What are the recommended guidelines for bathroom grab bar placement to ensure safety and accessibility?

The recommended guidelines for bathroom grab bar placement to ensure safety and accessibility include installing bars near the toilet, shower, and bathtub at a height between 33-36 inches above the finished floor. Bars should be securely anchored to support at least 250 pounds of weight and have a diameter of 1.25-1.5 inches for a comfortable grip. Bars should also be placed horizontally or diagonally for optimal support and stability.
