A walk-in bathtub has a sealed door and a built-in seat, so your parent sits down before the water fills. That's lovely for soaking sore joints. The catch is that they sit in the tub while it fills and drains, so a fast drain and a heated seat make a real difference to comfort. Ask each installer how long a full drain takes on the model they're quoting.
There are some Burlington details to plan around. Older homes downtown and in Aldershot can have small bathrooms and older plumbing, so ask whether the drain, supply lines and floor need work first. A deep tub holds a lot of water, so your hot water tank may need to be larger or swapped for a tankless heater. In a lakeshore condo, ask the condo board about rules for plumbing work and water shut-offs before you book.
Prioritize installers who do accessible bathrooms often, not just general renovations. Look for a low step-in, an anti-scald valve, grab bars built in, and an inward or outward door that suits your parent's mobility. Ask for the warranty on the door seal and pumps in writing, plus who services it locally. A leaking seal is the most common complaint, so local service matters.
Here's our honest view. A walk-in tub is the right choice when bathing is part of how your parent relaxes or manages pain. If they mostly shower, a walk-in shower is simpler, quicker to use and usually costs less, so compare both. Walk-in tubs in Canada are sold mainly through a handful of brands and dealers, and Burlington families often get quotes from Hamilton and Oakville installers too, which you'll see nearby.
