Spacers essential for tiling?

[Kill_Phil]

Tiling the front porch using some victorian tiles.

The pictures online butt up the tiles and I've seen one installation where they also don't use spacers.

Using spacers (so bigger gap for grout) will ruin flow of the solid border so I guess the question is grout essential?

Found some 1mm spaces which may help...

I have never ever seen tiling without grout, make of that what you will.

If this was to see any water at all I'd suggest the grout ensures water tightness.

Yeah likewise, will just go with the 1mm spacers
