Why does my shower drain keep blocking in my Dubai apartment?

Slow and smelly shower drains in Dubai apartments are extremely common and have two main causes: Dubai's hard water — the high mineral content in Dubai's water causes calcium and soap scum to build up inside the drain pipe, progressively narrowing it until flow is severely restricted. This is the primary cause of the slow drain. The smell — in Dubai's heat, the organic matter trapped in the buildup (hair, soap, skin cells) decomposes rapidly, causing sulphurous smells. Chemical drain cleaners only partially dissolve the buildup and don't address the underlying hard water scale. The permanent fix: A plumber uses a high-pressure hydro-jet to blast through the buildup and clear the entire drain pipe — not just the surface blockage. This costs AED 150–AED 350 and typically lasts 1–2 years before repeat treatment is needed. Prevention between professional cleans: Use a hair trap over the drain to reduce organic buildup. Monthly: pour boiling water down the drain, followed by a cup of baking soda and then a cup of white vinegar, leave for 30 minutes, then flush with hot water. This dissolves minor soap scum buildup before it becomes serious. Install a shower head filter — reduces mineral content in the water and slows scale buildup in both the drain and the shower head. If the drain is the landlord's responsibility (it is, as it's part of the building's drainage infrastructure), report persistent slow drains in writing.
