Both get rid of the high tub wall that causes so many bathroom falls. After that, they go in opposite directions.
A walk-in tub keeps the bath and adds a door and a seat. A curbless shower drops the step entirely, so a person walks or rolls straight in. One protects a habit someone loves. The other plans for the day a walker or a wheelchair comes into the room.
Walk-in tub
Best for: Someone who bathes for comfort or for sore joints, who can still lift a foot over a low threshold and wait while the tub fills and drains.
Typical cost: $3,000 to $20,000 (ConsumerAffairs 2025).
Pros
- Keeps a real soak, which some people will not give up.
- A built-in seat means nobody lowers themselves to the tub floor.
- Fits in the footprint of the tub that is already there.
- A walk in tub with shower, the combo most models offer, adds a handheld shower so a person can rinse from the seat.
Cons
- There is still a ledge to step over at the door.
- You sit inside while the water fills and again while it drains, which can mean a cold wait.
- It does not work for a wheelchair and is hard with a walker.
- A walk in tub with jets brings a pump, which needs power near the tub and regular cleaning.
- The published range runs higher, at $3,000 to $20,000.
About bathroom safety and remodelingCurbless shower
Best for: Someone who uses or may soon use a walker, a shower chair or a wheelchair, or who has a helper in the bathroom with them.
Typical cost: $2,000 to $15,000 for a tub to curbless or walk-in shower conversion (HomeGuide and Angi 2025).
Pros
- No step at all, so feet and wheels cross the same level floor.
- Room for a seat, a handheld shower and a helper standing beside the person.
- Still works if mobility changes next year.
- The published range starts lower, at $2,000 to $15,000.
Cons
- The bath is gone, which can feel like a real loss to someone who loved it.
- The floor has to be built to slope to the drain, so it is a bigger construction job than swapping a tub.
- Water control needs careful planning in a small room.
About bathroom safety and remodelingHow to decide
Ask the person who will use it first. If giving up baths would make them stop bathing, that answer matters more than any chart.
Then think about the walker. Anyone who uses one now, or is likely to soon, will find the shower easier every single day.
Finally, think about who helps. A helper can stand beside a shower chair. Helping someone in and out of a tub, even one with a door, is harder on two bodies. The assessment looks at the room and how the person moves, and lays out both options with written prices.
Questions families ask
Is a walk-in tub safe for someone who has fallen before?
It removes the high wall but keeps a step at the door, so it depends on how steady the person is. If a fall came from balance trouble, the shower usually carries less risk.
Can grab bars alone fix the tub?
Sometimes, for now. Bars, a transfer bench and a handheld shower can make the old tub workable while you decide on a bigger change.
How much does a walk in tub cost with shower?
A walk in tub shower combo usually adds a handheld shower on a slide bar and a diverter valve, so the plumbing part of the job grows a little. The tub you pick and the state of the walls behind it move the price more than the shower does, and the written scope prices both together.
Which one fits a small DC bathroom?
Either can fit where an old tub stood. A curbless shower usually leaves more open floor, which counts in a tight rowhouse bathroom.
