Eternitree™ Forever Frame

Treated with twice the Chromated Copper Arsenate found in a typical pressure treated board, Eternitree™ is engineered for marine applications where lumber is exposed to extreme moisture for prolonged periods. And unlike almost every other spa manufacturer who uses typical pressure treated lumber and only on the base of the spa, we use Eternitree™ lumber throughout the entire frame, from the bottom to the top, so we can guarantee the frame on your spa to be erosion, rot, decay, terminate & bug free for the life of your spa!
