Tile over Tile?

Redoing our downstairs bathroom and pulled up some fake wood flooring to find what looks like a 1960's tile job. Can I lay down cement board and lay new tile over the old? It's a pier and beam house. There is also some weird cement repair job on the close left hand side. I'm guessing they need to level that area to install the fake wood. Oh yeah, Wife wants hexagon mosaic tile if that matters.

If you don't own one, I would rent an electric chipping hammer and bust it all out.

Removing what's there is probably the better choice, but if you did want to tile over what's there, you'd first need to clean off those tile much better. Then, you'd want to examine them to see if there are any cracks. If there are none, and you can accept the increase in height with a new layer, you cannot install a cement board, but you should probably install a primer specifically designed for tiling, then you can add the thinset and new tile on top of it. You'll also want to check to see how flat the existing tile is, as if it's wavy or uneven, do not expect to flatten things with thinset, it should be done with different materials.

If there are any areas without tile that are going to be tiled, there are patching materials that can be used to fill in, depending on what is below.

So pretty much the same amount of work either way I go but removing the old tile I might have a better outcome. If I do remove the current tile I will have to lower the baseboards or get taller ones to make up for larger gap at the floor level.

It'll be more work to remove the tile and build back up but you likely would end up with a better job. The height change would have to be dealt with at the doorway and with the toilet flange.

Is the tile already higher than the outside floor? Looks like you might have quarter round tiles across the doorway. A picture of that might be helpful.

The bathroom is about 6in taller then the floor so it's a step up to get in.

Odd, any idea why? Older house with a newer addition?

I think it was a closet converted to a bathroom. It's under the stairs. I don't know why it's raised. Only reason I would think it's raised is for plumbing reasons so I crawled under the house to verify. Nope, plumbing runs close to the ground. I almost want to lower.

I purchased a hammer drill yesterday from harbor freight. Today I'll start removing the old tile.

Ok, from odd to super weird.

There must be something under that, as I can't fathom a different reason why someone would raise the floor.

Looks like you'll find out soon!

i tiled my dining room over the existing tiles i laid about 10 years previously, removal of the tiles would have resulted in destroying about a $1000 worth of undertile heating, i ran a grinder over the tiles to remove the surface glaze and primed the floor with mapei prim grip and tiled over it with 1.2 x .6 tiles, there was also a step up into the room so the height difference didnt matter

Could be a mud bed, Michael, but I bet it isn't 6" worth of mud bed. Given the 6" height I'd guess it's 2X4 framing, plywood on top, then mud.

I'd simply have to get to the bottom of it, the 6" step up would be a no-go for me. At the very least I'd have to know why it's there. If it can come out I understand doing so creates even more work, like replacing the drywall and door trim, which wasn't in your original plan, but that's remodeling.

IMO, natch.

I was thinking about putting up wainscoting so walls shouldn't be an issue. Guess ill work on figuring out how thick this bed is and why its raised.

Mud bed out!! it was only about 2" thick so not too bad. I don't think I'm going to be able to lower the floor due to the sink drain and it might be too much work either way. Should I go back to another mud bed or plywood and cement board?

Are those planks T&G, if not, you might as well tear them out, too. That would give you access to the plumbing and might give you some options on how to relocate it so it won't require the floor to be raised. New tile over those planks, at the minimum, would require a layer of plywood, then your choice of tiling interface, something like Ditra or a cement board.

You don't want to leave galvanized drain pipes in there (at least that's what it looks like). Especially on an older home, the insides are almost certainly rusting. Do you know if the sink is properly vented? A house that age is more likely to have an S-trap, which, should you be getting this inspected, would not pass.
