We Bought a Wood Fired Hot Tub

Let me be clear about this up front: we were not hot tub people. If someone had told us a year or two ago that we’d end up buying a hot tub – much less a wood fired one – well, I can’t speak for Kate, but I would not have believed it. Neither of us grew up with a hot tub, lived somewhere that had them or belonged to social scenes in which hot tubs were a regular method of socializing.

Not that there’s anything wrong with being a hot tub person, obviously. It’s just that that was not a descriptor that would have applied to us. And yet we are now technically hot tub people, of a sort. How did this happen?

Three things conspired to turn us into the proud owners of a Goodland wood fired hot tub.

First, and most importantly, was our move to the island. One of the things that happens when you move to a beautiful place is that you’re not inclined to leave it for anything less than exotic destinations. As we shifted away from spending a summer week at cottages on the coast up north, then, we decided to deploy some of that vacation budget to exaggerating the vacation-like characteristics of our existing house. How could we make it even more enjoyable to spend time here during vacations? As we might put it in tech, how could we give our regular house new features? That led us to begin considering various additions like saunas – something we still might do eventually. We did some research, and that’s when social media kicked in.

Second, then, was YouTube. As we started casting about for ways to upgrade our house, YouTube’s algorithm inevitably led me to this video about a family that purchased a Goodland wood fired hot tub. Not only had I never heard of Goodland, I didn’t know wood fired hot tubs existed. The idea of a wood fired hot tub, which is an experience quite distinct – for better and for worse – from a traditional electrically heated hot tub, however, seemed intriguing. They’re not for everyone, as I’ll come back to later, but we were at least in the target demo as wood is our primary heat source for the house in winter.

Last came the unexpected and improbable discount. Knowing what we know now, which is that the hot tub gets basically daily usage, I wouldn’t have waited on a discount. We’d pay full fare, and happily. Not being hot tub people at the time, however, we were intrigued but on the fence, skeptical as to how much we’d use it. Then, having signed up for Goodland’s newsletter, I got this email.

Over a thousand dollars off because it literally fell off a truck and got scratched, and the tub was already here in the great state of Maine. That seemed an awful lot like fate, so we pulled the trigger. And since it arrived in July, at least one of us has been in the hot tub nearly every day that it hasn’t rained. Also, a couple of days when it did rain.

If you’re at all curious about the Goodland, you probably have questions. I certainly did. To Goodland’s credit, they’ve answered a ton of them here. But here’s what I’ve figured out thus far after six months of usage. If there’s anything I missed, drop a comment or email me and I’ll update this. I’ll also do a follow up post on our water treatment process later; that’s involved enough to need its own space.

Why get a hot tub?

Everyone’s reasons here will differ. For many, as mentioned above, it’s socializing. While you can technically fit four adults in this tub, however, that’s not why we bought ours. What we were looking for was an opportunity to spend time outdoors, in all seasons, in a place that is inherently screen-unfriendly. Whether it’s the whole family, Kate and I, or just one of us individually, hot tub time is a time to sit, soak and take in the blue sky or the night sky. Particularly if you’re in a relationship with someone, a hot tub – at least in our experience – represents an opportunity for more focused, less distracted one on one time. It’s an investment, in that way, in your relationship.

I’ve also found that if I’m quiet enough while I’m out there, it’s like being in a blind for watching nature go by. So far I’ve seen foxes, raccoons, deer and several neighborhood cats saunter by no more than twenty feet away – totally unaware of my presence.

Why get a wood fired hot tub?

Part of it is cost. For a traditional hot tub we’d have to have an electrician in to do potentially expensive work. For us, on the other hand, as a household who already deals with firewood on a daily basis, there is no additional cost to a wood fired hot tub. But there is also an almost meditative benefit to using a wood. It’s inarguably less convenient than a regular hot tub where the temperature is maintained constantly – it can take a couple of hours to get up to temp. But the process of building and starting a fire has value in the same way that heating the house with wood does. For me, at least, the ritual of heating the tub is an enjoyable one, a contemplative one. Your mileage may vary on that, of course.

