I have just moved into a condo which has been empty for probably one year. I am wondering if the
shower grout would still be patent after not being used for this length of time. It looks fine otherwise, no cracks
or obvious deficits. In a previous home I used a spare shower as storage for a few years, and when I began to
use it for showering again I quickly found that it leaked, so not sure what is a safe time frame for this unused shower grout.
