Hot Tub Base Pad and Leveling Guide

Choose the right base type

• Use manufacturer-approved load-support surfaces. Approved base types reduce settling and shell stress over time.
• Avoid soft, shifting, or uneven ground. Unstable soil can create long-term leveling and plumbing problems.
• Plan drainage so runoff moves away from the base. Dry foundations are safer and help maintain structural stability.

Verify level before delivery

• Check level in multiple directions. Multi-point checks confirm even support across the full spa footprint.
• Confirm final settled height and nearby clearances. Height and clearance checks protect access and cover-lifter function.
• Recheck after heavy rain or soil disturbance. Ground movement can change level and should be corrected before delivery.
