So it sounds like you want to use a wood-look porcelain tile as your flooring choice. And that you want the tile to help make the space look bigger which is why you are choosing a form of herring bone installation. You are trying to decide between a herring bone or a chevron pattern herring bone where the tiles meet at a 45 deg angle (cut at the top and bottom of each tile) like a mitered corner.

OK...now that we've go that straight, here's a few things you will want to consider. To achieve a herring bone (no cuts to the tiles...they remain intact) you MUST use a tile that is a perfect multiple of itself. That is to say, the LONG edge is TWICE or Three times as long as the short edge. So a 12" x 24" tile will work. A 6" x 18" will work as well (these are rare but are out there). An 8" x 36" will NOT work.

That means your purchase/product choice will be limited by the pattern you wish to use. With wood-look tiles this normally isn't an issue....but it is still something you MUST consider.

The second thing you will need to know about "chevron" pattern is: it works for wood but it is HORRIBLE to work with wood-look tiles. Normally these tiles come in RECTANGLE shapes. It is *possible you might find a tile that is specifically designed in the shape you need it to be to make the chevron work. This would require INCREDIBLE LUCK and a high price tag (special shapes have special pricing). And then you would be stuck using the same pattern for the entire floor - every room would have to be a chevron pattern. There would be no way to change that with this particular shape of tile. And cutting them to shape would be a nightmare! The amount of waste you would have due to chipped tiles would almost double your purchase.

Thirdly the cost to install herring bone (I'm just going to assume this is how you will work because the chevron is very hard to get to work in tiles) is pretty high. And the waste level for herring bone is another 10% - 15% more than a traditional/straight install.

It sounds like only some of your space will get the herring bone while the rest will get a straight install. That's a good way to maximize the appearance of the tiles while still keeping costs/waste at a moderate amount.

As for direction....I would let that wait until you find the tile that will work in a herring bone. Then take it from there.

You just doubled your installation cost, and the capable installer pool was reduced by 9/10ths.
