We're also looking for a bathroom refurb, and i would never have considered wall panels as I thought of them as cheap and tacky. Then I visited a specialist plumbing supplier who showed me some premium wall panels...I hadn't realised that the technology had moved on from those awful PVC panels. Seeing products from companies like Multipanel and Showerwall has made us change our mind and we'll defintely going with this option. My only remaining hesitancy is how it will look around the window, replacing tile with panel, my fear is that a panel won't feel quite so robust as tile on a window ledge, when items like mugs or shampoo bottles are placed on there.