Why buy a Goodland?

For us, at least, it was a couple of things.

• Aesthetics: the Goodland hot tubs are beautiful to look at. Aesthetics are generally more Kate’s concern than mine, but even I appreciate the way it looks.
• Company: the company, which is very small and Canadian (a plus for Kate as her Mom is Canadian), encourages via their products a slower, more thoughtful approach to life – an approach that resonates in a world that gets more sped up by the day.
• Design: the hot tubs are well and thoughtfully designed, and not only are easy to take apart and set up, but can be moved and installed by two people. They’re also built with materials intended to last.
• Price: at ~$6300, the Goodland is not cheap. But given that quotes for a lot of the traditional hot tubs start at $10,000 – and that’s before the requisite electrical work, installation charges and so on – the Goodland was more affordable for us even absent the discount. And it has no impact on our monthly electrical bill either, unlike the traditional alternatives.
• Size: not being hot tub people, as mentioned above, we did not want a huge tub that would seat half a dozen or more people. We also don’t really have the space for that. The Goodland’s size fit our needs best.

Is it worth the money?

Everyone’s answer to that will be different. For us, it was about usage. If we spent that much money and we used it every so often, as a special occasion, that would be a waste of money. If we used it multiple times per week, on the other hand, that would be worth the money.

For us it’s easily been worth the money. Honestly the first time I used it in the dark and the cold – and more recently, the snow – and looked up at the stars while floating in 100 degree water, it was worth it.

If I buy a Goodland, do I need the cover and end covers?

If you’re going to reuse the water at all, you definitely need the covers. Even with them it’s amazing how much crap ends up in the tub. If you’re not going to reuse the water, you probably want them anyway to keep leaves and other debris out of the tub when it’s empty.

They’re an added expense, yes, but it beats having everything the wind blows ending up in your tub.

Speaking of reusing the water, is the hot tub’s water treated with chemicals?

The short answer is that you can do either untreated or treated water. And as the tub is cedar and aluminum, you can also do salt water which is what we do.

Which should I do?

That depends entirely on your situation. In the video I linked to above, they pump water into their tub from a nearby lake when they need it, and drain it when they’re done. So they don’t treat their water. If you have a nearby water source, be that fresh or salt water then, you can just use that. This is much simpler and lower cost.

We don’t live on a lake, and we’re on a well. Our well is good and deep, and the tub’s capacity is comparatively small at ~250 gallons, but we don’t want to run the risk of overtaxing the well at our primary residence so we treat our water.

I’ll save the process for another post, because while it’s simple enough once you figure it out there are a lot of moving pieces. Detailing all of that would take more space than I have here.

How long does it take to heat the tub?

It all depends on your starting temperature. When I’ve got residual heat left over from the day before, and it’s a temperature in the sixties or seventies, it’s maybe an hour and a half. If temps are in the thirties or forties, however, it’ll take several hours. Instead of starting a fire in the afternoon, then, I just do it in the morning.

I’m concerned about the water freezing in the winter: how long does it take for the water to cool down?

Longer than you’d think. If you’re heating the water every day or every other day, it’s not an issue unless you’re dealing with extreme cold. In our case – with only an extra layer of rigid foam insulation sitting under the tub – here’s an example. Firing up the tub one afternoon, the temperature peaked at 103.6F at 2:30 in the afternoon. The low temperature that night was 17F. By 8:30 AM the next day the temperature was down to 65.3F. And that’s a more extreme example; typically if the overnight temps are in the twenties and thirties you might see the hot tub temp the next day in the seventies.

The takeaways, then, are that extreme cold can bleed heat reasonably efficiently, but even in very cold weather a heated tub is not going to freeze overnight. And you can slow that further by deploying insulation on top of the water and/or a tank de-icer (though as I discovered, you can’t use that with salt-water because the stand is not stainless).

What are comfortable temperatures?

