Kitchen sink crack

I got a crack in my plastic sink a couple of years ago. Got a 2 part urethane patch kit, sanded around the crack lightly, drilled a tiny hole at each end of the crack to keep it from running, mixed a little color in it and was done. Dried and cured an about 30 min. Also did the same on a crack in the bathtub on a previous unit that I kept for 3+ years that never leaked or ran. Cost about $8.00 and 20min work.

I had a crack in my sink also, and replaced the sink with a stainless one. I could not find the exact size, but the one I found was about one inch smaller than the cutout (long ways from right to left). I put flat aluminium on both sides to cover the gap. I had to make sure the sink was not too deep so it wouldn't hit the drawer under the sink.

Thanks for the responses. I am leaning towards trying to find a stainless one that is the same size and replace. If I don't get to it before the next trip I will tape and glue and use carefully.

Replace it. I've done that and, at least in my case, the cost was very reasonable. Pretty easy DIY project. Had to do kitchen and bath in a previous TT.

I dropped a hammer in the shower and caused a hole about the size of a dime right where the water wants to go. Picked up something like the following from Home Depot. Repair was easy and almost a perfect match. Solid repair with no leaks for three years. Don't ask how the hammer managed to get into the shower....: Shower and Tub repair

In the short term you could probably patch it with silicone caulk or duct tape the underside of the sink. But long term I would replace it.
