I am updating my 1958 bathroom with floor tile etc. I have the original pink tub that is in ok shape (and hidden behind the shower curtain). I have new sink and toilet in white and am considering gutting the bath to studs and getting new tub. Cannot justify the cost of new cast iron so... do I go acrylic or fiberglass? Or do I reglaze the original. Cost is not the main issue. Thanks Houzz colleagues
