Thank you for your question! The cartridge assembly that comes with the Delta Sandover Tub and Shower 144748 faucet has a Rotational Limit Stop, which can be adjusted to allow for less or more hot water. However, at the hottest setting the handle will rotate to about the 10 o'clock position. For help adjusting the RLS, please refer to page 8-9 of the Maintenance/Installation document linked below.
