Sauna vs hot tub comes down to how you want to unwind and how much upkeep you will accept. A sauna is dry heat in a small cedar room: no water to treat, a heater to size and wire, and a short warm-up. A hot tub is a soak in hot water: more water care, more weight and, in a wood-fired tub, a fire to tend. Prices overlap more than people expect. Our outdoor saunas start at $5,956.50 plus a heater, and our wood-fired hot tub starts at $5,505.
"Sauna vs hot tub" and "is a sauna and hot tub combo worth it" are two of the most common questions in sauna and home-improvement forums. Here is a side-by-side with the products we sell.

Choose a sauna if...
- You want something you can use daily with no water to treat.
- You want several people at once: the Tranquility barrel seats 6.
- You are fine with an electrician running a circuit, or you want a wood stove.
- You plan to add a cold plunge later. A sauna and a plunge are the classic pairing.

Choose a hot tub if...
- You prefer floating in warm water over sitting in dry heat.
- You want no electricity at all. The Starlight heats with its own wood stove.
- You soak in the evening or on weekends and enjoy tending a fire.

Is a sauna and hot tub combo worth it?
If you have the space and budget, a combo gives you two very different ways to use the yard: dry heat in the sauna, a soak in the tub. The Starlight's white cedar skirting is designed to match the Canadian Timber saunas, so the two look like one set. Rough budget: a MiniPOD at $5,956.50 plus a Harvia KIP at $1,211, plus the Starlight at $5,505, comes to $12,672.50 before bases and installation.
Plan the layout before you order. Place both on level bases close to each other, think about the chimney of the hot tub and the sauna, and leave a path for firewood. If both use wood, you can store firewood in one place.
What about a sauna and cold plunge instead?
Many buyers end up choosing a sauna plus a cold plunge rather than a hot tub, because the plunge is smaller and cheaper. Our cedar plunges start at $2,554.50. See Baltic vs Polar vs Flow.
Sauna vs hot tub: common questions
Which is cheaper to run?
The Starlight uses firewood, no electricity. An electric sauna adds power use. Our outdoor sauna electricity cost by state study puts a typical routine at about $15.94 a month at the US average rate.
Which needs less maintenance?
The sauna. There is no water to treat. A wipe-down and fresh air after use keep the cedar in shape.
Which takes less space?
Check the footprint by model. The Starlight needs a base of at least 44 by 84 inches. Barrel saunas are 86.25 inches wide, and depth runs from 79 inches (Harmony) to 118 inches (Tranquility).
Which one should you buy?
- A barrel or MiniPOD sauna if you want daily use and low upkeep.
- The Starlight if you want a soak, a fire and no electricity.
- Both if you want a matching cedar set and have room for two bases.
