Many leaks don’t show immediately. Everything looks fine until after some months — then tiles get damp, paint peels, or bad smell appears. This usually happens because of rushed or careless plumbing hidden inside walls and floors.
Insist that plumbers:
pressure-test pipes before closing walls
use proper adhesive and sealants
avoid mixing different pipe types without fittings
slope bathroom floors correctly toward drains
Buy quality valves, traps, and pipes — not just shiny taps. The real hero of a bathroom is the plumbing you don’t see. Once hidden leaks start, repairs mean breaking tiles and walls again.
Good plumbing is invisible but priceless.
