No pencil trim that is a date idea I happen to like 12 x24 tile on the bathroom floor and the walls of the shower to keep to as few grout lines as possible I like porcealin tile ceramic can chip easily. IMO never textured tile in a shower either and certainly no pencil trim with a textured tile

@Patricia Colwell Consulting So you wouldn't put a pencil trim around a niche edge? The tile IS 12x24 for the walls (onyx collection for the shower pan) and why not a textured or ceramic tile in a shower?

Schluter is a much cleaner look. You can do it in metal or a color that closely matches the tile.

P McG, I am using an Onyx Collection base too. What is going on your studs to waterproof for the tile? What color base are you using? I am thinking about Snowswirl for my base in matte. Matte is more expensive than the gloss for some reason. I can get the shower panels for a little over $800.00 but I am still thinking about tile so I need to know how how you are waterproofing your shower. Thanks.

Patricia Colwell, what about pencil trim on an kitchen backsplash? Is that outdated too? On the bathroom floor, do you suggest a textured tile or a smooth, non-glossy tile? I like the idea of 12"x24" tiles.

@Peke green board then tile. premade niche boxes are being used for the niches then tiled.

pMcG absolutely no green board in the shower. Who is doing this?? (unless you're doing a Kerdi membrane or Schluter Waterproofing system) But if you're doing green board, and then straight tiling on that , it's a NONO in the shower

Green board is a 100% no even with a board waterproofing system over the the top. Regular drywall is the only drywall allowed under those systems.

I was thinking concrete board??? But, I don't know what else should be used or in which order from the studs outward. I need to find a contractor who says and does the right process. I don't know what the process is though from the studs outward. I know where to start the concrete board according to the directions of the shower base.

peke, cement board is fine. you have a choice of vapor barrier. before cement board goes up, you do a plastic (or tar paper) vapor barrier over the studs then your Cementboard. (if it's an exterior wall, you'll have to do proper insulation before anything else)

If you do this you do NOT waterproof the cement board. Tape the joints (2" high alkali resistant, glass fiber tape), mortar them and all the proper fasteners. (corrosion resistant wafer head screws. NOT drywall screws)

read this on how to position the CBU

The other option is to not do a vapor barrier behind, and do Redgard over the cement board.

You don't do both because you'll create a mold sandwich. Mkay?

the other option is to find an old-school tile guy who muds. (wire lath and mortar) This way you'll get perfectly straight / plumb walls to tile on.

never put green board in a wet area. never.

No mold sandwiches for me. I have read the link, and many more on John Bridge.com. I guess Redguard is "painted" on or is it something else?

Thanks, Beth H.

its a painted on waterproofing membrane

Thank you.

I stand corrected because I don't know what I'm talking about, sorry. Greenboard is on the wall near the free standing tub. It is not in the shower. We are only using onyx collection for the shower pan, the walls will be tiled and a glass door.

Thanks.

So, can we see a picture of the finished shower with the Idole Tear Grey Tile? I’m using it now and I’m having trouble choosing floor tile for the shower. Thanks!

With this tile what color did you pick for the other walls? I was trying to go for light gray, but now I think I might just go with a white and there’s so many whites!

I’m just now using this tile for shower and having the same edging question. Could you post a pic of what you did with your edge? Would greatly appreciate it! Thx!

I am using that tile (all white) as an accent wall in my shower but I dont know what floor tile to use? I dont want mosaic, I want a large single clean slab for no grout look but everything seems to look like concrete and I dont want a white floor with 3 teens
