When the Catalogue Doesn't Fit the Room: Custom Gym Saunas, Built From Scratch and Sized to Your Floor

PlusLife Max Traditional Sauna 2.0: rounded-square timber outdoor cabin with a full tinted-glass front, a centred glass door and a black shingle roof, standing on grass in front of pine trees
Max Traditional Sauna 2.0. Traditional line, designed in Australia, 100% built in Europe. Cabin from $14,990. This page is about the rooms it does not fit.

Built to the room, not the brochure. The whole page in six lines.

A sauna for a gym is not a home cabin scaled up, so the first question is whether your room takes a catalogue cabin.

  • Does the catalogue fit your room? Plenty do. If yours does, we say so and stop there. The four questions that settle it.
  • Sized to a gym, not a family. A group off the timetable, the door opening all day. Different footprint, different heat load.
  • When the catalogue does not fit, we do not scale up a home cabin. Our in-house build team builds the sauna from scratch to the space. How that works.
  • What size heater does the room need? Sized to the room, not read off a home spec sheet. How the sizing works.
  • Odd room? That is what the call is for. Power, drainage, footprint, delivery and assembly are scoped on the call. What the call covers.
  • Catalogue cabins carry list prices; a build is quoted to the room. What is in a quote and what is not.

The offer, plainly

Free. One call about your room, your timetable and your power: whether a catalogue cabin fits or the room needs a build, what the heater has to do, and a delivered-and-assembled quote.

Then a free 3D floor plan of your wellness space, with the units placed. No obligation, no deposit taken on it. If the answer after the call is "not this year", that is a fine one.

A sauna for a gym is not a home cabin scaled up

Every sauna in every catalogue, ours included, was drawn around a household: two people, sometimes four, once an evening, then it cools overnight. The dimensions and the heater come from that.

Put that cabin on a gym floor and you have changed the job without changing the machine. What changes is the heater specification and, when the room asks for it, the box itself.

Where it stops being fine is when the room and the catalogue do not line up: a long narrow room and the only cabin that seats enough is square, a session of ten and a cabin that seats six. Most suppliers sell their biggest unit and let you live with the gap. The third option is what this page is about.

We have in-house builders that have built massive gym saunas from scratch.

James Little, founder, PlusLife Health, 17 August 2026

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

When a catalogue cabin is right
  • The roomA rectangle with room to walk around it, access to get it in, four to six in your busiest slot.
  • The answerTake the catalogue cabin. Quicker and cheaper.
When the room needs a build
  • The roomLong, narrow, angled or low, or a session bigger than any cabin seats.
  • The answerOur in-house build team builds it from scratch to the room, by quote.

Four questions that usually settle it before you speak to anyone

Three take a tape measure, the fourth takes your timetable. Run them and you know which half of this page you are in.

01

The footprint, after clearances

Measure the space the sauna can occupy, then take off the clearance: a swinging door, a path past it, a gap behind for the wall.

A clean rectangle left over is catalogue territory; a thin strip, an L, or a rectangle with a column is not. Clearances for the unit you are quoted come in writing.

02

How many people, in your busiest slot

Not how many members you have: how many are in the sauna at once, in the slot that fills first.

Four to six is a catalogue number; ten to twelve is not.

03

The way in, and the ceiling

Measure the narrowest point from the street to the spot: gate, corridor, doorway, lift, any turn. Then the ceiling height.

A cabin that will not fit through the door is assembled inside, which changes the assembly quote.

What your electrician prices

The fourth question is power. Traditional saunas hard-wire, and the connection is made by your licensed electrician, not by us: a separate line item on any quote. Single or three phase, and where the board sits, changes the price. The requirement for the unit you are quoted comes in writing.

If the catalogue fits your room

If those four questions leave you with a room a catalogue cabin fits, take it. That is a real recommendation, not a set-up for an upsell.

Have the call anyway: a cabin on a gym floor raises the same questions a build would, heater, delivery, assembly, member flow, and you leave with a number rather than a proposal.

What "built from scratch to the room" actually means

The box is drawn to your space rather than chosen off a page, and the heater is specified for the room. Builds are quoted one at a time.

