Sorry for the delay. We weren't notified of this question. According to the spec sheet, the seat is 5" high and 9" deep.
We drill the overflow here, so if you had a specific request for overflow placement, we could ask our tubs warehouse if it can be accommodated. For this type of request, we recommend calling us 1-866-8585-2284 to place your order.
