Common red flags in bathroom remodel quotes
These are the most frequently omitted or vague items. Any of them in your quote should prompt a follow-up before you sign.
No waterproofing line item
Waterproofing is non-negotiable in a shower or wet area. If it's not explicitly listed, ask — skipping it leads to mold, water damage, and expensive repairs.
Plumbing scope not itemized
'Plumbing included' means nothing without detail. Are fixtures just being re-connected, or is there rough-in work? Moving pipes can double the labor cost.
No permit line item
Bathroom remodels involving plumbing or electrical work require permits in most jurisdictions. Missing permits can cause issues at resale.
Fixture brands or specs not listed
A quote that lists 'toilet, vanity, faucet' without specifying model or quality tier can result in builder-grade fixtures when you expected mid-range.
Tile not specified
Tile costs range from $1/sq ft to $30+/sq ft. If the quote just says 'tile work' without material specs, you have no basis for comparison.
Three things to confirm before signing any contract
These apply regardless of project type and are the final checks before you commit.
Payment schedule tied to milestones
Never pay more than 30–40% upfront. Each subsequent payment should be tied to a defined milestone — completion of demo, rough-in, finish work, final walkthrough.
All permits identified and assigned
The quote should clearly state which permits are required and who is responsible for pulling them. Unpermitted work can affect your insurance and resale.
Warranty terms in writing
Get both manufacturer warranty details (on materials) and a contractor labor warranty (on the work itself). Verbal warranties are unenforceable.
