The answer to 'how long does shower last' is that the typical lifespan of a shower is 5-15 years, depending on the quality of the materials and how well it is maintained. Showers that are used frequently and exposed to hard water or mineral buildup may need to be replaced more often, while showers in homes with soft water and less use can last closer to 15 years.
The key factors that affect a shower's lifespan are the quality of the shower head, valves, and plumbing connections, as well as the overall condition of the shower enclosure. Regular cleaning, maintenance, and prompt repairs can help extend the life of a shower.
