Where To Wee: making every public toilet in the UK easy to find.

Where To Wee is a free map of public toilets across the United Kingdom: 15,000+ of them, in 380+ towns and cities, with opening hours, step-free access and baby change. It runs on the web and as an app on the App Store and Google Play.

I designed it, built it and run it. No ads, no subscription, no premium tier, and there never will be.

I moved to Bournemouth in 2025. New city, no idea where anything was, and one day I really needed a toilet and could not find one.

It sounds trivial. It is not, if you are pregnant, managing Crohn’s or IBS, disabled, elderly, or out with a toddler. It is the invisible thing that decides whether you leave the house at all. And nobody had mapped it properly.

I gathered every public toilet I could find into one dataset, then wrote a geocoder to clean the addresses and give each toilet real coordinates. I open-sourced it as address-geocoder.

The web app is Next.js on Vercel and the phone app is Flutter. Underneath, Supabase holds the data: council records, community reports and verification tiers, so people can see how far to trust each entry. When Brighton & Hove City Council came to me, its official dataset went in as council-verified.

Within months it had 35,000 users: 22,000 on the website and 13,000 in the app. It has earned 779,000 search impressions without a penny spent on ads.

BBC News featured it, BBC Radio Solent had me on live twice, and it took me to the main stage of the NADP Annual Conference to talk about accessible spaces.
