How do I slightly darken laminated wet wall?

We are currently refurbishing one of the en-suite bathrooms in our home.Unfortunately one of the major wet wall panels is a lighter grey marble shade than the others.. and it is quite noticeable. It is too late to pull it off the wall without completely ripping out the adjoining panels. These are laminated panels.Is there a glaze or an oil that may help camouflage this colour difference.I would be so grateful for any suggestions other than "start again"

    Have you tried a poly-stain? I redid my bathroom cabinets with this in dark brown and they came out great!

      You may want to ask an associate at Lowes or wherever you go for suggestions also. This may not be the perfect option.

    Don't think anything will hold up in the wet area. Sorry

      Good Morning Kelli, again thank you for responding to my question.

      As you can see Robin has suggested a poly-stain, which I will try.

      Nothing ventured as they say
