Showerthought: my dad's 1998 tile job in Tucson is still perfect and my 2 year old grout is crumbling
My dad redid his guest bathroom in Tucson back in 1998 with basic 4x4 white tiles and it has zero cracks or loose grout to this day. I used the same style tile in my place two years ago but went with a premixed grout from a big box store and it is already cracking along the tub edge. What grout are you all using that actually holds up next to a shower?
