Need Help - Large Format Tile in Shower Floor
In desperate need of advice. I have planned a walk-in shower for ease of maintenance (no curb, no glass, no squeegee, no curtain). Part of the plan is to age-in-place, although we are both perfectly physical OK now, the curbless design will allow ease of entry if it is ever needed. We've bought/selected the tub, sinks, granite and vanity. along with gorgeous fixtures to include a rain head and hand held shower. The folks here on the forum have provided me with invaluable advice directly or indirectly with good design solutions.
So now we are ordering porcelain tile.....
I purposely ordered a linear drain so that I could use large-format tile and have ease of cleaning less grout. I have 3 inch tile now and hate it and the grout lines. I love all the large format look showers on Houzz. Every time we discuss tile, my contractor has argued for 2x2 mosaic tile in the floor of the shower. Then today the tile distributor practically insisted that we order the 2x2, almost stating it was a safety requirement. Then she backed off a little and said well it's really up to you - I had planned on about an 8 x 24 size but very willing to step it down to 4 x 12 or 8 x 12 on the floor (with 8 x 24 on the shower walls) if my hubby will feel more secure with more "grip" (closer grout lines).
So any advice/opinions/sympathy :-)? Opinions on scale of smaller tile in the shower floor to the walls? The tile we have picked out is Daltile Fabrique which has a little texture to it. We will have the unpolished on the bathroom floor also (12 x 24) and the unpolished seems to have a pretty good slip rating. I think after making all the other decisions up to now I'm too exhausted to think clearly on tile dimensions. Appreciate your help!!
