2. Safety Information
- Professional Installation Recommended: Installation of this product should be performed by a qualified professional to ensure proper function and adherence to local building codes.
- Weight Distribution: The tub must be installed on a level, structurally sound subfloor capable of supporting the weight of the tub, water, and user(s).
- Mortar Base Requirement: For acrylic tubs, it is critical to set the tub in a wet mortar bed or equivalent structural support to prevent flexing, cracking, and ensure long-term stability. Failure to do so will void the warranty and can lead to product damage.
- Hot Water Safety: Always test water temperature before entering the tub to prevent scalding.
- Chemical Use: Avoid using abrasive cleaners or harsh chemicals that can damage the acrylic surface. Refer to the Maintenance section for cleaning guidelines.
- Electrical Safety: If installing any electrical components (e.g., whirlpool jets, heaters), ensure all electrical work is performed by a licensed electrician and complies with all local electrical codes. This model is a soaking tub and does not include electrical components.

4. Setup and Installation
This section outlines the general steps for installing the PROFLO PFS6042RSK alcove soaking tub. Always consult local building codes and employ a qualified professional for installation.
4.1 Pre-Installation Checks
- Ensure the installation area is clean, level, and structurally sound.
- Verify rough-in dimensions match the tub specifications (60" L x 42" W).
- Confirm drain location is on the right side as required for this model.
- Inspect the tub for any shipping damage before installation.
4.2 Preparing the Alcove
- Frame the alcove opening to the exact dimensions required for a snug fit, allowing for wall finishes.
- Ensure the subfloor is level and prepared for the mortar bed.
4.3 Drain and Overflow Connection
- Install the drain and overflow assembly according to the manufacturer's instructions for the specific drain kit being used (not included with tub).
- Ensure all connections are watertight.
4.4 Setting the Tub in Mortar
Critical Step: Failure to properly support the tub base will void the warranty and can lead to structural damage.
- Mix a sufficient quantity of mortar (e.g., Type S or Type N masonry cement) to a thick, workable consistency.
- Apply a 2-3 inch thick bed of mortar evenly across the entire subfloor area where the tub base will rest. Ensure the mortar covers the entire footprint of the tub bottom.
- Carefully lower the tub into the wet mortar bed. Press down firmly and evenly across the bottom of the tub to ensure full contact with the mortar.
- Use a level to verify the tub rim is perfectly level in all directions. Adjust as necessary while the mortar is still wet.
- Allow the mortar to cure completely (typically 24-48 hours) before proceeding with further installation steps or filling the tub.
4.5 Securing the Tub
- Once the mortar is cured, secure the tub flange to the wall studs using appropriate fasteners (e.g., galvanized screws) at recommended intervals.
- Apply a waterproof sealant (e.g., silicone caulk) along the joint between the tub rim and the wall surface to prevent water penetration.
5. Operating Instructions
The PROFLO PFS6042RSK is a soaking tub designed for a relaxing bathing experience.
- Filling the Tub: Ensure the drain stopper is closed. Turn on the faucet and fill the tub to the desired level. Always monitor the water level to prevent overflow.
- Draining the Tub: Open the drain stopper to allow water to empty. Ensure the drain is clear of obstructions for efficient draining.
6. Maintenance and Cleaning
Proper care will maintain the appearance and longevity of your acrylic tub.
- Regular Cleaning: Clean the tub regularly with a soft cloth or sponge and a non-abrasive, mild liquid cleaner specifically designed for acrylic surfaces.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, wire brushes, or harsh chemicals (e.g., acetone, paint thinner, strong acids/bases) as these can scratch or damage the acrylic finish.
- Stain Removal: For stubborn stains, use a diluted solution of white vinegar and water, or a specialized acrylic tub cleaner. Rinse thoroughly after cleaning.
- Preventing Scratches: Avoid dropping heavy or sharp objects into the tub. Do not use the tub as a work surface.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tub feels soft or flexes when standing in it. | Improper base support; tub not set in mortar. | This indicates a critical installation error. The tub must be removed and re-installed with a proper mortar bed for support. Failure to do so will lead to cracking. |
| Cracks appearing in the tub surface. | Lack of proper base support, excessive weight, impact damage, or use of harsh chemicals. | If due to improper installation, re-installation with mortar is required. For minor surface cracks, professional repair may be possible. Significant cracks may require tub replacement. |
| Slow draining. | Drain obstruction (hair, soap scum). | Clear the drain of any blockages. Use a drain snake or a chemical drain cleaner safe for plumbing and acrylic. |
| Water leaks around the tub. | Improperly sealed drain/overflow, damaged plumbing, or inadequate caulking around the tub rim. | Inspect all plumbing connections and the caulking. Re-seal or repair as necessary. Consult a plumber if the source of the leak is not apparent. |
