What are the recommended installation guidelines for grab bars for tubs to ensure safety and accessibility?

When installing grab bars for tubs, it is recommended to place them securely on the wall at a height of 33-36 inches above the tub floor. Make sure they can support at least 250 pounds of weight and are anchored into wall studs for stability. Additionally, consider placing grab bars near the tub entrance and along the length of the tub for easy accessibility and safety.
