SunStrong Extreme: $150 We upgrade every Sundance Spa automatically to a SunStrong cover, and that is included in the price of your hot tub. SunStrong Extreme is an additional upgrade that increases the foam density from 1.5 pounds to 2 pounds and increases the taper from 4'-2.5' to 5'-3'. This adds even more insulation, and allows water to run off easier.

NOTE:Essentials package is not available on Tacoma or Denali (This is because the shape and the spas and cover lifter.
