An inexpensive, easy to care for raised toilet seat solves the problem quickly and easily. You might also want toilet safety rails, which give good support and added stability. Put a shower bench or stool in your shower and never worry about losing your balance again. Shower Benches come with and without backs. You can get an easy care white composite or plastic shower seats with aluminum tubing.
Some models come with padding or even a commode opening.
If getting into the bathroom is a problem, the handy bedside commode is just the thing. Put it next to the bed or anywhere you like. Of course bedside commodes are easy to clean and have removable buckets, too. Choose from a variety of styles and sizes. You can even have one painted to match your decor or painted with flowers.
