Spacing - large format travertine

[lockers]

Just about to do my bathroom but before I start I just wanted to get an idea of opinions on the ideal spacing for large format 600x40x12mm travertine.

Apart from obviously wanting it to look good I am planning to use Ivory BAL Superflex and want to know whether the wide joint stuff will be the best option or just the narrow joint grout

Also, any advice on whether or not to use spacers?

Thanks in advance.......

Yes mate deffo use spacers..use a 3mm this tight enough..you can use wide joint grout if you want but you will find it hard to spread it into the joints..so the standard super flex will be fine as this does up to a 5mm joint any wider then you will have to switch to wide joint...hope this helps.....

Cheers for the advice.

2 or 3mm is fine

i always use flexi as a matter of course - this is because I use Mapei - all their grout is flexible anyway, most suitable for wide or narrow joints
