The HUUM STEEL Electric Sauna Heater is a slim and space-efficient unit with remarkably small safety distances, making it perfect for saunas with limited space. Thanks to its well-optimized structure, the safety distances from the walls are brought down to just 2" (5 cm) with smaller models and to 4" (10 cm) with larger models. The STEEL Mini heater also comes in an even slimmer 3.5 kW wall-mounted model which is particularly suitable for very small sauna rooms.

Because of its intelligent design, the STEEL has a much higher stone capacity than other similar sized heaters. This provides a more consistent steam and higher heat. Everything you need for an elevated sauna experience. 

The HUUM STEEL is made of durable stainless steel, ensuring years of use and it comes with a 5 year warranty. 

UKU Controllers

The STEEL is controlled by the elegant UKU Controller (required for operation), in your choice of 9 different finishes. Choose from these options in either a locally controlled or WIFI enabled controller for remote use--heat up the sauna from your car on the way home!

The STEEL requires 331 lbs of stones. We recommend any type of igneous stones 5-10cm in size, or you can purchase 10 boxes of HUUM High Quality Olivine Stones which are collected in Finland.

Add the HUUM STEEL Safety Rail for added safety and an aesthetic touch.

              Great Bulk Pack of Disposable Spoons for Everyday Use
              The Amazon Basics Disposable Everyday White Spoons are a very practical and affordable option for parties, offices, events, break rooms, or everyday household use. The large 1000-count pack is especially convenient because it lasts a long time and helps reduce the need for constant restocking. The spoons are lightweight but still sturdy enough for most everyday foods like cereal, yogurt, desserts, soups, and side dishes. They don’t feel overly flimsy for normal use, which is important for disposable utensils. I also like the clean white design because it works well for casual gatherings, parties, school events, picnics, and office lunches. Having such a large quantity on hand is very helpful for busy households or larger events. The spoons are individually easy to grab and separate from the bulk packaging, making storage and use simple and convenient. Overall, this is a reliable and cost-effective bulk pack of disposable spoons that works well for everyday meals, gatherings, and large events.

              Bulk spoons finally broke my bad habit
              We used to grab those little 20 packs from the grocery store every couple weeks and it felt like I was always running out at the worst time. When I saw this giant box I got pretty stoked and pulled the trigger right away. They are exactly what you would expect from basic disposable spoons. Solid enough for everyday stuff like yogurt, ice cream, or takeout without bending too much. Nothing fancy but they get the job done every time. At about three cents each it feels like a much smarter way to buy them. Now that we have a thousand of them sitting in the pantry I catch myself using them way more often instead of washing silverware for small snacks. This box should easily last us a couple years and I am already glad I do not have to make those annoying little trips anymore.

              BIG box of spoons
              This is one big box of white plastic spoons. Probably more than you need for home use. I’ll probably end up donating most of these to my kid’s school for the teachers lounge. The spoons are not packaged in smaller boxes or bags inside. The quality is pretty good for “everyday” spoons. Compared to the spoons I get at my local grocery store which feel more like premium plastic ware, these are smaller and made of a softer plastic. I wouldn’t call them flimsy, but they are definitely not as sturdy as the other spoons. As far as value goes, I don’t think you can find a better deal for bulk plastic spoons (currently about $30 for 1000)

              Huge box of spoons that actually hold up!
              My patience started wearing thin as a result of having to always keep buying spoons due to all the cereal and yogurt that the volunteers have each morning. Finally, I decided to buy these gigantic boxes just to be over with it once and for all. These spoons are surprisingly durable given the extremely low price and the fact that they are just disposable plastic utensils. I tried using one on some dense frozen ice cream yesterday evening, and the handle did not even flex at all, let alone break. This product comes packaged in a fairly frail cardboard box which makes it occupy quite a bit of floor space in the pantry. Nevertheless, I find it completely worthwhile.
