5 Mistakes I Made Buying Outdoor Spa Equipment (And How to Avoid Them)

Who This Checklist Is For

If you're shopping for outdoor leisure spa equipment — a hot tub, swim spa, or just a simple jetted tub for your garden — and you're feeling overwhelmed by specs, prices, and brand promises, this is for you.

I'm not a spa manufacturer (I work with Napoleon on gas grills, fireplaces, and HVAC — completely different category). But back in 2021, I was tasked with sourcing a swim spa for a client’s backyard project. What followed was a series of costly mistakes that taught me more about the spa industry than I ever wanted to know. (Total wasted budget: roughly $3,200, including a 1-week project delay and a lot of embarrassment.)

So here’s my 5-step checklist — basically the things I wish someone had told me before I placed that first order.

Step 1: Don’t Trust the “All-Inclusive” Price Tag

Mistake I made: I saw a price for a swim spa listed at $8,900 and thought “great deal.” Turned out that covered the shell and pump only. Delivery, electrical hookup, steps, cover, and chemical starter kit were all extra. The final bill? Over $11,400.

So when you see a price online, ask: “What’s actually included?” Seriously — write down every line item. Most buyers focus on the base unit price and completely miss setup fees, site prep, and shipping that can add 30–50% to the total. That’s the classic outsider blindspot.

Here’s a quick checklist for the quote:

• Delivery (curbside or to the backyard?)
• Electrical work (GFCI breaker, wiring, conduit)
• Base/ pad (concrete or gravel)
• Crane or lift if needed
• Cover + steps + cover lifter
• Starter chemicals

Step 2: Verify the Water Capacity & Filtration Specs (Not Just Size)

The second time I messed up (literally the next order — I didn’t learn fast enough) was ignoring the water turnover rate. The spa I picked looked spacious on paper: 7 seats, 3 pumps. But the filtration system was undersized. Within 3 months, the water turned cloudy despite regular chemical treatment. Cost me $450 in replacement filters and a weekend of draining/refilling.

So ask the manufacturer (or dealer) for the gallons per minute (GPM) and turnover rate (how many times per day the water passes through the filter). A good rule of thumb: 2–3 complete turnovers per day for a residential spa.

Also — and this is something most people overlook — check whether the filter is a standard size that you can buy at a hardware store, or a proprietary one you can only get from the manufacturer. Proprietary filters can be a pain (and expensive) when you need a replacement fast. Learned that the hard way in July 2022.

Step 3: Test the Jet Layout Before You Buy (Seriously)

You can’t tell how comfortable a spa is from a spec sheet. I ordered a “jacuzzi near me” — actually a local brand — based on a brochure. When it arrived, the jets were all aimed at my lower back, and there was almost nothing for the neck or shoulders. My client (who loves massages) was not happy. That mistake cost me $890 in redo plus a 1-week delay to swap the unit.

The fix? Visit a showroom and sit in the exact model you’re considering. Spend at least 10 minutes in each seat position with the jets on. Bring a friend or colleague to be the second opinion.

If you can’t visit, at least ask for a video of the jets running with a person sitting in it (not just a dry demonstration). And ask: can you adjust the flow direction on each jet? Some cheap models have fixed jets — avoid those.

Step 4: Check the Warranty Exclusions (Not Just Duration)

“10-year warranty” sounds great until you read the fine print. I once compared two similar swim spa manufacturers. One had a 10-year warranty on the “shell and structure” but excluded cracking from improper water chemistry (which is basically the #1 cause of cracks). The other had only 5 years but covered everything except misuse.

Guess which one I ended up recommending? (The 5-year one, because it actually protects you.)

So when you see warranty length, also get the written exclusion list. Common exclusions:

• Cracking due to freeze-thaw cycles
• Damage from improper chemical balance
• Discoloration from UV exposure
• Electrical components (often only 1–2 years)

If a manufacturer won’t share the full warranty document before you buy, that’s a red flag. I learned this the hard way after the third rejection in Q1 2024, when I created a pre-check list for our team.

Step 5: Ask About Service & Parts Availability (Local vs. National)

Here’s one most people skip: where will you get it serviced? I ordered a hot tub from an online-only seller (huge mistake). The pump died after 14 months. The seller offered to ship a replacement, but then I had to find a local tech to install it. It took 3 weeks to find someone who worked on that brand. Meanwhile, my client was pretty upset.

Check if there’s a local dealer within a reasonable distance. If not, find out what brands your local spa service technicians will touch. They often have a list of brands they refuse to work on because parts are hard to get.

Also: ask the manufacturer about lead time for replacement parts (pumps, heaters, jets). If they say “2–4 weeks,” that could mean your spa is down for a month during peak season. Not ideal.

Common Mistakes & Final Reminders

Here are a few more things that tripped me up — hope they help you avoid the same:

• Don’t assume a “swim spa” is the same as a hot tub in terms of energy efficiency. Swim spas have larger pumps and often use more electricity. Ask for the monthly operating cost estimate (most manufacturers can give you one based on your local utility rates).
• Get a separate electrical quote early. A standard 120V plug-in spa is easy, but many larger spas (especially swim spas) require 240V or 50-amp circuits. Know that cost upfront.
• If you’re buying for a commercial site (hotel, rental property), the requirements are different — heavier duty motors, more stringent safety codes. Don’t let a residential dealer upsell you a commercial unit without proper documentation.

The vendor who said “this isn’t our strength — here’s who does it better” earned my trust for everything else. Honestly, I’d rather work with a specialist who knows their limits than a generalist who overpromises.

Good luck with your spa purchase. Hopefully this checklist saves you the $3,200 and the embarrassment I went through.
