Who we are

Diamond Water Spa Care is a family-owned business proudly serving Sonoma County since 1999. Our founder, Dan, began his career as a top hot tub sales professional before managing a local store, where he saw the need for specialized, high-quality spa care. Recognizing this gap, he established Diamond Water Spa Care with a sole focus on expert hot tub water maintenance, ensuring clean, balanced water and exceptional customer service.
