that bathroom photo looks 100% better than the current bathroom photo.
I would move the shower curtain out of sight for the photo though.
Yes it needs updating, but like the kitchen, it is live- able.
I do find mn are quick to say things need replacing, but we moved in here 10 years ago. Ideally both bathroom and kitchen needed updating, we didn't have a budget, so we replaced doors, painted, fiddled with shower, painted over yellow pine etc etc and made perfectly nice bathroom and kitchen for us.
Not everyone will want/need to update, but the en-suite with the dark red tiles really does need to be done. (not by you) It is good to show that the other bathroom is more neutral.
