4. Setup and Installation
The Signature Hardware Sitka tub is designed for a three-wall alcove installation with a right drain placement. It features a pre-leveled base for easier setup. Professional installation is recommended.
4.1 Pre-Installation Steps
- Inspect the Tub: Before installation, thoroughly inspect the tub for any manufacturing defects or shipping damage.
- Prepare the Alcove: Ensure the alcove dimensions are appropriate for the 60"L x 30"W x 21.25"H tub. The alcove should be plumb, level, and structurally sound.
- Plumbing Rough-in: Verify that the drain and overflow rough-in locations align with the tub's specifications (right drain placement).
4.2 Tub Placement and Leveling
- Carefully position the tub into the prepared alcove.
- Since the tub has a pre-leveled base, minor adjustments may be needed to ensure it is perfectly level. Use a spirit level to confirm.
- Connect the drain and overflow assembly (purchased separately) according to the manufacturer's instructions for the drain kit. Ensure all connections are sealed properly to prevent leaks.

4.3 Securing the Tub
- Once the tub is level and drain connections are made, secure the tub to the wall studs using appropriate fasteners (not included) through the integrated tiling flange.
- Apply a waterproof sealant (e.g., silicone caulk) along the edges where the tub meets the wall to prevent water penetration.
- Perform a leak test by filling the tub with water and checking all drain and overflow connections for any signs of leakage.
5. Operating Instructions
The Signature Hardware Sitka tub is designed for a calm and relaxing soaking experience. Its acrylic construction helps maintain water temperature longer.
- Ensure the drain stopper is closed before filling the tub.
- Fill the tub with water to your desired level, ensuring it does not exceed the overflow opening. The maximum water capacity is 59 gallons, with a water depth of 14-1/2 inches to the overflow.
- The textured bottom provides slip resistance; however, always exercise caution when entering and exiting the tub.
- After use, open the drain stopper to empty the tub.
6. Care and Maintenance
Proper care will ensure the longevity and appearance of your acrylic bathtub. Acrylic is non-porous and easy to clean, requiring minimal maintenance.
- Regular Cleaning: For daily cleaning, use a soft cloth or sponge with mild, non-abrasive soap and warm water. Rinse thoroughly after cleaning.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, steel wool, or harsh chemicals (e.g., acetone, paint thinner, strong acids, or alkalis) as these can damage the acrylic surface.
- Stain Removal: For stubborn stains, a diluted solution of white vinegar and water can be used. Apply, let sit briefly, then rinse thoroughly.
- Prevent Scratches: Avoid dropping sharp or heavy objects into the tub.
- Maintain Shine: Periodically, you can use a non-abrasive liquid polish designed for acrylic surfaces to restore luster.
