One of the things that I’ve been trying to figure out is how best to build the bathroom in my tiny house. In the US, it’s common in new houses or renovations to use a shower enclosure that’s made out of a single fiberglass moulding. This makes it seamless and ensures there is no gap for water to leak through. Unfortunately these aren’t common in the UK and, when you can find them, they’re several hundred pounds, which is outside my budget. So, I figured I’d put in a shower tray and find a way to waterproof the walls.
I had considered just using plywood and coating it in marine epoxy. Not the prettiest answer but wouldn’t be too expensive, and would be reasonably easy to do. I don’t want to use tile because it’s too heavy and I need to keep the weight down to the trailer limit. I’m also not looking for one of the heavy ‘stone’ shower trays which are most common now. Then I discovered plastic wall panelling: It’s lightweight, warm to the touch so there’s very little condensation and available in nice designs. It’s still quite expensive though, and looking round suggested about £300 to make a 3 sided enclosure.
However, Ebay has, once again, helped me save money. I picked up a brand new shower tray for £12 from someone nearby. It’s white, 76cm on a side and will define the width of the bathroom. I also found some reduced wall board, probably and end of line, but enough to complete the shower, the ceiling above and possibly a splashback in the kitchen. It looks like blue tiles. With the edge seals and fittings it came to just over £100, and now all I need to do is keep my eye out for a suitably sized shower door, mixer valve and waste trap. I already have a low flow shower head with an on/off button. Now, how shall I heat the water….
