What we need in your photo
Some pros know these parts by rote, others don't. We help either way. What actually decides whether we can name the part is the photo, so it is worth the extra thirty seconds at the valve.






Still in the wall, no measurement, or partial views. We usually can't ID these, and it costs you a second trip to the valve.
Shower valves come apart differently and often leave a piece behind. Our step-by-step identification process covers those angles in detail.
What to include
One clear shot of the whole part on a flat surface. If it came out in pieces, lay every piece out together and shoot them in one frame.
A tape measure or ruler in the frame is best. No tape handy? A standard credit card is 3.37 inches long, so eyeball it against one and tell us the number.
We text you when the match is confirmed, so the quote reaches you on the truck instead of sitting in an inbox.
After you hit submit
Real human verification, not an AI guess. One person owns your ticket start to finish.
Usually within an hour during live hours. If a cartridge cannot be confirmed with certainty, we tell you before you order.
The confirmed part and the price land on your phone. Approve it and pay in one tap, or walk away.
Direct to your jobsite or shop. Standard, expedited, or next day depending on location.
