The brand comparison covers which sauna to buy. This is the piece to read before you actually order one — because the single most common regret in this category isn’t picking the wrong brand, it’s not measuring the room, the electrical panel, or the delivery path first. Every brand above ships a genuinely good product; a bad installation experience is almost always a planning problem, not a product problem.
Electrical requirements. This is the detail that catches the most buyers off guard, and it varies more than people expect between infrared and traditional saunas. Most 1-2 person infrared cabins run on a standard 120V/20A circuit — often the same outlet a large appliance would use. Larger infrared cabins (3+ person) and nearly all traditional/steam saunas need a dedicated 240V circuit, frequently in the 30-50 amp range depending on heater size. Sun Home’s new Nova line, built around a HUUM heater, is a traditional sauna and should be assumed to need a dedicated 240V circuit unless the spec sheet says otherwise. Confirm the exact electrical spec for your specific model before you order — don’t assume based on a different model from the same brand — and if you’re not already running a dedicated circuit to the install location, budget an electrician into the total cost, not just the sauna price.
Ceiling height and footprint. Most cabin saunas need 7-7.5 feet of ceiling clearance minimum, and custom builds from a company like SaunaCloud can be built to fit tighter spaces than a fixed-SKU cabin can. Footprint scales with person-capacity in a fairly predictable way — a 2-person unit is typically workable in a spare bedroom corner or basement bay, while a 4-6 person cabin (like Sun Home’s larger Eclipse or Luminar units) needs a genuinely dedicated room. Measure the exact floor footprint from the manufacturer’s spec sheet, not a generic “sauna size” figure — cabin dimensions vary meaningfully between brands even at the same stated capacity.
Flooring. This is where infrared and traditional saunas diverge the most. Infrared cabins are dry-heat and don’t require drainage — a level, stable floor (concrete, tile, or reinforced wood subfloor) is sufficient. Traditional and steam saunas involve real moisture and occasionally direct water contact, and genuinely benefit from a moisture-resistant floor with drainage, especially for an indoor install. If you’re installing a traditional sauna indoors without existing drainage, factor that into your renovation budget before you buy the unit, not after it’s sitting in a box in your garage.
Ventilation. Every sauna needs a functioning intake-and-exhaust airflow path to perform as designed and to keep the heater from working harder than it should — this is true for infrared and traditional units alike, though traditional saunas with higher humidity have less margin for error. Manufacturer install guides specify vent placement; don’t skip this step because the cabin “looks sealed enough.” Poor ventilation is a common, avoidable cause of both uneven heat and premature component wear.
Delivery-path clearance. Cabin saunas ship as large panelized crates, and a custom build from SaunaCloud may arrive as raw framing and cedar material rather than a pre-built cabin — either way, something large and heavy has to physically get from a delivery truck to the install room. Measure doorways, stairwells, and any tight turns between the entry point and the install location before you order. This matters even more for a finished-basement install, where a beautiful room that the panels can’t actually reach is a real, recurring problem in this category — not a hypothetical one.
Indoor vs. outdoor placement. An outdoor-rated sauna (like Sun Home’s Luminar or Clearlight’s Outdoor line) needs its own foundation or pad, weatherproofing considerations, and — depending on your municipality — may require a permit the way a shed or small structure would. Check local code before you commit to an outdoor placement; this is one of the few checks on this list that can actually block a purchase entirely if the property doesn’t allow it, rather than just adding cost.
Professional installation vs. DIY assembly. Most fixed-SKU cabin saunas (Sunlighten, Clearlight, Sun Home) are designed for owner assembly with basic tools and typically ship with instructions and support documentation — genuinely doable for a reasonably handy buyer over a weekend. A custom build from SaunaCloud is a different scope entirely and assumes either professional installation or a serious DIY renovation project, not an afternoon assembly. Confirm which category your chosen brand and model falls into before you assume a delivery date is also a “sauna is running” date.
Pre-Order Checklist
| Item | What to Confirm |
|---|---|
| Electrical | 120V/20A for most small infrared units; dedicated 240V circuit for larger infrared and nearly all traditional saunas — confirmed against your exact model’s spec sheet |
| Ceiling height & footprint | 7-7.5ft minimum clearance; exact floor footprint matched to your chosen model, not a generic capacity figure |
| Flooring | Level and stable for infrared; moisture-resistant with drainage for traditional/steam, especially indoors |
| Ventilation | Intake-and-exhaust airflow path installed per the manufacturer’s own guide |
| Delivery path | Doorways, stairwells, and turns measured against the panelized crate or framing materials’ dimensions |
| Outdoor placement (if applicable) | Foundation/pad, weatherproofing, and local permit requirements confirmed before ordering |
If your space checks out against all six, you’re ready to move from planning to actually ordering — go back to the brand comparison to pick which of the four fits your space and budget, or revisit the original buying guide if you’re still deciding how much to spend in the first place.
