Setup and Installation
The KOHLER Archer bath is designed for alcove installation. Proper installation is crucial for optimal performance and longevity. It is recommended to consult a qualified plumber for installation.
Pre-Installation Considerations:
- Drain Assembly: This bath requires a K-7271 or K-7272 Clearflo slotted overflow bath drain, which is sold separately. Ensure you have the correct drain assembly before beginning installation.
- Space Requirements: Verify that the installation space accommodates the bath's dimensions (approximately 63.62"L x 34.5"W). Note that this model is wider than some standard 30-inch bathtubs.
- Leveling: Accurate leveling is essential. Some installers recommend a mortar bed installation for stability, especially in enclosed alcoves where access for leveling blocks might be limited.
- Plumbing: Ensure plumbing for the drain and faucet (if applicable) is correctly positioned for a right-hand drain configuration.
Installation Steps (General Guidance):
- Prepare the alcove according to local building codes and manufacturer's detailed instructions (not provided in this general manual).
- Install the drain and overflow assembly onto the bath.
- Carefully position the bath into the alcove.
- Level the bath using the integrated leveling system or a mortar bed, ensuring stability and proper drainage slope.
- Connect the drain to the household plumbing system.
- Secure the bath to wall studs as per manufacturer guidelines.
- Perform a leak test by filling the bath with water and checking all connections.

Maintenance
Regular cleaning and proper care will help maintain the appearance and functionality of your KOHLER Archer bath.
- Cleaning: Clean the acrylic surface with a soft cloth or sponge and a non-abrasive, mild bathroom cleaner. Avoid harsh chemicals, abrasive scrubbers, or solvents, as these can damage the finish.
- Stain Removal: For stubborn stains, use a cleaner specifically designed for acrylic surfaces. Always test the cleaner in an inconspicuous area first.
- Preventing Scratches: Avoid dropping heavy or sharp objects into the bath. Do not use abrasive cleaning tools.
- Drain Maintenance: Periodically remove and clean the drain stopper and overflow plate to prevent buildup and ensure proper drainage.
Troubleshooting
This section addresses common issues you might encounter with your bath.
- Slow Drainage:
- Check if the drain stopper is fully open.
- Inspect the drain for hair or debris buildup. Clean the drain assembly as described in the Maintenance section.
- If the issue persists, a clog further down the plumbing system may require professional attention.
- Water Leaks:
- Immediately turn off the water supply if possible.
- Inspect all connections around the drain and overflow for tightness.
- Check the seal between the bath and the surrounding surfaces. Re-caulk if necessary.
- If a leak originates from the bath itself, contact KOHLER customer support.
- Surface Scratches/Gouges:
- Minor surface scratches on acrylic can sometimes be buffed out with a specialized acrylic repair kit.
- For deeper gouges or chips, professional repair may be required.
- Bath Feels Unstable/Flexes:
- This can indicate improper leveling or insufficient support during installation.
- Consult a professional to assess the installation and reinforce the bath if necessary.
