when u say walnut are you saying real wood or veneer? i can't find the cathedrals like this in a walnut veneer that isn't yellowish vs this nice red or chocolate color seen here that can only be achieved w a stain or oiled look - please help! in bathrooms contracter says reallu shoulnt use real wood but i can't find a veneer with cathedrals that can be stained

We always use real wood when we can, and the cabinets are real walnut. We wouldn't recommend veneer against anything that's getting wet, you might consider western red cedar (the wood on the ceiling and wall_ or ipe (the wood we used for the deck) that is sealed, note again that these are all solid pieces. @Design MACs Can't remember the exact combo but our usual go-to is Benjamin Moore Arborcoat semi-transparent or fully transparent depending on need.

Is there a concrete platform under the teak?

@Inspired spaces. No, the tub is sitting on the floor and the ipe platform was built around it.

what exactly did you use on the ceiling I love it

The architect specified western red cedar
