10 speed to 11 speed hub

From a newbie. I have a shimano-type 10 speed hub on rear wheel I purchased from bicycle wheel warehouse a couple years ago. Hub is generic i.e brand is "Pure". I want to convert to 11 speed sram. Is there an adapter or something i can get so 11 speed cassette will work or do i need to get an entire new hub and do a full replacement.
If i have to do that, any idea how much would cost at LBS for parts and labor to rebuild wheel with new hub?

that 11th speed does not matter. if you aint got a couple thousand dollars to spend ,

ride what you have and save a LOT of money to buy a new bike.

It sounds like you get this already, but the issue is the freehub body. 11-speed freehub bodies (Shimano/SRAM compatible) use the same spline pattern as 8/9/10 speed Shimano/SRAM freehub bodies, but 11 speed freehub bodies are 1.8mm wider. So an 11 speed cassette will not work on an 8/9/10 speed freehub body. With a spacer behind the cassette to make up the small difference, you can use a 10 speed cassette on an 11 speed freehub body, however. Some hubs can be retrofitted with 11 speed freehub bodies; the 8/9/10 speed freehub body is removed and replaced by an 11 speed version for that hub. Most cases will require a new hub entirely, however.
