Will a smart bidet seat fit your toilet?
Fit is usually the first question about a bidet seat. A smart seat takes the place of the seat and lid you have now, so it has to sit properly on the bowl you already own.
With SUMO, that question has a short answer. Both seats are universal and fit any WC on the market, so you keep your toilet and add a warm seat, a wash you can adjust and a dryer on top. What’s left to choose is the shape. You can see both seats in the SUMO smart bidet seat range.
Round or elongated: how to tell your bowl
Stand over the toilet and look straight down at the bowl. Toilet bowls come in two main shapes, and you can usually tell them apart at a glance.
- Round: the front of the bowl curves in a short, even arc, and the bowl looks about as long as it is wide.
- Elongated: the bowl reaches further forward into an oval, so it looks clearly longer than it is wide.
Still not sure? Compare your bowl with the two seats in the photos below, or send us a photo on WhatsApp and we’ll tell you which one to pick.

The first two rows are the whole decision. Everything under them comes with both seats.
The U-shaped SC.01-U, for round bowls

The SUMO SC.01-U, U-shaped.
The SC.01-U has a U-shaped seat with a rounded front. It is the seat for a round bowl, so its outline follows the short curve of the rim.
If your bowl looked about as long as it is wide, this is yours. See the SUMO SC.01-U U-shaped smart bidet seat.
The V-shaped SC.01-V, for elongated bowls

The SUMO SC.01-V, V-shaped, seen from above.
The SC.01-V has a V-shaped seat that runs further forward. It is the seat for an elongated bowl, and it follows the longer oval of the rim to the front.
If your bowl stretched out longer than it is wide, pick this one. See the SUMO SC.01-V V-shaped smart bidet seat.
What both seats do once they’re on
After the seat is fitted, the shape stops mattering. Both SUMO seats are designed in Japan, with award-winning design, and they share every feature:
- A heated seat that holds the temperature you choose and adjusts to the room
- The Precision Wash System, a balanced stream that is gentle on sensitive skin
- Water pressure, water temperature and nozzle position you set yourself
- A warm-air dryer with adjustable airflow and temperature
- Self-cleaning nozzles and a deodorising filter that clears odours automatically
- Smart sensors, power-saving modes and quiet operation
- Settings by remote or from the app
Set the wash the way you like it once, and every wash after that follows your settings. Each SUMO smart bidet seat also has a 3-year warranty, onsite in the first year, with an S$80 transport fee in years 2 and 3. The delivery and warranty page has the full terms.
Before your seat arrives
Three quick checks and you’re ready to order:
- Look down at your bowl and note whether it is round or elongated.
- Pick the matching seat: the SC.01-U for round, the SC.01-V for elongated.
- Make sure there’s a power point near the toilet, because the seat is rated 220 V.
Questions
