Look at your countertops next. “Limited counter space is always problematic in tiny bathrooms,” Maykut says. Often, you're left with nowhere to set a cup of tea or lay down your curling iron. One creative solution for gaining space is choosing a custom countertop. While most bathroom configurations place the vanity next to the commode, Maykut suggests “extending a narrow ledge of countertop along the wall behind the toilet.” This otherwise wasted space is just right for a supply of tissues or an assortment of toiletries.
