Hello Manny, The C100 and C200 WASHLETS are available in round options. We do not really recommend the use of the WASHLET on the Entrada. It can be installed, but the Entrada base tapers in the back and does not fully support the body of the unit. One must then take great care not to apply unnecessary torque or force onto the WASHLET unit in order to prevent premature wear. Please take a look at round versions of the Drake toilet to better suit the WASHLET. We hope that you will give it a try and thank you for your interest in TOTO!
Hello, Yes. The overall width (just under 19 inches) includes the control panel. You can view the spec sheet here: https://images.homedepot-static.com/catalog/pdfImages/eb/eb02425b-c0e2-4690-9f5e-2549b310597f.pdf I hope this is helpful and thank you for your interest in TOTO!
No. You need an elongated toilet because the seat takes some space in the back.
