What are the pros and cons of walk-in bathtubs for senior homes?

Walk-in bathtubs offer low-entry access, built-in seating and optional comfort features such as jets and heated backrests. The trade-offs include the purchase and installation cost, waiting inside while the tub fills and drains, and possible changes to hot-water, electrical or plumbing systems. Check the door swing and transfer space as well as the tub's footprint. A walk-in tub may suit your bathing needs, but it does not guarantee fewer falls, lower medical bills or a higher resale value.
