Finally, a toilet built for big & tall bodies. Most toilets are designed around an average frame. The Tersova STKK50 isn't. With a 19.25" extra-wide seat, a 19.25" seat height (nearly 4" taller than a standard toilet), and a 32.5" extended bowl, it's engineered for taller and larger users who've spent their whole lives on toilets that were too small, too low, and too cramped — without giving up any of the smart bidet features Trone is known for.

The STKK50 is a Big & Tall toilet with extra length, height, and width. The STKK50 will showcase brand new innovative features such as Efoam, Aromatherapy, UV Sterilization, and Infrared Therapy. 

• Efoam Technology -  Automatically release of a refreshing 'potpourri' foam, diffusing a delightful scent throughout the bathroom. The foam is also anti-splashing, and helps keep the bowl cleaner for longer.
• Aromatherapy - The fine infusion of pleasant scents not only masks unpleasant odors but also promotes a sense of well-being and calmness, turning your daily routine into a spa-like retreat for both your body and mind.
• Keeping Your Toilet Spotless and Sanitized -  UV sterilization helps eliminate harmful bacteria and germs, ensuring a more sanitary and hygienic toilet environment. By effectively killing bacteria and viruses, UV sterilization contributes to minimizing the risk of infections and illnesses associated with traditional toilets.

• Infrared Therapy - Infrared therapy can help stimulate blood flow, promoting better circulation and potentially alleviating discomfort or pain. The gentle warmth of infrared therapy can help relax your muscles and reduce tension.

What is a big & tall toilet?
- A toilet built larger than standard in every dimension — longer bowl, wider seat, and taller seat height — for taller and larger users. The STKK50 is 32.5" long with a 19.25" wide seat at a 19.25" seat height.

How much taller is the STKK50 than a normal toilet?
- Standard toilets sit around 15–16"; "comfort height" is about 17". The STKK50's seat is approximately 19.25" — noticeably taller than either.

Will it fit where my current toilet is?
- In most bathrooms, yes — it uses the same standard 12" rough-in as a normal toilet. It needs a GFI outlet within 4 feet.

Is the STKK50 ADA compliant?
Yes.
