Quick Answer: A “sauna shower combo” is a prefabricated enclosure that packs a full shower and a heat chamber — wet steam or a small dry infrared nook — into one footprint, and it typically costs $4,800-$7,800 for the unit alone, or $10,000-$15,000 fully custom-installed, per Fixr and HomeGuide’s 2026 cost data. The catch buyers miss: “combo” doesn’t reliably mean simpler wiring or a full-size sauna experience. Premium dual-chamber units like Aquapeutics’ Southwood ($8,499) need two separate dedicated 240V/16A circuits, and the “sauna” side of most affordable combos is a small 1kW infrared nook, not the full-size cabin you’d get buying a standalone unit.
Search “sauna shower combo” and you’ll land on two different products wearing the same name: a genuine dual-chamber enclosure with a real sliding-door split between a steam room and a dry-heat side, or a single wet stall with an infrared heater panel bolted onto a teak bench. Neither is wrong to buy, but they solve different problems — and the marketing rarely tells you which one you’re looking at.
Sauna shower combo options at a glance
| Type | Best for | Price | Note |
|---|---|---|---|
| Dual-chamber combo (e.g. Ariel Platinum DS204F3) | Small bathrooms wanting both in one box | ~$3,000–$4,500 unit only | Sliding doors split steam side from a small infrared "sauna" nook; single 220V connection |
| Premium dual-chamber combo (e.g. Southwood) | Larger bathrooms, closer to two real rooms | ~$8,499 unit only | Needs two separate dedicated 240V/16A circuits — steam and sauna each get their own |
| Build-your-own: generator + full cabin | Anyone who wants a genuinely full-size dry sauna | Steam generator from ~$1,300 + cabin from ~$2,300+ | More install work, but no compromise on cabin size — see our best infrared sauna guide |
1. All-in-one combo units — one purchase, one footprint
Steam Shower / Infrared Sauna Combo Enclosure
- Typically around 71" x 47.6" x 87.4" — roughly the footprint of a large corner shower, per manufacturer spec sheets for this class of unit.
- Pairs a 3kW steam generator on the wet side with a smaller 1kW infrared heater on a separate teak-seat side, split by sliding glass doors rather than a full wall.
- Runs on a single 220V circuit rather than two separate dedicated circuits, which simplifies the electrical job versus a premium dual-circuit combo.

This is the unit most people picture when they search “sauna shower combo”: one prefab box, one delivery, one plumbing and electrical hookup. The trade-off is scale — the infrared side is a bench-sized nook, not a stand-up cabin, so treat it as a bonus dry-heat option bolted onto a steam shower rather than a true alternative to a dedicated infrared sauna. For context on what a full-size cabin actually delivers, see our best infrared sauna guide.
2. Premium dual-chamber combos — closer to two real rooms
Dual-Chamber Steam Shower + Sauna Enclosure
- Roughly 71" x 48" x 90", with two full hinged doors separating a genuinely distinct steam room from a genuinely distinct sauna room, per manufacturer spec sheets.
- Needs two separate dedicated 240V/60Hz/16A circuits — one for the steam generator, one for the sauna heater — because underneath the shared shell, it's still two full appliances.
- Fully custom-installed versions of this tier, with tiling and structural work included, run $10,000-$15,000 total per Fixr/HomeGuide cost data, versus $4,800-$7,800 for a prefab unit alone.
The honest pitch for this tier: you’re not buying a simpler install, you’re buying a smaller footprint than two fully separate builds would need. The electrical scope is the same two circuits a standalone steam generator and standalone sauna heater would each require on their own — the combo just houses both behind one set of doors instead of building two rooms. That’s a real space win in a tight bathroom, just not the wiring shortcut the word “combo” implies.
3. Build it yourself — a generator plus a real cabin
If floor space isn’t the constraint, skip the combo box entirely. Add a steam generator to your existing shower — our best MrSteam sauna guide covers Amazon-purchasable units from about $1,300 for the generator alone — and put a genuine full-size infrared cabin somewhere else in the house, starting around $2,300 for a 2-person model per our best infrared sauna guide. You’ll do two separate electrical and plumbing jobs instead of one, but neither experience gets compressed to fit inside a single shared footprint. Our best steam sauna guide breaks down the full generator-only cost range if you want the wet side without any sauna component at all.
The honest answer on what “combo” gets you
A sauna shower combo is a genuine space-saver when a bathroom can’t fit two separate builds, and the $4,800-$7,800 equipment cost is often less than plumbing and wiring two rooms from scratch. What it doesn’t reliably deliver is either a wiring shortcut — premium dual-chamber models still need two dedicated 240V circuits — or a full-size dry-sauna experience, since most affordable combos scale the infrared side down to a bench-sized nook. Know which trade-off you’re making before the unit arrives: floor-space savings, yes; simpler electrical or a genuinely large sauna cabin, usually no.
The bottom line
Tight on space and want one purchase? A dual-chamber combo enclosure (about $3,000-$4,500, single 220V circuit) covers both a real steam shower and a bonus infrared nook. Want two rooms that feel genuinely separate, and have the bathroom footprint for it? The premium dual-chamber tier (about $8,499 unit, two dedicated 240V circuits) gets closer, at a real cost and wiring premium. Want a full-size sauna experience with no compromise? Skip the combo and build a steam generator into your existing shower plus a standalone cabin elsewhere — see our best infrared sauna and best MrSteam sauna guides for current picks.
