A KOHLER smart shower can respond to your voice, but only when it is a compatible DTV+ installation connected to the KOHLER Konnect module and app, local Wi‑Fi, and a linked Amazon Alexa or Google Home account. With that combination, you can start or stop the shower, set or check water temperature, activate saved presets, and—depending on the installed DTV+ configuration—control steam, lighting, and music.
The key limitation is compatibility: the K‑97999 KOHLER Konnect module is an add-on for DTV+ systems, not a self-contained controller for an ordinary manual shower. Existing DTV+ installations may need compatible interface or controller components and software upgrades. This guide explains what is required, which commands are documented, how to set it up, what happens when power or connectivity fails, and how to plan a safe installation.

What do I need to use voice control?
You need four linked pieces: a compatible KOHLER DTV+ shower system, the DTV+ digital interface and system controller required by that installation, the KOHLER Konnect module (model K‑97999), and the KOHLER Konnect app connected to local Wi‑Fi. You then link the installation to an Amazon Alexa or Google Home account. KOHLER’s Quick Start Guide identifies an Amazon or Google account as a requirement for enabling voice control.
The module does not turn a conventional thermostatic or manual shower into a smart shower by itself. KOHLER’s K‑97999 specification describes it as an add-on component for a new or existing DTV+ installation. If you already have DTV+, check the digital interface, system-controller model, and software before buying anything; an upgrade can require additional parts or updates.

Keep the DTV+ interface available even after voice control is enabled. KOHLER says the shower can be operated through that interface without connecting it to KOHLER Konnect, giving you a local control method when connected features are unavailable.
What can I say to the shower?
The documented voice functions cover the core shower controls: water on and off, target-temperature changes, temperature checks, and saved presets. Depending on the DTV+ configuration, the same connected system can also expose experiences involving steam, lighting, and music. Do not assume every installation has every function; the available outlets, valves, accessories, and software determine which commands work.
| Task | Documented capability | Important qualification |
|---|---|---|
| Start the shower | Turn water on by voice | The shower must be powered, connected, and configured for the assistant. |
| Stop the shower | Turn water off by voice | Keep the DTV+ interface available as a fallback. |
| Set temperature | Request a target water temperature | Actual limits depend on the installed valve and its settings. |
| Check temperature | Ask for the current shower temperature | The official guide gives “Check my shower temperature” as an example. |
| Run a preset | Activate a saved DTV+ preset or experience | Only presets and experiences present in the installation can run. |
| Control steam, lighting, or music | Available on documented configurations | Accessory and system configuration determine support. |
KOHLER’s voice-command guide says to ask Kohler to complete the action when using either assistant. Its exact examples are:
- Amazon Alexa:
Alexa, ask Kohler to start my shower.
- Google Assistant:
OK, Google, ask Kohler to start my shower.
Those are the guide’s examples, not a promise that every current assistant, account language, or software version accepts every variation. If a natural-language shortcut fails, use the documented “ask Kohler to …” construction and check the current instructions for your installed system.
How do I check whether an existing DTV+ installation is compatible?
Start with the equipment already in the wall, not with the voice assistant. The K‑97999 specification requires a DTV+ digital interface and a DTV+ system controller. A DTV+ label alone is not enough to establish that a particular valve, controller revision, and software combination supports the module.

- Identify the interface and controller. Record the model numbers from the DTV+ interface, controller, valve, and any accessory modules. Photograph labels before removing trim or opening an access panel.
- Check the current compatibility information. Compare those model numbers with the latest K‑97999 specification and DTV+ Konnect FAQ. KOHLER notes that product specifications can be revised; the cited K‑97999 sheet carries a US‑CA document timestamp of October 8, 2026.
- Ask about required upgrades. An older DTV+ installation may need additional hardware or software before Konnect can be enabled. Treat “existing DTV+” as a starting point, not a guarantee of plug-and-play compatibility.
- Confirm the network location. The FAQ says the DTV+ system and Konnect devices must be on the same Wi‑Fi network for app operation. Plan reliable local coverage at the controller location.
- Verify the installed valve’s limits. Temperature balancing and high-temperature-limit features are specific to the documented valve configuration. Confirm the actual valve model and settings in its current manual.
If the installation records are missing, have a qualified plumbing professional identify the components before ordering a module. A module that does not match the controller or valve will not solve a compatibility problem.

