About 2 years ago we some repairs done in the bathroom which included installing a new vinyl floor. Everything seemed fine except the flooring is crooked. About 6 months ago, I noticed there was a slight raise in the flooring nearest the bathtub. It's not spongy but you can tell there is a raise under the flooring. This area had a spongy spot that was fixed with a piece of wood before the vinyl was laid.

No telling what's going on down there but it must come out under any circumstances. I suspect that wjhaever caused the spongy spot before is still active, likely a bad drain or supply line.

Before you remove the floor and start over, take a small section of 2x4 place it over the bumps and try to flatten with a hammer. Good luck:)

I tthink you need to consider taking up the floor. I have had zero luck getting warped floors to reflatten. Remove the flooring and lets see what causes the moisture, I'd suspect maybe a bad drain line or even a supply

I did a bathroom where the tub overflowed and soaked into the sub-floor. It was never repaired. Flooring guys put a new sub-floor and laminte over it. I had to tear up two layers of the floor. Then had to cut a 4x4 out of the floor as it had BLACK mold on it.
