So you buy a nice two shelf bookcase but it’s wobbly and you know it won’t hold much. I’ve recently gotten one and my solution was to put L-brackets on it. After installing about 8 of these brackets at the cojoining parts of the shelving, it is now completely stable and ready for use.
Buy some area desinfectant and regularly use it on the bathroom floor and toilet seat.
The first is to prevent warts under your feet, the second is against infektions like akne or your skin. Works pretty well so far.
Be carefull not to accidentally pour the desinfectant INTO your toilet, it might react with something. Use a paper towel to hold the chemicals instead.
Also, make it a habit to wipe down your shower walls after a shower. This prevents gunk build up and mold. It will be harder if you don’t clean it regularly.
