Prefabricated Bathroom Unit (PBU) Acceptance Framework

PBU designs have evolved over the years and may also involve the use of alternative materials in its fabrication. To ensure that the different PBU systems being used at development sites are reliable and durable, BCA has set up an acceptance framework consisting of building regulatory agencies as well as industry experts to ensure that the design and materials used are robust and can meet the minimum standards set.

The PBU acceptance framework consists of the following steps:

1. Acceptance by Building Innovation Panel (BIP)*

BIP application process flow * From 1 Apr 2023, BIP will discontinue accepting common PBU and PPVC systems for evaluation. Common PBU and PPVC systems refer to systems which are similar in designs to past accepted BIP systems, or systems that are already adopted in Singapore. For more information, please refer to this BCA circular or contact the BIP secretariat.

(a) Check for performance requirements – PBU suppliers and manufacturers who intend to supply their PBU systems to development sites must first ensure that their PBU system meets the PBU performance requirements. For the performance requirements, please refer to the prevailing Code of Practice on Buildability.

(b) Submit application for evaluation to Building Innovation Panel (BIP) – Applicants should submit the completed application form and supporting documents to the Building Innovation Panel. The secretariat will seek comments from regulatory authorities and a presentation session will be arranged, if necessary. Applicants are to follow-up to address all agencies’ comments.

(c) In-Principle Acceptance – If accepted, relevant letters of In-Principle Acceptance (IPA) will be issued to the PBU supplier/manufacturer. 

(d) Listing on BCA’s website – View list of PBU systems with In-Principle Acceptance.

2. Accreditation by PBU Manufacturer Accreditation Scheme (MAS)

In addition, the production facilities producing PBU systems must be accredited under:
