Water Bay Shower Handles

[liralen]

The white plastic hot and cold shower handles are cracked and disintegrating n our 08 HR Endeavor. Right from the get-go there were cracks in the handles and the H & C water indicator inserts would pop right off. Now the handles are very broken and while still are usable they are looking like they are on the way out.
Looking through my owners stuff I cant find any info on this plumbing fixture. Haven't been able to locate replacement handles on-line through rv sites. Standard household shower and sink handles look very different and won't fit.

Wondering if anyone else has had a problem with their outside shower handles and where you were able to get replacements.

Thanks
