A friend at Co-Op Fabrication in Kingston, New York, custom-designed the kitchen island and cabinets. Tiffany Jen swapped out the dated vinyl floor for matte white tiles from Home Depot. The backsplash is matte white subway tile from Tilezz, and the plywood cabinets are topped with white quartz counters. The Ready Stacking Barstools from Blu Dot slide under the island counter.
