Thank you for your question, xq89olp! This tub and shower trim kit can be used with any MultiChoice Universal rough valve body in the R10000 Series, however for a shower only installation, a HF (high flow) model is ideal as it does not have a tub spout port. The BX stands for single box model for valves that can be bought in bulk. The R10000-UNWSHF will work best for your installation.
Best regards, Edward
