Our recommendation for tile in a shower based on the size of 6' x 3'5" would
be 12 x12 or larger. I would not hesitate to use a tile as large as 12 x
24. These tiles are usually laid either on a stagger (or brick) pattern for
a traditional or transitional look or for a more modern look with tiles laid
vertical or horizontal stack. This shower is large enough even though the
side walls are smaller. This would give you a very cutting edge look. The
larger tile offers a more open feel and less grout lines. The floor of the
shower I would recommend 4x4 or smaller.
