When to use the grout tool
The Grout tool is built for practical bathroom planning. It helps estimate grout needed by tile size, joint width, tile thickness, and area, while keeping the calculation tied to the actual work rather than a generic remodel assumption.
It is most useful when the project is still being shaped: measurements are close but not final, product grades are not fully selected, and the homeowner wants a clearer brief before comparing suppliers, materials, service companies, or contractor quotes.
