I am doing some small projects in my mom's outdated bathroom. We are replacing her old round toilet with a taller comfort height elongated toilet seat. I asked the plumber about a bidet for mom. The plumber mentioned that he has also sold a few Kohler bidet toilet seats. (The bidet is in the seat and has a warming function.) I was just wondering if anyone has found this helpful and effective? Mom has vascular dementia and sundowning and finds the hygiene challenging so the aide helps her but it is sometimes difficult. The elongated seat will bring a bit more room. I was just wondering about a bidet. She has never had one.
