Why ONSONSPA
Q&A
Frequently Asked Questions
Where can I install my hot tub / swim spa / cold plunge?
Place it on a level, load-bearing surface such as a concrete pad or reinforced deck — never directly on grass or sand. Confirm your site's weight capacity before delivery.
What power supply does it need?
Most hot tubs and swim spas require a dedicated 220V circuit; some smaller plug-and-play models run on standard 110V. Check the power spec for your specific model before ordering.
Can I use it outdoors in winter?
Yes — well-insulated units are built for year-round outdoor use. Keep the cover on when not in use to retain heat and reduce running costs.
How do I keep the water clean?
Follow the included maintenance routine: sanitize regularly, keep pH balanced, and clean/replace filters on schedule. Full water-care guidance ships with the unit.
How many people does the model I'm looking at seat?
Capacity is listed per model on the product page — units in this range seat from 2-4 up to 5-7+ people depending on the model you choose.
Delivery, warranty and returns for large units?
24-month warranty included. U.S. delivery: oversized freight is priced at checkout based on your location. 30-day returns apply, with return shipping possible on oversized items.
