Water Bottles from Fridge to Room Temp!

Hello everyone, forgive me if this is the wrong place, or if the question is silly, We are doing repairs at home and won't be able to drink the tap water, so i bought a few bottles of water to take home, When i bought them at the store, they were cold, but when i got them home i let them rest at room temp for the past few days (unopned!) is it still safe to drink?
