For the floor in the kitchen area, I started with a piece of 3/4" thick plywood that measures about 4'x5'...

I decided to go with a vinyl tile with a self-adhesive backing instead of ceramic or stone...mostly because it's a lot lighter and won't chip or crack. 

The manufacturer's directions said it adheres better to plywood coated with a latex primer so I painted it white before laying down the tiles.

Went with a brick-like pattern...

A lot of the new vinyl tile is groutable which helps it do a pretty convincing job of impersonating stone and ceramic tiles.  This was the start of filling grout into all the seams.

This was the start of getting the bamboo flooring laid out.  It's not the most conventional approach but I decided to glue and nail the bamboo onto sheets of plywood to make two removeable floor panels for the living room area in the front of the bus. 

It was kind of like playing with giant bamboo puzzle pieces when I was trying to figure out how to lay them all down.

The darker bamboo is going to go in the living room area in the front and the lighter bamboo will be for the recording studio area in the back of the bus.

Bamboo grows really fast and makes for a great sustainable building material.  Some say it grows 24 inches in a day....quite a bit faster than the 50-150 years it can take for most hardwood trees to mature.  The manufacturing process could use a lot of improvements but bamboo is still a game changer in the effort to reduce clear cutting and massive deforestation.
