When I walked into my client's 1940s bungalow bathroom, I nearly tripped over the tub. The room measured barely 1.8 by 2.4 meters. A toilet sat jammed against the vanity, and the shower curtain clung to your legs like wet seaweed. Every surface was beige and grimy. The owners, a young couple with a toddler, had been avoiding this room for years. I get it. Small bathroom renovation projects feel like squeezing a king-sized bed into a child's playhouse. But here is the truth: a tight floor plan forces discipline. You cannot waste a single centimeter. You cannot hide behind grand gestures. You must solve real problems with precision. That tiny bathroom had no storage for towels, no room for a hamper, and a vanity door that hit the toilet bowl if you opened it too far. We stripped everything down to the studs. The first decision was the hardest: ditch the tub, install a curbless shower with a linear drain. That single move reclaimed 40 centimeters of precious wall space.
