Even the bathrooms are an exhibition at Frieze London this year. The fair has commissioned London-based artist Gray Wielebinski to create Production (2026), a site-specific work that takes over the fair's public toilets and turns them into what the artist describes as an intimate olfactory environment. Rather than hiding in the plumbing, the artwork announces itself: custom urinal cakes and toilet-rim blocks, developed with the creative studio Dean's Bottom, diffuse two bespoke scents through the washrooms, forcing visitors to encounter art at the exact moment they would least expect it. The piece draws together scent, bodily function, privacy, desire, and surveillance — subjects Wielebinski has circled for years in work about how bodies negotiate intimacy and control in public space. Here, the most mundane infrastructure of the art fair becomes a stage for questions about who feels safe, watched, or welcome in a communal bathroom. Paint, dust, sweat, and the labor of maintenance enter a space designed to conceal other bodily realities, and the disruption is deliberate rather than decorative. The timing gives the work its charge. Britain has been consumed by an acrimonious public argument over access to single-sex spaces — the so-called bathroom wars — with trans people's right to use facilities matching their gender identity contested in courts, in parliament, and across the media. By placing the argument inside the fair's loos, Wielebinski collapses the distance between abstract political debate and the lived, bodily experience of a public toilet. The commission continues Frieze's tradition of artist projects in unexpected corners of the fair, following a lineage that includes Julie Verhoeven's theatrical 2016 takeover of the same washrooms. It also extends Wielebinski's recent experiments with scented bathroom installations, including a threatening metal sculpture at Selfridges and a mechanical-bull rooftop work at Bold Tendencies in Peckham. Production runs for the duration of Frieze London, October 14 to 18, in Regent's Park.
