A suction bar is not a grab bar, and treating it like one is how people fall in the shower.
Verdict
Never use a suction grab bar to take body weight. Suction cups can release without warning, particularly on textured tile, on grout lines, or as the seal degrades, and a release while someone is transferring in a wet shower is exactly the fall you were trying to prevent. A permanently mounted bar, screwed into studs or a proper backing, is the only kind that belongs anywhere a fall is possible.
This is the one comparison on this site where a wrong answer has a specific and serious consequence, so the safety part goes first.
A correctly installed grab bar is required by ADA guidance to withstand 250 pounds of force, and it is fixed into structure. A suction bar relies on a rubber seal against a smooth surface. Manufacturers themselves generally describe them as balance assists rather than weight-bearing supports, and their instructions say to check the indicator before every use, which tells you what they think of the seal's reliability.

Anywhere a fall is possible: entering and leaving a bath or shower, beside the toilet, at a step. Mount into studs, or into blocking installed behind the wall, or use a purpose-made toggle anchor rated for grab bars. Drywall anchors alone are not adequate. If you are not confident locating structure, this is a job for a handyman or a contractor, and it is an hour of labour rather than a project.

Light steadying only, by someone who is fully weight-bearing and would not fall if it let go. Suction bars are genuinely useful for a temporary situation, a hotel room, or as a visual cue for where to place a hand. Fit only to smooth, non-porous tile with no grout line under the cup, check the indicator before every single use, and reseat it regularly.

Placement matters as much as fixing. Bars are generally recommended horizontally or at a slight angle beside the toilet and inside the shower or bath, positioned where the person actually reaches rather than where the tile pattern suggests. An occupational therapist will assess the real bathroom and specify positions, and a referral is usually available through your parent's doctor. Never use a towel rail, a soap dish, a shower door or a curtain rod for support: none of them are anchored for it and all of them have caused injuries.
Not as grab bars. They are balance assists that can release without warning, particularly on textured surfaces, over grout lines, or once the seal degrades. Manufacturers generally say the same in the small print. For anything where a release would cause a fall, only a permanently mounted bar is appropriate.
Yes, with purpose-made anchors rated for grab bar loads, or by fitting blocking behind the wall. What is not adequate is ordinary drywall anchors. If you are not sure, have it installed by someone who is: the cost of an hour of labour is small against the cost of a fall.
ADA guidance requires a correctly installed grab bar to withstand 250 pounds of force. That figure assumes proper installation into structure. A bar rated for 500 pounds and screwed into drywall holds nothing in particular.
Typically beside the toilet, inside the shower or bath, and at the entry point where the person steps over. Exact placement depends on the person's height, reach and how they actually move, which is why an occupational therapist assessment is worth requesting through their doctor.
