Does anyone have a bidet for the elderly?

There are bidet seats you can install on a normal toilet for about $100; more expensive models included heated water and a heated seat sell for $200-400 (remember you may need an electrician to install a GPS outlet in the bath for the heated options).

There are a couple of cheap options advertised on this site (senior care products at the bottom of the page). And not all bidets use cold water, some even have a blow dry option.

Research Medical Supply companies and also bath fixture sites (like Koehler). But, keep in mind that bidets use cold water. B-r-r-r!
