Built-In Spa vs. Hot Tub — Which Makes Sense?

Attached gunite spa

Built into the pool with shared equipment. Spillway feature looks incredible. Cost added to a new pool: $12K–$25K. Best long-term value if you're building a pool anyway.

Standalone acrylic hot tub

Drop-in, plug-and-play (or hardwired). Bullfrog, Caldera, Hot Spring are the brands worth buying. $8K–$18K including delivery and pad. Best if you already have a pool or aren't building one.

Swim spa

12–19 ft current-jet pool/spa combo. For lap swimming year-round + hot tub. $25K–$45K. Great for smaller yards where a real pool doesn't fit.

What to spec

• Spa size: 6–8 person is the entertaining sweet spot.
• Jets: 30+ for real therapy.
• Heater: separate gas heater for fastest heat-up.
• LED color lighting and waterfall spillway add the wow.
