Using this unit is fun and easy, as this is thanks to the side control panel. The panel allows you to access different settings, from a heated set to an oscillating massage and warm air dryer. All you need is to touch on the setting that you desire, and you’re good to go.

Heated seat

Sitting on the toilet in cold mornings or in winter is quite challenging. This is because the toilet seat is cold and unbearable to use. However, Brondell Swash SE400 changes everything as it features a heated seat. Like Brondell Swash CS1000 seats, you can adjust the temperature of the seat to suit your preference.

Adjustable water temperature and pressure

Apart from adjusting the seat temperature, you can also change the water pressure and temperature to suit your needs. Pick a gentle spray or oscillating spray. The heated tank ensures that you get warm water every time you use the bidet toilet.

Warm air dryer

Not every individual has an easy time cleaning their nether area after finishing their business. So, when the wand ends its cleansing job, you can turn on the warm air dryer so that you can leave feeling great and not wet. That’s why many people are replacing tissue paper with bidet toilet seats. But the model doesn’t feature an air deodorizer which is found in the Toto washlet C200 and Toto C100 electronic bidet seats.

Illuminating nightlight

Waking up at night to visit the toilet can be stressful, more so if there is a bright light. This toilet simplifies things for you as it has a cool blue nightlight that illuminates to guide you to where the toilet is based. So, the light won’t interfere with your sleep as much as the bright light would.

One-touch auto mode

Are you in a hurry to do your business quickly? Simply press the one-touch auto mode, and the toilet will do the rest for you. This is a convenient feature, especially for a household with many people.

Question: Why use the cleaning wand instead of toilet paper?
Answer: With the ever-changing technology, bidet toilet seats have made using the toilet to be more convenient as you don’t have to use tissue paper. Toilet paper doesn’t clean as well as a cleaning wand. Aside from that, it is not very hygienic. But when you use a cleaning wand, you save water and trees. This is because toilet paper is manufactured from trees and uses a lot of water in the process. As a result, cleaning yourself using a cleansing wand is more economical and saves the environment.

Question: Is this a round or elongated bidet seat design?
Answer: This particular Brondell Swash SE400 bidet toilet seat is of an elongated configuration. However, the manufacturer also offers a round-bidet seat design for the same model so that you can use it on your round-shaped toilet bowl. You can select the right design for your toilet, depending on whether you’ve got a round or elongated bowl design.

Elongated toilet bowl designs are the best, as they can accommodate most people. Also, they offer more comfort when compared to round bowl toilets. On the other hand, round bowl toilets take up less space, and that’s why they are perfect for compact bathrooms.
