I've got two outside drains and both have quite a lot of standing water around them, which can get worse if I forget to unblock frequently. Is there any way to prevent it? Drain one the metal grate sits slightly higher than the concrete - should I just redo the concrete to make it higher? Pic: 
Drain two when using the shower, water splashes out the bowl so leaves the surrounding area a bit wet:
how could I prevent that?
