Ok, so I'm REALLY clumsy in the mornings. And the evenings. And at night. Additionally, I'm renting a room in a friend's house.
So one morning I fell in the shower (again) except I didn't use only the handles that the previous owner had put in for this very thing... I got up using one handle, and one soap dish. Said soap dish came out of the wall in my hand... and well, I've gotten good at fixing what I break. I'm proud of this work!
The Damage:

The old grout needs to be chipped off,

and the whole thing sanded and cleaned with bleach.

Then, you smear glue all over the place. Use way too much, so it squishes out the sides.

Then, shove it all back in place,

tape it up so everything stays put...and wait 24 hours to shower.
But wait, since the shower is gonna be off limits for another whole day, lets repair the leaky towel bar too!

This one I had to pry out of the wall, but it was wobbly and probably leaky. So now, the bathroom is fixed! This was seriously easy.
I hope this is in the right place!
