roca toilet leaking around the base?

I don't know about roca toilets in particular, but typically it would just be a wax seal. Shut off your water supply valve to the toilet, flush it to drain the tank, and loosen the nuts on the sides of your toilet. Remove the toilet and put a new wax seal with a poly-ethalyne sleeve on the toilet, lower it into place, and reconnect the bolts.
