Premier League clubs use smart urinals to gain hydration insight

Premier League clubs are now chasing marginal gains even in the bathroom, installing computer‑like urinals that instantly gauge player hydration. The Spanish‑made S‑Urinal, fitted with a screen and sensors, delivers a 0‑100 score within seconds, replacing yesterday’s lab tests for the.

The smart urinals, branded S‑Urinal, were created by the Spanish company Kamleon. The company now provides the system to clubs in England, Spain and France.
How the S‑Urinal works
A display screen sits above each urinal, allowing the player to select his own profile or remain anonymous. The interface lets athletes compare current readings with previous results.
Sensors analyse urine colour, volume and electrolyte concentration. Within seconds the system generates a hydration score from 0 to 100, colour‑coded green, yellow or red, for the player and medical staff.
If a reading raises concerns, the coaching staff can implement an individual hydration plan the same day. Reportedly, The rapid feedback enables immediate medical intervention.
The technology also assists in monitoring athletes who fast during Ramadan, It provides real‑time data to adjust hydration strategies for those players.
Kamleon chief executive Jordi Ferré says the key advantage is speed, replacing next‑day lab analysis with immediate results. He argues that instant feedback can correct hydration issues on the spot.
Club uptake across Europe
Arsenal Football Club were the first Premier League client of Kamleon and have used the S‑Urinal since the 2024/25 season. Reportedly, Arsenal have employed the equipment continuously from the 2024/25 season.
The Athletic Arsenal, Manchester City, Manchester United, Aston Villa and Ipswich Town have installed the equipment. The adoption spread across five clubs in the league.
Beyond England, the system has been installed at Barcelona, Villarreal and Athletic Club in Spain and at Monaco in France. These installations show the technology’s reach across European football.
Ipswich Town executive Mark Ashton says the immediate information on athlete condition is a decisive advantage. He highlights the value of on‑the‑spot data for the coaching staff.
A 2020 systematic review in the European Journal of Sport Science found that 66.2 % of professional players arrive at training dehydrated when urine density is measured. The study noted higher prevalence among men and before training sessions.
The review’s authors concluded that dehydration warrants attention and that players should improve their hydration before exercising. They called for increased monitoring of fluid intake.
Research indicates that fluid loss exceeding 2 % of body mass reduces both physical and technical performance. Such declines underscore the importance of maintaining optimal hydration.
Clubs have turned to smart urinals to detect hydration problems early without waiting for laboratory results. The technology offers a rapid, data‑driven approach to player health.
