How to Compare Three Bathroom Renovation Bids Line by Line

Start from identical specs

California's licensing board recommends collecting bids built from the same plans, specifications and scope of work, rather than letting each company define the job its own way.^[1]

Without that step, three bids for a bathroom remodel are really three different projects wearing the same label.

Treat a suspiciously low number as a question, not a win

That same guidance flags a bid landing far below the others as worth extra scrutiny, since it often signals a missing line item, a lower-grade material substitution, or a mistake in the estimate itself.^[1]

Compare more than the total

Washington's Department of Labor & Industries frames the comparison around scope, warranties, references and timeline, not price in isolation, when weighing multiple written bids against each other.^[2]

Confirm the license on the page, not just the pitch

A legitimate bid carries the company's license number printed on it, the same number a state lookup tool can confirm independently before you sign anything.^[1]

Read the allowances, not just the headline price

An allowance is a placeholder budget for a fixture or material you have not picked out yet, tile, a vanity, a faucet. Two bids sharing the same bottom-line total can still carry very different allowance amounts, which changes what you actually get to choose later on.

Ask what is excluded, in writing

Permit fees, disposal costs, and repairs to anything discovered once demolition starts are common exclusions. Getting each company to state its exclusions in writing is what makes three bids genuinely comparable.

A bid silent on exclusions is not necessarily hiding something, but it leaves more room for a surprise invoice once the wall comes open.

Line up the payment schedule too

A bid's payment schedule is as much a part of the comparison as its total. Washington's guidance favors payments tied to completed phases of work over a calendar schedule, which is worth checking line by line across all three bids, not assuming is the same from one company to the next.^[2]

Put the timeline in writing as well

A start date and an estimated completion window belong in the same written comparison as the price, since a cheaper bid that runs twice as long is not automatically the better deal once your household has gone without a working bathroom that whole extra time.

Keep the comparison on paper, not in your head

Three verbal conversations are much harder to compare fairly than three written bids sitting side by side on the same page, scope item by scope item, dollar by dollar.

Questions people ask

Should the cheapest of three bids automatically lose points?

Not automatically, but it deserves the same scrutiny cost guides recommend: confirm it is built from the same scope and materials as the others before assuming it is simply the better deal.^[1]

Is it reasonable to ask a company to match a competitor's format?

Yes. Asking every company to quote against the same written scope is standard advice, not an unusual request, and it is the only way the three numbers end up meaning the same thing.^[1]

How many bids are actually worth collecting?

Three is the number state consumer guidance tends to anchor on, enough to spot an outlier in either direction without turning the process into a part-time job.^[1]

Is it worth paying a company just to draw up a detailed scope first?

For a complex layout change, a paid scope or design phase can pay for itself by making every bid that follows genuinely comparable, rather than three different companies guessing at the same vague idea in three different directions.
