Hi all. everyone is always so helpful. i have finally decided on two looks but don't know which to use in which of the two bathrooms I am using. One is the bathroom on the main floor (9x5), full bath, the other is the master bathroom (12x6) full bath. Both looks are variationsof terra cotta, beigy looking "fake" stone look. One design consists of 10x 13 (the 13 is the length)tiles for the wall, all the way up with a 9 inch listello, the other is 12x12 half way up and 6x6 the other half, with a listello in the middle and I may do the bottom half a slightly darker color than the top. The second design has mosaics that I might use for the tub area if I do it in the master bath, on the main floor it is a skirted tub so that wouldn't be necessary. Are there any rules of thumb as to sizes for diff size bathrooms or types of bathrooms?

Thanks
