Understanding Why Bathroom Renovations Cost So Much

Everyone loves saying “It’s just a small bathroom, why is it so expensive?” The truth is that bathrooms involve almost every trade in construction: plumber, electrician, tiler, carpenter, painter, waterproofing specialist, sometimes mason and glass installer too. Each one charges separately.
The real cost isn’t the tiles — it’s the labor and preparation. Waterproofing layers, cement screed, plumbing corrections, electrical rewiring, leveling the floor, then tiling… all that happens before the part you can see.
Another reality is unplanned discoveries. Old houses often have:
rusted pipes
leaking joints
uneven floors
non-standard drain sizes
wiring that’s unsafe near water
Once exposed, these must be fixed. That’s why renovation rarely stays at the first estimate.
To avoid heartbreak:
ask for itemized quotations
set aside extra 20% contingency
don’t rush contractors who are doing waterproofing
choose reliable plumbing fixtures rather than just beautiful ones
Bathroom renovation isn’t expensive because people want to scam you — it’s because water plus electricity plus small spaces require precision and safety.
