Rotten wood bathroom skirting board

[ChocoholicsAnonymous]

Bit sure what to do about it/how to solve. Any advice please?

not

Do.you know why it is rotten? Can you post a photo. Shouldn't be too difficult to replace, but if there's a leak or problem that needs dealing with too than there's no point just replacing the skirting.

It's right next to the bath.

Ours had rotted due to a tiny tiny leak in the shower screen sealant

Pop off the bath panel and have a look to see if there's any water leaking underneath. Keep an eye out for drops of water post shower.

Even a tiny bit will cause the skirting board to rot.
