Caligirl I am SO glad you made that phone call!!!!
I had LTKR on Jan 20, and I must say I am STILL using the raised toilet seat (I saw someone posted you don't need it for a single, HA!). I have removed it twice and tried but my quad muscle is just not strong enough yet, so back on it went. My insurance co would not pay for a raised toilet seat so PT ordered a commode. Then you remove the bucket and set THAT over the toilet: raised seat and bars to hold on and push up! There is a splash guard in the bucket to use. Fantastic!
