Did a search, and it looks like "Geyser" is a brand of instant water heater: http://www.snapdeal.com/products/appliances-geysers-immersion-rods Can you build a box around it? If it needs ventilation, put a screen or vented box over it? Of course, if I'm wrong and this is a water shooting up in the air kind of geyser, then I'd suggest selling tickets and offering it up as a tourist attraction.

What is the dimension of your bathroom? Looks like 4 feet wide, can't make out on length though. Glass partition or tiles partition for shower would help to keep your bathroom clean and dry and revamp look drastically. Wall hung WC is must, again from cleaning and look perspective. If window is not providing any light ( though your photo suggests some light coming from window) this area can also be used for multipurpose. You are welcome for more queries. Tiles selection can be decided based on a theme as well.

Use mirror and apply light colour
