KRAUS Standart Pro 30 Inundermount Single Bowl
The KRAUS Standart Pro 30 offers a heavy-duty 16-gauge stainless steel construction with a single full-sized bowl.

Buying Guide: Key Purchase Considerations for 30-Inch Deep Sinks
- Sink type and configuration
- Single-bowl vs. double-bowl: Single bowls offer maximum basin space for large pots, while double bowls improve multitasking for washing and prep.
- Workstation features: Integrated ledges, cutting boards, colanders, and roll-up racks increase counter efficiency by enabling over-sink tasks.
- Material and gauge
- 18, 16, or 11 gauge stainless steel affects noise, durability, and resistance to dents. Heavier gauges are quieter and more durable but may come at a higher price.
- Finish: Brushed or satin finishes reduce visible fingerprints and smudges; nano-PVD finishes offer added scratch resistance in some models.
- Installation and cabinet size
- Exterior dimensions of 30″ L x 18″ W typically require a minimum cabinet width around 33″ or more. Check the cutout template and ensure countertop clearance for edge profiles.
- Under-mount installation provides a seamless transition to counters but may demand precise cutouts and professional mounting.
- Drainage and bottom design
- X-shaped grooves and sloped bottoms improve drainage, reducing standing water and improving cleaning efficiency.
- Rounded corners (R10 radius) ease cleaning and help prevent food buildup in corners.
- Accessories and inclusions
- Consider whether the kit includes a bottom grid, drain assembly, mounting hardware, and countertop templates. Workstation options with cutting boards, dish racks, and colanders add value for busy kitchens.
- Overflow options can prevent spills in sinks prone to heavy use.
- Maintenance and durability
- Stainless steel resistance to rust, staining, and corrosion is key for longevity in high-use kitchens. Look for protective coatings or mechanical dampening to reduce noise during dishwashing.
