Ablution facilities should be accessible to all users without discrimination. However, some ablution facilities among wheelchair users were inaccessible due to poor design, mismatched anthropometry, and lack of design guidelines. Previous studies showed that the existing ergonomic ablution workstation improvements were required relating to the user's arm, neck, and trunk. Three structured objectives of this study were to design the final ablution workstation concepts, analyze the 3D modeling with Rapid Upper Limb Assessment (RULA), and prototype fabrication with testing among wheelchair users. The observation, survey, Product Design and Development, and Quality Function Deployment (QFD) methods were used to identify user requirements and target technical specifications for prototype design development. The 3D models of the ablution workstation were analyzed by Finite Element Analysis (FEA) to evaluate the reactions of the applied forces. The RULA method was then used to investigate the ergonomic risks among the 5 th , 50th, and 95th anthropometric percentiles for both genders and three selected wheelchair models, including the standard wheelchair (Wheelchair A), light-weight wheelchair with a fixed armrest (Wheelchair B), and foldable armrest (Wheelchair C). The prototype was fabricated by considering the physical and functional elements to maximize comfortability during ablution. The prototype was tested by 20 wheelchair users, and were interviewed to identify user satisfaction and comfort level. Based on the findings, most ablution facilities at observed mosques, malls and highway Rest and Service Areas (RSA) in Terengganu and Pahang were inaccessible among wheelchair users. The wheelchair measurements indicate that Wheelchair A has the highest dimensions compared to other wheelchairs. The FEA found that maximum Von Mises Stress was (61.52 MPa), displacement (0.44 mm), and safety factors (15 ul) for the load applied. Meanwhile, the RULA analysis of generated concept indicates that adjustability improves the comfortability among all users’ percentiles and genders for Wheelchair C. The comfortable adjustable range of the Work Surface Height (WSH) was determined between 55 cm to 78 cm based on the RULA analysis, and respondent testing. The testing shows that 95% of the interviewed respondents were very satisfied with the comfortability of an adjustable ablution workstation same as the RULA findings. In conclusion, there was a significant relationship between the adjustability, users' anthropometric, and wheelchair models that influence the comfortability of the ablution workstation, which improves the body postures of the arm, neck, and trunk while performing the ablution. Thus, this study hopes to become a worthy social contribution to improve comfort for Person With Disabilities (PWDs) ablution facilities in Malaysia.

| summary | Ablution is an obligatory ritual activity to clean specific limbs to perform prayers. Ablution facilities should be accessible to all users without discrimination. However, some ablution facilities among wheelchair users were inaccessible due to poor design, mismatched anthropometry, and lack of design guidelines. Previous studies showed that the existing ergonomic ablution workstation improvements were required relating to the user's arm, neck, and trunk. Three structured objectives of this study were to design the final ablution workstation concepts, analyze the 3D modeling with Rapid Upper Limb Assessment (RULA), and prototype fabrication with testing among wheelchair users. The observation, survey, Product Design and Development, and Quality Function Deployment (QFD) methods were used to identify user requirements and target technical specifications for prototype design development.
