Vogt VE.350 3/4″ High-Flow Thermostatic Shower Valve Rough-In

The Vogt VE.350 3/4″ High-Flow Thermostatic Valve Rough provides the in-wall control needed for multi-outlet shower systems that require substantial water delivery and independent outlet management. Its combination of thermostatic temperature regulation and three integrated volume controls makes it suitable for custom residential bathrooms, renovations, and ensuite projects where several shower functions are incorporated into one coordinated installation.

A 3/4″ connection and rated flow capacity of up to 45 L/min, equivalent to 12 gpm (US) at 60 psi, allow the valve to support shower configurations with significant water requirements. The available flow capacity is appropriate for systems incorporating multiple compatible outlets, such as rain showers, hand showers, body sprays, and additional water features. This configuration provides a suitable foundation for larger or more function-rich shower layouts.

Three integrated volume controls give each connected outlet independent water-flow management. Instead of treating the shower system as one combined outlet, users can adjust the amount of water supplied to individual functions according to how the system is being used. This arrangement is particularly useful for multi-function showers where different outlets may be operated separately or as part of a customised bathing routine.

Thermostatic technology provides temperature regulation alongside the individual volume controls. The valve is designed to respond to changes in water pressure and supply conditions, helping maintain a more stable water temperature during operation. This can reduce the need for repeated manual temperature adjustments and adds greater control to shower systems where water demand can change as different outlets are activated.

The VE.350 is a rough-in valve, meaning it is installed behind the finished wall during the plumbing stage. Once the wall is completed, compatible trim components can be installed to provide the visible controls and finished appearance. This concealed configuration keeps the valve assembly out of sight while allowing the exposed shower components to coordinate with the bathroom’s overall design.

Since the rough valve is intended to be paired with compatible trim components, installation planning should include verification of the selected trim, plumbing requirements, installation depth, and outlet configuration. Professional installation should also follow manufacturer guidelines and applicable local Canadian building and plumbing requirements.

The Vogt VE.350 is certified to ASME A112.18.1/CSA B125.1 and ASSE 1016 standards. These certifications provide documented standards compliance relevant to the valve’s intended plumbing application and support its use in professional residential installations across Canada.

For custom showers requiring three independently managed functions, the VE.350 brings high-flow capability, thermostatic temperature control, and integrated volume management into a single concealed rough-in assembly. Its 3/4″ connection and 45 L/min flow rating provide the capacity for demanding shower layouts, while the three integrated controls offer practical management of multiple compatible outlets.
