Moderate. Feasible for highly experienced DIYers with a strong understanding of plumbing, electrical (if applicable), and carpentry codes. However, engaging licensed professionals is highly recommended to ensure full code compliance, prevent costly errors, and ensure safety, especially with complex drainage or electrical connections.
Installation requires coordination of multiple trade disciplines (plumbing, potentially electrical, and structural), adherence to frost depth requirements, appropriate drainage solutions, and specific material selections suitable for DuPage County's climate and code compliance.
