Hold a bar in one corner following the tape that you have marked on the stud.

In the same way, hold the second bar in the right position.

You have to trace the perimeter between the two bars.

Step 4: Mark the holes-

 Holding the bar in the right place, you have to mark the dots.

Be careful when you are marking the dots. The dots are the indicator where to make holes.

You can use a pencil to trace the circles and marks.

Step 5: Drill 1/8 inch-

Take the drill machine at the dots that you have marked a few minutes ago. Make a 1/8 inch hole.

Now insert a nail or anything like that to be sure the hole is over a stud.

Step 6: Make a 2-inch hole-

It is time to make a hole into the fiberglass. Look at the shower we have traced circles.

Make a 2-inch hole with a 2-inch hole saw.

Do not go deeper exceeding the actual measurement of the hole.

Take the silicone caulk in your hand. Pour a bit of silicone caulk around each hole in the fiberglass.

Try to bead a good amount of caulk so that it can block the unnecessary holes.

Step 11: Insert the mounting bracket-

Insert the mountain bracket to fix with the mounting spacer.

Get the disk sides of the bracket facing onto the spacer so that we can put the screw in the right place.

Get a screwdriver and place it on the screws. Make sure the mounting bracket disk reaches the fiberglass wall.

Put the screws in the disks.

Step 12: Adjust the holes-

Adjust the alignment between the disks and the shower wall. Check out the screws whether they are in the exact position.

The grab bar and the mounting brackets must stand in a single line. If not, shake the bar a little bit to adjust.

Finally, drive the screws through the holes using the screwdriver. Turn the screwdriver until it is tight enough.
