What Customers Are Saying

The vanity top has a mixed reception, with some finding it a good value with a sleek, modern design, while others report quality issues like scratching, chipping, and receiving damaged products. The sink basin is also criticized as being too shallow. Availability and compatibility of matching backsplash and side splash pieces is another major concern, as these need to be purchased separately and may not be in stock.

I would understand if maybe 1 out of 2 orders arrived with some sort of damage, but 4 out of 4 have arrived in unusable condition. Either the QA process for these tops is awful, how they package them is terrible, or a combination of the two. Either way, I would absolutely not recommend this v...

Same size. He did have to caulk it.

I bought a new sink. Fast delivery, but the plumber I hired charged me $750.00 to install it.
