Remodel the bathroom to a walk in shower, or get a tub transfer bench or chair they can sit in, non slip bath mats, live in a house without stairs. Put in Nightlights. Rugs and changes in floor height are trip hazards. If you have stairs anywhere like to get in out of the house, make sure there’s a railing. Watch out for toilets that are too low. Can replace with a taller toilet or put a commode or something over it. Make sure they don’t have a big dog that will knock them over. Make sure the bed is easy to get in and out of, not too high or low. Clear pathways, no hoarding.
