Bathroom assists

Delta toilet paper holder with grab bar - search on amazon. Several styles and finishes come up.

Amazon.com: KOHLER 25875-0 Hyten 3" Height, Elevated Soft Close Elongated Toilet Seat, Contoured Seat with Grip-Tight Bumpers, Quick-Attach Hardware, No Slam Toilet Seat.

Both items come in different colors to match your other bathroom fixtures, and do not look like “handicap assists”. But both are useful for people with Parkinsons - or just seniors - to give a little help when needed.
