Planning to add a new bathroom on an existing suspended concrete slab.
Here is my planning checklist
- Rough dimensioned layout sketch
- Basic 3D Project Schematic design
- Have an idea of what you want to spend overall “Budget” include all costs. These can be broken down to Fixtures, Materials, Labour, Tools/Plant, Profit, Time, etc.
- Use a planning template ie checklist, flowchart, spreadsheet/app
- Follow installation work sequences/ schematics carefully
- Optimisation, Design Style & Functionality is a function of Cost
- Consider Scale, Measurements & Future Accessibility requirements
- Lighting, Ventilation, Cleaning and Long term maintenance
- Also check regulations, local compliance & code specifications
Planning & knowing what’s involved is part of the “DIY process” or you can choose to leave it all up to a professional designer.
