Using drywall instead of cement board for a shower is highly discouraged. In shower areas, moisture resistance is crucial. Drywall, even if it's the moisture-resistant type (green board), cannot withstand the high levels of moisture and water exposure that showers receive. Cement board is designed for wet areas; it does not deteriorate, swell, or mold with moisture, making it the superior choice for shower walls. For a lasting and mold-resistant shower, always opt for cement board over drywall.
