Advice please on floor and wall tile spacing

I usually go for 2mm spacers, but check the grout you are planning to use as it may specify a minimum gap

 

2mm is very small.

I'm not at all saying it's wrong - it's a matter of taste - but the best thing I can suggest is to look at pictures of your tiles 'fitted' and see what they have.

Will the floor tiles have a contrasting grout line?

 

Either grey or black grout, white will get stinking before long and you'll regret using it.

 

If the edges of the tiles are rounded then the grout joint will look slightly bigger than the spacing; to give you an idea, here's a bathroom I did a couple of years ago using a 2.5mm spacer on 600x600 tiles (same tiles on the floor as on the walls)



:edit: Its a panoramic photo - the tiles are straight and level in real life, honest!

 

If your set on white grout for the floor, then look at 'epoxy grout'

Downsides -

More expensive
Limited working time
Harder to use
Harder to clean up
Generally more faff, especially if this is new to you

Benefits -

Very hard grout
Totally impervious
Won't stain
Doesn't harbour bacteria
No need to seal

Not often used in domestic setting, maybe for a tiled kitchen worktop (if anyone still has that 70s look)

Often used in industrial workplaces, professional kitchen, manufacturing plants

If using grey grout, probably not needed but white.......... won't stay white for long unfortunately

 

You can overcome this by sticking the spacer in endways ie. by using one of the four 'points' at 90º to the tile. Remove the spacers once the adhesive has set and reuse them again next time. There was a thread about this not too long ago.

 

This is the thread. Phil the Paver posted a picture showing what I mean in post #2.

Reusable,visible, hate the ones you can leave in the joints,they are are fiddly, sometimes hard to see if using a white tile.

Can't find much on youtube about them.

 

If you are wanting the grout lines on the wall and floor tiles to line up, double check the exact size of both tiles. I had someone in to do my tiling, the floor and wall tile sizes were different by, I think, 2mm and he should have use different spacing (e.g. 2mm and 4mm) and didn't.
