The part nobody told you
If your swim spa hasn't felt like real swimming yet, you're not alone — and you didn't mess up. Jets make a current for you to push against; they were never built to feel like gliding through calm, open water. That feeling just doesn't come in the box, and nobody told you it was the missing piece.
Here's the good part: the fix is small. A Tether lets the water stay still while the cord gives with every stroke instead of fighting it — no tension, nothing pulling you back. Just you, swimming the way you would in open water. One stroke after another, for as long as you want.
You may already own half of it
Most swim spas leave the factory with a tether base built into the rim — that little fitting you may have wondered about. If yours has one, all that's left is the Tether that drops into it. Not sure? Send a photo of your spa's edge and we'll tell you exactly what fits — before you order.
How it works
Drop in the pole
It seats into the base on your spa in seconds — no tools, nothing to drill.
Clip the cord
The EPDM stretch cord clips between your belt and the pole.
Swim
The cord flexes with every reach, so your stroke stays natural — one after another, for as long as you want.
Calm water changes everything
Still and quiet
No turbulence to fight, no bubbles, no motor noise — just the sound of your own strokes.
A natural stroke
The cord gives as you reach instead of jerking you back, so your form stays exactly like it does in open water.
Resistance you set yourself
Swim easy and it eases with you; push harder for more. Relax your swim, relax your resistance.
Every stroke, not just freestyle
Still water means backstroke and breaststroke work as naturally as freestyle.
Swim Spa Owners
From swim spa owners like you
Oh WOW! What a game changer! I thought I had made a mistake getting a swimspa until I got this little gem. It feels very natural like I'm swimming by myself, I don't feel any tension or feel like I'm being held back, just 1 stroke after another after another.
Works really well in SwimSpa — comfortable and can swim as easy or as fast as would like. It also supports the core so good for technique.

Questions swim spa owners ask
Will it fit my swim spa?
Most swim spas leave the factory with a compatible tether base built into the rim. If yours doesn't, a concrete or threaded-wood base mounts to your deck or surround. Send us a photo of your spa's edge and we'll confirm the exact fit before you order.
Do I have to drill anything?
If your spa has a factory tether base, no — the pole drops straight in. Arctic Spa owners: the Arctic Spa adapter threads into the factory receiver, so there's no drilling either.
What if my spa didn't come with a base?
We'll match you to a base that mounts to your deck or surround. Photo verification is on us — send a picture of your spa's edge and we'll tell you exactly what fits.
Which pole do I need?
It comes down to your spa'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 in chlorine or salt water?
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.
