The attractive combination of an unglazed, smooth finish, and random variations in tone create a stylish complement for a wide variety of design schemes. This tile is constructed from durable slate material and features a semi-vitreous water absorption rating. NOTE: Inspect all tiles before installation. Natural stone products inherently lack uniformity and are subject to variation in color, shade, finish, etc. It is recommended to blend tiles from different boxes when installing. Natural stones may be characterized by dry seams and pits that are often filled. The filling can work its way out and it may be necessary to refill these voids as part of a normal maintenance procedure. All natural stone products should be sealed with a penetrating sealer. After installation, vendor disclaims any liabilities.

Rated 4.8 out of 5 by 61 reviewers.
Rated 4.0 out of 5.0 by Great to look at This product had me from the moment I saw it online. When I opened the first box, I was a bit taken back, because it did not look quite the same as i thought it would. It was very dusty and dirty, and I was concerned it would not end up looking like I had hoped. It was very easy to cut and work with, and very strong (sometimes slate can be flakey until you get it glued and sealed, making it fragile while taking it out of the box and moving it around, not this stuff.) At the end of the project after plenty of sealing, it looks STUNNING. All in all a GREAT choice. Easy to clean AFTER sealed, but you must clean repeatedly prior to sealing it. February 5, 2013
Rated 5.0 out of 5.0 by Absolutely amazing tile - don't think about it, buy! Wow, this slate is amazing stuff. I ordered it because the reviews were great and since the closest price available anywhere else was nearly 50% more (i.e. $5 per square foot). At $30 for a box, this is a STEAL. The quality is top notch - in 100 square feet, I only had two corners that weren't full (slimmed down on the top - still usable along edges of the floor), and one tile that I considered not installing because of weird pits & surface profile. I did anyway - it adds interesting texture. It cuts like butter with the ryobi handheld wet tile saw, I haven't had one accidentally break yet. Installation is like any other tile - no issues there. The color is very dark - a rich charcoal gray that I expect will become darker when it is sealed. I've uploaded 2 pictures... this is unsealed under natural light. The grout is gray, and is still being cleaned up a little. It was shipped directly from the manufacturer, and only took 5 days by freight. The company called two days in advance to schedule the delivery, and was very professional. The slate came strapped to a pallet. My experience with this was so good that I've since ordered another 200 sq feet for our kitchen and laundry room. We're very much looking forward to when it is all installed. January 1, 2014
Rated 5.0 out of 5.0 by Cannot go wrong! We are remodeling our Victorian farmhouse and thought these slate tiles would look great for kitchen floors. Keeps true to the style of the house but also gives it a more updated/modern feel. Could not be happier. Great pair with our soapstone counter tops. You cannot beat the price or go wrong in our opinion. September 11, 2013
Rated 5.0 out of 5.0 by Love, Love, Love this tile!!!!! I originally purchased this tile for a bathroom, and I loved it so much, I purchased it for my wet bar area as well. Contractor said it was easy to work with and remarked that he would like to use it in his home as well. Best price I could find for quality tile. I placed my order online and went to the store for pickup. They had it ready and loaded in my car in minutes. I highly recommend this product!!! May 20, 2014
Rated 5.0 out of 5.0 by Get it! This tile is so great! So much less expensive than other slate tile at tile stores. My tiler said it was great quality and easy to install. I love it! It looks much more expensive than it was!! October 30, 2013
Rated 5.0 out of 5.0 by Hooked Couldn't be happier with the product. I really wanted Vermont milled slate for the color & cleft, but I chose this product for the value. I'm glad I did. You won't find a cheaper slate out there. We ordered 1600 sqft for every room of our home (except 1, the office). We live in a mid-rise mid-century condominium and we wanted a stylish alternative to wood (which is a pain in the neck to glue down/rip up from concrete). This tile offered the period look we were shooting for, but with a modern edge. We laid it in a running bond with light grey grout. It looks awesome. My only warning: seal seal seal before grouting. & clean grout IMMEDIATELY. Our contractor was great but still had a hard time getting the residue out of the stones clefts. Clefting is minimal with this product, but any crease will hide away grout until it dries. Cleanup is easy, mop/bucket/woolite once a week or so. Delivery was a breeze. We received 3 pallets without a single broken tile. They are heavy as sin. Be ready for heavy lifting. My only complaint is that the tile doesn't come in a versaille or random pattern option.

Rated 5.0 out of 5.0 by This product is beautiful once you've applied an enhancer/sealer. I hired the installation since we were also adding a heated floor mat underneath and I didn't want any issues. (I highly recommend the heated mat.) The tile was very bland out of the box, but once the enhancer was applied, it looked/looks great. My only issue was with the person who delivered the product...he dropped each of the boxes of tile on my driveway from two feet in the air. None of the tiles broke, so that was a bonus.

Rated 5.0 out of 5.0 by This tile is the BEST! This tile is exactly what we were looking for for our kitchen remodel, and the price can't be beat! The quality is excellent, it cut like butter with a wet tile saw, and looks amazing. Could not be happier with our purchase; liked it enough we ordered it for the bathroom too! February 10, 2015
