BathCheck helps occupational therapists, mobility specialists, families, and individuals measure a bathroom and assess whether ShowerBuddy transfer equipment may fit — before committing to a purchase or arranging an in-person consultation. Designed for ShowerBuddy bathroom-mobility equipment, BathCheck provides a guided measurement and fit-assessment workflow on your phone or tablet. HOW IT WORKS Work through the guided step-by-step wizard. BathCheck prompts you to measure key bathroom dimensions — width, length, bath height, door clearances, and more — using annotated diagrams that show what to measure. Enter your measurements and BathCheck provides fit guidance for ShowerBuddy equipment (SB1, SB2, or SB2T), including relevant accessories and configuration options for the recorded bathroom layout. Results are based on the information entered and should be reviewed with the assessor or supplier. WHAT YOU GET • Measurement-based fit guidance for supported ShowerBuddy models • Equipment configuration guidance and relevant accessory recommendations • A cushion and sizing matrix — available in metric and imperial — to help select the right seating • The option to email your completed assessment to yourself, a therapist, or a supplier • The ability to save and review assessment history • Detailed product information and PDF reference materials, all accessible offline FOR OCCUPATIONAL THERAPISTS AND MOBILITY SPECIALISTS BathCheck helps prepare for a consultation by collecting the relevant measurements and assessment details in one guided flow. The app supports therapist, supplier, and end-user workflows, and accepts a client reference for record-keeping. LANGUAGES BathCheck v8 is available in English, German, French, and Spanish. The app guides you through language selection on first launch and the setting can be changed at any time. ABOUT SHOWERBUDDY Use BathCheck to collect bathroom measurements and review ShowerBuddy product and accessory information before discussing the assessment with an authorised supplier. BathCheck provides fit guidance; it does not replace professional assessment, product instructions or installation checks.
