See how designer Emilia Wisniewski transformed an impractical seven-by-nine-foot bathroom into a bright oasis while staying on budget. She replaced outdated extras — like the locker-style storage and semi-circular shower — with floating shelves, a marble walk-in shower and matte black hardware for a clean and cohesive look. The new built-in storage, hidden hamper and sleek invisible drain in the shower keep the space clean and clutter-free. Plus, Emilia shares how she made a DIY vintage sliding door that brings character to the modern bathroom.
