A digital shower control can turn a basic bathroom into a more personalized space, but the larger system often depends on compatible valves, trim, and outlets. You may be replacing a pressure-balancing valve, matching a new showerhead to an older setup, or planning a fully integrated system with separate flow and temperature controls. This roundup separates complete controls from individual components so you can match the right part to the job without paying for features your shower cannot use.
The Main Contenders
KOHLER 11748-KS-NA Pressure-Balancing Shower Valve
KOHLER Single Control Valve Kit
Kohler Elate Rite-Temp Valve Trim, Polished Chrome
KOHLER 11748-K-NA Pressure-Balancing Shower Valve
KOHLER 28209-NA Anthem Two-Port Digital Valve
Angle Simple Shower Shut-Off Valve, Chrome
Why These Options Stand Out
A pressure-balancing valve responds to changes in water pressure by helping maintain a steadier outlet temperature. In a busy family bathroom, that makes the KOHLER 11748-KS-NA a practical centerpiece for a showerhead and handshower setup, especially because the diverter is built into the valve body.
Unlike the bare-bones K angle? [No]. Compared with the later KOHLER 11748-K-NA, this KS model adds screwdriver stops, which can simplify access during installation or servicing. Its one-piece diaphragm cartridge also gives maintenance a clear service point, while the brass body suits a primary shower installation.
Useful Highlights
- The pressure-balancing diaphragm helps compensate for pressure changes during a shower.
- An integral diverter supports both showerhead and handshower configurations.
- The one-piece cartridge offers a practical maintenance point.
- A high-temperature limit setting adds a layer of temperature control.
Points To Note
- Compatible trim and the operating handle must be considered separately.
- Confirm the model matches your existing wall opening, plumbing arrangement, and handshower setup.
Key Specs
Who It Suits Best
This valve fits renovators and homeowners installing a concealed shower valve that must serve both a fixed head and a handshower.
A Better Fit Elsewhere
Homeowners wanting app-based control should consider the KOHLER 28209-NA Anthem Two-Port Digital Valve instead.
A dripping single-handle faucet does not always need an entire shower system replaced. The KOHLER Valve Kit is a compact repair component for compatible Coralais single-control faucets, giving you a focused solution instead of changing hardware that may still be in good condition.
Its package measures about 4.92 by 2.83 by 1.57 inches and weighs roughly 0.11 pounds, which makes it easier to handle during a repair. Unlike the KOHLER 11748-KS-NA pressure-balancing valve, this item is a small replacement part rather than a shower pressure-control assembly.
Reasons It Performs
- It targets a specific replacement need instead of requiring a complete faucet replacement.
- The compact package suits straightforward bench or fixture-side repairs.
Practical Considerations
- Compatibility is limited to the specified Coralais single-control faucet applications.
- This valve kit does not provide the shower control, digital settings, or two-outlet management found in larger shower systems.
Made For
You will find this kit most useful when repairing a compatible KOHLER Coralais lavatory or shower faucet with one handle.
Another Choice May Suit
People building a new shower around a fixed head and handshower should favor the KOHLER 11748-KS-NA Pressure-Balancing Shower Valve.
Polished chrome catches the light and gives a bathroom a crisp, coordinated finish, so the visual character of the trim matters as much as the mechanism behind the wall. The Kohler Elate Rite-Temp Valve Trim brings that design cue to a single handle that controls both activation and temperature.
Where the KOHLER 11748-KS-NA provides the concealed pressure-balancing assembly, this TS35320-4-CP piece is the visible trim and handle. Its metal lever has an ADA-compliant design, making it a practical choice for a coordinated renovation that values approachable operation and Elate collection styling.
Why It Works Well
- One handle combines water activation and temperature adjustment.
- The polished chrome finish coordinates with other Elate collection fixtures.
- The metal lever offers straightforward operation for everyday family use.
Small Caveats
- This is trim only, so the compatible valve and showerhead must be handled separately.
Feature Snapshot
The Right Fit
This trim suits someone planning a polished Elate bathroom who needs an accessible single-handle interface.
Consider Something Else When
You need two independently controlled outlets or app-based settings, making the KOHLER 28209-NA Anthem Two-Port Digital Valve a stronger match.
The KOHLER 11748-K-NA handles the basic job of balancing hot and cold water within a concealed shower valve. Its push-button diverter makes it appropriate for installations that serve both a fixed showerhead and a handheld sprayer, a common arrangement in family bathrooms.
Compared with the KOHLER 11748-KS-NA reviewed earlier, this K model omits the screwdriver stops while retaining the 1/2-inch pressure-balancing valve and push-button diverter. For a straightforward replacement, that simpler configuration may be all your existing wall opening requires.
What Makes Sense
- Pressure balancing helps manage temperature changes caused by shifting water pressure.
- The diverter supports a showerhead and handshower from one valve.
Things To Consider
- It is a concealed valve component, not a complete trim, handle, or showerhead package.
- Plumbing layout and wall-opening compatibility need to be checked before ordering, especially when replacing a different model.
Best Suited To
This model fits a renovation or repair centered on a conventional pressure-balancing shower with two outlet types.
Where Another Pick Suits Better
You can choose the Angle Simple Shower Shut-Off Valve instead when your priority is adjustable flow or complete shutoff rather than pressure-balanced temperature control.
This is the true digital centerpiece in the group. The KOHLER 28209-NA uses thermostatic control to manage shower temperature and flow, while two independently controlled outlet ports let one person use a fixed head and handshower separately or choose how each outlet operates.