  • 1The room, measured. Footprint, clearances, ceiling, access, board, drain.
  • 2The space, drawn. The 3D floor plan with the units placed. Nothing ordered, no deposit.
  • 3The build, specified. Dimensions, benches, door and glass, ventilation, heater sized to the volume just drawn.
  • 4The quote, then the build. Delivery and assembly quoted with it. Then built by our in-house build team and assembled on site.
Where it is built

A custom gym sauna is built from scratch by our in-house build team, drawn to your floor, with the heater sized to the drawn volume.

The catalogue half is just as plain. Our traditional saunas are designed in Australia and 100% built in Europe, where sauna was born. A certificate of origin is available on request.

So how do you judge a build you cannot see? By the standard of the work. Showrooms are open by appointment: put your hands on the timber, the bench fixings, the door hardware, the way the glass sits in its frame.

A scratch build is that standard of joinery drawn to different dimensions. Then the questions, and they work on any supplier including us: the five to ask about an odd room.

What size heater does the room need?

A heater is sized to the volume it heats and the conditions it holds: change the room and you change the heater.

The short answer

Commercial-grade Harvia, built to run all day, sized to your room and your timetable, and named by make and model on your quote before any deposit.

What moves the number

Three things move the number: the volume of the cabin, the heat loss through glass and doors and how often they open, and how fast the room recovers after a group has been through. A home cabin is sized against an easy version of all three.

Tell the people on the commercial call the room and the busiest slot, and ask what it needs and why. A model number offered without a reason is not an answer, from us or from anyone.

The heater is named: Harvia

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; anyone who has one sends it the same day.

Worth knowing

Every traditional sauna can be optioned with the Wi-Fi controller, a premium applies, or comes with built-in controls, depending on the heater, with the option price confirmed on the call. Harvia is behind the app: it schedules heat-up, learns your cabin's heat-up time, and tells your phone when the sauna is ready.

Heat-up is 20 minutes to an hour on average, depending on the temperature you want. For running cost, ask for the figure for your model at a stated tariff, in writing.

Odd-shaped room, power on the far wall, drain in the wrong corner. That is what the call is for.

These stall a commercial sauna for months, and none is difficult. One short call with the room in front of you settles most of them; the rest go onto the drawing. No deposit is taken on it.

  • 1The room. Your four numbers from further up, plus any obstruction we should know about.
  • 2The timetable. Members per session, the busiest slot, and from that how many units the floor takes.
  • 3Power. Single or three phase, where the board is, and what the connection needs for the heater you are quoted, priced by your licensed electrician.
  • 4Drainage. Where the drain is, which way the floor falls, and how far the plunge sits from both.
  • 5Catalogue or build. A straight answer on whether a cabin fits, and what a build involves if not.
  • 6Delivery and assembly, quoted, with stock windows for catalogue units and a separate timeline for a build.

After the call: a 3D floor plan of your wellness space

Tell us the room and the timetable, and our team comes back with the space drawn in 3D, sauna and cold units placed. It is free because drawing the room is how we scope the job: your room with the sauna at the size it will actually be.

It is also the document a co-owner, a landlord or an accountant asks for: where it goes, what it displaces, what it costs delivered. If you are not the one who signs, it is the pack that gets it signed.

What a sauna built to the room looks like once it is running

No spec sheet shows this part, and it is the part that decides whether the money was well spent.

The box fits the wall it was drawn against: no half metre of dead floor beside it, no bench that stops two people short of the session you run, and the door swings the way the traffic goes. If a plunge went in, the chiller and external filter sit where you decided. A sauna built to the room looks like it was always going to be there.

The box fits the wall it was drawn against.

A caveat

One note on timing. The order of the work is fixed and runs longer than people expect: room measured, space drawn, units chosen, the connection priced, then stock windows or a build timeline set the date. Only the first two can start today.

Cabin list prices, and what each one covers

Cabin list prices as displayed on pluslifehealth.com.au on 13 August 2026, subject to change, not the delivered commercial number: the box under the grid says what sits outside them.

What the cabin price covers, and what it does not. The figures above are the cabin's published list price.

Outside them, and quoted on the call before any deposit: delivery, assembly on site, commercial heater specification where it differs from the standard unit, and the electrical connection, priced by your licensed electrician.

