Designing Kitchens and Bathrooms - Installing ceramic tile in bathroom

I am considering installing ceramic tile in one of my bathrooms. It currently has vinyl flooring. Should I have any problems re-attaching the toilet to the floor due to the added thickness from the tile and backerboard?

Thanks!!

they make flange extensions if you need it

I've got a similiar situation, but I've got old hexagon tile that we can't get out, so we thought about
putting the backerboard and new ceramic tile over that.
We've got a claw foot tub, so we have to get extensions for the drain and water supply pipes as well
as the toilet.

Any suggestions?

when you say the tile can't come out - what do you mean?

It was installed when the building was built about 100 years ago.
We tried chiseling, won't even crack the tile. The mortar appears
to be some sort of cement mixture.

Someone who was in the same situation said we would have
to sledgehammer the floor out and rebuild it - which is not an
option for us.

To get most bathroom tile jobs out it is normal to have to take a sledge to it. it is normal to have a mud job (cement) and then lay tile on it. it is really not hard to take out. I say this because you will create height problems the other way plus how are you going to attach the CBU to the floor?

I agree with taking out all the old tile before beginning a new floor. We too had the old, small tiles over a thick mortar bed in a small 3/4 bath that needed a remodel. I used a small sledge hammer and cold chisel to break up the tile and the mortar bed underneath. Once you get going, it breaks up pretty easily. This is the only way to go. You can then check the condition of the subfloor to see if it needs any repair and reinforce it as necessary before attaching the concrete backerboard and setting the new tile.

Good luck and have fun!

I am remodeling our 50 year bath and kept the floor in place. Wouldn't you want to maintain the current tile mortar bed if it is solid already? I plan to tile over the existing tile file and live with the 1/4" to 1/2" height change, the only height issue with mine is the threshold from the hallway. Isn't tiling over existing ok? (in most cases)

In my opinion the cost to remove the old tile and mortor bed ($0- if you do it yourself) and put in a new mud job ($20 if you do it yourself, maybe 100 for a pro) and retile far outwieghs taking a shortcut method of tiling over existing - but you are correct some people do it. I just don't recommend it
