What's the difference between the Tile-Basin® & ShowerSlope™
The ShowerSlope™ is identical to the Tile-Basin® with two exceptions. The ShowerSlope™ DOES NOT come factory prepped with an elastomeric waterproofing membrane coating, or with factory installed perimeter components (i.e. flange or curb). This allows the ShowerSlope™ to be "cut-to-fit" in the field. An elastomeric waterproofing membrane must be properly applied to surfaces of the ShowerSlope™ and to the seams where the ShowerSlope™ and the tile backer board meet.
What is the shower base made of?
We start with a 3-pound high density EPS core and shape the base with a 1/4" per foot (2%) slope to the drain. In its raw state, the 3-pound EPS is tough; however, both surfaces (top & bottom) are then coated with a proprietary blend of hard coat epoxies and embedded composite fibers that gives the shower base its ultimate durability and strength. Next, the perimeter flange and curb are fusion welded to the sloped core. It is then coated in our elastomeric waterproofing and crack isolation membrane. It is completely waterproof and ready-to-tile.
What is the flange?
The flange is a 1/8" thick, 5" high FRP composite MATERIAL that is designed to rise between the stud wall and the showers backer wall. The flange provides a water barrier to prevent water from exiting he shower during normal use, or in case of a "back-up". The flange is fusion welded to the perimeter of the shower base's core. This exclusive feature increases the likelihood that any moisture that was to penetrate the shower wall would exit into the shower base area, and not to the outside of the shower pan. A flange is attached to the perimeter of the shower base's sloped core where a "curb" or "ramp" is not located
What is the curb or ramp?
The "curb" or "ramp" is sometimes referred to as the threshold. The curb is the perimeter component of a shower pan that you "step over"(curb) or "roll up"(ramp)when entering a shower. Our standard size curb is 4 inches (high) X 4 inches (deep) X (variable length). Our standard size ramp has a 6" "run" (the part that you roll up when entering the shower). The length of a curb or ramp depends on the shower bases individual specifications. - We can customize both the curb and/or the ramp upon request (additional charges may apply). The curb is also where the shower door or glass block wall is placed. We can make the curb as long as you prefer: half curb, whole curb, double curbs or radius curbs. Ramp options are more limited.
How do you install the shower base?
Using a 3/4" U-notched trowel (supplied with all Tile-Basins), trowel some modified thin-set into the area that the basin is to be installed (Important: do not use a "premixed" thin-set. It will not cure properly). Liberally apply a bead of polyurethane sealant (found at most home centers) around the outside perimeter of the drain's flange. Then set the Tile-Basin® in place, and ensure that it is well embedded in the thin-set. The thin-set takes care of any floor imperfections and is the adhesive that holds the base in place. Bolt the locking ring on the 4 bolts, and you have actually bolted the base to the flange. You can now stand on the base immediately and start your wallboard installation. What used to take days has been reduced to less than an hour.
What kind of thin-set should I use?
Any quality "polymer modified" thin-set will do just fine. Do not use a premixed thin-set (i.e.... water already added). A premixed thin-set that comes in a bucket with water already added will not cure properly. Remember: No premix! Always add your own water! Different terms for modified thin-set include: modified thin-set, modified thin set with a latex additive, fortified thin-set, polymer modified thin-set, polymer fortified blended thin-set. The thin-set must meet or exceed ANSI A118.4 and ANSI Al18.11 requirements when mixed with water.
Three most recognized brands:
1. Custom Building Products: usually found at The Home Depot. (Product Names: Versa Bond, Fortified, FlexBond Fortified and their elastic membrane is called Red Gard)
2. Laticrete: usually found at The Home Depot, Lowe's and other tile suppliers. (Product Names: Laticrete 254 Platinum and their elastic membrane is called Hydro Ban).
3. Mapei: usually found at The Home Depot, Lowe's, Daltile and other tile suppliers (Name of product: Ultra Flex 2 and their elastic membrane is called Aqua Defense)
What kind of shower drain is recommended?
A standard (PVC or ABS) 3-piece tile shower drain that uses a "clamping ring", will work fine. We sell these drains on our online store; however, this same type drain is available at most home improvement stores. Make sure you choose a brand that will allow the "strainer barrel" (the threaded part that holds the strainer) to thread down "flush" with your finished tile. We recommend, but do not require, the Oatey brand tile shower drain (this is the brand that we sell).
What size hole do I cut in the sub-floor for the tile drain?
