Client Review

Our customers aren't afraid to tell the world that we've done a great job for them,
because they value our quality, work ethic and skills.


When remodeling our one small bathroom, we were looking for easy upkeep along with something stylish and good looking.  We initially considered tile and stone, but the upkeep, grout cleaning, etc. wasn't ideal.  We had cultured stone about 20 years ago and really didn't want to go back to the 90's look. However, we checked out several cultured stone suppliers in the Bay Area and still weren't impressed with the styles. 

Then we went to Ordaz Cultured Marble & Onyx in Concord.  Right off the bat we were impressed with the large showroom and  unique cultured stone they produce... didn't see anything else other places that compared with the natural looking products of Ordaz.  Rebecca and other staff were knowledgeable, helpful and personable; great first impression. Owner came to our house and measured; installation was done in two steps and the finished product is outstanding.  Best shower EVER!

They worked with our contractor to assure the shower down-time was minimal and that was a real plus.  I know tile and stone is the going thing right now, but really, for ease of care and stlye, take a look at what Ordaz has to offer.  Quick squeegee, daily shower spray and you're done!
