Bathroom Tiling Questions, Please

Hello,

Looks like we will have to have our bathroom re-done.

Have the following questions, please.

a. Will be using the typical ceramic tile.
Is there a difference between ceramic Wall-Tile, and the ceramic Tile that would be used for the floor ? If so, what are they ?

b. The sub floor is pretty well rotted now also, and will have to be ripped up and replaced.

I guess it would be better to specify Ply-Wood rather than particle board.
True ?

What grade, quality level, or type of Plywood should we go with ?

What thickness ?

Anything else I should probably be asking you folks before getting a Contractor in for a quote ? What to specify, look out for, etc. ?

Much thanks; appreciate the help,
Bob

Bob,

Any tile can be used on the walls. The only possible limitation would be the possible lack of matching trims or thickness or weight. Most of these can be worked around though.

You don't want regular soft bisque ceramic tiles on the floor. Where will you be shopping for the tiles? Please hire a "real" tilesetter and let him get and be responsible for the tiles through the distributor.

After the old tile & underlayment/subfloor is gone you want a subfloor that is rated as "subfloor" which means exterior glued plies and tongue & groove. But let us know how far you have to go, (rip) since you may have 2 or more layers and not all may need replacing.

Particle board is NEVER allowed in a floor system, it's either plywood or OSB. Hopefully OSB is what you meant.

Interview 2-3 "real" licensed tile guys and take good notes of every steps and method they propose. There are many methods and not all good. Get all info in writing.

From OP: Followup. OSB ?

Hi,

Much thanks for info.
Appreciate it very much.

Not clear on this:

What's "better" for the floor under the tile:
Plywood, or the OSB Board mentioned ? Why ?

What's a good thickness ?

Thanks again,
Bob

Some of us prefer a plywood subfloor, other like OSB such as Advantech. You want 3/4" min. Be sure it's installed properly. Both need to be gapped between sheets for one thing.

BTW, the subfloor is what you see when you look up from under the floor. Were you looking up or down from the room? Are they the same piece?

You will not have tiles directly over the subfloor of course. You may have another layer of ply, then the tile backer or membrane such as Ditra.

But we don't know how you floor is built. Tell us the; size of the joists, their species and grade, the spacing and the span.
