PRODUCT OVERVIEW

Prolong the life of your hot tub with the Lay-Z-Spa Floor Protector. Made of a durable polyethylene material, the floor protector provides an additional layer of protection and insulation between your spa and the ground. The floor protector also improves the energy-efficiency of your spa by retaining heat and preventing it from escaping through the bottom liner.

The 16 connectable pieces easily link together to create a customizable size for your specific hot tub, and the set also includes an additional piece to protect the bottom of the pump. The Lay-Z-Spa Floor Protector is compatible with all types of spas; multiple sets can be connected together for spas larger than 1.96 m x 1.96 m (77 in. x 77 in.).

Once it is set up, add the finishing pieces to create straight edges and a luxurious look. Give your spa a long life, protect it from damage and improve its heat retention with the Lay-Z-Spa Floor Protector! This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 3110-00-144-8925, indicating validated use in U.S. government and defense logistics supply chains.
