In these challenging economic times and with home prices falling to where they are, you need to be practical with the dollars you spend on your bathroom renovations.  If you can manage to replace your bathroom fixtures rather than relocate them you will save a tremendous amount of money.  Plumbers are trademen that have the tendency to charge the most for their time so if you have a limited budget "rip and replace" rather than "rip and relocate".  Bath fitters and companies that reglaze tubs and regrout walls will only prolong the enevitable.  Put your dollars to work by giving yourself a bathroom you can enjoy and that will help sell your home when the time comes.
