Architects are responsible to their clients for demonstrating due diligence and face the challenge of showing thoroughness and attention to detail when designing washrooms. One way to demonstrate due diligence is by carefully examining washroom products to ensure they align with the project’s overall objectives.

So, how do you identify what aspects to consider while sourcing the appropriate washroom products, and how do you exhibit the due diligence process?

As a washroom supplier and consultant, we have composed washroom guidelines to explore the intricacies of architectural due diligence in washroom design.

We have also provided a comprehensive checklist within the washroom guidelines to help architects ensure every key aspect of their washroom design is accounted for, considered, and aligned with client expectations and washroom regulations.

Washroom themes to consider

Architects have a lot to consider when designing washrooms. They need to comply with public toilet design standards such as BREEAM and SKA Ratings, which demonstrate the sustainability of their projects, while also aiming to meet other standards like WELL and NABERS UK to ensure that the washroom promotes user wellbeing and energy efficiency.

Architects possess the ability to craft washrooms that reflect their dedication to exceptional design and contribute positively to people’s lives. Therefore, when embarking on a washroom design, it is essential to consider the details for some of the following themes.

Here are some considerations to keep in mind when designing different washroom themes as you review our commercial washroom guidelines:
