Vindar vs Northwood: Comparing Two Sauna Aromatherapy Diffusers

Ever since I wrote about the Vindar red cedar aromatherapy bowl on this site, the question I get most often is some version of, what about the stone ones. There's a whole category of aromatherapy stone cups on Amazon, usually sold under names like Northwood, and they look almost like little soapstone bowls with a polished finish. My neighbor Denise bought a Northwood stone for her infrared cabin about four months ago, and when she mentioned she liked it, I asked to borrow it for six weeks to run it in my own sauna alongside the Vindar bowl I already knew well.

Short answer first, since I know a lot of readers just want the verdict before the details: the Vindar cedar bowl wins on scent throw, overall value, and general fit for a wood sauna like ours. The Northwood stone holds its own on heat retention and simple cleanup, and it looks a little more modern if that matters to your setup. Neither one is a bad choice, but after six weeks of running both, I'd buy the Vindar again without much hesitation.

For context on how I got to that verdict, I ran the Vindar bowl for the same three to four sessions a week my husband Mark and I always do, then swapped in the Northwood stone for six straight weeks, same bench spot, same eucalyptus oil, same time of evening. I used a kitchen timer to track how long the scent stayed noticeable each session, kept an eye on how each one handled repeated heat cycles, and paid attention to the small habits that build up around using either one, since that's where the real differences tend to show up, not in the first session but somewhere around the twentieth.

Where Vindar Wins

The biggest gap I noticed between the two showed up in how long the scent actually lasted once I added oil and sat down. With the Vindar bowl, four or five drops of eucalyptus gave me a noticeable scent for a solid eighteen to twenty minutes, tapering off gradually rather than dropping off a cliff. The Northwood stone, using the same amount of oil, peaked faster and noticeably faded by the ten to twelve minute mark. My best guess is that the cedar actually absorbs a thin layer of oil into the wood grain and keeps releasing it slowly as it warms, where the stone's smooth surface just lets the oil sit on top and evaporate at a steadier, quicker clip.

Price is the other clear advantage. The Vindar bowl typically runs somewhere around $22 to $28, while the Northwood stone I borrowed from Denise cost her closer to $34 when she bought it. That's not a massive gap on its own, but across a purchase this small, it's a meaningfully better value, especially once you factor in that the cedar bowl also gave us longer scent duration per session. Paying more for less scent throw is a hard case to make, even setting the aesthetic question aside entirely.

Then there's the simple matter of how it looks and feels sitting on the bench of an actual wood cabin sauna. The Vindar bowl's grain and warm reddish tone genuinely blend into the cedar walls and bench around it, so it reads like part of the room rather than an accessory someone set down. The Northwood stone, polished and a little cooler in tone, stood out more against the wood, which some people might actually like, but for our cabin it always looked slightly out of place, like a piece of kitchen decor that wandered in from somewhere else.

I'll also say the Vindar bowl felt more forgiving day to day. Because it's light and shallow, it's easy to top off with just a couple of drops without worrying about overfilling, and it dries out completely between sessions if we skip a few days, no lingering dampness. The Northwood stone's deeper cup meant I sometimes added too much oil out of habit, since the bowl looked emptier than it was, and a couple of times I ended up with more scent than I actually wanted in the first five minutes of a session.

One more small thing that added up over six weeks: the Vindar bowl never once needed anything beyond a soft cloth and my regular weekly wash to keep smelling clean and neutral before switching oils. Mark noticed the difference too, since he's the pickier one about scent in our house, and he mentioned more than once that the cedar bowl felt like it was doing more work with less oil than the stone cup managed, which lines up with exactly what my timer kept telling me session after session.

By the fourth week of the swap, I could genuinely tell which one was on the bench without looking, just from how the sauna smelled ten minutes into a session. With the Vindar bowl, the eucalyptus was still present and easy to pick out. With the Northwood stone, that same ten minute mark already felt like the scent was fading into the background, which told me the difference I noticed in week one wasn't a fluke of a fresh bottle of oil but a real, repeatable pattern in how the two materials behave.

Where Northwood Wins

I want to be fair to the Northwood stone, because it does have a real strength, and it's the one thing that impressed me most during the six weeks I ran it. Stone holds heat far longer than cedar does. After a session ended and the cabin started cooling, the Northwood cup stayed warm to the touch for a good ten to fifteen minutes longer than the Vindar bowl, which cooled almost as fast as the room around it. If you like lingering in the sauna as it cools down, or you tend to sit in there a while after the heater shuts off, that extended warmth kept a faint trace of scent present longer into that wind-down period, even though the initial throw wasn't as strong.

Cleanup was also genuinely easier with the stone. Because oil sits on the polished surface rather than soaking into it the way cedar absorbs oil, a quick rinse and wipe left the Northwood cup looking essentially new every time, with no buildup, no gummy residue, and no gradual darkening of the interior the way I've watched happen with the Vindar bowl over months of use. If low-maintenance matters more to you than peak scent throw, that's a real point in the stone's favor, and it's the reason Denise says she'll probably stick with hers.

The extra weight of the stone cup also meant it never once tipped over on the bench, even when I reached past it for a towel the way I've accidentally knocked the lighter Vindar bowl before. If your sauna bench has any slope to it, or you're setting the bowl somewhere with a bit more foot traffic around it, that added stability is worth something. It's a small thing, but small things are exactly what separate two products that otherwise do a similar job.

Denise also pointed out that the Northwood stone never picked up a lingering background scent the way our cedar bowl has, even after just her four months of steady use. If you like rotating between several different oils and want each session to start from something closer to a neutral slate, the stone's nonporous surface handles that better than cedar ever will, since the wood tends to hold onto whatever you use most often.

Who Should Buy Which

If you have a wood cabin sauna like ours and you want the scent to actually carry through most of a twenty to thirty minute session, the Vindar cedar bowl is the better everyday choice. It costs less, it matched our décor better, and it simply delivered more noticeable aroma per drop of oil than the stone cup did in our side-by-side test. It's also the one I'd recommend if you're just starting out with sauna aromatherapy and don't want to spend much to find out whether you'll actually stick with the habit.

The Northwood stone makes more sense if you have an infrared cabin or a more modern-looking sauna where a polished stone accessory fits the aesthetic better than raw wood, or if you're someone who lingers in the sauna well after the heater shuts off and wants that lasting warmth to carry a faint scent a little longer into the cooldown. It's also worth considering if low-maintenance matters more to you than maximum scent throw, since the easier cleanup is a genuine, if smaller, advantage. Either way, spend a little time figuring out how you actually use your sauna, daily quick sessions versus longer lingering ones, before deciding which trade-off matters more to you.

How often you actually use your sauna matters more here than most buying guides admit. If you're in there most evenings the way Mark and I are, that eighteen to twenty minute scent window on the Vindar bowl adds up to a noticeably better experience across dozens of sessions a month, and the lower price means you're not paying extra for the privilege. If your sauna sessions are more occasional, once or twice a week, the gap between the two matters less, and the Northwood stone's easier upkeep might tip the decision in its favor simply because you won't be building a weekly cleaning habit around it.

My honest take after six weeks of running both side by side: the Vindar bowl's lower price and stronger, longer-lasting scent throw make it the smarter buy for most home sauna setups, especially anything built from wood. I'd only steer someone toward the Northwood stone if the modern look genuinely matters more to their space than the aroma does, or if they've already decided low-maintenance cleanup outweighs a few extra minutes of noticeable scent per session. For our cabin, and for most readers who write in asking, the cedar bowl is still the one I'd tell them to buy first.
