People focus on tiles and forget about grout, yet grout lines are everywhere in the bathroom. White grout looks clean at first but stains easily in busy bathrooms. Dark grout hides dirt but gives a more defined grid look.
Choose grout color based on:
how much cleaning you realistically do
tile color and size
the overall style you want
Also ask for good-quality, mold-resistant grout. Cheap grout cracks or discolors quickly, making a new bathroom look old in months. Small decisions like grout color and type often determine how long your renovation keeps its “fresh” look.
