A couple more thoughts that may sell her on the vessel sink. The theme of this trailers decor is rustic natural materiel’s and gloss black shiny appliances and things like outlet covers and switch plates. The dinette table is a piece of 1 1/4" blued pine live edge slab. I have ripped it lengthwise and will make an epoxy river table that will have natural river stone in the river pour with just clear epoxy. For the area above the counter the walls will be tiled with those tile sheets that have multiple “rocks” on them. Before you say anything. . .yes i am worried about the flexing cracking the grout. I found a grout product that is a sanded latex grout. I am hoping this will have some flex and give. This may end up being a disaster only time will tell. I am not sure any tile will stand up to as much movement as I fear the walls of an old trailer will have. In addition to this we are making all the drawer pulls from scratch using native river stones like the one I will use in the table. Plan to drill a hole in them and epoxy a piece of all thread into it and then a nut on the back side.
I say all of this because I have a couple thoughts now on a type of vessel that may intrigue her. One is to get a piece of blued pine in the round and turn a vessel and then epoxy clear coat it. While that may look cool I ma not sure that would be a good route to go labor intensive and then getting scratched. Since we are doing a polished/glossy black appliances getting a stainless or aluminum bowl and having it powder coated black could be cool. And the final idea would be to manufactured vessel sink that looked like stone such as something like this.
maybe some of these ideas will peak her curiosity.
