We recommend a 3 16 grout size for our ceramic tile line.
Medium size tile bond pattern shower wall tile grout sizing.
Although 1 16 of an inch may seem unimportant for example on a 12 tile it represents a 50 variation in a grout joint 1 8 inch wide.
For tile having a total variation of 1 6 inch in facial dimensions a minimum of 3 16 inch grout joint shall be used.
This is a twist on the basic offset pattern where each tile s edge is only offset by one third of the width of the tile above or below.
Finished grout lines will vary from 1 16 to 3 16.
Tile size percent a 6 x24 100 running bond brick.
It creates strong diagonal lines in the pattern and is often used instead of the basic offset pattern with larger tiles to hide imperfections like in this danish home from nordic design.
Tile patterns one size pattern tile size percent a 4.
Note that using the smallest grout possible will increase installation time.
For example if the edge warping of a rectified tile is 1 32 the minimum grout joint is 1 8 1 32 5 32.
Tcna recommends a minimum 1 8 grout joint for rectified tile and minimum 3 16 grout joint for calibrated tile.
For shower walls generally it is best to use larger tiles from 4 inch by 4 inch tiles on upward to large format tiles in the 15 inch by 30 inch range.
Actual finished grout spaces will vary from 1 8 to 1 4 if 3 16 spacers are used.
If smaller spacers like 1 8 are used it will accentuate the size difference of handmade tile.
They also suggest adding to this width the amount of edge warping on the longest edge.
Though if you re tiling a closet sized shower a medium size tile such as 4 x 8 and 6 x 8 could work better for the floor larger tiles square hexagon or rectangular with tighter and fewer grout lines can similarly make a room seem more open.
This thickness leaves room for the natural variation in size and the perfectly imperfect edges of handmade tile.
Especially in a small shower a larger white tile can make it feel less cramped.
Nominal centerline of all joints shall be straight with due allowances for hand molded or rustic tiles.
Medium sized grout line widths 1 8 to 1 4 inch require the use of sanded grout and are typically featured when moderate size variation occurs among the tiles or when tiles with lugs are used.
From a visual standpoint tile smaller than 4 inches square creates a busy appearance.
