Concrete basement floor. Rough plumbing for toilet done 20 or so years ago by others. Concrete floor to get 12" x 12" ceramic tile. Floor slopes approximately 1/8" in 12 inches, left to right, as one sits on the toilet.
What is the best way to lay level tile under the toilet? Grout bed? Plastic shims? After tile is laid level under the toilet, the remaining tile will have to catch up with the sloping concrete slab.
In summary: Sloping floor, want level toilet.
Thanks for all suggestions.
If this room is typical bathroom 5x5, this would be quite affordable to
do the entire room:
Make sure you have enough and mix enough to do the entire space at once.
Custom and Maepi specialize in tile setting materials.
Don't know about toilets, but we had a couple of levelling issues when
we had tile installed....getting dining room tile even with terazzo of
kitchen at the doorway.....tile contractor explained to us beforehand
that adding extra mortar would do the job. There is a variation of
about 1/4" or 3/8" sloped so gradually it can't be seen, even when
looking for it.
1. lay tile
2. install toilet, shim to level with 3 small shims
3. mortar in space under toilet base rim
4. when mortar is set in a day or two, pull shims and fill holes with mortar
If you are concerned abou the mortar preventing removal in the future,
either use some sort of release agent on the base or use putty instead of
mortar. If you use putty, leave the shims in place.

If you're not concerned about the slope on the floor and only want the
toilet to be level, then use "Toilet Shims" available from any home
store. They cost about $.25/each and are slid under the rim of the
lower point(s) of the toilet. Cheap/easy/work like a charm. If done
correctly they're not that noticeable.

You can adjust for that while you are tiling around the toilet area. Just
use a little bit of extra thinset under the tiles at the toilet to the low
side. I always place the toilet on the tiles right after I set them in pla
ce. You can put a level on the toilet then if you want it to be perfect.
Then before the thinset sets I carefully sit on the toilet to even out the
tiles under it. Just leave the toilet there while you do the rest of the r
oom. That eliminates that occasional unevenness of the tiles under the toi
That the rest of the floor slightly slopes will never be noticed in that sm
all a space.
You didn't say what type of tile.
Follow the floor if you did not decide to use self leveling concrete.
Then mount the toilet on a plaster of paris mix, and use that to level
put sealer around the plaster of paris when done.
Don't forget to put your wax in b4 the toilet goes down.
I used that method years ago, the plumbing supply told me this is the
way it's done.
