Before buying this type of equipment, think about what your needs are. Are you having trouble using the toilet? Are showers becoming more difficult? Do you miss taking a bath? Are arthritis and weakness affecting your ability to care for yourself? You should discuss your needs and choices with your doctor too.
Tall toilets have seats that are 16″ to 20″ from the floor to help elderly people get off the toilet easier. Before buying a new toilet, know how much space you have, how tall you need it to be, what style of bowl you prefer, the flushing system needed, and what your price range is.
Some easier and cheaper options to replacing a toilet are using elevated toilet seats, installing a riser under your existing toilet, using a toilet safety frame, putting a commode chair over the toilet, or even using a powered toilet lift.
