SHOWERSLOPE™ FREQUENTLY ASKED QUESTIONS

PRODUCT QUESTIONS

WHAT IS THE DIFFERENCE BETWEEN A TILE-BASIN® AND A SHOWERSLOPE™?

TILE-BASIN® VS SHOWERSLOPE™

What's the difference between the Tile-Basin® and 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), the ShowerSlope™ can also be cut-to-fit in the field, where as the Tile-Basin® cannot.

WHAT IS THE SHOWERSLOPE™ MADE OF?

UL® Certified expanded polystyrene (Type XV-EPS 60) geofoam core sandwiched between two composite epoxy materials (CEM). 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.

HOW THICK IS THE SHOWERSLOPE™?

All standard shower slopes are 1.5" thick, custom shower slopes are typically 1.5" thick as well UNLESS they are custom manufactured with a T2 drain - T2 drains require the ShowerSlope™ to be minimum of 2" thick. Additionally, if the drain is more than 49" or 50" off any side, then the slope is 2" thick to adjust for a proper 2% slope and thickness at the drain.

HOW DO YOU INSTALL A SHOWERSLOPE™?

SHOWERSLOPE™ INSTALLATION

The ShowerSlope™ requires simple "handyman" skills to install. 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™.

HOW DO YOU INSTALL A LINEAR SHOWERSLOPE™?

LINEAR SHOWERSLOPE™ INSTALLATION

The Linear ShowerSlope™ requires simple "handyman" skills to install. A Linear 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 Linear ShowerSlope™ uses a linear shower 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 Linear ShowerSlope™.

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 of the 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 RedGard)
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)

WHICH TROWEL SHOULD I USE?

In most cases, KBRS shower pan products include both a 3/4" U-Notched Trowel, and a 1/2" Square Notched Trowel. Which trowel you will need will depend on how high your drain is set "above" the sub-floor. Please refer to the guide below to determin which trowel to use for your shower installation.

3/4" U - NOTCHED
TROWEL

Drains 3/8" above the sub-floor, use the 3/4" U-Notched Trowel.

1/2" SQUARE NOTCHED
TROWEL

Drains 1/8" above the sub-floor, use the 1/2" Square Notched Trowel.

WHAT IS THE DIFFERENCE BETWEEN A T1 AND T2 DRAIN?

T1 DRAIN TYPE

T1 Drain = 1/2” depth at drain, low profile drain set. T1 Drains will accommodate Oatey 130 Series shower drains purchased through ShowerBase.com. All standard KBRS shower bases are manufactured with a T1 drain type.

T2 DRAIN TYPE

T2 Drain = 1” depth at drain, generally for deeper drain sets. T2 Drains will accommodate most other drains where the strainer is no wider than 4 .” wide and no more than 1” tall. T2 drains can be manufactured for custom shower bases upon request.

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). We must have the part # if you want to use a different drain than what is available with KBRS.

ARE THERE RESTRICTIONS WITH CUSTOM DRAIN LOCATIONS

While KBRS can manufacture any shape, size and drain location for a custom shower pan, it is recommended drain location must be 7" (minimum) for T1 (standard base) and 8" (minimum) for T2 (custom base) from the any side of a shower base because this can make tiling difficult during installation, and visibly steep.

WHAT SIZE HOLE DO I CUT IN THE SUBFLOOR FOR THE SHOWER DRAIN?

If you have purchased one of our tile shower drains, you will need to cut a 4-1/2" 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 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".

DOES A SQUARE DRAIN STRAINER FIT A ROUND PIPE?

Yes. It will connect to a 2" PVC pipe.

IS THE DRAIN KIT INCLUDED?

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 a shower accessory pack OR as a single item.

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.

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 MANUFACTURE A CUSTOM SHOWER PAN?

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 I ORDER A RAMP ATTACHED TO THE SHOWERSLOPE™?

Yes! We can custom manufacture a ramp attached to a ShowerSlope™. We can also add a radius on a custom ramp per your specifications. You can also order a 61" ramp, cut it on site and attach it yourself in the field if you prefer.

HOW CAN I ENSURE THAT THE SHOWER BASE IS COMPLETELY EMBEDDED IN THE THIN-SET AFTER I SET IT 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.

I AM INSTALLING ON A WOOD SUBFLOOR, CAN I APPLY THIN-SET DIRECTLY TO THE SUBFLOOR?

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.

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.

WHAT SUBSTRATES ARE SUITABLE FOR SHOWERSLOPE™ INSTALLATION?

  • Suitable for any level substrate that you would normally build a tile shower on (concrete, approved plywood surface, etc.)
  • Deflection of substrate not to exceed 1/360th of the span 1/2 inch (12 mm) in 15 feet (4.6 m) in accordance with ANSI A108.01-2.3
  • Allow for live and impact load as well as dead load weight of pan, tile and setting beds.

WHERE CAN I INSTALL A SHOWERSLOPE™?

ShowerSlope™ products can be installed interior, exterior, as wet floors and as commercial or residential shower applications.

WHAT TILE TYPES ARE SUITABLE FOR SHOWERSLOPE™?

  • Pebbled Tile
  • Impervious Porcelain
  • Gauged or Ungauged Natural Stone Tile
  • Vitreous, Semi-vitreous or Non-Vitreous Tiles, Quarry, Cement Body Tile
