Q: Would you explain the differences between the Straight Wall, Square Wall or Coved Wall variations?
A: Each of these options are provided to satisfy different personal, functional and budget choices: The straight wall option is built to allow the shower wall panels to extend directly to the floor of the shower pan and are the most requested and economical shower pan. This straight wall option will accommodate the thickest shower walls of all that Grifform® offer. Generally used with shower walls of heavier weight, like Granite where the weight is baring primarily on the floor. The square wall option provides for the shower wall panels to sit on a ledge nearly 3” from the shower pan floor with a square corner at the wall and floor line. The coved wall option is the premier offering, providing a smooth round inside corner at the floor and inside corners of the pan. This coved option also provides for the shower wall panels to set up above the floor as with the square option and both of these types allow for ¼” and ½” material thicknesses. Both the square and coved options allow for different wall material alignments as you prefer.
Q: How do I know the shower pan will fit?
A: We will generate drawings based on your specific information, which you can compose in the product request form. Open the product tab on the home page and select an item by clicking on the item you wish to preview. Options will appear and information will allow you to enter dimensions specific and variations to your shower pan needs. Upon processing your order, drawings will be produced that represent what will be built to your request.

Unlike any other shower materials, the cleaning renews the surface and will help it look like new. Soap film, dirty grime and body oils are easily cleaned without fear of damage and rinsed away. Because the material is non-porous it does not harbor bacteria or molds that makes it ideal for use in the shower and bathroom areas.

After installing the Grifform® pan the new shower walls or panels can be installed over the existing walls to complete the installation. This has been recognized as a major advantage in both time and rubbish removal.
Q: Do you have different threshold options?
A: Grifform® has possibly the largest variation of shower pan options anywhere. Entries vary from the more traditional smooth, straight lined curbs or entries with overhanging top caps. Level joining floors are often referred to as no-egress entries while shallow raised ramps are called low-egress. Although these general types are customary, building to meet individual requirements are consistently needed and satisfied.
Q: Is the material used too slick to be used as a shower floor?

A: This is one of the most commonly asked questions and perhaps the one with the most possible answers. Grifform® has designed the shower pan unit to be the most adaptable unit of its kind for the use of differing adjoining materials. As different materials are applied on the shower walls it changes the location of the pan to the wall when installed. You can follow the rough in guide that will direct you through how to determine the right placement for your choice of wall surfacing material.
Q: What is different about the Classic shower pan?
A: The Grifform® “Classic” shower pan is built following the industry standard sizes, shapes and basic colors. Another commonality with most other stock shower options are the drains are centered which makes upgrading from fiberglass or acrylic showers much easier. Grifform® Classic pans also provide tub replacement sizes in right and left hand models. Tub replacement is one of the most common upgrades in almost all renovation projects.
Q: Do you have non-obtrusive threshold options?
A: Grifform® has many different configurations that satisfy those having reduced mobility. However growing numbers are using this option just because they like the appearance and flexibility it affords them later. Many options are being employed now that were not considered necessary in the very recent past. Grifform® has embraced this growing need providing tub replacement units that are made specifically for this application with level and shallow ramping entries for easy wheel chair and walker access.
Q: Are there any options for extra slip resistant surfacing on shower or bathroom floors.
A: The Grifform® shower pans and floors are constructed of solid surface material with a gradual slope. Grifform® provides a slip resistant surface on all “Barrier Free” models as a standard specification. This surface treatment has been certified to be in conformance with ADA requirements.
Q: What is a Trench Drain Pan?
A: The Grifform® shower pans have many different demands one is to prevent water to exit the shower without likely hood of possible accidental blockage. This can be more likely when garments or toweling items might be dropped inside the shower compartment. There is a greater potential for this kind of event happening in these ADA situations. For the added protection Grifform® developed this system built of solid surface materials that is durable, inconspicuous and provides easy tool-less removal of the trench cover for easy cleaning.
