When renovating a bathroom, there are several key areas that require special attention. Firstly, the plumbing and drainage system are crucial. Ensure proper installation to prevent leaks and pressure issues. Additionally, ensure the drainage system is clear to avoid clogs and water leaks.

Secondly, choosing suitable tiles and waterproof materials is essential. Opt for water-resistant and easy-to-clean tiles, and use waterproof materials on walls and floors for long-term durability and moisture protection.

Thirdly, lighting is a factor to carefully consider during bathroom renovation. Ensure sufficient natural light enters the space and consider the selection of fixtures to provide adequate brightness and create a comfortable ambiance.

Lastly, layout and storage are important considerations. Ensure proper placement of the sink, toilet, and shower area, and consider storage space such as cabinets or shelves for toiletries and towels.