If you have purchased one of our tile shower drains, you will need to cut a 5" hole in the sub-floor. The drain's "body" will need to recess into the sub-floor with the drain body "flange" supported by the sub-floor. Instructions on how to properly install a tile shower drain are available with every shower base we sell.
How far down do I cut my pipe for the tile shower drain?
1 3/4" inches below the top surface of the sub-floor will work as per our instructions; however, we strongly recommend that you determine this measurement once you have the tile shower drain "in your hands".
Will the drain fit to a cast iron pipe?
There are adapters available. We do not sell these adapters. We recommend that you consult with a local plumber, or plumbing wholesaler about this issue. Local codes can vary.
Why do I need to use furring strips?
Two good reasons! "Furring strips" are long thin strips of wood (or other material) used to extend your shower's tile backerboard beyond the KBRS shower base's flange. This allows the bottom of the backerboard to "sit" inside of the shower base. The flange is allowed to "free float" between the backerboard and the wall studs. This method is a "leak-protection" feature exclusive to only KBRS shower bases (patent pending). By allowing the backerboard to sit inside of the shower base, you will be ensuring that any moisture that may penetrate the tile walls, will exit into the sloped area of the shower base, and exit down the drain (where it belongs). You may also find that your shower's stud walls are "out-of-square". You can also use the furring strips to correct this issue if desired (we recommend it).
Is there any size KBRS can't or won't make?
The short answer is....we haven't found one yet. We love a challenge.
How long does it take to make a custom shower base?
Our average lead-time is 7-10 business days (Mon-Fri). This could slightly vary due to certain manufacturing conditions, in which if this becomes an issue you will be contacted and notified by a KBRS, Inc. representative.
Can you frame on top of the curb?
Yes, as long as the wall is not a "load bearing" wall. Our curbs are tough enough to handle heavy glass shower enclosures, and glass block walls. We only build the best.
Does square drain strainer fit a round pipe?
Yes. It will connect to a 2" PVC pipe.
How can I ensure that the shower base is completely embedded in the thin set after I set int in place?
Typically, professional installers use boxes of tile or buckets of water to supply a uniform weight to the shower base until the thin-set is cured. Following this procedure will result in a "rock-solid" installation. Also, be sure to securely tighten the shower drain's "clamping ring" to the drain body in the sub-floor as recommended in the installation instructions.
Is the drain kit included when I order a shower base?
The drain kit is included in our ShowerSlope™ cut-to-fit kits, but not with individually sold Tile-Basin® or ShowerSlope™ products; you can purchase a tile drain on our online store with an accessory pack OR as a single item.
I am installing my shower base on a wood sub-floor. Can I apply thin-set directly to the wood sub-floor?
If your sub-floor is structurally sound (no rotting...etc.) and level (very important), then applying thin-set directly to the sub-floor is okay. However, we do not recommend applying thin-set directly to particleboard.
How easy is a ShowerSlope™ to install?
Very easy. It requires simple "handyman" skills to install a ShowerSlope™. A ShowerSlope™ can be "cut-to-fit" in the field and can be adhered to the sub-floor using an even layer of troweled latex modified thin-set. The ShowerSlope™ uses a standard tile drain. No need to re-plumb for a special drain. In most cases, your existing tile shower drain can be reused to connect to a ShowerSlope™.
Is the ShowerSlope™ waterproof?
Yes! One of the purposes of the ShowerSlope™ is to assist in the construction of a mortar-free, leak-free shower. Waterproofing the joints between the ShowerSlope™ and the tile backer board can be accomplished using our elastomeric waterproofing membrane ShowerSeal®. Elastomeric waterproofing membranes can also be purchased at most professional tile distributors or your local home center.
Can the shower seats be cut-to-fit on site?
Yes, the corner seat, ladies leg ledge and bench seats can be cut on site to any size using a common handsaw. Small adjustments can be made using a hand held orbital sander equipped with 80-grit sandpaper. The exposed area will need to be re-coated with ShowerSeal® waterproofing.
Can you texture and paint over ShowerSeal®?
Our Tile-Basin® product is a 100% waterproof unit. We coat the shower base with our elastomeric membrane, ShowerSeal®. The ShowerSeal® acts as a second waterproof layer, and primer for thin-set. This is our use of the product. We suggest calling your local paint professional for their expertise in regards to painting over the membrane.
Do our shower seats set on top of the basin or on the sub-floor?
Yes, our shower seats are meant to be installed on top of the basin or slope and not out on the sub-floor for a proper and water tight fit. (Note: some trimming may be required)
