Linoleum bathroom floor

I wonder if the floor has delaminated and the top layer is now stretching. How old is it and is it a name brand? I would go back to the retailer and see if they will address the problem. I hope its still under warranty.

I agree! It looks like the top layer separated from the bottom layer and stretching. Especially if it was glued down. More likely cause from traffic. Would need to be replaced.

Well, judging from the fact that's it's in a corner, im thinking that's not a very high traffic area. Do you have kids? Cuz if I'm being honest, it looks like someone was pushing against the linoleum with their heels. The other commenters are right though, that's defiantly separated. And defiantly needs to be replaced. I did my grandparents master bath with peel and stick linoleum tiles, super Cheap. Think I paid around 40 to do the entire bathroom. Might be worth looking into

In the mean time, if it is not under warranty....try removing the quarter round and see if another coat of glue (maybe contact cement) and some smoothing and pressure would remove the wrinkles. Then trim the excess that you have pushed toward the wall edge. To me it looks like the installer left too much butted against the wall and it has eventually lifted and wrinkled.

This is rolled vinyl. There is no underlayment attached to it. If there's no water, is there excessive heat such as from a dishwasher? Either way, this needs to be taken up and replaced. Sorrry.

Had the same thing happen in our kitchen and breakfast room. It was armstrong and hey made it good. Said it was a mystery.

I would definitely pursue a solution from the product manufacturer, find the warranty or contact who installed it for you, call their 800 number. Do this before you do any home repairs yourself as that might void the warranty.

its gotta go
