Steamist (Delta SteamScape)
Steamist SM Plus SMP-7 Steam Shower Generator
Steamist is the other legacy American steam name — now also sold under Delta's SteamScape branding after acquisition, a detail worth knowing when comparing listings — and the SM Plus SMP-7 is its 7.5kW mid-size generator at about $2,600. The engineering pitch is SteadySteam, which modulates output to hold your set temperature instead of the blast-and-coast cycling cheaper generators do, plus a stainless tank and a sub-gallon water draw per 20-minute session. Plumbers and owners rate the brand's reliability alongside Mr.Steam, with the choice often coming down to which controls ecosystem (TotalSense vs. iSteam) and which dealer you like. All the steam-category realities apply: the enclosure build is the real project and the real budget, hard water is the enemy, and r/Sauna will remind you — accurately — that a steam shower is a different pleasure than sauna, not a substitute.

More from Steamist (Delta SteamScape) →Cross-shoppers land here after realizing their dream isn't dry 195°F air but a 115°F fog you can barely see through — a steam shower, and Mr.Steam is the name-brand way to build one. The eSeries MS90EC1 is the residential workhorse: 5kW, sized for tiled enclosures up to 71 adjusted cubic feet, about $1,799 at big-box retail for the generator. The critical education, which r/Sauna delivers bluntly in every crossover thread: steam and sauna are different animals (100% humidity at ~110-120°F versus dry 180-200°F), and the generator is the cheap part — a properly vapor-sealed, sloped-ceiling tiled enclosure plus plumbing and electrical routinely runs $5,000-$15,000 in renovation. Owners of finished installs love them daily; the horror stories are all botched enclosures, not failed generators. Buy controls, AromaSteam head, and AutoFlush as a package; à la carte pricing stings.
Golden Designs (Maxxus)
Maxxus Trinity 3-Person Corner Infrared Sauna
The Trinity is Golden Designs' clever-footprint play: a corner-format three-seater at $2,699 (list $3,833) that tucks into the dead angle of a garage gym or basement where rectangular cabins won't fit. The 'Dual Tech' pitch mixes seven ceramic and carbon emitters — ceramic runs hotter and more focused, carbon spreads gentler warmth — plus a floor reflexology heater, red-light chromotherapy, and Bluetooth. Owners report it as a meaningful step up in heat intensity from all-carbon budget boxes. The same house caveats as its Dynamic siblings apply: 'low-EMF' is the marketing tier below the brand's own 'Near Zero' models (which quote under 3 mG only when measured inches from panels), warranty terms shift by retailer, and the hemlock paneling is budget-grade. r/Sauna's take on the whole Golden Designs catalog: functional sweat boxes, priced honestly, marketed optimistically.
The Cilindro is the heater r/Sauna upgrades to when they stop asking 'which sauna should I buy' and start asking 'how do I get better steam.' The open-grate pillar holds roughly 200 pounds of stone — triple a wall heater — so you can ladle water down the sides for soft, rolling steam or on top for a sharp blast. This $3,084 package from a US Harvia dealer bundles the PC90E, WiFi Xenio controller, and the full stone load, which matters because buying stones separately surprises people. Owners' honest notes: 200 lb of stones means a real floor and a patient first heat-up (the mass takes longer than a KIP), the MyHarvia app occasionally drops offline, and you need genuine 280+ cubic feet — in a small room it's overkill that short-cycles.
Golden Designs (Dynamic)
Dynamic Barcelona 1-2 Person Low EMF Infrared Sauna
The Barcelona is America's default budget infrared — the Costco-and-Amazon staple at $1,899 (frequently less on promotion) that has introduced more households to home heat therapy than any premium brand. Canadian hemlock panels click together in an afternoon, it plugs into a normal wall outlet, and it does what owners want: 20-minute sweats with Bluetooth playing. Now the honest part the listings gloss: retailer specs admit the standard model's 'low-EMF' means 5-10 mG measured a few inches from the panels — an order of magnitude above Clearlight's sub-1 mG — and the $2,299 'Elite' exists precisely to fix that. Max temps hover around 140°F, walls are thin, and r/Sauna's verdict is a shrug: 'it's a warm box, and for $1,900 that's fine.' As a first step into IR with modest expectations, it earns its 900+ reviews.
SweatTent
SweatTent Wood-Fired Sauna Tent
The SweatTent is the budget option r/Sauna actually respects, because it cheats none of the physics: a $1,499 pop-up tent with a real wood-burning stove and stones on top, hitting a legitimate 200°F with water-on-rocks löyly — hotter than any infrared cabin at any price. The 300°F-rated Oxford nylon shell sets up in under ten minutes, needs zero electrical work, and travels to campsites. Reviewers call it the best sub-$2,000 sauna experience sold. The honest running costs and quirks: firewood (SweatTent's own bundles run $50 for 4-6 sessions), 20-30 minutes of stove-tending before it's hot, condensation dripping from the ceiling in cold weather, and a fabric shell that is ultimately consumable — years, not decades. No HOA will mistake it for landscaping. As a first real sauna or a cabin-property rig, it's the community's default budget answer.
Amerec is the American commercial-sauna stalwart — the heaters in a thousand gym saunas — and the Designer B is its residential wall unit, running about $1,400 street for the 8kW with built-in vulcanite rocks and mechanical controls. Like the Harvia KIP, this is a heater for people building their own room, and r/Sauna treats the two as interchangeable answers: buy whichever is cheaper the week you're shopping. Owners like the commercial-duty elements and the dead-simple time/temp knobs; the practical knocks are the same as every wall heater — modest stone capacity means sharper, shorter steam than a pillar heater, and the included vulcanite rocks are serviceable but many owners swap in proper olivine stones. US-based parts and support is a quiet advantage when an element dies in year six and you want a replacement without importing anything.
