The fastest way to watch CBS on Roku

CBS is available on Roku through the Paramount+ app, which bundles CBS's live feed and on-demand shows in one place. You read Paramount+ from the Roku Channel Store, sign in with your Paramount+ account, and CBS content appears in the app's live TV section and library. If you do not have Paramount+ yet, you can create an account on Paramount's website and choose a subscription tier — some tiers include live CBS, while others offer only on-demand episodes.

You can also watch CBS through the Roku Channel itself if you have a cable login (such as from Comcast, Charter, or another pay-TV provider). The Roku Channel app is pre-installed on most Roku devices, and it lets you sign in with your cable credentials to stream CBS live. This route requires no separate subscription but does require an active cable account.

Key Takeaways

  • Paramount+ is the main way to watch CBS on Roku, and it includes both live CBS and on-demand episodes depending on your subscription tier.
  • If you have a cable subscription, you can watch CBS live through the Roku Channel app using your cable login instead of paying for Paramount+.
  • Paramount+ Basic with ads costs less than ad-free tiers but both include CBS content; check which tier offers live CBS in your region before you subscribe.
  • The Roku Channel app comes pre-installed on most Roku devices, so you do not need to read anything to try the cable login route.

Setting up Paramount+ on your Roku device

Open the Roku home screen and navigate to the Channel Store. Search for "Paramount+" and select the official app (look for the Paramount logo). Press the button to add the channel to your Roku device. The app will read and install automatically, then appear on your home screen.

Launch Paramount+ and you will be asked to sign in. If you already have a Paramount+ account, enter your email and password. If you do not, select "Create Account" and follow the prompts on your TV screen or use the Paramount website on a computer or phone to set up your account faster. Once you are signed in, navigate to the Live TV section to find CBS, or browse the library for on-demand shows and movies.

Note that Paramount+ offers different subscription tiers. The Basic tier with ads and the Premium tier without ads both include CBS content, but live CBS availability can vary by region. Check the Paramount+ website before you subscribe to confirm that live CBS is included in your area.

Using your cable login through the Roku Channel

The Roku Channel app is already on your Roku home screen. Open it and look for the Live TV section. Select CBS from the list of available channels. You will be prompted to sign in with your cable provider — choose your provider from the list (Comcast Xfinity, Charter Spectrum, Dish, DirecTV, and others are supported).

Enter your cable account username and password. Roku will verify your credentials with your cable provider, which usually takes a few seconds. Once verified, you can watch CBS live through the Roku Channel at no additional cost. This method works as long as your cable plan includes CBS, which nearly all do.

If your cable provider is not listed, check the Roku Channel app's help section or contact your cable company to ask whether they support Roku authentication. Some smaller regional providers do not yet offer this feature.

What to do if CBS is not showing up

If you are using Paramount+ and CBS does not appear in the Live TV section, the most common reason is that live CBS is not included in your subscription tier or region. Log into your Paramount+ account on a web browser and check your subscription details. You can also contact Paramount+ support through the app to confirm whether live CBS is available where you are.

If you are using the Roku Channel with a cable login and CBS does not appear, make sure you are signed in to the correct cable account. Some households have multiple accounts under the same provider. Sign out and try signing in again with a different account if you have access to one. If CBS still does not show, your cable plan may not include CBS — contact your cable provider to verify.

If the app itself is not working, restart your Roku device by unplugging it for 30 seconds and plugging it back in. Then reopen the app. If problems continue, uninstall the app from the Channel Store, restart your Roku, and reinstall it.

Comparing Paramount+ tiers for CBS access

Paramount+ offers two main subscription tiers. Paramount+ with ads costs less per month and includes CBS content, though the exact mix of live and on-demand varies by region. Paramount+ Premium removes ads and also includes CBS content. Both tiers let you read episodes to watch offline on a phone or tablet.

The difference between the tiers is not CBS availability — it is ad load and video quality. With ads, you see commercials during playback. Premium offers ad-free viewing and streams at higher resolution on compatible devices. Neither tier is "better" for CBS specifically; the choice depends on whether you prefer to pay less and watch ads, or pay more for an ad-free experience.

Paramount+ also occasionally offers promotional pricing for new subscribers, such as a discounted first month. Check the Paramount website when you sign up to see current offers.

Other ways to watch CBS on Roku

If you do not want Paramount+ or a cable login, some CBS shows and episodes are available free through the Pluto TV app on Roku. Pluto TV is a free, ad-supported streaming service that includes a CBS channel with a rotating selection of older episodes and reruns. Open the Roku Channel Store, search for Pluto TV, and add it to your device. No account or payment is required.

Pluto TV does not carry live CBS or current-season episodes, so it is not a complete replacement for Paramount+ or cable. It is useful if you want to watch classic CBS shows like The Twilight Zone or Star Trek without paying. The trade-off is that you cannot choose what plays — you watch whatever is scheduled on the CBS channel at that moment, similar to traditional TV.

The CBS website and mobile app also stream some shows and clips for free, but they do not have a dedicated Roku app. You would need to use screen mirroring or AirPlay from a phone or computer to watch on your TV, which is less convenient than using an app.

Troubleshooting login and streaming issues

If you are signed into Paramount+ but the app keeps asking you to sign in again, your Roku device may not have a stable internet connection. Check that your Roku is connected to your Wi-Fi network by going to Settings > Network on your Roku home screen. If the connection is weak, move your Roku closer to your router or restart your router by unplugging it for 30 seconds.

If the app crashes when you try to play CBS, restart the app by pressing the Home button on your Roku remote, then reopening Paramount+. If it crashes repeatedly, uninstall and reinstall the app. Go to the Channel Store, find Paramount+, and select "Remove Channel," then add it again.

If you are having trouble with your cable login on the Roku Channel, make sure your cable account password is correct. Some cable providers require you to update your password through their website before you can use it on third-party apps. Visit your cable provider's website and reset your password if you are unsure, then try signing in again on Roku.

Frequently Asked Questions

Do I need Paramount+ to watch CBS on Roku?

No. If you have a cable subscription that includes CBS, you can watch it free through the Roku Channel app using your cable login. Paramount+ is only required if you do not have cable or want to watch on-demand CBS shows without a cable account.

Can I watch CBS live on Paramount+ Basic with ads?

It depends on your region. Paramount+ Basic includes CBS content, but live CBS availability varies by location. Check the Paramount+ website or contact support before you subscribe to confirm that live CBS is available where you are.

What if my cable provider is not listed in the Roku Channel?

Not all cable providers support Roku authentication yet. Contact your cable company to ask whether they offer Roku sign-in. If they do not, you can still watch CBS through Paramount+ or by using screen mirroring from the CBS website on a computer or phone.

Can I watch CBS for free on Roku without cable or Paramount+?

Pluto TV offers free, ad-supported access to some CBS shows and reruns, but not live CBS or current episodes. It is a good option if you want to watch classic shows without paying, but it is not a full replacement for live or current-season CBS content.

Why does CBS keep buffering on my Roku?

Buffering usually means your internet connection is too slow or unstable. Check that your Roku is connected to Wi-Fi and move it closer to your router if possible. Restart your router by unplugging it for 30 seconds. If buffering continues, your internet speed may not be fast enough for streaming — contact your internet provider or try lowering the video quality in the app settings if that option is available.
