Go big
Color: Black
I had a very small holder that barely held anything, the I stumbled on this in the small size, which I almost bought because it was a little bigger than what I had. Then I saw this one and I'm glad I bought the larger one because it holds everything! I even bought a glass container for the dish soap. Fits perfectly in the space. I also like the idea of the stone to absorb water instead of it dripping in a tray that runs through a spout into the sink.

LOVE MY SINK CADDY!
Color: Black
This caddy is such a game changer for my kitchen. It keeps everything neat and in one place AND no more clutter around the sink! I can fit my soap, sponges, and brushes easily, and it still looks nice on the counter. The drying base really works too! It absorbs water fast and doesn’t get gross like other trays I’ve had. It’s sturdy, doesn’t slip, and even looks kind of decorative. Definitely worth it!

Great product.
Color: Black
I love it. Good design , well made and very large capacity. Easy to assemble. Keeps my counter free from cleaning items and drys out my sponge so it doesn’t get mildew. It’s very stable , not flimsy at all. Great price too.

Great Sink Caddy
Color: Black, Color: Black
Great size and you can configure it to accommodate a range of soaps and gadgets. The brush holder can be moved to the outside for more storage area in the main basket. The little divider adjust across the wires and it stays in place. The stone bottom absorbs drips quickly and I haven’t noticed any discoloration on it. It stays in place on the sink edge. Perfect for my organization needs and keeps the area neat vs tossing the brushes on the ledge leaving water marks on the counter. It was packaged well and the coating seems good! I bought a cheaper one and it came bent, with the coating popped off in several places. This one is worth paying a little bit more for the quality!
