Apartment tub crack
I was showering and took a step back towards the shower head and heard a cracking noise. I pull up the shower mat to see this mess of a crack. I stopped the water quickly and got right out to avoid making it worse. My apartment complex only came out and took a photo and hasn't done anything to repair it in the week and a half since. It has been radio silence from them so I have no idea what their plans are.
I'm wondering why the tub would Crack like that? I haven't experienced anything like that before and i am worried my apartment will try to say that I damaged the tub through unusual activity and try to charge me for it. I am around 300 lbs and have never had any issues with tubs/showers before. My apartment is on the first floor with concrete foundation if that makes a difference.
