You don't need a bigger pool.
The most common reason a backyard pool goes unused: it's too short for a real swim. Three strokes and you're at the wall, turning around, breaking every rhythm you build. So the pool becomes a place to cool off — not a place to actually swim.
A Tether fixes exactly that. Anchor yourself with a fiberglass pole and a stretch cord and you swim in place — continuous laps, no wall, no flip turn, for as long as you want. The pool you were about to give up on becomes the one you swim in every morning.
No renovation. No contractor. No $15k.
A current machine means plumbing, pumps, an electrician, and $15,000 and up. A Tether is a fiberglass pole that mounts to your deck and a belt on a stretch cord — set up in an afternoon, out in seconds when you want the pool back. Not sure it'll mount to your setup? Send a photo of your deck and we'll confirm the fit before you order.
How it works
Mount the base
The base fixes to your pool deck — concrete, wood, or pavers. Nothing touches the pool itself.
Clip the cord
Drop in the pole and clip the EPDM stretch cord between your belt and the pole.
Swim
The cord flexes with every reach, so your stroke stays natural — lap after lap, no wall, for as long as you want.
The swim you couldn't get before
No wall, ever
The biggest change: you swim continuously. No touch-and-turn every three strokes, no rhythm broken — just stroke after stroke, the way open-water swimming feels.
A natural stroke
The cord gives as you reach instead of jerking you back, so your form stays exactly like it does in a long-course pool.
Resistance you set yourself
Swim easy and it eases with you; push harder for more. Relax your swim, relax your resistance.
Every stroke
Freestyle, backstroke, breaststroke — all of it, in the pool you already own.
Pool Owners
From pool owners like you
If you have a pool that's not big enough to swim laps, you need one of these. A few hundred bucks vs a $15k–$20k add-on propulsion system is a no-brainer. Way, way better than any of the tethers on Amazon. The quality is great.
We built a small pool so we could heat it year-round. Swim Tether allows us to swim in place — easy to install, very easy to use. Even better, my Garmin tracks strokes, distance, strokes per minute — all the same stats I get swimming laps in a longer pool. Super impressed with the ST3.
Amazing set up that allows me to swim in the comfort of my own pool! So glad I discovered this :).
Which pole fits your pool?
Not sure? The kit builder recommends one from your pool's length — and you can send a photo of your deck for a fit check.
Questions pool owners ask
Will it fit my pool?
If you can mount the base to a deck, patio, or pool surround — concrete, wood, or pavers — a Tether works. Pools from about 8 ft on up. Send a photo of your deck and we'll confirm the fit before you order.
Do I have to drill into my pool?
No — nothing touches the pool itself. The base mounts to the deck or surround beside it. Concrete, wood-deck, and paver mounts are all available.
Does it work with an above-ground pool?
Yes, as long as there's a solid surface next to the pool to mount the base to. Send a photo and we'll confirm the fit.
Which pole do I need?
It comes down to your pool's length. The kit builder walks you through it in about two minutes and recommends the right pole for you.
How does it hold up outdoors?
The pole is pultruded, UV-protected fiberglass — built to stand up to sun, chlorine, and salt water year after year.
What if it's not for me?
Every kit is backed by a 1-year warranty and 30-day returns.
