Thank you for your question, steveo! In order to use more than two shower heads, you will need the 6-setting diverter trim, T27999-SS. You will also need to use the T27899-SS trim alone, as T17251-SP is a valve trim with shower head. The shower head for the Dryden series can be ordered separately as model number RP62283.
Best regards, Edward
