Yes, you can put a bathmat down on resurfaced tub/shower floors, but only bathmats that do not have suction cups. You’ll find these bath mats at bath and bed shops that offer specialty items for bathrooms. An alternative to bathmats are bathtub strips that adhere to your shower floor’s surface to prevent slipping accidents. Be aware that once you place bathtub strips down on your shower or tub floor, they may be not removed without possibly damaging the resurfacing job.
