5. Setup and Installation
Proper installation is critical for the longevity and performance of your CKB Shower Base. Professional installation is highly recommended.
5.1 Site Preparation
- Ensure the subfloor is level, clean, and structurally sound to support the weight of the shower base, water, and user.
- Confirm that the drain rough-in is correctly positioned according to the shower base dimensions (refer to Image 4.1). The shower base is designed for a standard 2" compression fitted drain (not included).
- Prepare the wall studs for proper backing and support where the flanges will attach.
5.2 Drain Configuration
The CKB Shower Base features a unique reversible drain design, allowing for either left or right drainage to accommodate various bathroom layouts.
- Identify the desired drain orientation (left or right) based on your plumbing setup.
- The linear drain cover is removable for access to the drain opening.
5.3 Flange Installation
The shower base includes three detachable aluminum water dam flanges, offering flexibility for different threshold configurations:
- Zero Threshold: No flanges are used, creating a flush entry.
- Single Threshold: One flange is installed along the wall where the shower base meets the wall.
- Dual Threshold: Two flanges are installed on two adjacent walls.
Attach the flanges to the shower base and secure them to the wall studs as per standard plumbing practices, ensuring a watertight seal. Use appropriate fasteners (not included) and sealant.

5.4 Setting the Shower Base
- Apply a generous bead of silicone sealant or appropriate adhesive to the subfloor where the shower base will rest.
- Carefully position the shower base onto the prepared area, ensuring it is level in all directions.
- Connect the shower base drain opening to the existing drain pipe. Ensure a secure and watertight connection.
- Allow the sealant/adhesive to cure completely before proceeding with tiling or wall finishing.

6. Operation
The CKB Shower Base is designed for standard shower use. Its pre-sloped design ensures efficient water drainage towards the linear drain. The 304 stainless steel drain grate is designed to prevent larger debris from entering the drain while allowing water to flow freely.
- Ensure the linear drain cover is properly seated before using the shower.
- The pre-sloped surface directs water effectively to the drain, minimizing standing water.
7. Maintenance and Cleaning
Regular cleaning and maintenance will preserve the appearance and functionality of your CKB Shower Base.
- Daily Cleaning: After each use, rinse the shower base thoroughly with water to remove soap residue and prevent buildup.
- Routine Cleaning: Clean the shower base regularly with a soft cloth or sponge and a mild, non-abrasive cleaner. Avoid harsh chemicals, abrasive pads, or scouring powders, as these can scratch or dull the acrylic surface.
- Drain Maintenance: Periodically remove the stainless steel linear drain cover to clear any hair or debris that may have accumulated in the drain channel. This helps maintain optimal drainage. The 304 stainless steel is rust-resistant and easy to clean.
- Stain Removal: For stubborn stains, use a cleaner specifically designed for acrylic surfaces. Always test the cleaner in an inconspicuous area first.
- Avoid Impact: Do not drop heavy or sharp objects onto the shower base, as this can cause chips or cracks.
8. Troubleshooting
This section addresses common issues you might encounter with your shower base.
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow Drainage | Hair or debris in the drain; partial clog in plumbing. | Remove the linear drain cover and clear any visible obstructions. If the problem persists, a plumbing professional may be needed to clear the drain pipe. |
| Water Pooling | Improper leveling during installation; drain obstruction. | Ensure the drain is clear (see "Slow Drainage"). If the base is not level, professional re-installation may be required. The base is pre-sloped, so pooling indicates an installation issue or clog. |
| Leaks Around Base | Improper sealing of flanges or drain connection. | Inspect all sealed areas, especially around the flanges and drain connection. Reapply silicone sealant as necessary. Professional assistance is recommended for persistent leaks. |
| Surface Scratches/Dullness | Use of abrasive cleaners or materials. | Use only mild, non-abrasive cleaners and soft cloths for cleaning. Minor scratches on acrylic can sometimes be buffed out with specialized acrylic repair kits. |
