical are either quoted separately or priced by your own trades. Add them up for a real total instead of a headline one.

Our sign-off comes from a partner, a board or head office. What should we send up?

Two documents: the floor plan and the quote. The plan puts your actual room, units placed, wet path drawn, in front of someone who has never stood in it. The quote itemises the rest.

Ask us the seven. Then leave with the room drawn.

One free consult about your space, your timetable, your power and how members would move between hot and cold. Then a free 3D floor plan, with the units placed. No obligation, no follow-up pressure.

If the spend is next quarter, or next financial year, book it anyway. The drawing is the part that has to happen first, so that when the money moves, the room is already decided.
