Perhaps it seems self-evident that the tile patterns you select need to be balanced when installed. And, yet, simply based on photos readily available, balance and common sense don't always go hand-in-hand.
Especially when your tile choices come in so many more sizes, shapes, patterns, and colors than in the past. Along with this availability comes creativity with endless possibilities.
Today we will focus on one of these options – the pattern. Combining these tiles, whether square or rectangular, with an offset pattern creates a unique visual many times not realized in is square or stacked design.
Note: Before you go further, please be warned. The images you're about to see may disturb you.
Tile Patterns Recap
Let's recap the ANSI Standards best practices related to tile patterns.
When you use an offset pattern, it is best to follow the American National Standards Institute (ANSI) guidelines. ANSI A108.02 section 18.104.22.168 states,
“For running bond/brick joint and any offset pattern (i.e. non-continuous grout joints) utilizing tiles (square and/or rectangular) where the side being offset is greater than 15 in. (nominal dimension), the offset pattern will be a maximum of 33% unless otherwise specified by the tile manufacturer. If an offset greater than 33% is specified, specifier and owner must approve mock-up and lippage.”
The ANSI guidelines provide even more guidance to the installer. ANSI A108.02 section 4.3.1 states,
“Center and balance areas of tile, if possible.”
And ANSI A108.02 section 4.3.2 states,
“An excessive amount of cuts shall not be made. Usually, no cuts smaller than half size should be made. Make all cuts on the outer edges of the field.”
However, when offsetting the pattern by 33%, it can be challenging to provide equal cuts on each side of the wall being laid out and not have less than a half tile in the next course.
In this case, the one half tile or larger rule may need to be set aside. When this occurs, always obtain the owner’s approval on the pattern layout to be certain it meets their expectations.
Poorly Balanced Intersecting Wall Tile Patterns
The problem gets worse if two intersecting walls meet at the inside corner with each wall ending up with small cuts as seen in the photo above.
In tile industry slang terms, you have what is known as a sliver cut or rat tail.
These cuts look really bad to the unsuspecting consumer who views this installer error. He or she may not know what is wrong with the situation in the corner, but that consumer knows it doesn’t look good.
Sadly, the regrettable result is that when this same consumer next looks an appropriate product for a home or business remodel, you can be sure s/he will remember that unsightly installation and comment, “If that is the way tile looks, I don’t want it in my house.” If, and when this occurs, everyone in the tile industry loses.
Combining Tile Installation Expertise with Common Sense
There are a couple of other issues involved in this installation, suggesting that this installer isn't Qualified Labor:
- None of the grout joints are the same size.
- The corner is not plumb which causes the sliver cut to get smaller going from top to bottom.
- The inside corner is grouted rather than being a soft joint with 100% silicone sealant.
Now for the common sense part of this situation.
Had the installer shifted the layout just 3/4” on each wall, the rat tails would disappear and the consumer would have no reason not to select tile for the next project. This is a win-win for all involved. Right?
