Let customers speak for us
The rugged rock-like exterior blends beautifully into our deck design. The seating for six is spacious, and the 10 therapy jets deliver smooth and relaxing streams. Heats quickly and hides all the mechanicals underneath. Totally exceeded our expectations.
much better than our old open fireplace
We love it! It looks very realistic!
Love the tropical vibes it brings to my backyard. Worth every cent. Fast ship and great service.
Peaceful water sound and super easy to maintain.
Looks great in the living room. It puts out really nice flames.
This massive waterfall made our pool feel like a resort. The roar of that cascade is hypnotizing and the finish looks incredibly lifelike. We chose brown rock and it blends perfectly. Installation needed 3 people, but totally worth it.
Does exactly what it’s supposed to do.
Looks incredible in the backyard. Setup wasn’t hard
We sold our wood unit for this, and haven’t looked back. Easy pilots, no mess, looks great
