Yes, you can tile straight onto plasterboard in a bathroom, but preparation is key. Plasterboard can support the weight of tiles, making it suitable as a backing material. However, ensure the plasterboard is firmly fixed to the wall studs, and the surface is clean and dust-free. For areas that will be frequently wet, such as shower areas, it's recommended to use a waterproofing membrane or a specialized tile backer board instead of regular plasterboard to prevent water damage. Using the right adhesive is also crucial for a lasting installation.
