HUUM Drop Electric Sauna Heater

(5 customer reviews)


Water and heated stones are the essence of sauna.  Drawing inspiration from a single drop of water, the HUUM DROP is designed to elevate the beauty and performance of these core elements.  We think of HUUM DROP as a very functional piece of art, but it’s also been a reward-winning heater in since 2013.

And with the new heating element retainer, upgraded rocks, and integrated heat shields the HUUM DROP is better than ever.

We recommend using these rounded stones in HUUM heaters to complement the design and have milder steam. We supply more than enough sauna so you can always find that perfect fit. If they settle or crumble we’ll send more for an entire year.

What makes a really great electric sauna heater?

Let’s Make Sure Your Sauna Rocks

Large stone capacity is a major factor. Without a lot of rocks, the sauna can feel harsh. Rocks provide a ‘softer’ heat that will leave you refreshed instead of depleted after the sauna.

HUUM thinks you should leave the sauna feeling better than you entered it, and large rock capacity is how they do it.

HUUM DROP’s massive 122 lbs of rocks is more than any wall-mounted sauna heater on the market.

And it’s not just about making the experience more comfortable and enjoyable – more rocks also can create more steam.

A lot more steam.

Other sauna heaters need to recover after pouring a ladle of water on the rocks.  You can keep going with HUUM heaters, usually until the room is filled with steam.

It’s really a fun experience for the whole family.

But don’t more rocks take longer to heat the sauna room? 

Yes.  But it’s worth it.  And with HUUM’s Wi-Fi enabled UKU controller it’s really not a big deal.  Now you can turn on your sauna from the gym, office, or from bed.

Or program it to run at certain times on certain days.  The HUUM Apple and Android App will always keep you alerted and let you know when your sauna is ready to use.

The more you sauna, the better you will feel.  A convenient app is underrated and can make all the difference.

But large stone capacity and a user friendly app aren’t the only things that set HUUM apart.


Quite simply, HUUM electric sauna heaters get much hotter than any other professional electric sauna heater in North America.  It’s as simple as that, and it’s not disputed.

The reason is that while other sauna companies list their products to UL safety standards, HUUM chose to list with SGS standards.  Both are completely acceptable in the US and we’ve never heard of a single building inspector or insurance company having the slightest issue with them (as the other companies want you to believe).

The result is this:

Other sauna heaters have a maximum sauna temperature of 194°F at the ceiling above the heater.

That may sound like plenty of heat.  Maybe you like temperatures of 180°F and think that doesn’t matter.

But it does.

Some saunas will struggle to reach temperatures over 170°F at the bench position when the temperature sensor above the heater reaches 194°F.

Trust us, that’s a frustrating problem!

HUUM has a max programmable temperature of 230°F which will let almost any sauna get where you want to go.

A side benefit of SGS listing is that the HUUM controller can operate continuously for 12 hours, while others have a maximum of one hour.

So HUUM DROP electric sauna heaters have best-in-class rock capacity for a softer, more mild steam.  They also have a reliable, easy to use Wi-Fi app and controller and get the sauna much hotter.

The crazy thing is, in our experience that’s not even why most people buy the HUUM DROP.

Sauna Aesthetics Matter

Don’t feel ashamed of choosing the HUUM DROP for it’s minimalist good looks.  When sweating on the bench, you’ll want something nice to look at.

In our opinion, nothing photographs as good as a HUUM.  And with the stainless steel grate, it will look good as new almost forever.

Options and Sizing

The HUUM DROP comes in sizes ranging from 4.5 kW to 9 kW, catering to a variety of sauna room sizes from 106 cu. ft. up to 618 cu. ft.

Insulation, glass, and climate should be considered in sizing your HUUM DROP.

Undersizing the heater will make the elements work too hard, and it will take longer to heat the room.

Oversizing the heater can reduce the steam potential of your heater, as the room will actually reach your desired temperature before the rocks fully heat up.

HUUM is one of the most innovative and original sauna heater manufacturers specializing in both electric heaters and wood fired sauna stoves.  They kicked off a massive sauna manufacturing revival in Estonia that is now rivaling Finland for global market share. What sets HUUM sauna heaters apart in North America is they listed to SGS standards instead of UL standards.  What's the big deal? UL standards make it difficult to get the entire sauna room hot enough.  As a result, HUUM heaters are still safe but can reach temperatures up to 230°F and be programmed for 12 hours. Other professional sauna heaters in North America have a maximum temperature of 194°F above the sauna heater.  For some saunas that means it will struggle to reach 170°F at the seating position. The large rock capacity in all HUUM sauna heater models create a 'softer' steam that doesn't feel harsh light heaters with more radiant heat and less rock capacity. Their Wi-Fi capability and UKU wall controller are intuitive, reliable, and easy to use. Oh, and the aesthetics aren't bad, either!
