Many DIY enthusiasts install standard gypsum boards themselves. For moisture-resistant and humidity-prone areas, a careful DIY installation is possible, but you may prefer a professional for precise cutting, accurate jointing, and finishing to ensure long-term durability in damp spaces.

Use proper studs, cut boards accurately, seal all joints with moisture-appropriate joint compound and tape, finish with a compatible skim coat or paint, and ensure good ventilation in damp spaces to minimize prolonged humidity exposure.