Have the DTV+ system installed and operating through its digital interface, a local Wi‑Fi network with coverage where the system connects, the current KOHLER Konnect app, and an Amazon or Google account ready. Installation work can involve digital valves, controllers, plumbing, and electrical connections, so follow the exact product instructions and applicable local codes.
- Install or confirm the DTV+ hardware. For a new shower, install the compatible valves, controller, interface, and accessories specified for the chosen DTV+ configuration. For an existing shower, confirm that the interface and controller meet the K‑97999 requirements and complete any required upgrade.
- Install the K‑97999 module in an appropriate location. Follow its installation sheet. The module is not water-resistant; do not place it where excessive moisture, high humidity, or condensation can reach it. An accessible, protected location is essential.
- Set up the KOHLER Konnect app. Add the DTV+ system, connect it to the local Wi‑Fi network, and complete the in-app setup. Use the network intended for the permanent installation rather than a temporary guest network.
- Enable the voice feature. In the Amazon Alexa or Google Home app, follow the current KOHLER instructions to link the Konnect service and authorize the DTV+ system. The account used for linking must be the one that will issue commands.
- Confirm device visibility and names. Make sure the assistant can discover the shower and that its name is unambiguous. Avoid duplicate names if more than one bathroom has connected devices.
- Test a low-risk command first. Check the shower temperature before asking it to start. Then try the documented start command with the bathroom clear and a user present.
- Save and verify presets. Create or confirm presets at the DTV+ interface, then test voice activation for each one. A voice command cannot invoke a preset that was never saved or that the installed configuration does not support.
The app and voice assistant are an additional control layer; they do not replace the DTV+ interface. If setup stalls, first confirm that the shower works from the interface, then resolve Wi‑Fi or account linking before changing plumbing hardware.
Is voice control safe for a shower?
Voice control should be treated as a convenience feature, not as the safety mechanism that limits water temperature. KOHLER’s shower-valving specification describes temperature balancing, scald-hazard prevention mechanisms, and a high-temperature limit setting for the documented valve configuration. Confirm that the installed valve has the applicable protections and that its limit is adjusted correctly.
Before allowing anyone to start the shower remotely, verify the temperature at the DTV+ interface and test the selected preset. Children, guests, and people with reduced temperature sensitivity should use settings appropriate to them; a voice request for a target temperature does not override the valve’s configured limit or compensate for an incorrectly installed system.

Use the exact installation instructions for the valve, controller, interface, and K‑97999 module. Plumbing and electrical requirements vary with the system. Follow local plumbing and electrical codes and have a licensed professional handle work inside walls, at valves, or near electrical supplies.
What happens if Wi‑Fi or power fails?
Konnect voice and app features depend on the system’s required local Wi‑Fi and power. KOHLER’s FAQ states that DTV+ and Konnect features cannot be used during a power loss unless backup power is available. The reviewed documents do not establish that voice commands continue to work without the required connectivity and power, so do not plan on voice operation during an outage.
KOHLER says DTV+ can be operated through its digital interface without connecting to KOHLER Konnect. That makes the interface the practical fallback for a temporary internet, Wi‑Fi, account, or voice-assistant problem. Confirm that the interface is reachable and that household members know how to use it before relying on connected controls.
How do I troubleshoot a command that does not work?
Work from the physical system outward. This sequence separates a plumbing or controller issue from an assistant-linking issue.
- Use the DTV+ interface. If the interface cannot start, stop, or adjust the shower, voice troubleshooting will not fix the underlying system problem.
- Check power. Confirm the controller and module have power and that no breaker, service switch, or protected receptacle has tripped.
- Check Wi‑Fi membership. Verify that the phone running Konnect, the DTV+ system, and the module are on the intended local network. The FAQ’s same-network requirement applies to app operation.
- Check account linking. In Alexa or Google Home, confirm that the KOHLER service remains linked and that the correct household account has access to the shower.
- Use the documented phrase. Say “ask Kohler to” followed by the action, as shown in the official guide. Try a simple temperature check before a multi-step preset.
- Check the installed feature set. Steam, lighting, music, and some experiences require corresponding DTV+ hardware and configuration. A command for an absent accessory will fail even when voice linking is correct.
- Review software and current instructions. Existing installations may require an upgrade, and KOHLER may revise specifications. Use the latest guide for the exact models rather than relying on an old setup screen.
Do not repeatedly issue a start command while diagnosing a delayed response. Look at the interface and physical shower area first so a late command does not produce an unexpected start.

