A wet room is actually a shower room with the shower screen and the tray removed and whole space open with tiled flooring where the water can drain out from an outlet in the floor. Spacious bathrooms become very comfortable as opposed to a closed shower. If you plan on renovating your bathroom and turning it into a wet room, you would need some professional help. They would have to work on the flooring so the water does not collect, preferably using some gradient to help the water flow out, not forgetting to waterproof the rest of the surface.
Why have a wet room instead of a shower
There could be a lot of reasons for this but the most prominent ones are a wet room is a lot larger than a shower or a toilet and you would have more space instead of two smaller rooms, making it a lot more comfortable and a lot less claustrophobic.
A study conducted mentioned that people prefer wet rooms as they are easier to clean than your average shower since there are a lot less corners and edges.
How long till I have one?
If you were putting off getting a wet room since you thought the set up time would be unimaginable, I have some news for you. If you have an experienced team, the right supervisor and all the requirements, you can have your own wet room in a little more than a week.
That being said, you have no reason to still wait it out, get your own wet room now.
