How are the rest of the windows in your home trimmed? Do that. Or, since you like the style in the photos, do that. By the way, the correct term for the piece you’re talking about is stool, not sill. ;)

This window cannot be trimmed the same as the other window in the room as it is a completely different type of window. And all trim on the other doors and windows will be replaced but not yet.

felizlady , that is certainly on the list of possibilities but I may need two switches under the window and though that would look weird.

I believe that an outlet in the cabinet under your sink, which is needed for the garbage disposal and possibly your dishwasher, would cover the code issue. I have never seen an outlet directly over a sink for the obvious... water and electricity don't mix. Have your electrician check. This situation makes little sense.

It does not. The outlet must be above the countertop.

Will a button switch for the disposal near the faucet suffice or does it have to be an outlet. The only other option I can think of, is to have the outlet placed horizontally in the tile. It will have to be a GFCI outlet.

It can be a button switch for the disposal.

Does anyone have a thought on another way to frame the window?

The photo you posted looks nice or you could make the sill a bit deeper. Enjoy your new kitchen.

I was going to pipe up with "just make them horizontal and you're safe," but it sounds like you'd like to make the vertical if you can.

Here are a couple options to throw into the mix, with how I've trimmed out windows to meet space constraints.

I would make them horizontal. And do ask your local inspector if the 4' requirement still to counter runs with a sink. In my jurisdiction, the 4' rule excludes (i.e., a sink next to a 4' run of counter would only need 1 outlet above that counter).

salex, already have asked that question and the answer is yes.

My window is trimmed out like your example pic (matching countertop material, dog eared at the front, wood frame around the window). I like it.

For outlets, have you considered if something like this from LeGrand Adorne would work? They have a different look than standard switches, and might be more visually appealing. Or not ;) I used them at the end of my island because they offered a color that blended well with my cabinets. I have used their switches in our family room as well, they have one that is a prox sensor.

My window seal is the same as the counters. I wouldn't have it any other way.

Here is how I trimmed out my window using my granite as a backsplash. Not sure if this helps in your application. I have outlets on both sides of the windows and a button next to my sink for my disposal. The outlet for the disposal is underneath my sink.

I would look into using Sillites in your window sill. I used one on the end of my island.

We have a triple window and our electrician told us that the sink is considered a disruption in the countertop so the rule in our jurisdiction is that the outlets need to be within 24" of the edge of the sink. We used plug mold under the cabinets that are on either side of the window.
