Keep Your Tub Happy with Sirona Spa Up
After a long week, your sore muscles deserve a relaxing soak in your home spa. But without proper pH and alkalinity levels, your hot tub can experience corrosion and other issues. Bring your spa back to balance with Sirona Spa Up.
The granular formula raises pH and total alkalinity in your spa water. This keeps levels above 7.2 pH to prevent corrosion. Properly balanced water also allows your sanitizer to work optimally at keeping water fresh and clean.
With Sirona Spa Up, you don't have to worry about equipment damage or compromised sanitation. Regular use ensures safe, soothing soaks every time. The result is clean, clear, healthy spa water for whole-self wellness.
Maintain a tranquil home spa environment with this easy-to-use formula. Experience the full benefits of your hot tub with a little help from Sirona Spa Up.
Available in a 2 lb size - perfect for keeping your spa water balanced. Add Sirona Spa Up to your hot tub routine for clean, conditioned, welcoming water.

FAQ
How long does delivery take?+
2–3 weeks from order. Cold plunges and saunas ship curbside LTL freight direct from the manufacturer; you'll get tracking and a scheduled delivery window 24-48 hours before drop-off. Chillers and small items ship parcel.
Is shipping really free?+
Free curbside freight on cold plunges and saunas to the lower 48. The carrier delivers to your curb or driveway; you handle final placement and quick DIY setup (we text you through it), or we can refer a local installer. Chillers and accessories ship parcel.
What's the warranty?+
It depends on the brand — every product carries the manufacturer's own warranty, which we pass through and help you file. Dundalk cedar cold plunges carry up to a 5-year residential limited warranty on the tub (parts only); the bundled chiller is typically 1 year. Golden Designs and Maxxus saunas run 5 years on heating elements and electronics, 1 year on the wood. Most other brands are 1–2 years. You generally cover shipping to return a defective part. Full terms are on this product's page — text us and we'll pull them up.
What if something breaks?+
Text us a photo. We diagnose it, file the manufacturer warranty claim for you, and expedite the maker's part. Most issues resolved fast.
Can I return it?+
30-day try-it-cold guarantee on uninstalled products. After 30 days, warranty applies.
