Toilet installation advice

Getting ready to install my first toilet! Would appreciate some advice.

Doe's it appear as if I should do anything else before I install the new one?

Does the flange appear ok?

Should I do anything about the space between the tile and the flange? Fill it with something?

Thanks in advance!

Don't forget to remove the rag. You wouldn't be the first.

I would probably tweak the flange closer to level.

I don't see anything holding the flange in place. Ideally the flange should be mounted on top of the finished floor with screws going through the flange, the finished floor, the sub-floor and into substantial blocking under the sub-floor. Otherwise there is nothing really holding the toilet to the floor and the pipe can move around, eventually breaking or at least causing a leak.

If this is on a slab then filling the space between the tiles and the flange, along with under the flange with mortar or concrete topping mix will help. Install screws through the flange and into the concrete while it is still soft or use Tapcon (R) screws after it is hardened.

Don't forget to remove the rag before setting the toilet.

Agree with above comments. If possible try to make flange even with floor surface. But it's not critical. Flange must be secured to the floor with bolts. Filling in the gaps with grout will make for a cleaner install but should not affect the seal. When you mount the toilet to flange I suggest you do not caulk around the base. Some may disagree but if you have a leak you will want to see it. Caulking will hide it.

I think it looks better if caulked but leaving the backside open won't trap the water ... and it's harder to caulk the backside anyway
