Mediterranean Sea Pantelleria Waterproof SPC Flooring
These door way surpass anything we could have hoped for. They are sturdy and beautiful. They glide like a breeze.Shopping online is tough. You can have confidence with KFB.
Currently live in Las Vegas, made the trip to get flooring. I arrived as the store was closing (literally locking the doors) they opened up as the staff knew I was driving from out of state. Excellent customer service, will purchase additional flooring to finish remaining rooms. Highly recommended
Sturdy, solid White Oak. Beautifully crafted, designed, and finished. Light enough for one person to move and stable enough to stand without wall-mounting (arrives fully assembled)... I chose this as a bathroom linen closet, but also works as a small armoire for the bedroom or living room, or as a kitchen pantry (or for dishes/cutlery/napkins)
It's really beautiful !!! Vanity and sink are perfectly made, texture, good opening mechanisms, unique color combined with everything (gray oak )This is really the centrepiece of the whole bathroom.

Beautiful, sturdy, good quality. I like the inside which is easy to clean.
Completely delighted!
Love this vanity - it was easy to install and looks great. Slight gap in between the two cabinets, but we don't mind too much. The seamless sinks & countertop are beautiful. Drawer space isn't amazing, but the soft close features and deep cabinets make up for it
Its perfect! Exactly what we were looking for. Made very well. Great price
Cabinet looks great company is easy and friendly to work with.
It's beautiful. Fits the room design perfectly. The high gloss makes it look very high end. People are going NUTS over the vanity. Only caution is we had to cut a slot for plumbing in shelf.
Beautiful addition to our basement bathroom renovation. It is taller than typical vanities, which is perfect for us being a tall family. I love the thick vanity top. I think it will hold up ok. This bathroom is also connected to our daughter�s bedroom, and she loves the storage this vanity has.
Gorgeous!
Exactly what we were looking for!
