We've been annoyed with washing pots & pans in double basin sinks for years. I couldn't fit a pan (with handle) flat on the bottom to scrub (or soak if needed). The sink was shallow (as deep at my hand) and with pans at an angle, the water tended to hit in just the perfect way for me to get splashed. The silicone sealant of the undermounted sink was nasty when we moved in from the previous owner's probably dealing with the same splash back issues.I measured the hole in our granite countertop and then researched online sinks that would fit into our existing hole. Many manufacturers are vague about hole size requirements because a "cardboard template is included". Templates are great for new installation but not replacements. Anyway, the detailed dimensions of this sink made me believe it would fit. Plus, this sink comes with the steel bottom rack, colander, cutting board and folding dish rack. Competitors often include just two of those accessories, not all. I was off by about 1/8" because of the placement of the internal clip brackets vs the curved corners of my hole. Each bracket has extra metal to each side of the hole that is larger than 1/8". I'm including a picture to show the location of the four corner brackets that were problematic for us. Minor adjusts with a Dremil are far easier than major cuts so we made it work. Within a few hours, the old sink was out & new sink was in. After filling up with water & waiting for sealant to dry & retighten clips, we could finally use the sink! (Tip: plan ahead for meals so you won't need the sink to clean up)Within the first day of use, here are things I noticed:1) Colander: when I came in from the garden with produce, I was able to dump it in the colander and wash right away. How convenient!2) Dish drying rack: We won't use this to dry dishes as we have an over-the-sink drying rack. However, my husband used this folding rack to support thawing meat.3) Bottom sink rack: I wasn't sure if I wanted this because I'm sure it will get messy any gross over time, but it's great! My daughter made a smoothie and put the blended top in the sink to soak. It didn't fall over! The bottom of the sink isn't level for water drainage purposes, but this rack is level. The blender full of water didn't tip over! I washed out our rice cooker and when I poured out the pot full of rice bits, the water draining didn't knock over the blender, and little bit of rice didn't get caught behind other things in the sink. This was profound. Like it really changed my perception of how things work.4) Decorative drain cover: we have a garbage disposal but I can still use the decorative drain cover. This cover eases my concerns about dropping a fork down the disposal. Thank you.5) cutting board. I don't have a lot of counter space to work so it's really nice to be able to cut over the sink area.6) Depth: this sink is at least 3" deeper than the old sink. This makes a huge difference in capacity and less water sprays back. The corner are less rounded which means even more usable space while still being easy to clean.The only thing I wish for is another hole for a soap dispenser. Our 2nd hole is being used for the dishwasher air-gap.
