Frequently Asked Questions



What is included with a wood fired Firetub?

  • Tub, stove, stove lid, lower chimney, (with heat shield), upper chimney (with spark arrestor), insulating/protective base pad, floating insulating top, safety fence, shelf, beverage bucket, thermometer, debris net, fill/drain valve, and paddle.

How much does it weigh?

  • The entire weight of the (empty/dry) tub assembly including all accessories is just 125 lbs. Filled with water, the tub weighs over 1400 lbs. 

What are the dimensions of the product?


  • The tub is 6' long, 2' wide and 2' tall. Attached, the chimney reaches to 98 " (or 8'2"). With the chimney and stove removed (in transport condition) the assembly will fit inside the tub.

How much water does the tub hold?

  • Each tub holds approximately 169 U.S. gallons.

How much wood does it take to heat the water?

  • This will be dependent on multiple factors: the temperature of the water source, how hot you want the water, what kind of wood you are burning, how dry the wood is etc.. Generally, you can achieve a comfortable temperature in 2-3 hours. You will be surprised how little wood is required.

How large a piece of wood can I fit in the stove?

  • So long as the wood you are using fits safely inside the bottom of the stove, you can use it. Larger pieces of wood work well once the fire and coals are established. The stove easily accommodates a 2" x 4"  that is cut to 18" in length. 

How do I clean and maintain my hot tub?

  • A Firetub is not intended to be left full of water when not in use. Fresh water is recommended. Change the water frequently and there is no need to use chemicals. Simply fill the tub with fresh water, heat and enjoy a few times; then empty the tub. Use the water wisely as being untreated, it can be re-used as grey water (i.e. for lawns and gardens)

  • It is the owner's responsibility to ensure the hot tub is clean. Always keep surfaces and decks clean. Bacteria and dirt on surfaces may enter into the water with you. Always shower or bathe with soap before use. This helps keep the water free of germs and body oils.

  • Cleaning recommendations:

  • Drain water, rinse tub off with water, (use a garden hose).

  • With a mild soap solution and a clean soft brush, use firm circular motions to clean the tub. Do not use a hard-abrasive brush.

  • Rinse thoroughly with fresh water to get rid of any soap and dry with a soft cloth.

  • Depending on the frequency of use it may not be necessary to clean with soap after every use. Simply rinse with clean water and wipe down with a soft cloth.

How do I remove ash from the stove?

  • Always be sure there is no longer any residual heat prior to cleaning the stove. 

  • How often you clean out the ash depends on what wood you use and how much you use your hot tub.

  • As ash accumulates it will need to be emptied from the stove. When the tub is empty of water, and the stove has cooled, remove the chimney sections and disconnect the stove mount latch pins. Set the stove lid aside and remove the stove from the tub. The stove can simply be inverted to dump the ashes. Any remaining ash can be brushed out. Due to the efficient nature of the stove, and the temperature reached, ash burns to a fine powder so, accumulation is surprisingly little. 

  • Alternatively, a scoop can be used to remove the ash. 

 Does a Firetub require any maintenance?

  • The chimney and spark arrestor require occasional cleaning. This can be done with a brush, air hose, or water hose.

How do I disassemble and store my Firetub?

  • With the stove cooled and water emptied, disengage the stove mount latch pins. The stove and fence assembly can then be laid inside the tub along with all the other pieces. Turn the tub upside down and place it on blocks for long term storage.

Does Firetubs have a warranty?

  • Complete satisfaction is our goal. Our stoves and tubs have a 1-year guarantee on materials and workmanship.
