We performed a detailed assessment and measurement of a residential hot tub in La Mesa. Our team carefully inspected the existing unit, which was situated on a wooden deck under a backyard pergola, to prepare for a custom cover replacement. We focused on capturing exact dimensions of the spa shell and the old cover to ensure a seamless fit. Using precision tools, we recorded side lengths and determined specific corner radii using a framing square. We also analyzed the textured grey shell material and the current folding cover's condition to verify all necessary specifications. These detailed measurements allow for a secure, energy-efficient replacement that properly protects the unit from the elements.
