Around eight years ago, I built my own DIY hot tub. You’ve probably seen it in the background of half my videos.
Fast forward to today and I’ve helped over 1,500 people build their own, and thousands more with spare parts for fixing their existing tubs. So I like to think I know a thing or two about what works — and what doesn’t.
With that in mind, I thought it’d be worth putting together an honest post about what I’d actually do differently if I started from scratch. Because believe me, I made plenty of mistakes first time round.
Right, I’ve got a brand new project to introduce to the channel today – and this one’s got a really interesting backstory that I think a lot of you are going to relate to.
Meet Jeff from New York, USA. Jeff’s been running an old cedar hot tub for somewhere around 10 to 15 years now, and as much as it’s served him well, the wood has finally had enough. It’s leaking, it’s tired, and it’s time to go.
But here’s the thing – the reason Jeff went with a cedar kit tub in the first place is exactly the same reason I ended up going down the DIY route myself. No access. He simply couldn’t get a plastic shell hot tub into the space. So back in the day, a handyman assembled it on site from a kit, and that’s what’s been sitting there ever since. Sound familiar to anyone?
If you’ve got a Balboa-controlled hot tub and you’re not sure what all those heating modes do, you’re not alone. I get asked about this constantly — and it genuinely matters. Get it wrong and you’re either burning electricity you don’t need to, or you’re jumping in expecting 38°C and getting a lukewarm surprise.
Let me break it all down.
If you’ve got an air button that’s stopped working, or a latching relay that’s given up the ghost, the good news is that this is a really straightforward job to do yourself. In this article — and the accompanying video — I’m going to walk you through exactly what these components are, how they work, and how to swap them out.
Let’s get into it.
With so many air source heat pumps on the market right now, choosing the right one can feel overwhelming. There are dozens of brands, hundreds of models, and enough jargon in the spec sheets to make your head spin.
But here’s the good news — once you know what to look for, it’s really not that complicated. In this article, I’m going to walk you through the key things you need to consider before you part with your cash. By the end, you’ll know exactly what questions to ask and what to look out for.
Let’s get into it.
Right, this is one of those questions that lands in my inbox on an almost daily basis. Hot tub or plunge pool – which one should you build? And the honest answer is that there is no definitive right or wrong. It really does come down to personal preference and your own circumstances. But in this post I’m going to break down the key differences between the two so that by the end of it, you’ll have a much clearer idea of which direction is right for you.
We’re back with another update from Patrick in Wisconsin, and this one is a big one. If you’ve been following Patrick’s basement hot tub and cold plunge build, you’ll know he’s been at this for a while now – and things are really starting to look the part. In this latest update we’re looking at waterproofing, tiling, faux rock walls, and a rather exciting water feature that Patrick and his wife have been working on. Let’s get into it!

Sure, he’d built plenty of things. Deck? Check. Workshop? Done. Custom furniture? No problem. But a hot tub? That was different. That was one of those projects where most people just throw up their hands and call a contractor.
