I finished installing the floor yesterday evening. It took me two half days to lay the 217 sq. ft. It was a pretty easy process with the click lock system that Cali Bamboo uses on this style floor. It was a huge benefit that the click lock works both ways, too, though it's certainly easier working on one side.
After the old tile and underlayment were gone, I stapled down a new layer of 1/4" plywood underlayment, than layed down Cali's foam membrane and taped the seams. I always have trouble deciding where best to start with the flooring. In the end, I laid the first plank so it would end on the lip of my cellar stairway. That gave me a full piece there and about half a piece on the opposite wall. Fortunately, that stairway was as close to 90° to the sliding patio door across the room as possible, so no trimming was required for the first piece. I worked from there towards the cabinets you see in the photo below, and then the other way towards the dining room. Had the flooring not been able to interlock in both directions that would not have been possible and it would have been a more difficult process.
Here's when it was about half done. I left a 1/2" gap around all the walls and cabinets.
I ran the flooring into the half bath you can just see in this photo, too. The flooring ended up a millimeter or two higher than my old floor and the door to the garage at the top of the picture had to be cut off to clear it. So that took a half hour; oh well. Because of the increased height I also had to cut off all the door trim so the flooring could slide underneath. I did that w/o trouble using a pull saw and a piece of scrap as a spacer.
And from the dining room after it was all done.
I had to sort out at least 10% of the planks due to small defects on one end. One had a damaged edge. I was able to use all those pieces along the way by trimming off those ends where they best fit the layout and could end against a wall. The visible joints you see interlock on the ends so you can't cut off a defective end and still be able to use it against a mating piece. I ordered an extra box when I bought the flooring. When I was done, I had 4 full length planks left over as well as 3 or 4 sizable partials.
The Cali Bamboo floating flooring was pretty easy to install. It looks good, though we're still getting used to gray after the much lighter tile we had before. This is just step one of the kitchen upgrade. Later this year I plan to replace all the cabinet doors and drawer fronts with new ones with a much different color scheme. That will be the subject for another day.
