A lot of Youtube videos is showing subway tiles being installed without spacers... Do you really need spacers or not for Subway tiles (Bathtub surround tiling) ??

Thank you



4-1/4" and some larger wall tiles have bumps cast in that act as spacers. Unless you want a larger gap, no additional spacers are needed.

Whether your particular tile has them is uncertain. They're often necessary to prevent sagging with heavier tile while the mortar or mastic sets.

  • +1 To rephrase, if the tile being used doesn't have bumps cast into them, or you want a larger grout space than what the bumps provide, you'll need to use spacers. – BMitch Mar 17 '16 at 20:40