Everybody’s tolerances differ, obviously, but speaking personally the sweet spot is 98-101F. 102F is hot, and 103F is too hot for me for more than a few minutes.

To maximize time in the water, however, I’ll get in at any temp north of 90F and comfortably wait for it to warm up.

How do I manage temperature?

There’s a bit of a learning curve here, but it’s not too bad. Generally, you use a Goodland like you would a wood stove. I generally line the bottom of the stove with small logs, light a firestarter like fatwood on top of those and then place kindling strategically around that.

That will typically burn for an hour or two, then I just feed it until I get close to my target temperature and back off. When I want combustion to stop or slow, you can either close the opening entirely or leave a slim crack at the back open.

How do I get the temperatures even at the top and bottom of the tub?

Left to its own devices, any body of water will stratify into layers of differing temperatures. To ensure that you’re not stepping through a top layer of hot water into much cooler water, the contents have to be mixed. In an electrical hot tub, this work is performed by jets. In a Goodland, you have two options.

First, you mix it by hand. Goodland includes with the tub a nicely designed paddle which will ensure the water mixes top to bottom.

In our case, however, because we’re treating our water, we have a filter that sits in the tub and circulates the water as part of its normal operation.

Surprisingly, however, because most traditional hot tubs come with their own filtration system, it was difficult to find one appropriate for a wood fired hot tub like the Goodland. I eventually settled on this one designed for above ground pools. It’s a little too big and attachment is wonky, but it works and keeps the water clear.

What other accessories do I need to budget for?

Aside from the chemicals if you’re going to treat the tub, and filter system mentioned above, there are a couple of things that we use. Some of which are necessary whether you treat your water or not; others of which are optional.

• Hose Filter: our well water is full of iron, so this screws on to our garden hose and pre-filters the water before it hits the hot tub.
• Water Temperature Sensor: we have an Ambient weather station in our house, and this floating wifi temperature sensor pipes our current temperature into our display at home. As a bonus, you can also check the tub temperature via the Ambient app, and via their API you can pull a JSON feed which I use to display the hot tub temperature on our family dashboard.
• Smart Power Cable: in order to be able to remotely turn on and off our hot tub filtration system and our salt water system, I picked up this smart outdoor power plug. I can schedule them and turn them on and off as necessary from my phone.

Do you happen to know how much a fully loaded hot tub weighs?

The tub weighs approximately 275 pounds with all of its parts, and the 257 gallons of water weighs approximately 2143 pounds, so before any people are in the tub you’re looking at a weight of around ~2450 pounds.

Can my deck support that much weight?

I was curious about the answer to this myself, because a lot of the Goodland videos you see have the tubs deployed on decks of varying heights and design. Because my wife is a lawyer, however, I’ll note that none of the below constitutes advice and I have no idea what your particular deck may hold. But I can at least tell you how I looked at the question.

The first thing I did personally was inquire with an engineering company as to what it would cost to get a professional assessment. Their quote was $2K, which meant that I could spend a third of the cost of the hot tub only to be told that my deck could not support the weight. I opted out of that.

Google research, meanwhile, told me that a deck approximately our height off the ground could support up to 100 pounds per square foot. My conservative math said that the Goodland would represent between 125 and 150 pounds per square foot, so our original plan was to drop in four new posts to over-reinforce the existing area of the deck.

Given that this would have mean trying to dig four foot deep holes under the crawlspace of our deck, however, we decided to punt on the matter and simply set up the tub on the ground. That was a good decision, because I no longer have to worry about load capacities and so on but more because I didn’t have to roll around under the crawlspace under our deck for a week.

What should I know about a wood fired hot tub that isn’t obvious?

The amount of work that goes into it, especially if you treat your water. It’s worth it for us, but if you’re the kind of person that just wants to get in and get out with no work on your part, this tub isn’t for you.

Anything else to add?

Just that we’re very happy with our Goodland and highly recommend it for those willing to put in a little work. For those with Goodlands already, meanwhile, I’ll follow up later with a post on our water treatment plan if there’s interest.
