You can tile over tile -The toilet is not an issue inso far as raising the floor. It's a $10.00 part at hd's plumbing section. flange.
I'll tell you what- there is lots of good flooring products you can go over tile with, Example 1. I used glueless sheet flooring on a apartment tile bathroom floor because the stuff was new on the market and I was curious ! The floor was old fifties tile ugly as hell.Let me tell you it looked great and stood the test of time. You can buy the double edge tape that comes with the product or just glue the edge at the bath tub and door . It lays there flat as a pancake stays flat too.
There is that snap together stuff looks like immitation wood they make it in immitation tile-too- that would go. You might fill the impressions with a putty knife. You can buy a box of u mix it powder-grout where you get the tile.
Pergo was originally invented in Europe-Sweden if I recall ,for kitchens and baths- people in europe go for the hard wood and kitchens and baths were usually the only rooms lacking hard wood.. hence pergo was invented. Than it took off as the in thing to do to european apartments-people had their entire apartments done in pergo and when they moved they took or take their floors with them !
I've used 12 " by 12 " square vinyl tiles over tile-filled in the grout line impressions -looked great. Somewhat timely though leveling the tile grout lines. (telephone )
All in all it turned out good. I used self stick vinyl 12" by 12" squares, but I also used a small can of multi purpose glue. It looked just fine. Great said the owner of the apartment building- considering what it will have cost for me to break tile out -concrete floor and install new tile.
There is a lot of products out there you can go over your tile floor with. Quick to install and not too spendy.
You need somebody that knows how to do things to help you. You know any realtors that might have a line into guys the labor type with some skills ? Like somebody you can keep around at a price that won't break the bank who can help you sort through it all ?I call them helpers.
