Swim jets for the pool you already have: retrofit units compared
Plain notes for anyone fitting a retrofit swim jet to a pool they already own. Each page answers one question: will this jet fit your pool, what does it need, and what will it really cost.
A swim jet pushes a current of water at you so you can swim in place in a pool that's too short for laps. A swim jet for an existing pool either clamps onto the edge or gets drilled into it; neither needs the shell rebuilt. The jets are expensive, and the makers' pages are written to sell them. This site lines the models up, checks the numbers against other sources, and says so when the numbers don't agree.
Guides by question: fit, install needs, pool type and cost
- Which swim jet fits your pool?Every model by flow and price, matched to pool length.
- What does each one need to install?Edge measurements, power and drilling, model by model.
- Will one work on an above-ground pool?Rail, depth and length checks, and which pools to rule out.
- What about an in-ground pool?Clamp-on or drilled in, and what your edge allows.
- Retrofit or built-in: what does it cost?Three ways to do it with prices from two makers.
How the claims on these pages get checked
- Each page holds the makers' flow and size claims up against pool length, water depth and simple pump and cost arithmetic, with every source linked and dated.
- iGarden's X and P Series are covered model by model. BADU (Speck Pumps) and Endless Pools retrofit units are on the pool size page wherever their makers publish the numbers.
- None of these jets has been tested for this site. Everything here comes from the makers' pages, plus the few outside reviews that exist.
- Most of the "second sources" turn out to repeat the maker's spec sheet. Where nothing independent turned up, the page says so.
- Store buttons go only to iGarden, as plain links. BADU and Endless Pools don't sell these units online, so they get spec rows and links to their own pages. No one pays this site. How this site works.
- Prices were read in early November 2026 and change often. Always check the store.
Short answers before you measure
- Can you add a swim jet to an existing pool?
- Yes, in two ways. A clamp-on unit hangs on the edge and runs on a battery, and a drilled-in retrofit bolts to the edge and runs on house power. Built-in jets are plumbed into the shell, so they belong with a new build or a big remodel.
- How long does a pool need to be for a retrofit swim jet?
- About 13 feet of straight swim path at the least, by iGarden's numbers, with about 3.5 feet of water. BADU asks for a clear area 8 feet wide, 15 feet long and 3 feet deep for its systems.
- What does a retrofit swim jet cost?
- iGarden's clamp-on X Series ran $1,499 to $3,599 and its drilled-in P Series about $2,000 to $3,999 on Nov 4, 2026, before any install work. BADU puts adding its Inspiration to an existing pool at $3,500 to $4,000, depending on installation.
