3-Person vs 4-Person Infrared Sauna: Which Size Do You Actually Need?

Between a 3-person and a 4-person infrared sauna, the step up is much smaller than most people expect. The Bergamo Elite 4-Person ($3,999) is 70" wide x 42" deep x 75" high. The Lugano Elite 3-Person ($3,499) is 60" wide x 45" deep x 75" high. That is ten inches of extra wall, and the 4-person is the shallower of the two.

Both run on a standard dedicated 120V / 20A circuit. Both are Canadian Hemlock with ultra low EMF FAR infrared carbon panels and a 5-year warranty. Both ship free curbside in three boxes and clasp together without tools. Going from three seats to four does not change the wiring, the ceiling height, or the assembly.

So the decision is not really about size. It is about which wall you have: if you are short on width, a 3-person fits. If you are short on depth, the 4-person Bergamo Elite is the one that fits.

Every figure above is taken from the manufacturer's spec sheet for each model. All three are indoor residential saunas.

Most people measure the wall they want the sauna against and stop there. The number that actually kills installs is depth, because depth is what pushes the cabin into the walkway.

Here is where the spec sheet surprises people. The Lugano Elite is 45" deep. The larger-capacity Bergamo Elite is 42" deep. Add the 4.3" roof overhang that both carry and the Lugano Elite occupies roughly 49" of floor-to-wall depth against the Bergamo Elite's 46". If your room is tight front-to-back, the 4-person model is the one that fits, and it costs $500 more for an extra seat.

The Toscana Elite is the space-efficient 3-person: 60" x 42", the same depth as the Bergamo Elite in a narrower cabinet. It is the pick when you have exactly a 5-foot wall to work with.

Three practical numbers to check before you order:

• Ceiling: all three are 75" tall. Any standard 8-foot ceiling clears easily; a finished basement with ductwork may not.
• Clearance: leave a few inches behind and beside the cabin for airflow and for the door swing at the front.
• Path in: the sauna arrives as three boxes on an LTL pallet, so the panels come through your doorway flat, not as an assembled cabin. Sauna weight is 350 to 410 lbs assembled.

No. This is the single most common reason people talk themselves out of the larger cabin, and it does not apply here. The Lugano Elite and the Bergamo Elite both call for a dedicated 120V / 20A circuit; the Toscana Elite calls for a dedicated 110V / 20A receptacle. Those are the same class of circuit.

"Dedicated" is the word that matters, not the size. It means the sauna gets its own breaker rather than sharing one with the rest of the room. If you are already planning that circuit for a 3-person, you are already done planning for the 4-person. There is no 240V step, no subpanel, no service upgrade in this size range.

If you want the full picture before you call an electrician, we wrote a separate walkthrough on whether infrared saunas need special wiring.

On price per seat, the 4-person wins clearly. The Bergamo Elite works out to about $1,000 per seat, against roughly $1,166 for the Lugano Elite and $1,233 for the Toscana Elite. It is the best per-seat value in the indoor infrared lineup.

The honest caveat: per-seat value only counts if the seats get used. Manufacturer capacity ratings measure bench length with everyone sitting upright, shoulder to shoulder. In real, comfortable use a 3-person seats two adults with room to spread out, and a 4-person seats two or three comfortably or four for a shorter session. Nobody has ever regretted the extra bench room. Plenty of people have paid for seats that stayed empty.

A reasonable way to decide:

• Pick a 3-person if it is one or two regular users, your width is capped near 60 inches, or you want the Lugano Elite's extended bench so a single person can lie back and stretch.
• Pick the 4-person Bergamo Elite if three or more people in the household will actually use it, you host recovery sessions, or your constraint is depth rather than width.

If you are further down the range and weighing a 2-person instead, the 2-person vs 4-person size guide covers that end, and Cardoba Elite vs Bergamo Elite compares the two directly.

It is worth being clear about what the size decision does not affect, because it removes most of the anxiety from the choice.

• Heat quality: all three use PureTech ultra low EMF FAR infrared carbon heating. The larger cabin has more panel area for its volume, not a different technology.
• EMF: all three are rated ultra low, 3-5MG at 2-3 inches from the panels.
• Materials: Canadian Hemlock with a honey dark stain across the board, with a tempered glass door.
• Features: interior chromotherapy LED lighting, Bluetooth audio with built-in speakers, and a digital LED control panel on all three.
• Warranty and delivery: 5 years, and free curbside freight on every model.
• Assembly: clasp-together, no tools required, on all three.

You are choosing a footprint and a bench, not a better or worse sauna.

Is a 4-person infrared sauna much bigger than a 3-person?

Less than most people expect. The Bergamo Elite 4-Person is 70" wide x 42" deep x 75" high and the Lugano Elite 3-Person is 60" wide x 45" deep x 75" high. That is ten inches of extra width, the same height, and the 4-person is actually three inches shallower. If your constraint is depth rather than width, the 4-person model is the one that fits.

Does a 4-person infrared sauna need a bigger electrical circuit than a 3-person?

No. The Bergamo Elite 4-Person and the Lugano Elite 3-Person both call for a dedicated 120V / 20A circuit, and the Toscana Elite 3-Person calls for a dedicated 110V / 20A receptacle. There is no 240V step and no subpanel in this size range. The requirement that matters is that the circuit is dedicated to the sauna rather than shared with the rest of the room.

How many adults really fit in a 3-person infrared sauna?

Capacity ratings measure bench length with everyone seated upright and shoulder to shoulder. In comfortable real-world use, a 3-person seats two adults with room to spread out, or three for a shorter session. The Lugano Elite's extended bench also lets a single user lie back and stretch, which is the main reason people choose it over the narrower Toscana Elite.

Which is better value, the 3-person or the 4-person?

On price per seat the 4-person Bergamo Elite wins at about $1,000 per seat, against roughly $1,166 for the Lugano Elite and $1,233 for the Toscana Elite. That only counts if the seats get used, so the value question is really how many people in your household will realistically sauna together.

What is the difference between the Lugano Elite and the Toscana Elite?

Both are 3-person ultra low EMF models at 60 inches wide. The Lugano Elite is $3,499 with a 45-inch depth and an extended bench built for stretching out. The Toscana Elite is $3,699 with a shallower 42-inch depth, 8 PureTech 360 carbon heat emitters, a removable bench, and interior chromotherapy with a red light feature. Choose the Lugano Elite for bench room and the Toscana Elite for a tighter footprint.

Do these saunas ship free?

Yes. All three ship free with curbside delivery, arriving as three boxes on an LTL pallet, and all three assemble with clasp-together panels that need no tools. Assembled weights run from 350 lbs for the Lugano Elite to 410 lbs for the Bergamo Elite.

Can I finance a sauna in this price range?

Yes. 0% APR financing is available at checkout, subject to approval, so the monthly difference between a 3-person and a 4-person model is smaller than the sticker gap suggests.

If you have the room dimensions and still cannot call it, that is the normal place to get a second opinion rather than a sales pitch. Use the sauna finder to filter by capacity and budget, or text a specialist at (623) 300-0464 with your wall measurements and how many people will use it. We will tell you if the smaller one is the right answer.
