Are there any experts out there who could advise me on brass vs zinc construction for things like towel bars? We're building our forever house on Martha's Vineyard, and while we're not on the water, the air is still salty and things tend to corrode faster than normal. Prices for bath accessories seem to be all over the map, regardless of construction. Anyone out there live near the ocean, and have experience with how the finish holds up for your bath stuff? Thanks!
