Problem → Solution

Bathrooms with separate bidet attachments or exposed plumbing can feel cluttered and may require more effort to maintain. Traditional toilet bases can also create hard-to-clean areas around the floor connection, while standard toilets may use more water than necessary.

This model addresses these concerns by combining the toilet and WASHLET into one coordinated system with concealed connections for a cleaner installation. The DYNAMAX TORNADO FLUSH system uses 360° water flow with dual flush operation to help clean the bowl effectively while supporting efficient water usage. The fully skirted design simplifies exterior cleaning, while PREMIST®, CEFIONTECT®, and EWATER+® work together to help reduce buildup and simplify routine maintenance.
