Grout gap for floor tiles

[Rolandk]

Hi,

I'm about to lay porcelain tiles (300mm x 600mm) in kitchen with electric UFH and on Marmox boards. On the box a minimum grout gap of 5mm is recommended but I'd prefer smaller if possible. Is that advisable or should I stick to the recommendation?

Thanks,

Roland

Cheers,
Roland
