77" x 28" Coleman SaluSpa 4-Person Inflatable Spa Hot Tub (Forest Green) Expired

Snagged one from Amazon. Keep in mind that these are basically "disposable". There's a reason why the warranty on the liner is only 6 months. I got the smaller costco version when it was on sale for $300 and it sprung multiple leaks within 2-3 months. But for the price and the convenience of not having to run wiring and plumbing? Good enough. This one is the second biggest round inflatable they sell, I believe. They mostly all use the same pump, it's just a different liner.

Things to keep in mind with these hot tubs:
1. They're disposable. If you get a full year out of them, consider yourself lucky. Two years is the maximum I've seen them last. The one I got developed small holes in the seams, and the inside of it would fill up with water. It was usable for a little bit still when it started leaking, but soon it got bad enough that it was dumping gallons/hr onto the ground through the pipe where the air pump connects.
2. The pump/heater/filter is weak. The heater is limited to 104F. If you take the top off, it will cool off to 102-ish in 10-20 minutes but is able to keep it in the 100-102 range. If you turn the bubbles on it gets cold pretty quick. The same applies for the initial fill: expect to leave it running overnight to get it up to temp.
3. The filters suck. Don't bother with washing them out too much, just get a cheap 6 pack of them on amazon. They last 1-3 weeks even with daily rinsing and then you'll start getting flow errors.
4. You have to stay on top of water chemistry. They will get skunky real quick.

Model wise it goes like this:

1. Grenada: 93x28 357gal - I don't think the heater/pump would be able to keep up with this size. Never seen one on sale or in store.

2. San Francisco: 90x28 square 312gal. Same pump unit. Absurdly overpriced.

3. Milan: 77x28, 242gal. Wifi. The Coleman model is identical as far as I can tell aside from not having wifi.

4. Budapest: 77x26, 240gal. Wifi

5. Helsinki: 71x26, but has a different, thinner wall design that gives it a 297gal capacity

6. Hawaii: 71x26 square, 222gal

7. Barbados, Fiji, Tahiti, Coleman Bahamas: All identical 71x26 177gal models as far as I can tell. The only difference seems to be that the Barbados comes with am external liner, and the Tahiti has an extra $2 of LEDs. Probably not worth bothering with the external liner. The seams on the internal liner will give well before any potential benefit could be observed, and it tends to trap moisture that will allow mold growth. The Costco Laguna Model also slots into here. I think it's the equivalent of the Barbados model since it comes with the external liner. They claim 2-4 people, which is about right. You can fit 2 people in just fine. Three means you don't have room to stretch your legs. I don't think you could really fit 4 people in it comfortably unless they were 5 foot tall or something.

The Miami is currently on sale on amazon for $269, but you might as well pay the extra $14 and get almost double the water capacity. The Tahiti is also on sale for $304, but if that's the one you get, a slickdeals-er you are not.

8. St. Lucia: 67x26, 160gal

9. Vancouver: 61x24, but with a similar thin wall design to the Helsinki that gives it a 213gal capacity. Wifi.

Parts are available. Pricing is all over the place though. The bestway site appears to be selling two Milan liners right now that are identical from what I can tell. One is $170 one is $200. The identical coleman liner is $220. They have two Tahiti liners. One is $150 one is $200. What's the difference? Who knows? Why bother when you can just toss the whole thing and get a new for almost the same money. The only reason I can see getting one would be worth it would be if you had a 160-180gal model with a bad liner and you picked up a Milan liner for $170 to get the 242gal capacity, but their shipping is $75. Why pay $250 for a liner when you can just buy a new one for $280?

All in all, if you keep in mind that these are disposable, they're a good buy at the $300 price point. If you can find an extended warranty or something on them it's definitely worth buying, as odds are you'll end up replacing the liner within a year at the very minimum, and the pump likely won't last longer than 2-3.

I have the Bestway version. Same size. Just use bromine tabs for water and toss a little powder shock treatment in after each use.
Your power bill will go up depending on how hot you keep it.
Set it on 1" thick hard foam pads to insulate from concrete that tend to pull heat out of it.
I got a large round outdoor table cover from AMZ to go over mine to keep the outside cleaner and the sun's uv rays from pounding it in a daily basis.
You can use a strong stream of water from a hose to clean the filters, an occasionally give them a soak/rinse in bleach, but I'd still replace them every so often.
Mine has two filters but the secondary "side" water return barely pulls any water, so I wound up putting that filter on the main return and the second filter where the water comes into the tub. Basically filtering before and after the pump, if that makes sense. Doesn't seem to affect water flow.

U leave it inflated, filled and covered when not in use.
