Though a shower seems to be one of the few ignored places when it comes to home decor, it still needs a considerable attention. Owing to the high levels of moisture to which the bathroom is subjected, one needs to take care of every element in this room. Special measures need to be taken if you have an elderly person or children in the house who share the same shower. Many people install grab bars in their showers so that old people can hold on to it and are prevented from a fall. These bars, though robuts, tend to wear after a certain time at which they need to be replaced.
Since the bars are well drilled into the wall, one should unscrew the bar & the mounting from the wall. Use silicone caulk to fill the created holes. Mark a new place for your new grab bar. Screw the bracket & then attach your grab bar.
