    Someone else posted about the Chofu recently. Looks cool but do you have to drain it all the time in winter to keep it from freezing between use? I would imagine that the heater water jacket could crack if you let it freeze. Perhaps it isn't as practical as it sounds, at least for outdoor use.

    The problem I've always thought about with these is sanitation. Their site actually says the best method is to drain and refill the tub for sanitation and that's a lot of water.

    We looked at the snorkel tubs which are a wood hot tub kit with a submerged wood fired stove to heat it. They suggest draining it every few days for sanitation purposes -- they also do not address what to do to prevent freezing.... I would like to be able to use it on a cold winters night after coming home from work sitting with DW and looking at the stars..... but fresh water every day would be prohibitive.

    I thought the reason for going with a stock tank was because the amount of water was low enough to allow for it to be drained and refilled with each use.

    A standard shower uses up to 50 gallons and these 2 person "stock tank" tubs take less than 150, and we wouldn't use it daily.

    Plus you can save the grey water because it wouldn't have yukky chemicals in it that would hurt the garden...


    Homesteaders work really hard and have few luxuries in life. Hot tub's and sauna's are the 2 things we're not giving up....

    for medicinal purposes, of course...

    Years ago I made one out of a 300 gallon rubbermaid stock tank. I still have the jets and tubing, pump but needs repair(seal), air blower, etc if you are interested Minnikin.

    Shoot a stock tank whirlpool is easy
    put concrete blocks under a good steel tank build a fire to heat the water .
    and clamp a 15 hp johnson to the side .
    fi ya dont like the idea of havin it up on blocks (some folfs are snooty about blocks) weld ya a 30 gallon oil drum in the middle and build your fire in there

    my dad has built several hot tubs over the years. concrete blocks make a good hot tub, back fill all the tubes for strength, 5" concrete floor with the first course of blocks sunk 1/4 of the way into the floor, rebar in all tubes. a whole house water filter from american pluming with a filter that is commonly available with a small 110 or 12vdc pump to circulate the water through the filter. a RV water heater mounted so that it sits midway to the hight of the water and it will work on convection to circulate the water, and you can take off the temp control knob so you can set the temp down to a low setting when not in use.. the pump filter will keep the water moving, and therefore not freeze. a half cup of bleach for a replacement to expensive chlorine tabs.

    the last one he build was buried half way in the ground, and insulated, then sided with exterior plywood. Use 1" Styrofoam panels for the top. thats it.

    total cost: $450 for the last one.. 6' tall 6' wide 4' deep
    P.S. make sure TO USE A GFI OUTLET, AND TEST IT EVERY TIME YOU ARE GOING TO USE THE TUB!!!

    "and the redneck yard of the week is..." lol, just kidding, but i do hear banjos playing all of a sudden. :)

    i like the 15 hp johnson idea. perhaps a broken air compressor hose would work too.

    I have thought about using an old cast iron tub. Make a "cradle" out of cinderblocks to support it on three sides about 2 feet off the ground with a firepit under. Place it ajoining your campfire pit so you could feed hot coals under the tub. I am going to try it this summer, total cost would for the cinderblocks, old tubs are giveaways. What do you think? Boxwood?...Joan

    The best time to use a hot tub is when it's cold out, unfortunately that's also when there's no garden to water. The freezing definetly would be an issue in colder climates too. You would also have to plan in advance when you wanted to soak to allow the water to get up to temp and then have to regulate it pretty accurately. I know in our old hot tub just a few degrees too hot and you went past the point of comfort to feeling like you were being cooked, probably not good for your health.

    Thats the beauty of the outboard no need for an air compressor the exaust is vented into the water creating bubbles it also does the added job of killing bacteria :rolleyes:
    Haven't actually done this myself though I am guilty of putting large blocks of dry ice in our swimming pool in the summer to help cool it off makes for a great big bubbling cauldron with fog rolling off.
    No banjos but we do have a fiddle :)

    I've been eying this one for a couple of years:

    Cowboy Hot Tub

    but I like the looks of that Chofu heater. We have a tank for this express purpose and occasionally heat water in galv. tubs to fill it but it's such a pain that we rarely make use of it. I'm going to get one of these heaters someday.
    I do have an old bathtub on blocks that I use to heat water and dip pigs on butchering day. It heats the water pretty well and, though scrubbed clean, I don't think I'd like to soak in the pig tub - too many memories...
