Depending on the spa or swim spa will depend on what your pad needs to be made of. Most spas and swim spas are placed on a flat concrete pad.
For most hot tubs, a 4 inch reinforced concrete pad is usually the most recommended substrate. Many hot tubs can be placed on decks or other flat solid surfaces. Make sure to check the requirements for your hot tub model in the pre-delivery instructions for your hot tub.
For most swim spas, a 6 inch reinforced concrete pad is recommended. Check the requirements for your swim spa model in the pre-delivery instructions.
If you need further assistance, please call your sales representative.
For best results with your electrical connection:
IMPORTANT: The neutral wire from the spa goes to a specific location on one of the breakers in the spa sub-panel! NOT to the neutral bar.
If your electrician has further questions, please refer them to the instructions for your spa model in the pre-delivery instructions found at this link.
If you need further assistance, please call your sales representative.
