We require a $200 deposit to get on our list, with the balance payable upon shipment or pick-up.  Lead times do fluctuate, but they have typically been about a month.  We currently accept credit cards, cash, check, wire transfers, and some mobile payments.

We ship factory direct all over the world.  Your options are residential with lift-gate service to the end of your driveway or to a commercial location that has either a loading dock or forklift.  The commercial route normally saves $100+.  For residential delivery, you need to have room for a 53-foot semi-tractor trailer to have easy access.  

When shipped outside of Minnesota, there are no sales taxes.  For sauna stoves, we charge a $50 crating fee + shipping (typically $250-$450).  We regularly ship to Canada but require the customer to provide the broker.

Optional Extras (à la carte) 

$135 – Throat Extension 8″
$150 – Throat Extension 12″
A throat extension (also known as a through-wall) is a great option if you wish to feed your sauna stove from your changing room or from outside the sauna building.  We offer an 8″ throat (as installed on the stove in this picture or a 12″ (standing next to the stove).  12 inch is normally used for log cabins or rock foundations that are extra thick.  It is a very good idea to also add an ash-pan option if you use a throat extension to make it easier to remove the ashes.

**No Throat Extension available on small sauna stoves.  If you want to do an external feed you need to go up to a medium, because you lose 25% of your heat with the external feed.**

$165 – Ashpan
Ashpan clean-out.  Includes a slide-out ash pan with a cast iron ash grate.  Ash removal made simple and clean.

$370 – Hot Water Coil
The hot water coil gets mounted to the side of the Kuuma Sauna Stoves. This coil can be mounted on either side – please specify which side when you order.

The hot water coil is then covered with an exterior shield.  Simply solder 3/4 inch copper fittings to attach to your hot water system.

$325 – Glass Viewing Window
Ceramic window easily resists heat and tends not to attract black soot. Window size is 5″ x 8″.

If needed it’s easy to clean by dipping a wet rag into ash located in either the firebox or ashpan and wiping followed by drying with a paper towel.  

$85 – Single Heat Shield
$95 – Extended Heat Shield
Heat Shields are available for the sides and back on all sizes of Kuuma Sauna Stoves.  They simply hang on steel tabs from the top edge of the stove.  See clearance information under the FAQ’s below.

12 gallon tank fits small and medium Kuuma.  16 gallon tank fits the large Kuuma.

Frequently Asked Questions-

Is the metal heavy enough to prevent warpage?

Yes, under normal operation.  It’s constructed of 1/4″, 3/8″, and 1/2″ plates.

Does my stove need to be cured before using it?

Yes, even though we clean it well, there are still residual oils and preservatives on the steel, plus the high temp paint smokes a bit on initial heating.  It is best to fire your stove outside on a low setting for several hours with at least one 3-4′ section of stove pipe “To create a draft.”  The smoke is strong but safe to breathe.  

How long should I leave my draft open when heating my hot room?

The draft should never be left in the high burn position for longer than (5-10) minutes to prevent overheating.  Your hot room should be up to temp in roughly 45 minutes in a well-insulated hot room.  When the draft lever is left in a full-open position, you send all the heat right up the chimney and not heating your hot room.  It will also severely overheat the stove.  To effectively heat your hot room, you want to lower the draft lever between 1/8th and 1/4 open after the logs are burning well.  This will heat the hot room and not send the heat up the chimney.

Is it approved to UL standards?

Yes, it’s approved to UL #1482 by PFS.  Only one on the market that we are aware of at this time.

Is it brick-lined and baffled?

Yes, it is brick-lined to prevent warpage, and coupled with the baffle, enhances the burning of gases.

Is it an air-tight stove?

Yes, the only air it gets is what you set on the carburetor. The doors are sealed for airtightness.

Does my Kuuma stove come with rocks?

No, but we recommend granite or quartz, which are often found locally at lakes and streams.  Many retail landscaping businesses often sell them as well.  We recommend golf ball size with a slight variation.  If you pick your own, please wash with warm water and soap before installation. 

Can you heat water for bathing at the same time it heats the room?

Yes, with the optional 12 or 16-gallon stainless steel hot water tank, water heats very quickly.

Can you see the fire?

Yes, if ordered, an optional 5″ x 8″ glass window is available to watch the burn, provide an additional light source, and make your sauna experience even more romantic and enjoyable.

Is the glass window easy to clean?

Yes, if ever needed it’s easy to clean by dipping a wet rag into ash located in either the firebox or ashpan and wiping followed by drying with a paper towel.  

What size room will it heat?

Based upon how well the heating room is insulated, the small stove is for up to an 8 x 8 x 8 room, the medium is for up to 10 x 10 x 8, and the large is for bigger saunas.

What length of wood works best for each sauna stove?

16″ wood lengths for the small and medium sauna stoves. 20″ wood lengths for the large sauna stove.

Can you load wood from outside of the dressing room?

Yes, the 8″ or 12″ optional extensions are used to go through the wall.  We don’t recommend this because an outside feed adds about $1,000 to building construction costs, and you also lose 25% of the heat from the stove, so you need also to upsize one stove size.  Almost all stove damage we’ve ever seen due to overheating has been because the draft isn’t properly managed because the control isn’t in the hot room.  If you still want an outside feed knowing this, we will be happy to build it for you. 

What are the Clearance Requirements (Meet UL standards for insurance)?

  • Using a heat shield, you need a 7″ clearance from the shield on the stove to a non-combustible shield on the wall with a 1″ air gap behind it.
  • If you have heat shields on your sauna but not on the wall or vice versa, you need an 18″ clearance.
  • If your ceiling is 7’6″ or less, a 3’x5′ heat shield on the ceiling with a 2″ air gap above it is required.
  • Without heat shields or non-combustible surfaces, you need a 36″ clearance.
Another unsolicited review...
When I purchased my Kuuma Wood Sauna Stove from you in the summer of 2008 - I figured i'd give it a few years of use - and Then decide if I wanted to send you a glowing review of it. Well - after my 3rd winter of regular use on it - I can't say enough good things. I absolutely love the stove for a number of reasons.
- It burns incredibly efficiently. Starts with very little smoke and progresses to No smoke and burns very efficiently with excellent heat output.
- The chamber and exhaust design is such that it puts no sparks out the chimney at all. Not sure if this is intentional or a byproduct of the burning efficiency of the design - but the way the stove exhausts above the door - moving the hot air under the rock carriage - and out the flue at the rear - provides not only excellent heating - but in three years I have never been able to see a spark coming out the chimney - and I burn a lot at night.
-The actual design of the doors and hinges makes them very easy to remove for maintenance. I have found it desirable to hit the stove doors with some hi-temp paint every couple of years for aesthetic reasons. I have come to appreciate greatly the many small design decisions you've made to make this very easy.
- I have learned how to manage the temperature of the room and can run it as low or as high as i like now - From the 155 degree high humidity that my wife likes - to the 220+ very dry runs that I enjoy on a cold snowy night. You have built an absolutely incredible stove - and I thank you for it. I'm only in my 40's - but I have a feeling the stove will last through multiple saunas and it will be an heirloom passed down to my kids. Thanks,