Should I add voice control to an existing DTV+ shower or specify it for a new build?
The right path depends on what is already installed. For an existing DTV+ shower, adding the K‑97999 module can be practical when the interface, controller, valve, software, and network location are compatible. For a new build, specify the complete DTV+ configuration together so the valve, controller, outlets, accessories, and controls are designed as one system.
| Situation | Questions to resolve before purchase or rough-in | Likely next step |
|---|---|---|
| Existing compatible DTV+ | Do the interface and controller meet K‑97999 requirements? Is an upgrade needed? Is protected Wi‑Fi available? | Confirm compatibility with the current specification, then install and link the module. |
| Existing shower without DTV+ | Are you prepared for digital valves, a controller, new wiring, plumbing access, and wall work? | Plan a DTV+ conversion as a construction project; the module alone is not a retrofit controller. |
| New smart-shower project | Which outlets, steam, lights, music, presets, assistant, and fallback controls are required? | Choose the complete compatible DTV+ arrangement and document every component before rough-in. |
For a construction schedule, coordinate the plumber, electrician, tile or access-panel installer, and smart-home setup. Leave service access for the controller and module, protect the module from shower moisture, and record model numbers and software versions for future troubleshooting.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should I verify before relying on presets and accessories?
Ask the installer to demonstrate each function that matters rather than assuming that a DTV+ label includes every feature. Verify each water outlet, temperature range, preset, steam function, light, speaker or music control, and the behavior of the physical interface. KOHLER describes DTV+ with Konnect as combining control of water, steam, lighting, and music, but the available functions depend on the installed configuration.

Before enabling voice operation, read the current KOHLER Konnect, Amazon Alexa, or Google Home privacy policies for your region and account type. The availability of the module, regional support, and retailer stock can also change, so confirm local availability and the current specification before ordering.

Because the module’s cited specification says KOHLER may revise product specifications, save the installation documents that match your project date and recheck the manufacturer’s current instructions when replacing a controller, resetting the network, or expanding the system.
How we evaluated the practical setup
This guide focuses on the documented requirements and boundaries: compatibility with DTV+, the K‑97999 module’s role, local Wi‑Fi and account linking, commands shown in KOHLER’s voice guide, operation through the DTV+ interface, power and connectivity dependencies, and the safety and moisture warnings in the product documents. It does not treat a voice assistant alone as a shower controller, and it does not assume that every DTV+ installation has the same accessories or software.

Can I upgrade my existing DTV+ to work with KOHLER Konnect?
Often, but compatibility must be checked against the installed DTV+ interface, system controller, valve, and software. KOHLER identifies the K‑97999 as an add-on for DTV+ and notes that existing installations may need additional parts or upgrades; it is not a universal retrofit for a manual shower.
Do the shower and my phone need to be on the same Wi‑Fi network?
KOHLER’s FAQ says the DTV+ system and Konnect devices must be on the same local Wi‑Fi network for app operation. A guest network, changed router, or isolated access point can therefore make the app appear to lose the shower even when the plumbing is working.
Can I use voice control when the electricity is out?
Do not count on it. KOHLER states that DTV+ and Konnect features cannot be used during a power loss unless backup power is available, and the documents do not establish voice operation without the required power and connectivity.
Where can the K‑97999 module be installed?
Install it only in a location protected from excessive moisture, high humidity, and condensation. The specification says the module is not water-resistant, so it should not be placed in the wet area simply because the shower itself is designed for water exposure.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesWhat should I do if Alexa or Google does not understand a command?
Use the wording pattern in KOHLER’s guide: address the assistant and say “ask Kohler to” complete the action. Start with a simple temperature check, confirm the Konnect link and local network, and then test presets or accessory functions supported by the installed DTV+ configuration.
