Detailing for Water Management at Sink
I am looking for a detail for the kitchen counter extending onto interior window sill.
We are starting construction drawings for our house, and the design calls for the kitchen counter (e.g. behind the sink) to extend, at the same surface height, to the window frame.
Is water management a significant risk here — either for mold to grow on the caulking, or for water intrusion to the structure? If so, are there recommended construction details or best practices? (My family tends towards the “splashier” side when using a sink, and the lazier side for prompt cleaning.)
The counter will be quartz, the windows will be flangeless triple pane windows (one tilt-and-turn and one fixed), and the exterior wall will be 2×6 with 3″ of continuous insulation outside of the sheathing. The windows will be somewhere between “outie” and “in-betweenie” windows; i.e. about 3-5″ of window sill between the interior wall and the window frame. We can tolerate a visible seam in the quartz countertop at the transition to the sill.