Alongside them sits the commercial support package, coverage plus scheduled maintenance, part of the answer to year three: Commercial Use Coverage at $500, maintenance packs at $440 for six months or $850 for twelve. They are cost lines: ask which apply and get the total. If an ice bath is quoted too: Commercial Ice Bath $6,730 to $7,730 and Commercial Chiller $4,950.

Why there is no all-in commercial figure here. Your room, your power, your access and your timetable set it. A custom build has no list price: built from scratch by our in-house build team, quoted to the drawn room. The delivered and assembled number is quoted on the call.

Five questions for an odd room. Take them to every supplier, ours included.

  • 1. Ask them to say plainly whether your room takes their catalogue cabin or needs a build. An L-shaped room answered with "our largest model" is not an answer.
  • 2. If it is a build, ask who builds it: their own builders, a subcontractor, or a flat pack from a factory they have not stood in.
  • 3. Ask what the heater is specified against. The volume of the room they drew and how often the door opens is an answer; the model number in the catalogue is not.
  • 4. Ask what is inside the quoted number and what is outside it: delivery, assembly, electrical, any commercial-use lines.
  • 5. Ask which warranty terms apply to commercial use, in writing on the quote. Ours are published on our website, with usage requirements for commercial settings, confirmed in writing on your quote.

Put all five to us.

When a custom build is the wrong answer

Better said here than discovered after a deposit. Three situations make a scratch build the wrong call, and we will say so in all three.

Your room takes a catalogue cabin. If the measurements work, take the cabin: quicker, comparable, and there is nothing clever about paying for a build you did not need.

Your budget is set and your date is close. A custom build is drawn, built, delivered, then assembled. It is not the fast option and we will not pretend otherwise. If the suite has to open in eight weeks, ask about catalogue units and stock windows instead.

You may not still be in this building. A sauna built to a room is built to that room. If your lease is short or a move is being discussed, a catalogue cabin that can be dismantled and moved is the better answer.

A fourth case is worth naming: a sauna may not be the right purchase for your floor this year at all, and that is a legitimate answer to come off the call with. The plan and the quote cost nothing and do not go stale. If you leave with both and a decision to buy next financial year, that is a good outcome.

Will this supplier still be here in year three? Here is what you can check.

Most operators have been ghosted by a supplier at least once. The question deserves things you can verify, not a slogan.

PlusLife Health is family-run and founder-operated, since 2021. Showrooms are open by appointment. Harvia parts sit behind every heater we specify, and the commercial support package is priced in the scope box above. The people on the commercial call have specified large commercial heaters before.

If an operator reference matters to you, ask for one on the call. And ask around: gym networks are small.

The questions gym and studio operators ask us next

Run the four questions further up this page. A clean rectangle that seats your busiest slot takes a catalogue cabin; if not, the room needs a build. Bring the numbers to the call for a straight answer.

No. These are cabin list prices: delivery, assembly, commercial heater specification, electrical and commercial-use items sit outside them, listed in the scope box above. The number to compare against another supplier's is the delivered and assembled total from the call.

From scratch by our in-house build team, drawn to your floor, heater sized to the drawn volume. Catalogue units: the whole traditional range is 100% built in Europe, and a certificate of origin is available on request.

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.

Two checks. First, a build is a bigger box with more timber, more glass and a larger heater, so the catalogue cabin nearest your capacity is an honest reference point.

Second, ask for the quote broken into lines: cabin or build, heater specification, delivery, assembly, commercial-use items. A quote you can read line by line is one you can compare, or take to a board.

Possibly, and we will say so on the call. A build earns its keep when the room genuinely will not take a cabin. If a cabin fits, that is what we will quote, and it is the cheaper answer.

The build standard is on show at a showroom, by appointment: the timber, bench fixings and door hardware a custom build is made with. The 3D plan shows your own room. Ask on the call about builds like yours.

Book a call

Bring the room. We will tell you whether the catalogue fits it.

Bring four numbers and most of it is settled in the first five minutes: usable footprint after clearances, ceiling height, the narrowest point on the way in, and how many people are in the sauna in your busiest slot.

Bring any quote you are holding and we will go through it line by line. If the cabin you have already been quoted is the right one, you will hear that.

Family-run since 2021. Showrooms available by appointment. No deposit, no obligation. The delivered number is quoted on the call.
