Bathrooms in rental apartments often have limited space, which makes it difficult to accommodate large appliances, such as water heaters, alongside other hygiene items. Furthermore, due to landlord restrictions, major renovations or installing heavy fixtures on the walls are usually not possible.
However, by using smart planning, compact technologies, and clever storage solutions, it is possible not only to ensure hot water in a small bathroom but also to make it look visually more spacious, clean, and bright.
To install a water heater, you should choose instant or portable water heaters instead of large storage models with a capacity of 15–25 liters. Instead, instant heaters with a capacity of 3 liters or special faucet heaters are suitable. These devices take up little space, do not impede movement, and provide quick access to hot water from just one electrical outlet.
You can also utilize unused vertical corners. If there is an empty high wall next to the sink or door, a compact horizontal or slim-design water heater can be installed there. Placing the heater high on the wall frees up space below for use.
To visually enlarge the bathroom, it is recommended to forgo dark curtains and baskets in favor of light shades, such as white or milky. Adding a large mirror to the bathroom helps reflect light, making the small room brighter and more voluminous.
For storing shampoos, soap, and toothbrushes, instead of taking up space on the floor or near the sink, you can use suction cup wall holders and adhesive shelves. This allows items to be placed in the air, leaving the floor completely clear.
Instead of traditional bulky plastic tanks, foldable silicone containers should be used, which can be compressed and hung on the wall after use. Special hangers that attach over the door can be used for hanging towels and clothes.
