Was wondering if I could leave a brush inside the shower stall. Will constant humidity cause the bristles to breakdown or the glue to loosen? I was considering buying a synthetic for that purpose.
+1 on the mildew aspect. I'd never leave a dense brush in the shower for an extended period of time.the main concern IMO would be the bristles not drying completely and the resulting mold/mildew buildup. A synthetic would be best for a shower brush, but you'd probably want to give it a thorough cleaning once a week or so
