Resurface versus retile a shower

[Kevin S.]

I've got a tile shower that is original to the house (so 1975) that really needs to be refreshed, the tile is not the best color and the groute is discolored or missing in places. I wanted to see what the BP community's take was on having the shower resurfaced versus having all the tile ripped out and replaced. Has anyone had experience with resurfacing? Was the cost truly a lot less than just replacing the tile and do you think it was worth it?
