Hi,

We have a small bath off our mudroom. We just use the same identical tile (12 inches square). The transition at the door between mudroom and bathroom is seamless, just keep laying the tile as per normal.

Turned out OK for us.

Best, Mike.

Friend of mine has a 5' x 5' powder-room tiled with 16" tile laid on a diagonal. It looks terrific. Somehow the large tile actually makes her powder-room seem larger. Maybe it's because there are fewer grout lines so it is less "busy" looking.

Our back hall and powder room are the same 13-inch 'limestone-look' porcelain tile. Setting tile on the diagonal does visually 'stretch' a room. I didn't do it there because I wanted it to look more Old World.

My 16 inch tiles continue right into my powder room (5 ft x 5 ft). Looks great.

You don't need smaller tiles just because the room is smaller. Keeping the same size looks better and works better too; you don't have to worry about a transition. I think transitioning to a smaller tile would look jarring where the 2 tiles meet. Keep it all the same size and same tile for a clean, continuous look.

Ditto.

We have 12" slate tiles that run from the mudroom straight into the bath. I love it because the slate is roughed enough to handle all the dirt yet elegant enough for me to use that bath as an nice powder room for parties.

Thanks, everyone! So, that's unanimous for continuing with the larger tiles...makes sense. I was basing my "smaller tile" theory on something that I had read about using smaller tiles for better traction in the bath because you have more grout, but maybe I had it confused with shower tile. Using the same tile simplifies my decision-making. Now, I just have to decide WHICH tile!

A powder-room floor isn't very likely to be wet (well, one hopes not anyway!) so slipping shouldn't be much of a worry. If you're concerned, you can choose tiles that have a higher "coefficient of friction."

Coefficient of Friction is a measure of slipperyness and ranges (in theory) from 0 to 1. Zero would mean no friction at all while 1 would be mean you couldn't slide against the surface at all no matter how hard you tried. For comparison, rubber tires on dry road surfaces experience a COF of about 0.7 to 0.8 but when the roads are wet the COF drops to around 0.4. Wet ice can have a COF of 0.1 or even lower.

For a shower floor, I would look for a tile with a wet COF of at least 0.6 or else use 1x1 or 2x2 mosaic tiles so that the COF of grout is more important than the COF of the tiles. Even with 1x1 mosaics though, if the tile is very slippery, you can wind up with a very slippery shower floor.
