How to Compare Bathroom Renovation Quotes in Ottawa: A 2026 Checklist
Why two quotes for the same bathroom can be thousands apart, and the line items that tell you which one is the real price.
How do you compare bathroom renovation quotes? Put the quotes side by side and check that each one covers the same scope: demolition, waterproofing, the exact tub or shower system, fixtures, plumbing, permits, cleanup, timeline, payment schedule and a written warranty. A lower number often means something on that list is missing, and it shows up later as an extra.
For reference, Bytown quotes a tub-to-shower conversion or bathtub remodel at $13,000 to $15,000 CAD and a complete bathroom renovation from $20,000 CAD, on one fixed written quote after a free in-home assessment.
Getting three bathroom renovation quotes is good advice, but it only helps if you can read them. One contractor sends a single line with a total. Another sends three pages of items. A third leaves out the waterproofing entirely. For many Ottawa homeowners, the hardest part of planning a bathroom is not choosing the tile, it is working out which quote is actually the cheapest. This checklist shows you how to compare bathroom renovation quotes line by line, which gaps to watch for, and what Ontario’s consumer protection rules say about written contracts and estimates.
Why Bathroom Renovation Quotes for the Same Room Differ
Two quotes for the same Ottawa bathroom can describe two very different jobs even when they use the same words. These are the most common reasons the totals do not match.
Different scope behind the same words
“New shower” can mean a full tear-out down to the studs with new waterproofing, or a new base set into old walls. Until each quote lists what is removed and what is built back, you cannot compare the prices.
Allowances instead of named products
Some bathroom renovation quotes use an allowance, a set dollar amount for fixtures or tile that you pick later. If the allowance is low, the real cost rises when you go shopping. A quote that names the exact tub, wall system and faucet is easier to trust.
Items left out completely
Permits, disposal, plumbing changes, electrical work and repairs found behind the walls are the usual missing lines. Each one can add hundreds or thousands of dollars after you have signed.
Your Line by Line Checklist for Bathroom Renovation Quotes
Use these items to line up every quote you receive in Ottawa. If a quote is silent on one of them, ask the contractor to add it in writing.
Demolition and disposal
Who removes the old tub, shower, tile and vanity, and who hauls it away? Disposal should be included, not billed later.
Waterproofing
Ask how the wet area is waterproofed and whether new waterproofing is part of the job. This is the line that protects your walls and subfloor for years, and it is the one most often missing from a low number.
The exact products
Look for the brand or system name for the tub or shower base, the wall material, the valve and the fixtures. Our guide to shower wall surround options shows the kind of detail worth asking for.
Plumbing, electrical and permits
If plumbing moves, a City of Ottawa building permit may be needed, usually a few hundred dollars based on the number of fixtures. Electrical work such as a new fan or lighting circuit should be done by a licensed electrical contractor. See our guide on bathroom renovation permits in Ottawa.
Timeline, payment and warranty
A good quote states the start date, how long the work takes, the payment schedule and what the warranty covers, for both the products and the labour. Our bathroom renovation warranty guide explains the difference.
Red Flags When Comparing Bathroom Renovation Quotes
A single total with no breakdown
A one-line price gives you nothing to compare and nothing to hold the contractor to if the scope changes.
Pressure to sign today
A discount that disappears if you do not sign on the spot is a sales tactic, not a price. A fair quote is still fair next week, and reputable Ottawa contractors will give you time to compare.
No written contract or no warranty
If the contractor will not put the scope, price and warranty in writing, keep looking. For a broader screen of the company itself, use our contractor hiring checklist.
What Ontario Rules Say About Quotes and Contracts
Ontario’s guide for home renovation businesses, based on the Consumer Protection Act, sets out a few protections every homeowner should know before comparing bathroom renovation quotes.
Written agreements
A written agreement is required for any renovation contract worth more than $50, and it should describe the work, the materials, the total cost, the payment terms and the warranty.
Estimates
If a contract includes an estimate, the contractor generally cannot charge more than 10 percent above it unless you agree in writing to added or different work.
Cooling-off period
If you sign a contract in your home, you have a 10-day cooling-off period to cancel for any reason. This is general information, not legal advice, so check the Ontario guide or a lawyer for your own situation.

How to Compare Bathroom Renovation Quotes Step by Step
- Get at least three in-home assessments. A quote given without seeing the bathroom is a guess, not a price.
- Ask for the same scope from each contractor. Describe the same layout, products and finishes so every quote prices the same job.
- Line up the quotes item by item. Check demolition, disposal, waterproofing, products, plumbing, permits, cleanup and warranty on each one.
- Ask about every missing line in writing. Have the contractor confirm whether each gap is included or will cost extra.
- Compare timelines and payment schedules. Note the start date, how long the work takes and when each payment is due.
- Choose the most complete quote, not only the lowest. Pick the quote that covers the whole job, in writing, with a clear warranty.

Frequently Asked Questions
How many bathroom renovation quotes should I get?
Three in-home quotes is a good number. It gives you enough to see a fair price range without making the comparison too hard to manage.
Why is one bathroom renovation quote so much lower than the others?
A much lower quote usually leaves something out, such as waterproofing, disposal, permits or plumbing changes, or uses a low allowance for fixtures. Ask the contractor to confirm each item in writing.
Should a bathroom renovation quote be free?
Many contractors, including Bytown, offer a free in-home assessment and a written quote. A visit lets the contractor see the room, the plumbing and the condition of the walls before pricing the job.
Can a contractor charge more than the estimate in Ontario?
Under Ontario’s consumer protection rules, a contractor generally cannot charge more than 10 percent above an estimate in the contract unless you agree in writing to added or different work.
What should a bathroom renovation contract include?
It should list the work and materials, the total cost and taxes, the payment schedule, start and finish dates, who cleans up, and the warranty on both products and labour.
