What Makes the Freeflow Collection Different?
The easiest way into a Hot Spring spa: plug it in, fill it, and soak the same day. No electrician, no subpanel, no permit wait for most yards.
Simply plug it in
Every Freeflow model runs on a standard 115V household outlet, so most installs need no electrician and no subpanel. Many models convert to 230V later for faster heat recovery between soaks.
Move it when life changes
A rotomolded unibody shell keeps these spas light and durable, and the plug-in cord makes them the practical choice for a rental, a first home, or a patio you may not keep forever.
FROG® water care ready
Every model is FROG® Sanitizing System ready: a simple cartridge routine that keeps water clean with less hands-on chemistry. Water care, made simple covers the routine.

Can You Plug a Hot Tub Into a Regular Outlet?
Yes. Plug-and-play spas run on a standard household outlet: fill it, plug it in, and soak the same day, no electrician needed. That’s the Freeflow® collection from Hot Spring and the Fantasy® series from Caldera, and it’s the easiest way to get into a quality spa.
The trade-off is that the jets and heater share the circuit, so on a cold night with the jets wide open the water can cool a touch. Full-size spas run on a dedicated 240V circuit and hold full heat with everything running. In the Northwest you’ll soak year-round, so if long winter soaks with strong jets are the goal, a 240V model is worth the electrical work.

Frequently Asked Questions
Quick answers to the hot tub questions we hear most. The Learning Center covers each one in depth.
How much does a Freeflow hot tub cost?

Can I plug a Freeflow into a regular outlet?
Yes. Every Freeflow model runs on a standard 115V household outlet, so most installs need no electrician and no subpanel. Many models convert to 230V later for faster heat recovery. Our 110V vs. 240V guide walks the trade-offs.
Will it cost a fortune to heat in winter?
A rotomolded shell and a tight-sealing cover hold heat well for a plug-in spa. On a 115V circuit the jets and heater share power, so on a cold night with the jets wide open the water can cool a touch; converting to 230V removes that. The cover is the biggest daily factor.
What size Freeflow do I need?
The collection runs from the two-seat Mini™ up to the five-seat Monterey™ and Aptos™. 2 to 3 seats fits couples and small spaces, and 4 to 5 fits most families. If you’re between two sizes, go by a normal week of use rather than your biggest gathering.
