Plumbing for outdoor showers is dependent on a variety of factors.
Factors to keep in mind:
• Typically the cost for hot and cold water for the shower with a drain tied into the sewer costs $8K+.
• For more context, running cold water to your shower may not require permits, hot water and sewer connections typically do. The cost of the permit will be dictated by the distance from the point of the connections to the shower itself.
