10 Best Shower Valves 2025 in the United States

The GROHE 29137000 Grohtherm SmartControl Dual-Function Shower Thermostatic Valve Trim Kit is a shower valve designed to cater to diverse shower setups with its three valves. This functionality allows users to switch between or combine different spray patterns and water outlets, making it suitable for those who desire versatility in their shower experience by incorporating hand, head, side showers, and a bath filler. The customizable control buttons with clear icons provide an intuitive user interface, enhancing ease of use for all household members. For safety, the valve includes the GROHE SafeStop button that limits temperature to 100°F (38°C), preventing the risk of scalding and ensuring a comfortable shower experience for families with children or elderly members.

Constructed from durable metal and featuring a GROHE StarLight chrome finish, the valve promises longevity and resistance to tarnish, making it a good investment for a long-lasting bathroom fixture. However, the product's rough-in set is sold separately, which could be an inconvenience for buyers expecting a complete kit. Additionally, while the valve supports multiple functions, its single-handle operation might require some getting used to, especially for users accustomed to more traditional setups. The high water consumption rate of 7.7 gallons per minute may not be ideal for those looking to conserve water.

The GROHE 29137000 offers a blend of advanced features and durability. Potential buyers should consider the additional purchase requirement for the rough-in set and the relatively high water usage.

The Delta Faucet MultiChoice Universal Integrated Shower Diverter Rough is a versatile and reliable option for those looking to upgrade their shower system. This product acts as both a mixing and diverter valve, making it suitable for a variety of shower configurations. Compatible with standard plumbing systems, it features universal inlets and outlets that connect easily with both NPT and copper pipes, simplifying the installation process.

The valve is designed for back-to-back installations, making it a good choice for shared walls in bathrooms. One of its noteworthy features is the pressure balance valve, which maintains water temperature within a safe range, protecting against sudden fluctuations in hot or cold water pressure. This can be particularly beneficial for families with young children or elderly members.

The valve body is made of brass, a durable material that ensures longevity, and it comes with a lifetime limited warranty from Delta Faucet, providing peace of mind regarding its durability. However, it is important to note that this product is a rough-in valve, which means additional trim kits are required to complete the installation. Additionally, the lack of built-in stops may require shutting off the main water supply for maintenance.
