If your breast reconstruction requires a short hospital stay, your nurse may help you shower before you are discharged. They can ensure that your incisions are well-protected and also help you see how you need to handle drains and bulbs if necessary. Usually, it's possible to shower 24 to 48 hours after the breast reconstruction procedure, and, after that, you can shower once every day if you would like. Your aftercare instructions only have restrictions around submerging the surgical area.
