I researched these not too long ago and to sum up what I found: small document firesafes are kind of terrible.
There's a few on Amazon for less than $100 like this one but the reviews are usually not all that great. More importantly, the smaller the file safe the less fireproof it is. Anything you can pick up and move yourself is probably only rated for .5-1.5 hours in a fire.
Mine is not commercially offered any longer but this is a pretty good one. SentrySafe HD4100 Fireproof Safe and Waterproof Safe with Key Lock 0.65 Cubic Feet , black https://www.amazon.com/dp/B00GE57DFK/ref=cm_sw_r_cp_api_glt_fabc_5FRBNKG4Y3S8SQET8FXA
You can also double up, use fire safe pouches inside the safe for extra protection.
I would keep everything all these people are suggesting, but I would keep in a fire proof safe. Something similiar to this. You can pick up inexpensive ones from Walmart or amazon for under $50.
In addition to all your Navy stuff you can keep wills, titles, SSN cards, birth certs, and whatever else you don't want to keep in a bank security box.
Do you happen to have a large gun safe that you could put something like this into?

You might also want to think about getting a safe deposit box at a bank/credit union if it's not a document you need quick access to.
> Id quite like to know mine was waterproof and fireproof but still kept in my house. Any cases you can recommend?
Probably your only option is going to be a fire and water rated safe. Something like this provides half hour fire protection. Prices go up from there. I'd probably worry more about securely and redundantly storing your seed words somewhere outside of your home.
When I lived in the Barracks I had something like this SentrySafe HD4100 Fireproof Safe and Waterproof Safe with Key Lock 0.65 Cubic Feet , black https://www.amazon.com/dp/B00GE57DFK/ref=cm_sw_r_cp_api_glt_i_0ET9H8C9D56M3BPPC2XH
If you're just trying to keep a toddler out of it, consider looking into a fireproof box. This one is a decent size, and can be locked and the key put up.

I don't do the best record keeping but this is what I do with any documents involving medical, loan, credit and payment history.
I bought one of these

Then I got this
Avery 47993 Two-Pocket Folder, 40-Sheet Capacity, Assorted Colors (Box of 25) https://www.amazon.com/dp/B0006HVCHC/ref=cm_sw_r_cp_apa_i_96p5CbZ4P2EQE
I took all of one color (blue) and labeled one of them Person 1 credit, person 1 dental, person 1 "year and make of car" and put all the maintenance invoices there. Just repeat till you have a spot to dump all the paperwork for a person. Get another color and repeat for another person.
Things that are joint are a third color, and I have a fourth color for pets. I have folders just dedicated to employement history so if I for whatever reason need to see some pay stubs or documents I signed I should be able to grab the folder and dig there. For me, I think it's fine enough since you rarely need to review those files, you just want to know exactly where to dig when you do.
Not exactly fort knox but if a house burns down your still good with something like this that costs $65
