This is a review of the Los Flexi undermount rectangular sink. It measures 11″ x 16″ on the top of the inside, with a 1″ rim around all sides, making it 13″ x 18″ overall. Perfect for a standard bathroom. It tapers down on all sides to a smaller basin area at the bottom where the drain is. It has an overflow hole near the top to help prevent accidents, but I think these are fairly obsolete – at least I never plug the drain and let the water run and walk away, like a bath in the tub for the kids when they were smaller. Just make sure to pick a drain that supports it. Overall, I really like the style, quality, customer service promise, and the simplicity of this sink. I believe it is going to be the perfect edition to our 2nd upstairs bathroom. We were looking for something similar to what is in there now, but newer/brighter. I love sinks that are not the boring oval standard contractor sinks. Our current one is a 6-sided angular sink, and this is one that is equivalent in style. Overall, I like the product, and I am excited about the bath remodel! I think this sink will look best with a darker top for contrast (grey, charcoal, black, etc.) I look forward to picking one out. I believe that if the sink top were white, the sink may be a slightly different shade and maybe not look right. Also, just thinking a white top will look dirty faster – but it is your choice! So, since I am having trouble getting things figured out and scheduling a contractor around the holidays, I still have a little more work to do. I would have loved to show the full bath remodel, but am just not there yet. I am including a photo of an example color choice (expresso-ish shade) against this sink, and I love the look! Thanks for reading and if you want to jazz up your bathroom space, with a luxury ambiance without breaking the budget, look no further.

Very smooth finish except on the top edge for better adheasion. Overflow drain to stop overfills. Not a very deep sink but deep enough for most uses. Easy to install. Great sink overall for your bathroom.

I appreciate the quality of this sink and that care was given to make sure there were not any burrs or sharp edges. The ceramic is a solid stoneware and the glaze has a nice finish. The top edge is nice and thick and has been ground down smooth to make sure there is a flat and even install under the counter top. This is definitely one of the nicest undermount ceramic sinks I have found and comes with a warranty. The finish ring on the overflow is also a nice touch. (Take note: Sink only, mounting hardware is not included.)
