Thank you for your question. We recommend installing the Delta 9159T-AR-DST with the handle on the right. You may install
it with the handle on the left side, but the temperature adjustment will be opposite of the standard operation for single handle faucets. You could compensate for this by swapping the hot and cold supply lines under the sink. However, the red/blue button on the handle will no longer indicate the correct temperature.
