Porcelain floor tiles in kitchen? Or natural wood?

[singersgirl]

We're looking at flooring for our new kitchen extension and considering large porcelain tiles (glossy or otherwise). DH is worried they'll be very slippy when wet. Those of you who have them, are they particularly slippy?

He likes the idea of wood throughout but I'm worried it will stain and wear easily.

We are going to have underfloor heating.

Any views?

After having tiles in our old kitchen we have put engineered oak in our new one. We thought about tiles again with underfloor heating but as the cost of energy is going to rocket so we decided to get wooden with lots of good quality insulation underneath to keep the fuel bills down. ( we are in chilly Scotland). Looks good and has been fine so far.
