Designing Kitchens and Bathrooms - toilet mounting - new porcelain floor

Can anyone provide some tips here ?
New floor was just installed, and I saw somewhere where the proper technique is to mount the toilet (after securing the drain) up on wedges / shims about 1/4 to 1/2" off the floor and then to stuff the gap with the same grout as was used for the floor.
Is this a good technique ? or is there a newer way of mounting using caulk ?
The above technique requires 2 separate applications of grout....as the wedge areas unfilled by the first grouting must then be filled in the second application....seems like a lot of work. But I think it'll look good.
Comments ?

Your toilet should NOT be up on shims. The only reason for toilet shim use is if the floor is not level. I have grouted toilets that sit on the floor evenly. I just pushed the grout in and smoothed it off. Personal note: I would leave the back end of the toilet open (no grout or caulk) due to the fact that if there is a leak, you will know it faster. Not many people crawl around under the back of toilets so it should not be noticed. Good luck.

and I will take that good advice. I'll only use the shims should there be a leveling situation.
