What it is
Bathroom design planning: waterproofing, layout, and maintenance is a planning topic. The goal is not to memorize rules. The goal is to make decisions in the right order so the build is predictable.
Why it matters
When this is planned well, your project feels calmer. The schedule becomes easier to protect and the budget becomes easier to control.
Step by step approach
- Finalize selections before installation weeks
- Choose a layout that improves circulation and reduces clutter
- Plan lighting layers and switch locations
- Document details so the build matches the vision
- Define the desired feel with three words and a simple palette
- Map routines, clearances, and storage needs
- Review quality with a punch list and closeout folder
Use this list as a decision sequence. Planning time is cheaper than construction time.

- Use a consistent grout strategy and movement joints
