Is porcelain more durable than ceramic?

If any odor/urine lingers in surfaces, any coating/painting/repairing work you do may only mask the odor ...temporarily.I'v already replaced all flooring with porcelain tile ( on slab that was probably not cleaned good enough), Kilz ceilings and wall surfaces, replaced windows and all base boards and odor still lingers. 

Also, I'll tag a few more from this thread so everyone knows that we're meeting up on Tuesday, April 23rd at 7:00 PM at the Gather Bar at Galvanize 1062 Delaware Street, Denver, CO 80204 from 7pm - 9pmMichael Begley Robert Blake Val Dufour Tanya H Scott Limoges Ryan Nguyen Jason Nickel Grant P.

SteelI want something that is going to last awhile, but not forever; as I will eventually have to update.2 Kitchen: Porcelain Tile vs Vinyl I like the idea of tile, but I feel like with a rental unit, the upkeep might be difficult.

This is what I have so far:Lets say I replace all of the rooms and living room w/ 10mm laminate from lowes at $1.79/SQFT at $0.99 install (I could do this myself or my wife could easily if we get a weekend during the rehab) Total = ~900*$2.78 = $2511Kitchen and baths w/ tile at about $2.40 and $0.80 install is what they quoted me for my porcelain wood tile my my house so Total = ~220-250 =  235*$3.10 = $730Floors Total = ~$3300 plus maybe $200 in prep?

Obviously the porcelain finish on a new tub is more durable(at least they used to be) than fiberglass, but keeping the caulk and grout looking good has been a chore.What about the hybrid setup steel/porcelain tub, with fiberglass panels surrounding?

Katherine:  Did you say this was an enamel/porcelain tub?
