Actually, the best thing is buy another one for the bathroom even if you get this one repaired. Breaking the seal, like you did, means the thing can no longer be relied on to repeal moisture. It may stay dry inside; it may not. If not Bad Things happen. Like electrocution.
Stay safe & toss the sucker.