Unlike the KOHLER Elate Rite-Temp trim, which mainly presents a polished mechanical interface, this valve adds digital functions and optional eco mode. You can operate one outlet at a time to conserve water, and the Konnect app provides access to additional Anthem features, experiences, and system updates.
Where It Helps
- Digital thermostatic control centralizes shower temperature and flow management.
- Two independently controllable ports suit dual-outlet shower layouts.
- Eco mode focuses operation on one outlet at a time.
- The Konnect app expands access to Anthem features and updates.
- A reinforced engineering-grade thermoplastic body supports the valve’s concealed role.
Trade-Offs To Consider
- It requires the compatible Anthem digital control for operation.
- You need compatible outlets and a planned system layout for the two-port functionality to make sense.
Technical Highlights
Built With In Mind
This valve is designed for a connected bathroom with two shower outlets and an existing plan for Anthem-compatible controls.
Swap It Out When
You need a simple mechanical pressure-balancing valve instead, making the KOHLER 11748-K-NA Pressure-Balancing Shower Valve more suitable.
Sometimes the practical shower upgrade is simply a control that lets you reduce the flow while lathering shampoo or stop the water without reaching for another handle. The Angle Simple Shower Shut-Off Valve focuses on that job, with adjustable water volume and complete shutoff capability.
Its all-brass construction and glossy chrome finish suit a basic bathroom update, although it does not provide the digital temperature regulation of the KOHLER 28209-NA Anthem valve. For most straightforward shower arrangements, the direct adjustment may be easier to live with than a more involved control system.
The Practical Payoff
- Water volume can be reduced or completely shut off during use.
- The all-brass body provides a metal-centered construction for a frequently wet space.
- Glossy chrome gives a simple installation a coordinated finish.
Worth Noting
- It manages flow rather than serving as a digital temperature or app-based control.
- Check its connection arrangement and intended placement against your existing shower before ordering.
Quick Facts
Who Will Love This
This option appeals to anyone who wants a straightforward flow restriction and shutoff control without a connected shower system.
Look Elsewhere When
You want digital temperature regulation, two independently controlled outlets, and app-supported features, so the KOHLER 28209-NA Anthem Two-Port Digital Valve fits better.
Build a Shower System That Fits Your Space
Start With the Complete System
A digital shower control may include only the visible control, only the concealed valve, or a larger collection of connected components. Start by identifying what your bathroom already has, including the handle style, valve body, shower outlets, and wall dimensions. The KOHLER 28209-NA Anthem Two-Port Digital Valve is the only fully digital choice here, while the other items serve specific repair, trim, or flow-control roles.
Match the Valve to the Shower Layout
One outlet needs only one control path, while a fixed head and handshower usually call for a diverter. The KOHLER 11748-KS-NA and KOHLER 11748-K-NA both support showerhead and handshower applications, with the KS model adding screwdriver stops. The Anthem valve takes a different approach, offering two independently controlled outlets for a more integrated layout.
Check the Installation Boundary
A trim plate is not a working valve, and a concealed valve does not include every visible fixture. The Kohler Elate trim requires a separate valve and showerhead, while the Angle Simple valve is a flow and shutoff component rather than a temperature-control system. Measure the available wall space, note the connection style, and compare every required piece before planning the installation.
Mistakes to Avoid in Digital Shower Projects
Mistakes Worth Dodging
Do not assume a polished handle includes the valve mechanism behind the wall. Likewise, a pressure-balancing shower valve does not provide app-based control or two digital outlet settings. Match the component to the actual problem, and confirm model compatibility, dimensions, and included pieces before ordering.
What Separates Premium From Basic
A basic valve handles pressure, flow, or an individual trim function. A connected system adds digital temperature regulation, multiple outlet controls, eco mode, and app-supported features. The added cost makes more sense for a planned two-outlet bathroom where separate settings and centralized control matter.
Frequently Asked Questions for Digital Shower Control
Is a digital shower valve the same as a pressure-balancing valve?
No. A digital shower valve uses electronic controls and compatible system components, while a pressure-balancing valve responds mechanically to water-pressure changes. The KOHLER 28209-NA belongs to the digital category, while the Rite-Temp valves provide pressure-balancing control.
Can one valve operate both a showerhead and handshower?
Yes, provided the valve includes a suitable diverter. The KOHLER 11748-KS-NA and KOHLER 11748-K-NA are designed for showerhead and handshower applications, with the diverter built into the valve assembly.
What does a shower valve trim include?
Trim normally includes the visible faceplate and operating handle rather than the concealed plumbing valve. The Kohler Elate Rite-Temp Valve Trim also requires a compatible valve and a separately purchased showerhead.
Can a flow-control valve set shower temperature?
No. The Angle Simple Shower Shut-Off Valve adjusts water volume and can stop the flow, but it does not provide digital temperature regulation. Temperature control requires an appropriate pressure-balancing or thermostatic component.
Is a two-port digital valve useful in a one-outlet shower?
Its two-port capability is unnecessary in a one-outlet installation, and the system still requires compatible Anthem controls. A straightforward pressure-balancing valve is generally the more logical choice for a simple shower arrangement.
The Takeaway
The right shower control depends on the job rather than the number of buttons. Choose the KOHLER 28209-NA Anthem valve for genuinely digital, multi-outlet control, use the Rite-Temp models for pressure-balanced shower and handshower layouts, and select trim or a flow valve only when it completes your existing setup. Confirm compatibility first, and your bathroom will be better for the attention.
