Product Information

Full details

The Crosswater Universal Recessed Installation Box (CROSSBOX) is designed for homeowners looking to future-proof their shower installations, offering a streamlined and flexible approach to upgrading shower technology. Its key benefit lies in its concealed design, minimal installation depth, and compatibility with future finishing kits, ensuring a clean aesthetic and long-term usability. A potential caveat is that it requires a specific Crosswater Crossbox Finishing Kit (sold separately) for full functionality. This system incorporates Vernet thermostatic cartridge technology for safety and comfort, a 3-outlet diverter, and premium controls, all within a super slim 60mm installation depth.

FAQs

What is the main advantage of the CROSSBOX installation box?

The primary advantage is its future-proofing capability, allowing for easy upgrades of the visible shower controls (finishing kit) without re-doing the in-wall plumbing. Its slim depth and flexible installation also speed up the process.

Do I need to buy anything else besides this installation box?

Yes, this is the concealed installation box only. You must purchase a compatible Crosswater Crossbox Finishing Kit separately to operate the shower and control the water flow and temperature.

What is the minimum installation depth required?

The Crosswater CROSSBOX requires a minimum installation depth of 60mm.

How many outlets can this system control?

This is a 3-outlet (3-way) diverter valve, meaning it can manage water flow to three different devices, such as a shower head, bath spout, and a handset.

What water pressure is recommended for optimal performance?

The recommended water pressure is 3 bar. The system is designed to operate between 1 and 5 bar.

Is this product WRAS approved?

Yes, the Crosswater CROSSBOX is WRAS approved.

What is the guarantee period for this product?

Crosswater guarantees the CROSSBOX for 15 years from the date of purchase.

Can I use this with any finishing kit?

No, this installation box is specifically designed to be used only with Crosswater Crossbox Finishing Kits.

Troubleshooting

No water flow or very low flow

Check that the finishing kit is correctly installed and fully open. Ensure the main water supply is on and that there are no blockages in the connected shower head or bath spout. Verify water pressure meets the minimum requirement (1 bar).

Inconsistent water temperature

Confirm the thermostatic cartridge is functioning correctly. Check for any obstructions in the hot or cold water inlets. Ensure the temperature control on the finishing kit is set appropriately. If the issue persists, the cartridge may require replacement.

Diverter not switching between outlets

Ensure the diverter mechanism on the finishing kit is being operated correctly. Check for any internal blockages within the valve body or diverter mechanism. If problems persist, contact customer support for potential internal component issues.

Leaking from the box or connections

Turn off the water supply immediately. Inspect all connections for tightness and ensure appropriate seals or tape have been used. If the leak is from the box itself, there may be a crack or a faulty seal; contact customer support.

Difficulty installing the finishing kit

Refer to the specific installation guide for the Crosswater Crossbox Finishing Kit. Ensure the rough-in box is correctly positioned and that all necessary fixings are used as per the kit's instructions.

  • Ensures user safety with precise thermostatic temperature control.

Cons

Setup, Compatibility & Care

Setup:

  1. Installation of the Box: The CROSSBOX is designed for recessed installation. Its super slim 60mm minimum depth and front/rear mounting options allow for flexibility. Ensure the wall cavity is prepared according to the required dimensions.
  2. Pressure Testing: Utilize the included 'Flush-block' testing plate to perform pressure tests on the system before final trim installation.
  3. Connecting Outlets: Connect your chosen shower head, bath spout, or slide rail kit (sold separately) to the designated outlets using 1/2" connections.
  4. Finishing Kit Installation: Once the main installation and testing are complete, attach the Crosswater Crossbox Finishing Kit (sold separately) according to its specific instructions. This step brings the controls and aesthetic elements to the wall surface.

Compatibility:

  • Required: Must be used exclusively with a Crosswater Crossbox Finishing Kit.
  • Water Pressure: Suitable for systems operating between 1 to 5 bar, with 3 bar recommended for optimal performance (1 bar minimum for HP1).
  • Connections: All connections are 1/2".
  • Outlet Accessories: Compatible with standard shower heads, bath spouts, and slide rail kits.

Care:

  • Cleaning: Clean the external trim using a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
  • Maintenance: The ceramic disc technology and thermostatic cartridge are designed for longevity. For any internal servicing, it is recommended to consult a qualified plumber or contact Crosswater's spare parts department if specific components are needed.
