At Sun Home, our products are built for long-term performance. If something needs attention, we make it simple to get the right replacement part, whether it’s your sauna or your cold plunge.

Understanding Your Coverage

Your eligibility for replacement parts depends on your warranty coverage.

  • Coverage varies by product type and component
  • The first 90 days include parts, shipping, and labor for qualifying issues
