Start with the person
An accessible bathroom starts from how one person moves: stepping over a curb, sitting to wash, turning a wheelchair, standing up from the toilet. A doctor’s or therapist’s advice shapes the plan more than a catalogue does. The request should say what is hard today. The company that calls can then propose the changes that match.
The usual changes
- Step-free shower. A curbless shower sits flush with the floor. One Ottawa firm says a traditional curb is 4 to 6 inches, and a curbless base takes a precise floor slope and waterproofing, so it is a bigger job. See walk-in shower.
- Blocking for grab bars. Bars hold when they screw into framing or solid blocking. Add it while the wall is open.
- Seat, hand-held head, valve. A fold-down seat or built-in bench and a hand-held shower head change how the shower is used. Ask the company about the valve too.
- Doorway and floor. A wider door and a slip-resistant floor matter before any fixture.
What it costs
Capital Bathroom Renovation puts converting a tub into an accessible shower at $15,000–$25,000 or more, a mid-range renovation with accessibility features at $20,000–$40,000 and a high-end one above $40,000. Bytown Bath lists a walk-in tub conversion at $2,400–$5,700 and a made-to-order therapeutic tub at $27,000–$30,000 plus tax. HomeStars’ Ottawa guide says moving plumbing adds $1,500–$5,000. The bathroom cost page puts these next to the general ranges.
Tax credit
The Home Accessibility Tax Credit is federal and non-refundable. It covers work that helps the person get into the home, move or function in it, or lowers the risk of harm there. The person must be 65 by the end of the year or approved for the disability tax credit. The expense ceiling is $20,000 a year, and a government grant leaves it intact. One Ottawa firm’s guide puts the 2026 rate at 14%, up to $2,800 a year. The tax credit page has the detail, and an accountant can say how it sits beside the medical expense credit.
City and provincial programs
Ontario Renovates, run by the City of Ottawa, combines two pieces for eligible low-income seniors and people with disabilities, $20,000 in all. The larger is a $15,000 loan, forgiven over ten years, for essential repairs or accessibility changes; the smaller is a $5,000 grant for accessibility changes alone. Forgiveness depends on owning and living in the house for ten years after the work. The provincial Home and Vehicle Modification Program applies to people with a disability under an income threshold and applies through March of Dimes Canada.
Timing and paperwork
Ontario Renovates asks for verified project quotes and rules out work started before approval, so the application comes before the contract. The CRA wants agreements, invoices and receipts that name the vendor, describe the work and show payment in full; ask the company to write the invoice that way from the start. Plan the order: funding approval, then the signed contract, then the permit if plumbing moves, then the work.
Who sends the written price
The Desk passes an accessibility request to one independent renovation company. It calls, sees the bathroom and puts the price in writing, in a form you can attach to a funding application. For a tight room, see the small bathroom page.
Questions to ask the company
- Which changes are in the price: curbless floor, blocking, bench, valve?
- Where is wall blocking for grab bars, and can it go anywhere later?
- Does the invoice carry the details the CRA asks for?
- Can you quote in two steps if the City program needs approval first?
- What is the door width, and does it change?
Have this ready for the call
- Who uses the bathroom, and any doctor's or therapist's advice on equipment.
- Door width, room size and the position of the toilet.
- Photos of the tub or shower and the route from the bedroom.
- Your age and tax status for the credit, or a funding application if relevant.
Questions people ask
Do I get the money before or after the work?
It depends on the program. The tax credit is claimed on your return after the work is paid. Ontario Renovates needs verified quotes and an approval first, and the City excludes repairs done before approval. Apply before you sign.
What does the Ontario Home and Vehicle Modification Program cover?
It funds home modifications for permanent Ontario residents whose disability impedes mobility and whose household income is under a threshold. Its examples include rearranging bathrooms to permit safe use and a wet room built to universal design. Applications go through March of Dimes Canada.
What details does the CRA want on the invoice?
It asks for the contractor’s name, address and GST/HST number if registered, a description and dates of the work, the address where it was done, the amount and proof of payment. Keep these documents; the return goes without them unless the CRA asks.
How long is Ontario Renovates money available?
The City of Ottawa says the funding is first come, first served until March 31, 2027. The program needs verified quotes and its approval before work starts, and it excludes work begun earlier, so the quotes and the application come before any contract. Ask the company for a written quote you can attach to the file.
Is a walk-in tub the only accessible choice?
It is one of several. A curbless shower with a seat and grab bars suits many households, and a door cut into the existing tub suits someone who still wants to sit in water. Ask the company to price two options side by side for the person who will use the room, and compare them with the ranges on this page.
