Frequently asked questions


Q: Where are your products made?
A: The manufacturing location varies by product. We manufacture in China, Mexico, Cambodia, and Vietnam. Please refer to the specific product details for more information.
Q: How can I purchase one of your vanities or shower doors?
A: At any retail or wholesale distributor in our Where to Buy section. Vanities and shower doors are not able to be purchased directly by a consumer.
Q: I am a contractor/designer. Can I purchase directly from you?
A: Contractors or designers interested in ordering product in large quantities may inquire about setting up an account. For single orders or smaller projects, we can provide the best service to you if you work with one of our wholesale distributors.
Q. Why does the product contain a cancer warning and/or a birth defects and developmental harm warning?
A. Under California’s Proposition 65, The Safe Drinking Water and Toxic Enforcement Act of 1986, businesses selling products to California consumers are required to provide specified warnings as to a product containing any amount of nearly 1,000 listed chemicals that can be touched by the user’s hands unless the business can prove that the level is such that the chemical poses no significant risk of cancer and, for some chemicals, is less than 1/1,000 of a “no observable effect level.” Companies who do not provide warnings are subject to enforcement lawsuits by California residents seeking injunctions and penalties of up to $2,500 for every unit sold. They need not prove, and never do prove, that anybody was caused any damage by the product. We have never heard of a person sustaining cancer or reproductive harm as a result of using any of our products. Accordingly, we believe it is highly probable that the exposures, if any, are far below the no significant risk level and no observable effect level divided by 1,000. However, developing and presenting the scientific evidence and testimony a business needs to prove the level of exposure can cost between many hundreds of thousands of dollars and millions of dollars in legal costs. Accordingly, in order to keep our product costs at a minimal level and prevent this expensive litigation, we place the warning on each of our products that we believe contains a listed chemical, even though it is probable that the level of exposure is sufficiently low that no harm is caused.


Q: Are filler strips available for your vanities?
A: At this time, we do not manufacture any filler strips for our vanities.
Q: Is extra stain available for purchase?
A: Stain is available in pen form for the touching up of minor scratches, dents, and flaws. We do not carry stain in larger containers.
Q: What is the name or brand of stain used on your vanities, and where can I purchase it?
A: The stain used on our vanities is a custom stain mixed by our factories. Unfortunately, our stains are not available for purchase.
Q: Do your products contain formaldehyde?
A: All commercial grade finishes contain some levels of formaldehyde. Foremost vanities meet or exceed CARB-2 requirements implemented by the state of California.
Q: What is MDF?
A: MDF, or Medium Density Fiberboard, is an engineered wood product.

Shower Doors

Q: What measurements do I need to choose a shower door?
A: The height and width of the finished opening is needed to choose a shower door size.
Q: I don’t have my finished measurements yet. Can I choose a shower door with measurements of my rough opening?
A: Since many of our shower doors are made to order, some retailers may not accept returns. We recommend that you wait until the area is finished to ensure that you choose a door in the correct size.
Q: I want to purchase a custom Marina unit. How do I obtain pricing information?
A: Through a retail or wholesale distributor. The distributor will assist you in the quoting process.
Q: What needs to be provided for a custom shower door quote?
A: A hand-drawn sketch with finished height, width, and centerline (middle-of-threshold) dimensions. In addition, glass type and finish color should also be provided.
Q: I just received my new shower door. Which side is the H2OFF technology on?
A: The H2OFF technology will always be on the side of the panel opposite of where the sticker is located.
