One option is to install grab bars next to the toilet and in the shower. This will ensure that those who have difficulty standing or balancing can safely hold on while using these facilities. Another modification you can make is to replace the standard doorknob with a lever-style doorknob. This will provide easier access for those who have trouble gripping or turning traditional doorknobs. Finally, consider installing a raised toilet seat which will make it easier for those who have difficulty getting up and down from the toilet.
