Thank you for your question. The flow rate for the roman tub unit will be determined by the trim kit that is used for the unit rather than the rough valve body. If you should need further assistance with this, please contact our Delta Customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm, CST and Saturday, 8am-5pm, CST.
