Bathroom remodel checklist: every decision, in order
The short answer
A bathroom remodel goes smoothly when decisions happen in this order: budget and scope, layout, plumbing and electrical plan, waterproofing and tile choices, vanity and fixtures, lighting and ventilation, then finishes. The expensive mistakes all come from deciding out of order, like choosing a freestanding tub before confirming the drain and floor can support it.
Print this page and work down it. Each stage locks something the next stage depends on, and the checklist marks the points of no return, where a change of mind stops being a preference and starts being a demolition cost.
Keep one folder, physical or digital, with the contract, permits, product list with model numbers, and this checklist with dates. That folder is the project.
Stage 1 to 3: money, space, systems
- Set the total budget, then reserve 10 to 15 percent as untouchable contingency
- Decide the scope honestly: cosmetic, pull and replace, or layout change
- Measure the room and sketch the layout, drain and door swing included
- Confirm the tub versus shower decision, see our comparison guide
- Get three bids on the same written scope
- Verify licenses, insurance, and the permit plan with your city
Stage 4 to 6: surfaces, fixtures, air and light
- Choose tile and waterproofing system together, they are one decision
- Order the vanity early, it is the most common lead-time delay
- Pick fixtures in one finish family, with model numbers recorded
- Size the exhaust fan to the room and confirm it vents outside
- Plan lighting in layers: ceiling, mirror, and one warm source
- Order everything before demo, and inspect deliveries on arrival
Stage 7: build and close-out
- Photograph open walls before they close: pipes and wires, for future you
- Get the glass measured only after tile is complete
- Walk the punch list with the contractor before final payment
- Collect warranties, leftover tile (keep a box), and paint codes
- Register fixtures, file permits as closed, update your home records
Questions homeowners ask
What do people forget most often?
Ventilation and storage. A quiet, properly vented fan prevents the mold that ruins new bathrooms, and a remodel that deletes the linen niche without replacing it is regretted daily.
How much contingency is enough?
Ten percent for a cosmetic scope, fifteen for a gut remodel, twenty for homes built before 1970. Unused contingency is a refund to yourself, not a loss.
When do I pay the contractor?
In stages tied to completed phases, never fully in advance, with the final payment only after the punch list is done. Get the schedule in the contract.
