I really screwed up. I put a t-shirt in bathroom sink, put the stopper on and turned on the water. I got a call and was distracted. Came back 30 min later and found the overflow drain doesn't work. It must be plugged up somehow but don't know how. The vanity has 2 sinks and is about 5 feet long with several drawers. 2 of the drawers were full of water and the bathroom floor was flooded! One of the drawers, made not with solid wood but that filler material, has partially disintegrated. It will be difficult to glue it back and still fit the rollers that go in and out, esp because the boards are somewhat warped from water damage. Can't replace the entire vanity for one drawer. Where would one be able to replace just the drawer or do I have to hire an expensive cabinet maker to build a new one. I feel really disgusted with myself over this.
