Do-it-yourselfers can reap big savings with recycled or lightly used fixtures and building materials. Habitat for Humanity operates about 400 ReStores nationwide, which offer salvaged materials at half off home-center prices. One caveat: Many contractors won't work with salvaged items, or homeowner-supplied materials in general, because they don't want to assume the liability if something goes wrong. That said, if you're doing your own work, you can find anything from prehung doors to acrylic skylights to partial bundles of insulation. (To find a ReStore near you, visit habitat.org.)
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.
