When you do the paint do a third coat of latex or other good exterior paint its should allow you to pressure-wash the walls also do the floor most don't and it causes problems, as for your Sky-Light if you want to keep it there are decorative cement bricks with holes in them use them to form a interior wall and exterior wall, extend the sides to the front then top with Lexan (AKA Poly-carbonate) and finish the edges with hard local stone & mortar as for the door 3 things 1)scrape and paint with again a good latex or other good exterior paint 2) add spongy weather stripping to both the door and the cement (making sure that the two are in the same line to make a strong seal) 3)a god latch so your child and/or any future kids cant just open the door and fall down those steps also to help seal the weather striping. As for the interior if you keep the Sky-Light a string of solar powered LED lights to make it easier and/or maybe even a small workbench and make it your T. A. Outdoors workshop

Looking at the door at about 12: 16, I don't know what is behind you, but I would see about 2 things there. One, cutting some of that concrete back, and resizing the actual door to make it bigger. That would stop rain getting in that way. A rubber seal around the interior of the door could help seal it, as well. But a dehumidifier would help in there, as well as rubber sealing the vent area. What I would do is build up the area around the vent, making it slope down, then laying 1x4's, maybe 2x4's over it, and then a sheet of plywood, and ensure you have enough overlapping to not get water in. You can leave the lower end open, above the concrete, so you can have air circulate in there, without having it open all the time. What you can do, is hinge the cover, so you can prop it up, and put a mirror on the inside to reflect light in. I would put shingles on the outside of the cover. Also, shingles on the door, as well.

Good day. as lighting you can easily hang on the hooks and the eye (at the stairs) on the ceiling a led light hose for outside than the your (walking) light in the bunker with an extension cord at the door or through the air grille. and for the pump I would FIRST measure well for example with a spirit level or better with a laser level where the lowest point in the floor really ISbecause I think that where you now have the hole for the pump is NOT the lowest point in the floor and then you better if you are going to take the trouble for a pump sump it is really at the lowest point. maybe you could suck up the remaining water with a wet / dry vacuum cleaner.

For a Basement I had to stop water leaking in, It came to digging a trench around the entire foundation, then using a rubber based sealant and adding a gravel surround with perforated pipe to a drain field. Took a lot of time and work. But it did stop the water seeping in. I also painted the inside with a wall sealant, primer then house paint. Guess that is why so many homes today are built without Basements. It is a tough and very time heavy solution in a very wet region of the US. Well worth it in the end to stop many problem's that devalues the entire Home if not repaired correctly. You're lucky it is a small area.

You refer to that opening as an air vent. its not an air vent, its an escape hatch for use if the main stairwell gets blocked. Would have had a ladder under it. I have restored a shelter. i kitted my one out with bunk beds, lamps, gas masks, pillows, bedding etc. All period stuff. I have posted my bunker on utube. have a look what i did inside. it may give you some ideas. I have a few videos so look through to find the shelter. again. thats not a vent. its an escape hatch.

You could just put a tarp or plastic sheet over the door until you can get something sorted out. Maybe a shed/roof or just foam weather stripping around the door. The skylight/cover should also be bigger than the surrounding masonry to prevent water from pooling up on the masonry and then seeping in slowly. You could also put a box fan over the rebar grate you installed and leave the door open on drier, sunnier days to help create a circulation and air it out more quickly

Build up a higher frame with either impregnated wood, bricks and mortar or concrete around the door higher then that top part and then a larger door covering say 4 inches out on all sides. Cover the door with roofing felt. It will protect the wood in the door, and it's easy to replace if damaged. That will help stop the water leaking in around the door and the overhand protects any heavy rain from hitting the frame no matter what material you use.

Sika products are excellent. If you completely seal the bunker you will have condensation problems so a shed cupola with louvres on the shaft top will produce a venturi effect regardless of wind direction. That, coupled with a vent of some kind at the door with something to keep the rain off it will draw air down the stairs and up through the vent, the air movement will help to keep it dry and cool in the bunker

IMO, you need to replace that door with a metal door. Then add a metal lip around the whole edge of the cement where the door hits such that the lip is inside the edge of the door. If Im not making sense, look up videos for a tornado shelter and youll see what i mean. I also suggest painting the inside a bright flat ceiling white paint, then stick some battery operated LED lights on the walls.
