For a sink to be accessible in a corporate break room, it must comply with ADA standards, which include a maximum height of 34 inches (864 mm) above the finished floor, a clear floor space for approach, and knee space for wheelchair users. Additionally, exposed pipes must be insulated to prevent burns. Option A (integral solid surface sink at 34" H with a 30" x 48" front approach and insulated piping) meets all requirements: the height is correct, the front approach space is adequate, and the piping is insulated. Option B (undermount stainless steel sink with a side approach) has a 30" x 42" approach, which is too narrow for a side approach (ADA requires 30" x 48"), and a grab bar is not required for a sink. Option C (porcelain drop-in sink with exposed rim) may pose a barrier due to the rim, which can obstruct access for wheelchair users, despite meeting other criteria.
