Locally owned
Hi, we're Jeff & Amanda
We started 406 Aquatic Services to bring honest hot tub sales and service to Southeast Montana. We live here too, so we know what a hot tub is worth after a long, cold day, and we know how to keep one running through a real Montana winter.
No pushy showroom. Just straight answers, fair prices, and service you can count on. Give us a call and we'll take care of you.
Financing available
Financing that fits your budget
We offer financing through Valley Credit Union so you can get into the hot tub or swim spa you want without paying all at once.
