bedroom cupboard to wet room

Im my bedroom i have a cupboard. which for a while i thought about having it converted to a Shower Room/Wetroom.

It is 240cm High, by 180cm by 90cm. From advise i had earlier its too small to have a cubicle , hence the idea of wetroom.

I want to try and gauge what materials would be required to get a rough price estimate for doing that. Before i get a friend to see if the plumbling side is possible.
Open to any kinds of idea, i havent much idea of whats involved or what to think about

Seems like a big job to me. thousands of pounds

You can get shower trays up to 1600 x 800, this sort of thing




About £700 for the glass and £300 for the tray. Rules for electrcity being isolated away from the shower are the same as the bathroom zones.

Consider your water service and drainage from the location your considering, that tends to be the big challenge.

Just found this, 1800 x 900mm baby



Moods Cesana Tecnostar 1800mm Walk-in Wetroom a cool £2300

I have just finished my own wet room project in a similar room in a house I have just sold (!). I managed to complete it for well under £1000 including the tiles. I used a pre-formed shower tray which I tiled and some waterproofing compounds. It was a few days work but made the house sale much easier!

Good luck!
