I'm trying to update the bathroom in an old house as cheaply as possible.
The plaster wall around the shower-over-bath has taken water damage (seems to get hit whenever the shower is used, shower curtain doesn't block it all) and needs replacing and protection against further damage.
My idea was to stick a sheet of acrylic plastic or perspex over the area that gets wet, as a cheap splashback and waterproofing solution. Other areas in the bathroom already have some plastic sheeting that presumably serves the same purpose, so it wouldn't look out of place.
I checked Bunnings and the cheapest piece of splashback acrylic available is $99. The area I need to cover is small, maybe 60cm x 20cm, and I feel that a cheaper solution should exist.
Does anyone know of a cheap source of plastic material that can used for waterproofing? Looks aren't really important - I just want something that works and is cheap.
something like this?
