SUB-STRUCTURE

A spa sub-structure provides essential support to the spa shell, working alongside cladding materials to ensure stability and durability. The frame is the backbone of the entire spa, making it critical for the sub-structure to be strong, stable, and weather-resistant.

Steel Spa Sub-Structure

• Steel has the highest strength-to-weight ratio of any building material.

• Corrosion-resistant alloy steel is immune to rot, cracking, splitting, and insect damage.

Wood Spa Sub-Structure

• Wood is the most widely used material for spa sub-structures.

• High-quality cedar and preservative-treated wood offer superior resistance to rot, cracking, splitting, and insects.
