Speed starts before demolition
The fastest jobs are not rushed. The room has been measured, the scope is agreed, your choices are ready and access is clear before site work starts.
Late choices and products that are out of stock can add more time than a good plan takes.
Do not remove the necessary sequence
Floor protection, demolition, prep, plumbing and electrical work, waterproofing, tiling, fitting work and final clean each have a place in the plan.
Cutting prep or curing time adds risk. Ask how the plan leaves enough time for each stage.
Ask for a realistic programme
A useful work plan shows what must happen first, when you need to make choices and how changes affect timing. It should fit the room rather than promise the same number of days for every job.
A clear written scope is the best way to start a fair talk about timing.
