Our 25 year old bathrooms are in need of a tub and shower refurbishing and I am wondering what the general opinions are of using the acrylic liners instead of a total redo. I have a shower in one bathroom and a shower/tub in the other. Haven't looked at pricing yet but am guessing the liners are cheaper. Both are fiberglass or some kind of plastic so I don't think re glazing is possible. Any thoughts?
