If you are working on a budget and want a new look, consider changing out the worse element of a bathroom. Replace an old worn out discolored unit with a custom tile shower or nice new tub and glass door. This offers a facelift that won’t break the bank. New lighting is also a way to spruce up an outdated space.
If space is limited like in this narrow bath, consider installing custom shelves and cabinets between the studs for a new set back niche that is attractive as well as functional.
