Just lol at some of these 'pre-meditated' comments.
You can store what ever you want in any of your rooms in your house (as in legal to own items - baseball bats, crossbows, hammers, knives, swords, golf clubs, catapults, snooker cues, cricket bats, machetes
et al). The fact that they can be used as weapons makes no difference. If you happen to store them in your bedroom, then that is absolutely fine. You are legally allowed to store these legal items where ever you want to. If they happen to be the first thing to hand
if you get burgled, and you are
genuinely scared for you or your family's safety - crack on (bear in mind that you will have to do a good job on the perps though).
I am currently typing this in my study - I have many items that can be used as weapons just lying about - 1 x kukri - 1 x crossbow - 2 x cricket bats - 1 x snooker cue - many knives - a random length of two by two - 3 catapults and various lead ammo - four scalpels - a WW2 bayonet and an axe handle. Bear in mind that these are all perfectly normal/legal items. If I were to be burgled, and I was genuinely scared for my family's life, any one of those items would be fine to use to defend us. I have similar stuff stored in the bedroom. Not because I am pre-meditating a break-in, but because I own these legitimate items.
Most of you pussies would be too scared to get into a fight or flight situation anyway.
I also have 2 x machetes stored on the top of my fridge freezer that is right next to my front door. They are kept there to A: keep them out of my daughters reach and B: to be readily accessible to grab and cut some foliage. All perfectly legal
/edit - oh - and op - get yourself a cheap golf bat and keep it near your bed (because everywhere else is too cluttered

)
/edit edit - I forgot the three kitchen knives (1 chef, 1 carving and one chopper) that are also there because they are being sharpened
