Brotan,

Maybe u should combine your storeroom and Bathroom together.. Make it into a bigger bathroom with walk-in cupboard to act as store. That's what i did to the common bathroom of my soon going to be ex-bungalow.

Yeah, going through ur bathroom is better than your bedroom! You dont want the dust from the storeroom to go into your bedroom each time u open the door. Moreover, just make it big enough to walk in.. My common bathroom is about 9x9ft, and i have tall cupboard on one side to accomodate all my detergent, toilet paper, mobs, my underwater camera casing, telescope stand etc.. a lot of storage space.

Mine is big enough for the ladder. But I would caution u against putting your power tools in there as moisture in the bathroom may make them rust. That's what happen to all my camera lenses. They were accidentally left there after the renovation. Fungus grew on them and I had to spend a few k cleaning them and replacing the lense components.
