Product Overview
The Design House Oakmont Bath and Shower Trim Kit offers a blend of classic style and reliable performance for your bathroom. This kit features a dual-handle design for precise temperature control and is finished in satin nickel for enhanced durability and corrosion resistance. The brass waterways ensure safe and clean water delivery. Designed for efficiency, the 1.8-gallon-per-minute high-pressure shower head provides an invigorating experience while conserving water. A pull-up diverter spout allows for easy control of water flow direction. The complete kit includes a shower head, slip-on tub spout, two-handle trim, and the necessary valve.
The two-handle design allows for separate adjustment of hot and cold water. Please note that this system does not automatically regulate temperature like pressure-balanced systems, so water temperature may fluctuate if other fixtures are in use. Installation is designed to be straightforward, suitable for both DIY enthusiasts and professionals. The valve can be pre-adjusted during installation to set your desired hot and cold water temperature range. The low-maintenance satin nickel finish is resistant to water spots and fingerprints, simplifying cleaning and ensuring long-lasting shine. This product is certified by ADA, cUPC, and WaterSense, guaranteeing quality and compliance with industry standards.

Operating Instructions
Operating the Design House Oakmont Bath and Shower Trim Kit is straightforward, providing control over water temperature and flow.
Water Temperature Control:
- The kit features a dual-handle design. One handle controls the hot water supply, and the other controls the cold water supply.
- Turn the respective handles to increase or decrease the flow of hot or cold water to achieve your desired temperature.
- Since this is not a pressure-balanced system, water temperature may experience minor fluctuations if other water fixtures in the household are in use simultaneously.

Water Flow and Diverter:
- To activate the shower, pull up the diverter knob located on the tub spout. This will redirect water flow from the tub spout to the shower head.
- To return water flow to the tub spout, push the diverter knob down.
- The shower head delivers a high-pressure flow of 1.8 gallons per minute (GPM), designed for an efficient and satisfying shower experience.

Maintenance
Proper maintenance will ensure the longevity and aesthetic appeal of your Design House Oakmont Bath and Shower Trim Kit.
Cleaning the Finish:
- The satin nickel finish is designed to be low-maintenance and resistant to water spots and fingerprints.
- To clean, use a soft, damp cloth and a mild, non-abrasive soap.
- Avoid using harsh chemicals, abrasive cleaners, scouring pads, or polishes, as these can damage the finish and void the warranty.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
Shower Head Nozzle Cleaning:
- Over time, mineral deposits can accumulate in the shower head nozzles, potentially affecting spray performance.
- Many modern shower heads feature flexible rubber nozzles that can be easily cleaned by gently rubbing them with your finger or a soft brush to dislodge deposits.
- For stubborn deposits, a solution of white vinegar and water can be used. Soak the shower head (if removable) or apply the solution to the nozzles, then scrub and rinse.
Troubleshooting
This section addresses common issues you might encounter with your bath and shower trim kit. For problems not listed here, or if solutions do not resolve the issue, contact customer support or a qualified plumber.
Issue: Water Temperature Fluctuations
- Possible Cause: The Oakmont kit features a dual-handle design that does not include a pressure-balancing valve. This means that changes in water pressure from other fixtures (e.g., flushing a toilet, running a washing machine) can affect the temperature of the water flowing from the shower or tub.
- Solution: This is a characteristic of the product's design and not a defect. To minimize fluctuations, avoid using other high-demand water fixtures while showering or bathing.
Issue: Low Water Flow from Shower Head
- Possible Cause: Mineral buildup in shower head nozzles or a partially closed shut-off valve.
- Solution: Clean the shower head nozzles as described in the Maintenance section. Ensure that the main water supply valves are fully open.
Issue: Leaks Around Handles or Spout
- Possible Cause: Loose connections, worn washers/o-rings, or improper installation.
- Solution: Carefully check all connections for tightness. If the issue persists, it may require replacing internal components or re-sealing connections. It is recommended to consult a qualified plumber for these repairs.
